2.3.3 Available Measurement Parameters
Table 3. Parameters (parameter list changes depending on module attached)
Flow
Rate. “Q” is used on the
Graph Screen.
High pressure transducer
(4081 only)
Peak Flow Rate
—Peak Inhaled
Flow Rate. “Qpeak” is used on
the Graph Screen.
Absolute pressure in flow tube.
If flow tube open to
atmosphere, then this is also
the
barometric pressure
Minimum Flow Rate
—In Bi-
Directional Mode this is the
Negative of the Peak Exhaled
Flow Rate. “Qmin” is used on
the Graph Screen.
Oxygen concentration (with
both 4081 and 4073 only)
Inhaled tidal volume Temperature of gas (accurate
for flows above 5 L/min)
Exhaled tidal volume (4081
only) Frequency
—Breath rate
V
Real-time volume (graphing
only) Inspiratory time
Inhaled minute tidal volume Inspiratory pause time (4081
only)
Low pressure transducer
—
Airway pressure (4081 only)
Inspiratory time including the
pause time
Peak Inspiratory pressure (4081
only) Expiratory time
Peak End Expiratory Pressure

Mean Airway Pressure (4081
only) I to E ratio which includes
inspiratory pause time
Minimum low Pressure (4081
only) Time of day
Delta low pressure
—Delta
airway pressure (4081 only)
