[Servo-ventilator 900 B with modified registration site for measuring the ventilation pressure. A possibility for reducing the inspiratory resistance during SIMV (author's transl)]. 1981

J Link, and K Voll

The inspiratory resistance, which a patient has to overcome while doing SIMV and CPAP with a Servoventilator 900 B, can be lowered by a simple modification of the ventilator. This modification is done by measuring the ventilation-pressure at the patients side of the humidifier. Measurements of pressure and flow demonstrated that, with a flow of 11 s-1 a 66%-reduction of the inspiratory resistance can be achieved.
