Calibration and other
constants Number of motor quadcounts between
home and end positions Must be input when new piston/cylinder
installed.
Calibration and other
constants Oxygen mixing constants, including flows
from orifices and regulator pressures Must be input when new oxygen
regulator assembly installed.
Calibration and other
constants PEEP pump calibration lookup table Source: PEEP pump calibration. Lookup
table updated during EST and calibration
verified.
Calibration and other
constants Current of PEEP pump at 0% duty cycle Value in counts. Currently unused.
Calibration and other
constants Oxygen regulator pressure transducer
calibration data Source: oxygen regulator pressure
transducer calibration. Checked during
EST.
Calibration and other
constants Oxygen sensor (FIO
2
) calibration data Calibration verified during FIO
2
calibration check.
Calibration and other
constants Pressure solenoid calibration constraints Updated when new pressure solenoid
board is installed and during calibration.

Ventilator configuration Ventilator breathing circuit resistance
and compliance Source: SST/EST (circuit resistance field
currently unused).
Ventilator configuration Endotracheal tube size, in mm Source: SST/EST
Ventilator configuration Ventilator breathing circuit type Source: SST/EST
Ventilator configuration Model
Ventilator configuration Humidification device type Source: SST/EST
Ventilator configuration Circuit characteristic change Indicates whether there has been a
change to the circuit type, humidification
device, or ET tube size, used to determine
whether circuit compliance test must be
run before skipping to the end of SST or
EST.
