[Computation of low-risk compression. Computation model and results of experimental decompression research]

1. The relationship between tolerated nitrogen oversaturation and ambient pressure is practically linear. 2. Tissues with short half-times have a higher tolerance than tissues with long half-times. 3. The human body can be regarded as consisting of 16 compartments with half-times from 4 to 635 minutes for nitrogen and from 1.5 to 240 minutes for helium. 4. The coefficients for calculation of minimal tolerated ambient pressure for a given PN2 in the tissue can be deduced directly from the half-times for nitrogen. 5. The results of 573 simulated air dives and 544 real dives in mountain lakes are in accordance with the computed limits of tolerance. 6. The ZH-L16 system is applicable to all exposures with air or oxygen-nitrogen mixtures. 7. Adaptation to breathing of oxy-helium or trimix is simple.
