Stop the Bleed Month...

 Did you know that May is ‘Stop the Bleed’ month?

To support ‘Stop the Bleed’, we’re going to take a closer look at blood and how to manage a bleed in this week's blog. Starting with a bit of biology…

The human body contains around 5 litres of blood, depending on the individual’s size and weight, and this makes up approximately 10% of their overall body weight (cue jokes about ‘heavy blood!). Blood is broken down into the 4 key constituents of Red Blood Cells, White Blood Cells, Platelets and Plasma, and it has multiple functions. 

The most common function is the blood’s ability to carry oxygen (and glucose) around the body. Without this transport mechanism, individual cells would be starved of oxygen and begin to die. From here, whole body systems would begin to fail, leading to a global state of hypoxia and ultimately death.

Blood is contained in the Circulatory System. This is the network of arteries, veins and capillaries that allow the blood to be transported all around the body, delivering oxygen to the cells. When we talk about bleeding, or haemorrhage to use its technical term, the first thing we need to consider is whether the bleeding is external or internal. 

External bleeding is probably the easiest of the two to manage. External bleeding is visible, and we have a host of tools and techniques available to us to stop external blood loss quickly and effectively. 


Step 1: Identify the source of the bleeding – this may not always be obvious if it is dark; if the casualty is wearing clothing or coveralls, or if the bleeding is in an anatomical location that you cannot immediately see.


Top Tip: Always check their back, groin and under the armpits!


Step 2: Try to apply direct pressure. Direct pressure needs to be firm and focused. Ideally this should be done with a gloved hand and may be used temporarily, while someone else finds kit/dressings in the First Aid Kit. For small wounds, such as a burst varicose vein, the direct pressure may be as simple as one finger tip.


Top Tip: Before applying pressure to a wound, always have a quick look to ensure there is no foreign object embedded in the wound, such as a piece of broken glass!


Step 3: Transition the pressure. It’s blooming hard work to maintain manual direct pressure on a bleed for any length of time! It is also not ideal from a logistical point of view, especially if you need to move the patient. Modern pressure dressings are exceptional at maintaining focused pressure on a wound when applied correctly, though this transition is likely to be a 2-person job. 

The Olaes bandage is highly effective and will control almost all external bleeds. 

(Watch this space for a how-to guide on the Olaes many uses - we love them almost as much as triangular bandages!)


Top Tip: Pressure dressings are simple to use – but only if you know how! Make sure you’re familiar with your kit before you have to use it in an emergency. 


Step 4: If the bleed is so severe that a pressure dressing is not controlling the bleeding, then an arterial tourniquet may be required. Tourniquets are used to entirely stop the blood flow to a limb. They are placed just above the wound (between the wound and the heart) and are tightened until all bleeding stops. Once applied, seek immediate topside support regarding next steps!


There may be certain situations where you approach a patient and blood is literally hosing out. Under these circumstances, it may be appropriate to use a tourniquet as the first line of defence. 


Top Tip: A genuine arterial tourniquet such as the Combat Application Tourniquet (CAT) costs approximately £30. They cost this much for a reason; because they are tried, tested and manufactured according to strict quality assurance processes. You can buy a fake CAT tourniquet online for £2.99, but you run the risk of it breaking when you most need it. Avoid cheap, fake tourniquets – lives depend on the quality of your kit.

What if the bleeding is in an awkward place such as the groin or the neck? 


Bleeding in areas such as the groin or neck are referred to as junctional bleeds. These areas don’t always lend themselves to the use of tourniquets or pressure dressings. Instead, a Haemostatic dressing such as Celox Rapid may be required, and applied using a technique known as wound packing. Wound packing involves actively pushing haemostatic gauze into the wound to apply direct pressure deep into the source of the bleeding. 


Modern haemostatics contain various compounds, often derived from crushed shellfish shells. The compounds promote blood clotting and are highly effective.


