Medical skills, first aid equipment and the ability to communicate, impact the outcome of an offshore medical emergency. In the Injury and Illness Survey of past Bermuda Races the extremities, especially fingers and toes, were sites most at risk for injury. Sea sickness and sunburn were common. Infections, migraine, diabetic dehydration, and airway obstruction requiring a Heimlich maneuver were encountered. Offshore crew training should stress the importance of avoiding hypothermia, dehydration, fatigue, and seasickness.
Conditions not encountered in these races must also be considered. The incidence of malignant melanoma, as well as other skin disorders directly related to excess sun exposure has increased alarmingly among sailors, according to records of the US Coast Guard. Asthma, life-threatening allergic reactions, heart attacks, strokes, seizures, and surgical emergencies can be added to the long list of potentially treatable events one might have to deal with on an offshore passage. Anticoagulants (blood thinners), which are used to treat blood clots or cardiac conditions such as atrial fibrillation, can turn a minor knock on the head into an untreatable and fatal hemorrhage in the brain. Finally, while conditions, such as falling overboard and drowning or being hit on the head by the boom or mainsheet during an accidental jibe have high mortality rates despite best rescue efforts, they are mostly preventable by always using an inflatable harness and tether in the former case, and by a permanently installed and always engaged preventer, in the latter. A culture of safety and prevention is the best way to minimize the risk of injury and illness.
Acknowledging that not every medical situation can be handled safely and successfully at sea, a single person, the Medical Officer, not necessarily a medical professional, has the responsibility of caring for the ill or injured crew member offshore, preparing the vessel and the crew for any likely medical emergency and being aware of the presence or absence of medical and rescue resources. Significant medical conditions of individual crew should be on record and known to the medical officer before departure One or more crew members should have valid First Aid certificates.
Medical training to improve the skills of a lay person who has become a yacht’s Medical Officer is available in a number of commercial programs ranging from first aid to medical wilderness courses. Medical training is important because on a small boat there is no “911” as we have come to know it and expect. CPR training is urged for all crew members.

The Medical Officer must make sure that the following are available onboard the vessel:
1. Information from each crew member about significant medical conditions, allergies and necessary medications are easily accessible;
2. Medical and surgical skills appropriate to the voyage;
3. Appropriate medical supplies - reference books, a medical/surgical kit and medicines (addenda 1-3), appropriate to the level of medical training on board; 4. An appropriate emergency communication system and training of the entire crew as to the proper use of the equipment
Another critical role is that of the Communications Officer who links the boat to outside medical help and rescue services. VHF and Single Sideband radios and a suitable satellite system for voice and/or email communication are usually found on an offshore yacht. More than one crewmember must know how to use the equipment and whom to call. If satellite communications are available, it is advised that emergency rescue phone numbers be readily available and programmed into the sat phone. During the Bermuda Races 2002 - 2024, competitors by pre-arrangement used the emergency department of a major medical center to provide remote 24 hour medical advice to yachts. Similar services are available commercially and should be considered by vessels planning offshore passages.
RADIO PROCEDURE:
a) Coast Guard Emergency/Distress Frequencies VHF - Channel 16; Single Sideband – 4125, 6215, 8291,12290 kHz
b) Radio broadcast protocol
1. Tune to correct frequency.
2. Say “pan-pan…pan-pan…pan-pan” (urgent)
Or “may-day…may-day…may-day” (life-threatening)
3. This is (yacht’s name) – three times.
4. Give call sign - twice.
5. Give latitude/longitude or other specific location.
6. State type of vessel.
7. State nature of emergency.
When to Call USCG directly using standard emergency procedure 1. Unresponsive or minimally responsive patient-lethargic obtunded or confused 2. Obvious major trauma (amputation, severe head or facial injury, or severe fracture)
3. Respiratory distress – difficulty or unable to breath, rapid breathing, pale, ashen, sweaty
4. Cardiac distress – chest pain, pale, sweaty, difficulty breathing, elevated heart rate HR >130, low blood pressure (<80 if able to measure)
5. Severe or facial burns
6. Obvious stroke symptoms – facial weakness, arm or leg weakness, speech difficulty, confusion
emorandum
Incident Presentation: information needed by a remote physician or rescue organization
1. Level of Consciousness – orientation to person, place, time and event (alertness and awareness)
2. Chief complaint - primary problem
3. History of present illness and mechanism of Injury – what happened and what are the patient’s symptoms.
4. Patient’s medical history – problems, medications, and allergies
5. Physical findings – vital signs (heart rate, blood pressure, temperature, respiratory rate, oxygen saturation), then problem focused exam
6. Interventions – what have you done ; medications given
Additional emergency Data:
1. Distance from port or rescue (by sea or air)
2. Medication and medical equipment on board
3. Medical skill level of crew (MD, RN, EMT, APC)

*Special thanks to William Strassberg, M.D., Chair of CCA Safety and Seamanship Committee for his contribution to this Memo.
** Covid 19 is a changing situation. Please refer to CDC guidelines for up-to-date recommendation
***Lidocaine with epinephrine should never be used for local anesthesia in fingers and toes due to the possibility of digital vascular constriction and necrosis.
**** Due to potential side effects of seasickness medications, these medications should be trialed on shore prior to use on board.
