What is a Dive Medical?


Scuba diving can include some risks, and some medical conditions can make the danger of death while scuba diving much higher. A Dive Medical primarily focuses on cardiac, pulmonary, and neurological conditions, and general overall fitness issues, which may put a diver at increased threat for decompression sickness, pulmonary overinflation syndrome with ensuing arterial gas embolization, and other conditions such as loss of consciousness, which could lead to drowning. Those who suffer, or are predisposed to, any of these conditions, should be evaluated by a physician prior to undertaking any dive training.

Dive certification agencies have collaborated with medical professionals to develop a medical questionnaire that provides a basis to determine if a diver requires further evaluation. At the same time, if a diver has any concerns about your diving fitness not represented on the questionnaire, the diver should consult with their physician before diving.

If the questionnaire indicates that a physician is required to conduct a dive medical certification, then the doctor will examine the diver’s ability to survive unexpected underwater or on-surface emergencies as well as the risks of death, unconsciousness, impaired judgement, disorientation, impaired mobility, or decompression sickness associated with diving with a particular condition or disorder.

During the examination, both age and overall physical fitness are considered as well as vision, dental, ear nose and throat, and balance. Blood pressure, lung function, and a range of other medical conditions are also assessed. A urine test will also be carried out to detect previously undiagnosed conditions including diabetes and pregnancy.


Any conditions or disorders highlighted in the Questionnaire will be clinically assessed regarding their risk to the diver, as will any medications currently being used by the diver. Medications are particularly important in terms of the increased risks associated with the medications used while diving.
