Pressure controlled ventilation pdf writer

Aim of this study: was to compare between volume-controlled and pressure-controlled ventilation in COPD patients undergoing laparoscopic cholecystectomy. Methods: A case control study was conducted on 60 participants aged between 18 and 60 years, diagnosed with COPD and scheduled for laparoscopic cholecystectomy. This paper purposes to create and simulate Mathematical Model (MM) of Pressure Controlled Ventilator (PCV) signal. This MM represents the respiratory activities and an important controlled parameter during mechanical ventilation—Positive End Expiration Pressure (PEEP). The key feature is, THE VENTILATOR ONLY CONTROLS THE PRESSURE SUPPORT LEVEL. The rate, volume, cycling time and so forth are controlled by the patient. Ypu have some degree of control over the tidal volume: you can adjust the pressure support value (the higher it is, the higher a tidal volume the patient will inhale).
