Ventilator accuracy data
The following accuracy data is based on patient conditions and
settings described in ISO 80601-2-13. For the following to be true,
the ventilator is operating with 100 percent oxygen in the breathing
system and is connected to an integrated airway module.
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
Paw monitory accuracy Greater of +/- 5% or +/- 2.4 cmH2O
Breath rate accuracy +/- 1 bpm
I:E accuracy +/- 0.5 I:E
Note: If the ventilator is operating at a temperature, pressure, and/or gas composition that differs from when it was
calibrated, accuracy will decrease.
If the system is used without an integrated airway module, the
ventilator accuracy test requires the use of a properly calibrated O2
cell, 100 percent oxygen mixed gas, and one anesthetic agent in the
listed concentration: 3.4% Des, 3.1% Enf, 2.9% Hal, 3.1% Iso, or
2.8% Sev.