Top Tip: Haemostatics can safely be used on people even if they have a severe shellfish allergy. The proteins that cause the allergy are removed during synthetic processing, making them perfectly safe. They can also be used for people taking blood thinning medications or with conditions such as haemophilia.

Internal bleeding occurs when blood is escaping from the circulatory system but leaking into cavities or tissues within the body. It can be very difficult to identify and a casualty can bleed to death without a single drop of blood being seen?


Internal bleeding is often caused by blunt force injury in trauma and because it’s often harder to detect, and we might need to become something of a medical detective in order to find and treat the bleeding effectively.


So how will I know if the casualty has an internal bleed if there’s no blood visible?


When we bleed, our bodies will try their best to maintain a normal balance. This means the body will compensate for a reduced volume of blood by working harder. The respiratory rate increases to try and get more oxygen into the system quicker and the heart rate increases to compensate for the reduction in circulating blood volume by pumping faster. These are subtle, but important, signs that the patient could be bleeding internally and going into shock.

So, where does the blood go?


If you’re in front of a potentially bleeding casualty, remember the phrase:


Blood on the floor and four more!


Blood visible on the floor tells you there’s an external bleed, and if it’s enough to make you catch your breath, it’s significant! But, if there are signs making you suspicious of an internal bleed, or the mechanism of injury is suggesting it, then we need to check the four other places that a casualty could bleed into. You can find out more about mechanism of injury in this previous blog https://www.redsquaremedical.com/moi-mechanism-of-injury

  • Chest cavity. This could cause a life threatening condition called a haemothorax.
  • Abdomen. This could be from any number of organs or viscera, such as the spleen or liver.
  • Pelvis. The pelvis has a rich blood supply and some major blood vessels pass through it. High impact forces can cause disruption causing significant, life-threatening haemorrhage
  • Long bones. A broken Femur (thigh bone) can bleed approximately 1.5 litres of blood. If you break both of your legs, that’s 3 of your 5 litres potentially lost. This can be life-threatening.

Signs & Symptoms of Internal Bleeding:


  • Mechanism of Injury - how did they become injured?
  • Pale skin – this is due to the body diverting blood from the skin (less important) to the vital organs (very important).
  • Bruising. Note the area, location and any pattern associated with the bruising.
  • Deformity – perhaps an uneven pelvis, one leg longer/shorter than the other or feet splayed outwards.
  • Increased respiratory rate – to take in more oxygen.
  • Increased heart rate – to pump what’s left of the blood around quicker.
  • A reduced level of consciousness – if the brain is starved of blood and oxygen, the patient will gradually become unconsciousness.


There’s nothing we can do about internal bleeding – right?... WRONG!


This is a phrase that is sometimes (incorrectly) taught on First Aid courses. Although we cannot directly fix the bleeding, our actions can certainly help to minimise further blood loss, prevent disruption of that all important first clot and optimise physiology until we can get the casualty to definitive care.


  • Firstly – recognise internal bleeding. This may be subtle, with a slow progression. Sometimes internal bleeds may onlMinimise patient movement. Minimal handling techniques are becoming more recognised in modern medicine. If we do have to significantly move a casualty, try to do it once and as early as possible in their care.
  • Give Oxygen if it’s available.
  • Splinting suspected fractures can reduce pain, anxiety and blood loss.
  • Remember that a pelvic binder is a treatment device, not a packaging device. If you suspect a pelvic fracture, use it early.
  • Keep the casualty warm. Cold prevents the blood from clotting and can impact on the bleeding.

Plan early to medevac your patient to definitive care.


Top Tip: Know your vital signs. When haemorrhage occurs, the body will compensate. This compensation is often the first sign that something is wrong. It can be subtle, so conducting regular observations and noting these on an Obs Chart will allow trends to be highlighted at a glance.


