Title: Hypercapnia during Deep Air and Mixed Gas Diving.
Author: Sterba, JA
Abstract: Elevated carbon dioxide (CO2) levels in the blood, hypercapnia, can limit work capacity and diver safety. The risk of hypercapnia was determined in six U.S. Navy divers with underwater bicycle ergometery at 190 feet of sea water (FSW) breathing air, plus 300 and 1,000 FSW breathing helium-oxygen using a helmet (oro-nasal mask/demand regulator). Peak-to-peak mouth pressure (Delta P) and breath-to-breath end-tidal partial pressure of CO2 (PETCO2) were measured during sixth min of exercise (total work = 193 watts). Keywords: Hypercapnia, Carbon dioxide, Alveolar, Monitoring.
