2How a Dive Medical Statement works
The process of completing a Dive Medical Statement typically begins with the diver answering a series of 'yes' or 'no' questions regarding their personal medical history. These questions cover a broad range of health areas, including past surgeries, chronic conditions, medication use, and any symptoms that might indicate an underlying issue, such as asthma, heart disease, diabetes, or neurological disorders. The diver is expected to answer honestly and to the best of their knowledge.
If all answers are 'no', indicating no known medical conditions that could affect diving, the diver usually signs the statement to confirm their fitness. This self-declaration is often sufficient for many recreational diving activities. However, if the diver answers 'yes' to any of the screening questions, or if there are uncertainties, the form directs them to seek a medical examination from a physician. This physician should preferably be experienced in hyperbaric or dive medicine, as they can accurately assess how specific conditions might interact with the underwater environment and pressure changes.
The physician will then evaluate the diver's condition, potentially conduct further tests, and ultimately determine if the individual is medically fit to dive. If cleared, the physician signs off on the medical statement. This signed clearance is then presented to the dive operator or instructor, allowing the diver to participate in dive activities safely. It's important to note that the medical statement is a dynamic document; any significant changes in health require a new evaluation.
3Common Medical Conditions and Diving
| Condition Category | Example Conditions | Potential Diving Risk | Typical Recommendation |
|---|---|---|---|
| Respiratory | Asthma, chronic bronchitis | Air trapping, lung overexpansion injuries (pneumothorax) | Physician evaluation for severity and control |
| Cardiovascular | Heart disease, high blood pressure | Cardiac events under stress, reduced exercise tolerance | Cardiologist evaluation, stress tests |
| Neurological | Epilepsy, history of stroke | Loss of consciousness, seizures underwater | Neurologist evaluation, often a contraindication |
| Ear/Sinus | Chronic sinus issues, perforated eardrum | Difficulty equalising, barotrauma | ENT specialist evaluation, surgery may be required |
| Mental Health | Severe anxiety, panic disorder | Panic attacks underwater, impaired judgment | Mental health professional evaluation |
4What a Dive Medical Statement means for your liveaboard trip
When planning a liveaboard trip, completing a Dive Medical Statement is a crucial preliminary step. Most reputable liveaboard operators, following industry best practices and insurance requirements, will provide you with a copy of the statement, often the RSTC Medical Statement, well in advance of your departure. They expect you to review and complete it honestly.
If you declare any medical conditions, the operator will typically require a physician's clearance, sometimes within a specific timeframe (e.g., within 12 months of the trip). It is imperative to obtain this clearance before you travel, especially to remote liveaboard destinations where access to qualified medical professionals for last-minute assessments may be impossible or severely limited. Failure to produce a required medical clearance could result in being denied diving privileges onboard, or even denied boarding, with no refund.
The Dive Medical Statement serves not only as a safety measure for the individual diver but also for the entire group. By ensuring all divers are medically fit, the liveaboard crew can better plan dive activities, understand potential emergency scenarios, and maintain a safer environment for everyone. It also helps the crew understand if any diver might require specific assistance or if certain dive profiles should be avoided for their safety.
5Medical Consultations for Diving
| Condition | Specialist Consultant | Key Considerations | Outcome Focus |
|---|---|---|---|
| Asthma | Pulmonologist | Severity, trigger control, exercise-induced component, medication compatibility | Assessment of bronchodilator response under pressure |
| Diabetes | Endocrinologist | Blood glucose control, risk of hypoglycaemia, type of insulin/medication | Management plan for diving, stable glucose levels |
| Heart Condition | Cardiologist | Cardiac function, stress test results, presence of PFO, medication effects | Tolerance for exertion, risk of arrhythmias |
| Ear/Sinus Issues | Otolaryngologist (ENT) | Eustachian tube function, history of barotrauma, tympanic membrane integrity | Ability to equalise pressure, absence of infection |
| Mental Health | Psychiatrist/Psychologist | Stability of condition, medication side effects, risk of panic, claustrophobia | Absence of acute symptoms, ability to cope with stress |
6Common misconceptions
Myth: Filling out the form is just a formality; nobody actually reads it. Fact: Dive professionals, including liveaboard operators and instructors, take these forms very seriously. They are legally and ethically obligated to review them to ensure diver safety. Providing inaccurate information can have severe consequences for your safety and invalidate insurance.
Myth: If I answer 'yes' to anything, I'll automatically be disqualified from diving. Fact: Answering 'yes' simply means you need a physician's evaluation to determine if your condition is compatible with diving. Many conditions, once properly assessed and managed, do not prevent individuals from diving safely.
Myth: I don't need a medical statement if I'm already certified. Fact: While you may have completed one for your initial certification, health can change. A new medical statement, or at least a review, is often required for new courses, guided dives, or liveaboard trips, especially if a significant amount of time has passed or your health status has changed.
Myth: My regular doctor can always sign my dive medical clearance. Fact: While a regular doctor can complete some parts of the form, it is highly recommended and often required for complex 'yes' answers to consult a physician knowledgeable in dive medicine. They understand the specific physiological stresses of diving and how medical conditions react under pressure.
FAQ
What is the purpose of a Dive Medical Statement?
The primary purpose is to screen divers for medical conditions that might pose a safety risk or be exacerbated by the underwater environment. It ensures individuals are medically fit to dive safely.
Do I need a new Dive Medical Statement for every liveaboard trip?
You typically need to complete a new statement if your health has changed significantly since your last one, or if the liveaboard operator specifically requests a recent one, often within a year. Always check with your specific liveaboard provider.
What happens if I answer 'yes' to a question on the medical statement?
If you answer 'yes' to any question, you will usually be required to obtain medical clearance from a physician, preferably one with experience in dive medicine. They will assess your condition and determine if diving is safe for you.
Can I dive with a medical condition if my doctor signs the statement?
If a physician qualified in dive medicine has assessed your condition and provided written clearance on the medical statement, then you are typically cleared to dive. It's crucial that the physician understands the physiological demands of diving.
Where can I find a Dive Medical Statement form?
Dive Medical Statements are usually provided by dive centres, liveaboard operators, or dive training organisations (e.g., PADI, SSI, RSTC). You can often download a copy from their respective websites.
Is the Dive Medical Statement confidential?
Yes, your medical information is confidential. Dive operators and instructors only need to see the final signed clearance from a physician if required, not necessarily the details of your medical history, unless directly relevant to an emergency.
