Objective To develop the underwater decompression table for the 32％ nitrogen-oxygen mixed gas (32％ oxygen and 68％ nitrogen) diving operations.Methods In accordance with the Haldane theory,the assumed time units,the classification of tissue compartments,the nitrogen super-saturation safety coefficient and the selection of methods used for the calculation of 32％ nitrogen-oxygen mixed gas diving table were properly selected,and the calculating method for the diving decompression table was thus firmly established.Through animal experiments with 376 goat times and 94 compression profiles,Doppler ultrasonic gas bubble detection and ethological changes of the animals were monitored or observed,following decompression to the surface.Results By using the developed decompression table,no abnormal ethological changes in the animal behavior could be detected after compression and decompression to the surface,and the Doppler bubble sound grade was almost zero.Pulmonary and cerebral pathological observations indicated that there were no congestion and edema in the tissues.Conclusions The decompression table developed with theoretical calculation seemed to be safe and reliable.
