ADJUSTMENT OF VENTILATOR PRESSURE VERSUS TIME PROFILE FOR HOLDING BALANCE OF COMFORTABLENESS AND EFFICIENCY

摘要

PROBLEM TO BE SOLVED: To provide a ventilator for adjusting the degree of a support of a servo controller by adjusting a profile of a pressure waveform similarly to a pressure modulation amplitude. SOLUTION: When the servo controller increases the degree of the support by increasing the pressure modulation amplitude, the controller gradually generates the rectangular and hence efficient pressure waveform. When the controller decreases the degree of the support by reducing the pressure modulation amplitude, the controller gradually generates the smooth and hence comfortable pressure waveform.
