- Abstract: Objective To observe effects of simulated air-breathing fast buoyancy ascent escape training on the vital signs of submariners.Methods A series of escape training,totaling 69 man-times were carried out at different depths of 3,10,30 and 50 m.Blood pressure,pulse rate and respiratory rate of the submariners were measured before training.the moment after termination of training and 10 min after surfacing from the escape chamber.Results When compared with those of pre-training,most of the indices concerning systolic pressure,diastolic pressure,pulse rate and respiratory rate of the submariners increased quite significantly,with statistical differences (P<0.01) the moment after termination of training.Nevertheless,the values almost returned to normal,10 minutes after training.Conclusions Simulated air-breathing fast buoyancy ascent could elevate blood pressure,pulse rate and respiratory rate of submariners.However,these changes were all transient.The profile of our submarine escape training proves to be safe and reliable.
