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....

In basic first aid classes, there is great emphasis on not moving a patient under any circumstances. But is this always right? Our Paramedic friends tell us about times they have arrived on scene to find an elderly faller virtually held down onto the icy ground they slipped on because they think it’s best. Or a care home resident who is unharmed, wriggling around but just unable to get themselves off the floor. Of course, if the person is ill or injured, care must be taken to prevent the condition from worsening, but certainly in our maritime environment there may be times when we MUST move a patient for both their and our safety and wellbeing. We may even need to move them into a safe space (such as lowering from height) before we can assess them and work out the potential injuries and associated risks. But how do you know when to move them? Or how to move them safely? Here are some situations where moving the patient might be essential: Immediate danger – if the patient is in immediate danger, and if it’s safe for you to help, they should be moved away in some manner. This could be due to fire, an unstable structure, in the water, an otherwise unsafe location. Cardiac Arrest – the patient must be on or moved to a hard, flat surface in order for compressions to be effective. Ideally with a bit of space for a team to work around them. To prevent further harm – if the patient is in a position where they could worsen, or something life threatening could develop, you may need to move, or at least reposition them. This could be due to vomiting, choking on blood, unable to maintain their own airway and could be as simple as sitting them up or rolling them over. Self-extricate – if the patient is able to self-extricate, they should do so. There has been a lot of recent research into this area and old techniques challenged and changed. For instance, in a road traffic collision, if the patient can get out of the car themselves, they should. You can find out more here: https://phemcast.co.uk/2022/09/15/extrication/ Worsening conditions – if the weather and environment change, then you may need to move your patient. For illness or injury, keeping someone warm is important, if not vital. Even in a tropical climate, a trauma patient can cool more rapidly than you think and those rain squalls may pass quickly but do a lot of soggy damage in a short time.

At the time of writing, the Caribbean superyacht season is in full swing and the Mediterranean season is looming just around the corner in a few months time. It can be a stressful time for any crew, from the most senior to the most junior - and we could all do with a little help to manage stress and our response to it. We’ve written a number of blogs about mental health and things you can do to help manage your own stress and mental health, and when to seek help. We’ve listed them at the end of this blog. But did you know that we can also offer a one day, onboard training session, for the whole crew? Stress Happens! is run in conjunction with the super experienced team at Impact Crew, so you benefit from a business, leadership and team perspective, together with the medical and wellness input. Stress Happens! was developed in response to feedback from superyacht crews and has been running for 4 years. It can be delivered in one day and is suitable for crew at any level. It’s also delivered onboard, making it easy to facilitate the whole crew to attend. The aim is to focus on mental wellbeing and stress, providing tools and techniques to help you to manage your own stress, helping others to manage their stress and knowing where to turn for help if it’s needed.

In this month's blog, as aching hearts aren’t just related to Valentines Day, we’re taking a look at chest pain! Chest pain is a common reason for calls for an ambulance or to shoreside, and frequently it’s not actually due to cardiac (heart) issues. But you will often hear Paramedics tell their patients that they have done the right thing; they would genuinely prefer to get to a patient and find the chest pain is a minor issue, than it being cardiac, and too late! Last year, we wrote this blog about 20 causes of chest pain (plus a bonus one!). Some of the conditions described are acute (sudden onset), some are chronic (long term), some need urgent attention, others not so much. But we should always take chest pain seriously and make sure a full assessment is done at the earliest opportunity to rule out anything life threatening. Typical symptoms of cardiac chest pain and/or a heart attack are:

From Flu jabs to far flung destinations… Vaccinations are a hotly debated topic across the globe, particularly after COVID-19 and the rapid response to the need for a vaccination to help reduce the burden on the health services in different countries. While the majority of healthcare workers and the general population support the ‘prevention is better than cure’ line of thinking, and therefore vaccinations, there are others who are determinedly against vaccinations for any disease, whatever the risk of mortality and death may be. In the UK, the BCG (Bacillus Calmette-Guerin) vaccination used to be given to all children in their teenage years to protect against tuberculosis. The vaccine has been so successful that TB is virtually eradicated now, and the majority of cases are due to migration. Now it’s only given to those deemed at high risk - babies and children at high risk, those travelling to high risk regions and adults coming into the UK from high risk countries. Depending on your country of origin, you should receive a range of vaccinations as a child or young adult. This will most likely include diphtheria, tetanus, polio and whooping cough, hepatitis and HIB (Influenza type B). Then MMR (measles, mumps and rubella), the pneumococcal vaccine (meningitis, pneumonia and sepsis) and HPV (Human Papilloma Virus) with a variety of boosters along the way. At the other end of the scale, the over 65s can receive vaccines for shingles, pneumococcal vaccine and respiratory syncytial virus along with flu and covid vaccines.

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!
