Live monitoring parameters are displayed in Section Two of the ventilator’s screen. This section allows the operator to observe real-time outcomes based on settings adjusted in Section Six. These values are continuously updated and provide essential information about the patient’s ventilation status.
Key Monitoring Parameters
1. MVE (Minute Volume, in liters)
-
Represents the total volume of air exhaled over the last 60 seconds.
-
Calculated using the average of the last eight breaths.
-
Value is recalculated and updated at the end of each exhalation phase.
-
When the unit is first powered on, resumed after a pause, or when a new mode is selected, the minute volume calculation will begin incrementally from the first to the eighth exhalation, then continue as a rolling average.
2. VTE (Tidal Volume Exhaled, in milliliters)
-
Measures the volume exhaled by the patient during a breath.
-
Applies to mandatory, spontaneous, or pressure support ventilation modes.
-
Calculated from the total expired flow.
-
The VTE display updates at the beginning of the next inspiratory phase (immediately after exhalation ends).
3. Paw AV (Average Airway Pressure, in cmH₂O)
-
Represents the average airway pressure over the last 60 seconds.
-
Continuously monitored across all modes.
-
The value is updated every 15 seconds.
4. Paw Peak (Peak Airway Pressure, in cmH₂O)
-
Indicates the maximum pressure during the inspiratory phase.
-
Displayed for mandatory inspiration phases in ACV, SIMV, B-level, and CPR modes, as well as for spontaneous inspiration in CPAP mode.
-
Updated at the end of each inspiratory phase.
5. Rate (Breaths Per Minute, BPM)
-
Displays the number of breaths delivered or initiated in one minute.
-
Calculated using the time between two consecutive breaths (Rate = 60 ÷ breath interval in seconds).
-
Updated after each breath, and reflects both spontaneous and mandatory breathing.
Summary
The live monitoring section provides immediate, accurate feedback on the patient’s ventilatory status, enabling timely clinical decisions. Values update automatically based on real-time measurements and give insight into both spontaneous and controlled ventilation performance.
