The pneuPAC hyperbaric variant HB: a ventilator suitable for use within a one-man hyperbaric chamber.
We describe the performance of the pneuPAC hyperbaric variant HB, a ventilator designed for use in a one-man hyperbaric chamber. The ventilator delivered minute volumes of 11-23 litre at 1 atm abs to 7.6-16 litre at 2.5 atm abs. The delivered minute volume may be controlled easily from outside the chamber by manipulation of the ventilator rate, 11.5-31 b.p.m.
