Figure 2. Representation of procedures for intervention (A) and sham (B). Intervention (A): 10 min of compression to 2.0 ATA, followed by 3 cycles of 20 min of oxygen at pressure with 5 min on air between cycles, followed by 10 min of decompression (total of 90 min). Sham (B): 5 min of compression period followed by 80 min at 1.3 ATA with air, then a decompression period of 5 min (total of 90 mn). ATA, atmosphere absolute.
