Ventilator accuracy data
The following accuracy data is based on patient conditions and
settings described in ASTM F1101. The ventilator is assumed to be
operating in volume mode. For the following to be true, the ventilator
is operating with 100 percent oxygen in the breathing system, or it is
connected to an anesthesia gas analyzer. If the ventilator is
operating without being connected to an anesthesia gas analyzer, or
at a temperature that differs from when it was calibrated, additional
errors may occur.
The minimum detectable breath size is 5.0 ml.

Delivery accuracy
Volume delivery accuracy Greater than 210 ml tidal volume - accuracy better than 7%.
Less than or equal to 210 ml but greater than or equal to 60 ml tidal
volume - accuracy better than 15 ml.
Less than 60 ml tidal volume - accuracy better than 10 ml.
Volume monitoring accuracy Greater than 210 ml tidal volume - accuracy better than 9%.
Less than or equal to 210 ml but greater than or equal to 60 ml tidal
volume - accuracy better than 18 ml.
Less than 60 ml tidal volume - accuracy better than 10 ml.
Inspiratory pressure delivery accuracy Greater of +/- 10% or +/- 3 cmH2O
PEEP delivery accuracy +/- 1.5 cmH2O
Pressure monitoring accuracy Greater of +/- 5% or +/- 2 cmH2O
Note: Gas composition errors may be in additions to the above normalized accuracy. When adding errors, positive
errors can have the effect of nulling out negative errors.
Note: Use of anesthetic agent could affect the errors by approximately -0.95%/% volume agent in normal mode.
Note: Temperatures greater than or less than 24°C may decrease BTPS accuracy.
