Evaluation of the comfort of spontaneous respiration through three ventilator systems.
The use of intermittent mandatory ventilation and continuous positive airways pressure systems is widespread. The comfort of spontaneous ventilation through three systems, with a variety of humidifiers, has been evaluated. The use of demand flow systems and the introduction of some humidifiers caused considerable discomfort from fluctuations in the airway pressure. It is concluded that continuous flow systems are preferable and that fluctuations in airway pressure should not exceed 2.5 cm H2O.
