Respiratory Volume Monitoring; Respiratory Volume Monitoring Window - Dräger Fabius OS Instructions For Use Manual

Respiratory Volume Monitoring

Respiratory volume is measured using thermal
anemometry. The flow sensor output is converted
into meaningful readings for minute volume, tidal
volume, and respiratory rate displays.
CAUTION
The functioning of the respiratory volume monitor
may be adversely affected by the operation of
electrosurgical equipment or short wave or micro-
wave diathermy equipment in the vicinity.
NOTE:
Sudden, irregular expiratory flow may cause
erratic tidal volume and respiratory rate displays.
To avoid such erroneous measurements, defer
reading the display until a full minute has elapsed
after the irregular flow has stopped.

Respiratory Volume Monitoring Window

The respiratory volume monitoring window shows
the following information:
1 Frequency (Freq) shows the number of breaths
during the previous minute of respiration in units
of Breaths Per Minute (bpm) (1/min).
Readings appear after two breaths.
The display range is from 2 bpm (1/min) to
99 bpm (1/min).
2 Tidal Volume Measurement (V
expired volume for each breath in units of milli-
liters (mL).
The display range is from 0 mL to 1400 mL.
3 Minute Volume Measurement (MV) conti-
nuously displays the volume of exhaled gas
accumulated during the previous minute of
respiration in units of liters/minute (L/min).
The display range is from 0.0 L/min to
99.9 L/min.