If you’d like to get involved with Stop the Bleed, this link will take you to a short online course
https://www.stopthebleed.org/training/online-course/. It’s a fun bit of CPD, but is from the USA, so remember to call for help using the appropriate phone number for the country you’re in - though 999, 911 and 112 will all work in Europe! Also, tourniquets can now be positioned as close to the wound as possible, to preserve the maximum tissue above the wound.


Such an important skill that we should all make sure we have in our toolkit....

Welcome to our December blog, which is all about the recovery position and how to manage an unconscious casualty who is breathing normally. Unconsciousness is a medical emergency as the person is very vulnerable and may not be able to manage their own airway effectively. We also need to think about the cause of unconsciousness. Is it a simple fainting episode due to illness? Is it a massive hemorrhage causing hypovolemic shock? Or is it due to some kind of external factor or injury? This blog looks at how to manage an unconscious casualty. So, if we have a casualty who is unconscious, but who is breathing normally for themselves, and we’re not suspecting a serious injury, the recovery position is the best position to use while monitoring them. The recovery position keeps their airway open and makes sure that vomit or liquid won’t cause them to choke.

All the guest blogs! When we started adding blogs to our website back in early 2021, we did a little feature on each of our instructors of the time. They’re quite a fascinating bunch and the series proved quite popular amongst our followers. In addition to our amazing instructors, we work with some utterly incredible human beings all over the world, and the idea of sharing their stories grew and developed into what eventually became a monthly guest blog. It’s been interesting to find out more about how medical care at sea or in remote locations features in their work, and to discover a few fun facts along the way. This month, we thought that it might be a fun idea to give you a chance to go back into the archives and review all the guest blogs over the last few years! Maybe even let us know which your favourite one is?

We’ve taken a look at the 2023 Casualty Summary Report from the Maritime Authority of the Cayman Islands (MACI) to see what kind of incidents and trends their data shows us, even with relatively small data sets, and how this may be able to transfer to our own risk assessments and actual practice. You can find the report here: Cayman Maritime Report 2023 The first thing we noted was the authors note that the data is split out into incidents. This means that one incident may include a number of events. So a collision and any resulting injury is one incident, but is reported as two events, or more, if more than one person is injured. It made us wonder whether this method of reporting by an authority represents how incidents are reported onboard and whether it should be a consideration? Of course, for any set of statistics presented at the moment, we also have to consider the COVID-19 pandemic and the impact this has on trends including that period. While essential shipping continued, the cruise and superyacht sectors reduced activity and staffing, often to a skeleton crew while anchored somewhere. So this will be reflected in the historic data sets that we analyse from 2019 to 2021 and may not accurately reflect increases and decreases during and since then. In some situations, we may need to look further back for accurate data. We also need to consider whether increases in incidents and events is also down to increased reporting - suggesting an improvement in the awareness of reporting requirements and greater engagement from the industry and individual sectors - this can only be a good development. Since 2020, the type of injury has been recorded in 8 different categories, with hand and foot injuries topping the leaderboard, closely followed by head, body, and back injuries. So if you were looking to run drills, or practise medical skills, these would be the key areas to cover. Only one death was an occupational accident, and is being investigated here: MAIB Investigations (search for case #9229607). It relates to a fall down a ventilation shaft on a bulk carrier in a Greek shipyard. The full report was still pending at the time of writing. Merchant ships are heavily regulated by a number of authorities, and the requirements for personal protective equipment and safe systems of work are enforced and applied to reduce accidents and incidents onboard. This has led to a lower reporting of incidents than in the commercial yacht sector. Could there be room for improvement here in this area? We certainly think so. Many of the hand and foot injuries reported can be career ending or life changing, but are preventable. Follow up has shown that there is a link here with injuries being sustained when inappropriate or no PPE was used. The supply and use of appropriate PPE is mandatory on vessels subject to the MLC and it’s worth remembering that some PPE can be produced in styles and designs compatible with the aesthetics of a yacht if required! On a much wider scale, a lack of transparency and standardisation globally can affect the collection of data and the issue of under reporting. While the MACI figures may be accurate, we need other accurate figures to compare them to, in order to build a bigger picture across the world as we have in aviation. From December 2024, the Maritime Labour Convention (MLC) will be enforcing an amendment so that seafarer deaths will be recorded and reported annually. The MACI and Cayman Islands Shipping Registry produces a number of safety flyers that are publicly available HERE that may be useful. In summary, analysing data can sometimes result in more questions than answers. But even this can lead to interesting and important developments that result in improved safety and reduced incidents and accidents onboard. Key points to take from this report are: Use the correct PPE for the task. Employ approved systems of work and risk assessments for the task. Reporting is key for safety in the future of our industry. Enjoy a night ashore, but don’t over do the cocktails! As always, if you’d like any input on medical training onboard or ashore, or drills that you can run yourselves, please just get in touch.

