Testing of Biomarine CCR 1000 Closed Circuit U.B.A.,

Abstract

Breathing resistance and CO2 scrubber duration tests were performed. The maximum breathing resistance measured at 198 FSW during a breathing rate of 30 breaths per minute with a 2.0 Liter Tidal Volume breathing through a Mk VI mouth-piece was -15 centimeters of H2O during inhale and +14.5 centimeters of H2O during exhale. The CO2 scrubber duration was determined under three conditions at 200 FSW 32 degree F water with 0.85 SLPM CO2 add rate with a duration of 2 hours 40 minutes; 32 degree F water with a 1.2 SLPM CO2 add rate and a duration of 1 hour 57 minutes; and finally in 72 degree F H2O with a 0.85 SLPM CO2 add rate and a duration of 7 hours, 10 minutes.
