Bench testing of a new hyperbaric chamber ventilator at different atmospheric pressures
Intensive Care Medicine, 05/30/2012
Lefebvre JC et al. – The IPER 1000 ventilator attempted to deliver stable tidal volume by adjusting the opening of the inspiratory valve in proportion to atmospheric pressure. Adequate compensation was observed, albeit only within a predictable range, which can be reliably predicted for each setting and ATA level combination. Setting a tidal volume outside this range can result in an unwanted decrease in minute ventilation.