Welcome to our latest guest blog where we’ve been chatting to James Griffiths, General Manager of Ocean Operations for Scenic Group and finding out more about what happens behind the scenes in order to keep a fleet of luxury expedition ships running. Here’s what James told us… As General Manager of Ocean Operations, I’m responsible for the operations of our fleet which includes four ships in service with around 850 colleagues. I currently live in Mumbles, near Swansea in the UK, but due to the nature of my work I spend a significant amount of time living in Croatia. Prior to this role, I spent many years working at sea and worked up through the ranks to Captain and over the last 15 years, my main focus has been on polar expedition travel. I hold a master mariner certificate of competency in addition to a degree in engineering and a post graduate diploma in law. Part of my job is to work with our medical service provider (Red Square Medical) to ensure that our ships are offering medical services that are appropriate for their deployment, and this can often be to some of the most extreme and remote locations around the world. It’s extremely varied, though during the COVID-19 pandemic, I came ashore when our operations paused for a significant period of time. I was fortunate enough to be given the opportunity to lead the restart of our Ocean Operations, which included setting up everything from a company to manage the ships, to selecting our crewing, medical, helicopter and submarine partners and providers, amongst many other things. Our areas of operation, and the nature of our cruises (expedition), plus having aircraft and submersibles onboard some, do mean additional elements involved in the management of these ships. You could say that this current position is more of a happy coincidence than one that I actually planned for! In some ways this is a great positive - I do think it’s possible to plan a little too much and then be disappointed if things don’t go quite the way you had imagined. But there’s no danger of that here!

Back in February 2022, we brought you one of our very first guest blogs from Simon Lawton, a Paramedic who has swapped out his ambulance for a Superyacht! You can read the original blog here: https://www.redsquaremedical.com/superyacht-paramedic-a-guest-blog-from-simon-lawton Over the last 2+ years, we’ve followed Simon’s career, and some of you may even recognise him as he does put a Red Square Medical instructor hat on from time to time. But, as for all healthcare professionals, Simon has to keep his skills up to date. So, we asked him to tell us a bit more about how he juggles this along with a rota onboard. Here’s what he told us… I’m originally from Stoke-on-Trent in the UK and trained as a HCPC registered Paramedic. I’ve spent almost 5 years working at sea now, with almost continuous employment on three different vessels, after leaving the ambulance service in 2019. My first role was as a Paramedic/Deck hand on Superyachts, and I now work as a Medical Officer on a maritime vessel. Even before I applied to become a Paramedic, I intended to complete my studies to help find employment in a remote or offshore environment. I had always been attracted to the idea of being able to travel the world while earning a salary. Working at sea has meant that I have travelled extensively, earnt a higher salary, and have a better work/rest balance than would be possible in a role on land. Note: At the time of writing, a qualified Paramedic’s starting pay in the UK was £28,407 and Simon’s old rota was 2 days, 2 nights (all 12 hours) and 4 days off with very inflexible annual leave. This year I decided to carry out some continual professional development (CPD) at a hospital in Mexico, to keep my skills up to date. I was interested in travelling to find out more about how healthcare services are provided outside the UK and Europe. The CPD activity in Mexico allowed me to do exactly that, while caring for and treating a wide variety of patients who had either self-presented in the emergency department, or been conveyed to hospital by ambulance.

