Action To Be Taken If Patient Vomits During Resuscitation; Demand Breathing And Automatic Circuit Shut O - O-Two CAREvent CA User Manual

The use of gas pressure regulators that do not maintain
a minimum output pressure and fl owrate in line with the
requirements of the specifi cation may cause the device to fail
3.4. Action to be taken if patient
vomits during resuscitation
Should the patient vomit into the mask during resuscitation the
following steps should be followed to clear the foreign material:
1. Remove the mask from the patient's face and clear any foreign
material from the patients airway. Depress the manual button
or allow the resuscitator to cycle automatically for a few
breaths to clear the mask and valve of foreign material.
2. If depressing the manual button repeatedly or automatically
cycling the resuscitator does not clear the foreign material
from the patient valve,turn the selector to the OFF position,
remove the facemask and unscrew patient valve swivel
housing (e) from the resuscitator body being careful to ensure
that the diaphragm is retained (Fig.3).
3. Shake out any foreign material from the resuscitator,
diaphragm, face mask and patient valve swivel housing.
4. Reassemble the facemask, patient valve and diaphragm and
attach to the resuscitator.
Note: When using the single use patient valve, vomitus may be
forced past the diaphragm and contaminate the bio-fi lter. This
may necessitate the use of a new single use valve.

3.5. Demand Breathing and Automatic Circuit Shut O

Should the patient commence spotaneous breathing at a fl owrate
of greater than 30 lpm for more than 1 second the CAREvent®
CA will sense the patient's inspiratory e ort and will stop cycling
automatically allowing the patient to "Demand Breathe" at their
own rate and volume on 100% oxygen (if connected to an oxygen
supply). If they cease spontaneous breathing the ventilator
will recommense automatic cycling after 5 - 8 seconds delay
(depending on the depth of the patients previous respiration)
without intervention by the rescuer.
