V*Home Measurements
Airway Pressure Measurements
A transducer inside V*Home takes pressure measurements to help assure the accuracy of delivered breath pressure,
including PEEP. V*Home also contains a second, redundant transducer to ensure accurate, reliable measurements.
The pressure measurements taken by transducers inside V*Home are then combined with measurements taken while
running the Pre-Use Test (to determine the resistance, compliance, and leak of the Ventec One-Circuit). Using these two
measurements, V*Home calculates the airway pressure at the patient interface (mask, tracheal tube, or mouthpiece).
To ensure the set PEEP is maintained when using a passive or valveless circuit, V*Home calculates and delivers the ow
required to reach and maintain the set PEEP.
In addition, Ventec Life Systems recommends the use of appropriate alarms to ensure the accuracy of delivered breath
pressure. For example, the High Pressure and Low Inspiratory Pressure alarms, as well as the Low Minute Volume alarm
can be set to ensure breaths are accurately delivered during pressure-control ventilation.
NOTE: If the High Pressure and Low Inspiratory Pressure alarms, and/or Low Minute Volume alarms are not set to detect
problems with Ventilation therapy, ensure the rest of your alarm suite is congured appropriately to detect any problems
with the delivered ventilation.
Flow Measurements
When using a passive or valveless Ventec One-Circuit or mouthpiece patient circuit, V*Home calculates ows using
measurements from its internal transducers and the Pre-Use Test.
Volume Measurements
Exhaled volumes are calculated using measurements from transducers inside V*Home, and measurements from the Pre-
Use Test.
FiO2 Measurements
V*Home includes an integrated FiO2 monitor, which takes measurements as gas travels to the Ventec One-Circuit
connection port.
The Calculated FiO2 monitor calculates the estimated FiO2 delivered to the patient, based on V*Home settings and
the patient’s breathing patterns. The calculation will change as breathing patterns change, or when V*Home Ventilation
settings are modied.
