초록 ▼

A method and apparatus for initiating a positive-pressure-assisted inspiration phase in response to a patient\s inspiratory effort, and independently of the absolute pressure at the time of the inspiratory effort, since the absolute pressure may vary from patient to patient or depend upon a particular mode of operation of the respiration system. The invention apparatus includes a differentiator circuit for obtaining a time-differentiated pressure signal, and a circuit for detecting a change in the sign of the slope of the differentiated signal. The patient\s inspiratory effort is manifested as an increased rate of pressure drop, and this shows up as a change in the sign of the slope of the differentiated pressure, which is detected independently of absolute pressure, and is utilized to initiate an assisted inspiration phase. The apparatus also includes circuitry for detecting a predetermined drop in pressure, from the time of detection of the inspiratory effort, to ensure that minor variations in the pressure signal will not trigger a spurious inspiration phase.

대표청구항 ▼

For use in a respiration system, apparatus for detecting a patient\s inspiratory effort independently of absolute pressure, said apparatus comprising: pressure sensing means, for sensing system pressure near the point of delivery of gas to the patient, including means for generating a pressure signal therefrom; first electrical means for generating from said pressure signal a first output signal indicative of a first time differential signal; second electrical means for generating a second output signal indicative of the sign of the second time differential of said pressure signal, whereby said second output signal is indicative of an increase in the rate of pressure drop during an expiration phase of the patient breathing cycle; third electrical means responsive to said second output signal, for generating a third output signal indicative of the change in the system pressure; and comparator means for comparing said third output signal with a reference value indicative of a predetermined pressure drop, and developing a control signal to initiate an assisted inspiration phase of the breathing cycle when said third output signal reaches said reference value.
