Gas exchange
monitor match those on the calibration gas bottle. If they do not match, calibrate
airway gases.
●
When anesthetic agents are present, use the E-CAiOVX module for monitoring
airway flow, gas exchange, and metabolism.
Gas exchange measurement setup
Gas exchange equipment to patient connection
The equipment to patient connections for gas exchange are similar to those of Patient
Spirometry but there are also some connection-related issues to be noted. Only the
modules E-CAiOVX and E-COVX measure gas exchange.
Gas exchange patient connections with HME/HMEF/filter
NOTE
Always place the HME/HMEF/filter between the D-lite(+) sensor
and the patient.
NOTE
By-pass flow together with long expiration flow pause time
may disturb the measurement. Consider using shorter
expiration time to diminish the effect. In addition, you may use
a suitable spacer with a 5 to 10 ml dead space (e.g., a straight
T-adapter) between the Y-piece and D-lite(+)/Pedi-lite(+). The
by-pass flow effect may exist even in an adult setting, but it
is more emphasized when monitoring pediatric patients and
using the Pedi-lite(+).