Welcome to our September blog, and as we all start (in the UK at least!) to think about adding a few layers for warmth, we’d like to talk about getting naked! Well, to be more specific, getting bra’s off. Fact: Women are dying because bystanders are less likely to carry out CPR on women than men. Research shows that women are 27% less likely to receive CPR than men and if a defibrillator is used, their chance of survival is affected by bra’s being left on. Most of us have never had the chance to train using a female manikin. The #BraOffDefibOn campaign aims to address the inequality in CPR for women and we’re supporting it.

In August, we brought you a Guest Blog from Mark Hannaford, the founder of World Extreme Medicine. This month, it’s the turn of another of the key WEM faculty members… introducing Dr Will Duffin. Hello everyone, I’m Dr Will Duffin and I’m a GP in Devon in the UK. I’m the Joint Medical Director of World Extreme Medicine (WEM) and the Lead Medic for the US CBS TV show ‘Survivor’ - for Seasons 43, 44, 46 and 48, which is also through WEM. Extreme Medicine is healthcare that is delivered across the full spectrum of remote, austere and challenging environments. This includes high mountains, deep oceans, jungles, deserts, polar, low earth orbit and refugee camps… the list is endless. Being a part of the wider Extreme Medicine community through WEM has been a portal into new worlds of possibility and opportunity in my medical career as an NHS GP. It’s a huge privilege to treat patients in a remote setting. You get to do proper ‘hands on’ medicine that truly tests your clinical skills, risk management and decision making. Even basic techniques and principles done well can transform patient outcomes. That’s the big reward. I graduated from Bristol Medical School in 2008 and completed my GP Training in Cornwall, UK in 2016. In between, I spent 18 months in Australia to gain as much emergency department experience as I could, whilst doing Wilderness Medicine Courses. I landed my first expedition gig 12 years ago when I was post-FY2 (Foundation Years follow on after qualifying as a doctor). I covered a Kilimanjaro Trek after another doctor dropped out at the last minute. Once I had this under my belt, I was able to leverage this experience to get the next trip. So, I soon found myself providing regular medical cover for various commercial and charity sector expeditions. These expeditions have taken me all over the world: Kilimanjaro, the Peruvian Andes, the Himalayas, Northern China, Eastern Europe, Myanmar and Madagascar. One highlight was working as the private doctor for a Luxury Trans-Siberian Train! Though I became frustrated having to constantly wrangle annual leave to go away, so I made the switch to being a freelance (locum) GP, which has given me the flexibility I need. I joined WEM in 2018 after responding to a Facebook Ad for the ‘Survivor’ job. I was invited to a selection weekend in the Peak District, which is when I first met Mark Hannaford WEM founder and CEO and Dr Joe Rowles, WEM’s other Medical Director, and it all went on from there. Early on, I was given the opportunity to lead on the content for the annual World Extreme Medicine Conference and our various podcasts and webinars. Through doing this, I have met a colourful cast of characters; other extreme medics who are as audacious as they are inspirational! We have a lot of fun at the conference every year, learning from one another. https://worldextrememedicine.com/registration/wem-conference-2024 (Note from the RSM team – the conference is highly recommended and well worth a visit!)

