3.2. Manual Ventilation and Cardiac Compressions.

The CAREvent® CA Handheld Resuscitator has a Manually Actuated,
Automatic Ventilation Override Button (Manual Button) with a 20
second delay to automatic cycling re-start to assist in the timing
of ventilations in conjunction with external cardiac compressions.
By using the Manual Button, the operation of the ventilator can
be easily timed with the chest compressions so as to avoid the
potential problem of the aspiration of stomach contents due to
gastric distension which may occur if overlap of chest compression
and infl ation occurs. (It has been shown in some studies that,
in patients that are intubated, this overlap of compression and
infl ation may increase cardiac output without the danger of
gastric distension.) The fl owrate provided is equivalent to the
preset automatic fl owrate.
1. If no respiratory e ort is observed, position yourself above the
patient's head. Turn on the gas supply.
2. Allow the device to cycle once and then apply the face mask
over the patients mouth and nose.The thumb and index fi ngers
are used to hold the mask to the face while the remaining
three fi ngers of each hand are placed along the angle of the
jaw. A tilt action is used to hyperextend the neck and move
the jaw forward. This helps displace the tongue away from the
back of the throat and maintains an open airway.
3. If manual Ventilation is to be used depress the manual button
and observe the rise of the patient's chest. Release the button
when chest rise is adequate.
