21-2 DELTA/DELTA XL/KAPPA VF8
21 R
ESPIRATORY MECHANICS
Overview
When connected to an optional etCO
2
/Respiratory Mechanics pod, the monitor can
calculate and display CO
2
, airway pressure, flow and volume waveforms. You can
also configure the monitor to display numerical readings of etCO
2
, and additional
derived respiratory parameters.
Respiratory mechanics parameters are trended in graphical and tabular form. For more
information about trend display, see 6, Trends.
The monitor collects information about airway pressure, flow, volume and associated
variables via a specially designed airway adapter attached to the patient’s endotracheal
tube. Depending on the adapter in use, the pod obtains readings for the following:
End-tidal CO
2
(etCO
2
)
Respiratory mechanics
Both etCO
2
and respiratory mechanics
Precautions
Refer to the general precautions section for etCO
2
(see page 19-3).
NOTE:
This chapter deals exclusively with respiratory mechanics monitoring. For
information about monitoring etCO
2
, see chapter 19.
You cannot conduct sidestream measurements of etCO
2
using the etCO
2
/
Respiratory Mechanics pod.
WARNING: The internal transducer is connected by the
sampling tube to the breathing circuit. The breathing circuit
can not be completely disinfected between uses of
successive patients because the internal transducer cannot
be completely disinfected. Compliance with certain
recommendations of the American Thoracic Society regarding
hygiene and infection control during spirometry may not be
practical using the etCO
2
/Respiratory Mechanics pod.
