Progressive symptomless hypothermia in water: possible cause of diving accidents.
Progressive symptomless hypothermia in water: possible cause of diving accidents Unexplained loss of consciousness, often followed by death, has been common during diving in British waters. Forty-two such deaths were noted by Childs and Norman" and no likely cause for them has been established. We describe here progressive symptomless hypothermia which developed during one of a series of fully ...
متن کاملOpen water scuba diving accidents at Leicester: five years' experience.
OBJECTIVES The aim of this study was to determine the incidence, type, outcome, and possible risk factors of diving accidents in each year of a five year period presenting from one dive centre to a large teaching hospital accident and emergency (A&E) department. METHODS All patients included in this study presented to the A&E department at a local teaching hospital in close proximity to the l...
متن کامل[Recreational diving accidents in Sweden].
Even if recreational diving is gradually becoming safer, the 2-6 fatalities each year is the most serious problem in recreational diving. Human factors are behind 75% of the fatalities and medical problems seldom cause fatalities. On average 40 recreational divers are treated with recompression each year. Signs and symptoms are in general mild and only few sequelas are seen. The number of traum...
متن کاملHypothermia, the Diving Reflex, and Survival
This paper reviews the contributions of hypothermia and the mammalian diving reflex (MDR) to human survival of cold-water immersion incidents. It also examines the relationship between the victim’s age and MDR and considers the protective role played by hypothermia. Hypothermia is the result of a reduced metabolic rate and lowered oxygen consumption by body tissues. Although hypothermia may pro...
متن کاملRepetitive paired stimulation of nasotrigeminal and peripheral chemoreceptor afferents cause progressive potentiation of the diving bradycardia.
Hallmarks of the mammalian diving response are protective apnea and bradycardia. These cardiorespiratory adaptations can be mimicked by stimulation of the trigeminal ethmoidal nerve (EN5) and reflect oxygen-conserving mechanisms during breath-hold dives. Increasing drive from peripheral chemoreceptors during sustained dives was reported to enhance the diving bradycardia. The underlying neuronal...
