Monitor Resolution and Accuracy
NOTE: When used with passive, or valveless Ventec One‑Circuits, V*Home was designed for use with a humidier or
HME. All volumes and ows are expressed in BTPS unless stated otherwise.
NOTE: Monitors incorporating pressure measurements are calculated using a pressure sensor inside V*Home, which
calculates the pressure at the Ventec One-Circuit connection port.
NOTE: Unless otherwise stated, monitor accuracy specications are met when V*Home is used as recommended by
Ventec Life Systems.
Monitor Resolution Accuracy
Airway pressure
manometer
N/A ±(1.4 cmH2O + 8% of actual) up to 15 cmH2O
±(2 cmH2O + 4% of actual) above 15 cmH2O
Breath Rate 1 BPM ±10% BPM
Date 1 day N/A
FiO2 1% ±(2.5% + 2.5% of actual)
NOTE: Air contaminants and pollutants (including methane) may have an adverse
effect on the accuracy and long‑term performance of the FiO2 monitor.
I:E Ratio 0.1 Calculated from the average monitored inspiratory time and average monitored
exhalation time accuracies of ±50 ms or 5%, whichever is greater
