Fatigue? That’s just another word for tiredness… isn’t it?

Well, you might be interested to hear that medically speaking, tiredness is something that happens to everyone. It's an expected feeling after certain activities or at the end of the day. Usually, you know why you're tired, and a good night's sleep solves the problem. 

In contrast, fatigue is a daily lack of energy over a longer period, described as unusual or excessive whole-body tiredness, not relieved by sleep (tired all the time) and it can become a serious issue, leading to exhaustion.

We’re guessing that everyone reading this can recognise that they have experienced fatigue and exhaustion at some point! All of the Red Square Medical team certainly have.

If you’re tired, you will still have a bit of energy, but you're likely to be forgetful and impatient. You may also feel muscle weakness following work/exercise, which should be alleviated by rest. 

Fatigue symptoms include difficulty concentrating, anxiety, a gradual decrease in stamina, difficulty sleeping and increased sensitivity to light. Over time, it can lead to skipping social engagements that were once viewed as important.

Exhaustion can lead to confusion resembling delirium, emotional numbness, sudden loss of energy, difficulty staying awake as well as difficulty sleeping, and complete social withdrawal.

This means it’s important to recognise the difference between tiredness and fatigue because fatigue is a marker that your body isn’t able to keep up and it could develop into exhaustion. It’s particularly important in our maritime environment when safety is paramount and small errors in judgment could have catastrophic results. Long shifts, 24 hour working patterns, stress and anxiety, being away from home for extended periods, diet, lack of exercise, working where you live and feeling isolated, can all contribute to fatigue. 

Failing to recognise the difference between tiredness, fatigue and exhaustion could lead to you trying an inappropriate approach to combat the issue, potentially making it worse. As an example, exercise could relieve tiredness, but for those suffering from fatigue or exhaustion, it could decrease their ability to adapt. 

Similarly, caffeine or other simple stimulants could help to cope with tiredness temporarily, but if you’re suffering from fatigue or exhaustion it can fool your body into thinking it has more energy than it really does. 

Learning to recognise the symptoms in colleagues as well as yourself could be a valuable skill. 

If you do spot symptoms, it’s important to seek medical advice and there are some simple steps that you can take. It might be helpful to think about:

  • Parts of your life, such as work and family, that might be particularly tiring.
  • Any events that may have triggered your tiredness, such as bereavement or a relationship break-up.
  • How your lifestyle may be making you tired.
Generally, the causes of tiredness and fatigue will fall into the following categories:
  • Psychological causes - more common than physical causes and include stress, emotional shock, depression and anxiety.
  • Physical causes - include health issues such as iron deficient anaemia, under active thyroid and sleep apnoea. Plus pregnancy, being over or under weight, carbon monoxide poisoning, cancer treatments and the side effects of some medications. 
  • Lifestyle causes - too much alcohol, too much or too little exercise, working nights and napping in the day.
Once you’ve ruled out any medical issues that are causing tiredness or fatigue, take a look at some simple things that might help. 
For example, if you don’t do any exercise, try to start including some light exercise into your daily routine. Cut down on alcohol - both men and women should stick to no more than 14 units per week. 

Try to reduce stress by finding something that brings you joy - and that doesn’t have to be something big or even make sense to anyone else. Just something that you do for yourself because you enjoy it. At sea, this could be to watch a sunrise or sunset and appreciate it, taking a walk around the deck with some deep breathing exercises, reading a book or writing a journal. The possibilities are there but might take a bit of effort initially to find out what works for you and incorporate into your daily or weekly routine.

We know how easy it can be to slip, pretty much unnoticed, from normal tiredness to fatigue and exhaustion on board and out at sea. So please take 5, and do a quick evaluation of yourself and think about your colleagues and friends too.

With that, it’s goodnight and sweet dreams from the Red Square Medical team and if you’d like any further suggestions, please get in touch.

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.

Reflection is an essential part of medicine and our regular followers will know that every year, we like to take a look back and assess where we started and how far we’ve come over the last 12 months. So, please join us on our whirlwind recap of 2024 as we get ready for a fabulous 2025… In 2024 we increased the number of STCW training clients to 4 organisations in 6 locations. We delivered STCW training at all levels to over 250 students. We delivered bespoke training to over 75 students onboard Superyachts and cruise ships. We delivered first aid at work or oxygen training to over 40 students, on land and on ships.

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.
