Abstract:
:We modified a Penlon Nuffield 200 for use in a monoplace hyperbaric oxygen chamber by feeding back the chamber pressure to the reducing valve of the Nuffield 200. This provides a compensating mechanism, allowing the ventilator to deliver adequate tidal volumes at pressures of up to 3 atmospheres. We report the laboratory testing of the ventilator and our experience of ventilating two patients with carbon monoxide poisoning. Although compensation is not complete the modification is adequate for short-term clinical use in patients in whom the airway is compromised but who need hyperbaric oxygen therapy.
