3.5.2 Live Monitoring Parameters The following Live Monitoring Parameters are displayed at the section 2 of the screen: Paw AV (cm H2O): Paw AV is the average patient airway pressure measured during the last 60 seconds. This measurement is monitored by the ventilator at all times and modes. The number on the display will be updated every 15 seconds. Mve (L): Minute volume is the total exhaled volume for the last 60 seconds as calculated using the last 8 breaths. The Mve will constantly change as the value is recalculated and displayed at the end of exhalation phase. When unit is first turned on or resumed after pause or on selecting a new mode, the Mve calculation will be based on first then second then third and so on until the 8th exhaled tidal volume when the above logic will be followed. Rate (BPM): Rate (BPM) is the rate at which breaths are delivered in one minute. It is the monitored breath rate calculated by measuring the time interval (Tb in seconds) between 2 breaths. Rate (BPM) = 60 / Tb. The number is updated after each breath. This number will be displayed for both mandatory and spontaneous breathing phases. Vte (ml): Tidal volume is the volume exhaled from the patient in mandatory, spontaneous or PSV (Pressure Support Ventilation) breaths. Vte is calculated by the measurement of the entire expired flow displayed as a volume. Vte display will be updated at the beginning of the next inspiratory phase (The end of exhalation phase).
