Prognostication of the Risk of an Occurrence of Decompression Stress following Air Dives

The objective of the work was to investigate the impact of postprandial hypertriglyceridemia on the risk of an occurrence of decompression stress following hyperbaric air exposures. The study was conducted on 55 men aged between 20 and 48 years old (the average age 31.47±5.49 years), with a BMI value within the range of 20.3 – 33.2 kg/m (25.5±2.58 kg/m). The participants’ blood was drawn for tests 2 hours after a meal. The following parameters were defined: morphology, aspartate aminotransferase (AST) activity, alanine transaminase (ALT) activity, total cholesterol concentration and triglyceride concentration. Following each exposure, three Doppler ultrasound examinations were performed in order to determine the occurrence and intensification of decompression stress. Decompression stress was noted in 30 men. Postprandial hypertriglyceridemia and hypercholesterolemia were proven to raise the risk of occurrences of decompression stress after hyperbaric air exposures. The application of logistic regression allows a mathematical prediction of the risk associated with an occurrence of decompression stress following hyperbaric air exposures.