Last year, the Red Square Medical team descended on the World Extreme Medicine (WEM) conference for the very first time. We’d been aware of this unique organisation for many years, but just not had the chance to get involved. Liz was involved in a panel discussion and spoke at the conference, and we came away literally buzzing with enthusiasm - our first impressions were that WEM is a place with no ego’s, where everyone wants to learn, and is willing to share. We met some of the most fascinating people ever and can’t wait to go back this year. But what about the person who started it all… We spoke to Mark Hannaford, founder of World Extreme Medicine and its far reaching impact. Here’s what he had to say. I’ve been involved in expeditions, working in low resource environments and extreme medicine for the past three decades! My family was made up of generations of seafarers from Cornwall although I was brought up variously in Devon, Antigua in the Caribbean and the Middle East; reflecting my father’s job as a Master Mariner. My father was at one time the youngest captain aboard the UK’s largest registered vessel, and my grandfather was Harbour Master for Malta and the first in that role in Plymouth at the start of Queen Elizabeth’s reign. I wear a number of hats but primarily I am the founder and CEO of World Extreme Medicine, and the annual WEM Conference. I also founded the MSc in Extreme Medicine at the University of Exeter and Graduate Certificate program at Bouvré College of Health Sciences, Northeastern University, Boston.

Women’s health is a huge topic, while it’s true that in the maritime sector women make up just 2% of seafarers at sea, up to 34% of the shore based staff are female. Looking at the bigger picture, women’s health directly affects just under half of our population globally, and indirectly (whether you like it or not!) the other half, we thought it was worth a blog about some of the issues, and the taboo’s, that could be affecting our maritime workforce and the women in our lives. It's common knowledge that women experience huge hormonal changes at puberty and menopause, both of which can have significant physical and mental health impacts. In the UK, there is a growing discussion and openness about peri-menopause (the years before periods stop altogether) and how for some women, this has devastating effects across all aspects of their lives, including work. Of course men experience changes at puberty, but their later life changes are less significant and generally don’t affect their ability to work. In December 2023 the World Health Organisation (WHO) issued a statement to advise that every year, at least 40 million women are likely to experience a long term health problem caused by childbirth. So there’s a good chance that we all know one or more women affected, or if you are female… this could be you. As part of a special series on maternal health, the study showed a high burden of postnatal conditions that persist in the months and years after giving birth. These issues include more than a third of women experiencing pain during intercourse, urinary incontinence (8-31%), anal incontinence (19%), anxiety (9-24%), depression (11-17%), perineal pain (11%), a fear of childbirth (6-15%) and secondary infertility (11%). All in all it doesn’t paint a great picture of life after childbirth for some women. If any of your workers experience these issues, either on or off shore, it could have a significant impact on areas of their working life and it’s something they may be reluctant to open up about. Even before childbirth, we may take it for granted that contraception is available, certainly in the developed world. But in developing countries where sexual violence is not uncommon, contraception is considered lifesaving due to the high level of unsafe abortions carried out. Around 13 million women (and girls) under 20 give birth annually and complications in the pregnancy and birth is a leading cause of death. Consequently abortion is an option, but this carries its own huge risks.

We just love speaking to and finding out more about the people who inspire us and we guarantee that this month’s blog will not disappoint! We first got in touch with Wendy Sullivan via LinkedIn and thought she seemed like a pretty awesome human. Wendy and her company, Maritime Medical Solutions in Australia, certainly share the same outlook as Red Square Medical. Fast forward a couple of years and we’re now collaborating on a project in Australia and the Pacific Islands. What we’ve learnt along the way is simply fascinating and Wendy has kindly agreed to share her story with us… Here is Wendy’s Guest Blog: I was born in Canada, grew up in Africa and now call Australia my home. I feel lucky to live in paradise where the weather allows us to be on the water year-round. I had to work hard to gain my Australian citizenship and I credit my work in the marine industry with giving me a pathway to stay in Australia permanently. It took years of hard work and uncertainty to gain my residency and is still one of the achievements I am most proud of. I started sailing in Canada and since emigrating to Australia gained my professional and commercial qualifications as a vessel master, marine engine driver, trainer and assessor. I also have a Diploma of Paramedical Science, ship masters medical qualifications, business administration and development and there is still so much more to come.
