Ventilator accuracy data
The following accuracy data are 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. Errors
may occur as described in the gas composition chart.
The minimum detectable breath size is 5.0 ml.
Expected cell life Four months of shelf life (23°C room
air) and one year of normal operation.
Delivery accuracy
Volume control mode Greater than 210 ml tidal volume -
accuracy of ±7% of set TV
60 to 210 ml tidal volume - accuracy of
±15 ml
Less than 60 ml tidal volume -
accuracy of ±10 ml
Pressure mode Inspiratory pressure - accuracy of ±3.0
cmH2O or 10% of delivered pressure
PEEP - accuracy of ±1.5 cmH2O
Monitoring accuracy
Volume control Greater than 210 ml tidal volume -
accuracy of ±9% of TV
60 to 210 ml tidal volume - accuracy of
±18 ml
Less than 60 ml tidal volume -
accuracy of ±10 ml
Pressure mode Accuracy of ±2.0 cmH2O or ±5% of
reading whichever is greater.
Note: Gas composition errors may be in addition 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.
Oxygen monitor accuracy
• When subjected to gas mixtures containing the following concentrations of
gases, the oxygen monitor has been tested to be within ±5% of the actual
gas concentration.
• Gas mixtures other than the ones listed below may result in an accuracy of
the oxygen monitor outside of the ±5% V/V.
Gas: At concentration:
Helium 50%
Carbon dioxide 5%
Nitrous oxide 80%
Halothane 4%
Enflurane 5%
Isoflurane 5%
Sevoflurane 5%
Desflurane 15%
