Effect of saturated air and nitrox diving on selected parameters of haemostasis.

The objective of the study was to evaluate decompression stress after air and nitrox saturated divings on the basis of the parameters of haemostasis. Before and after each diving the following examinations were performed: blood platelet count, aggregation, fibrinogen level and coagulation factors VII, X and XII. After the air saturated dives a slight reduction of factor X and XII and of fibrinogen was observed. Evaluation of haemostatis may be one of the basic elements in the assessment of decompression sickness risk.
