HANGE THE
HMEF
AutoMedx recommends placing the HMEF between the exhalation control valve and
the patient connection port. See Figure 14 on page 22. AutoMedx recommends using
the procedure outlined below when the HME filter needs to be changed while the
patient requires PEEP. This procedure is intended to limit the amount of PEEP lost by
the patient when the HME filter needs to be added, exchanged, or removed.
1)
Unwrap the new HME filter
2)
Reduce the RESPIRATORY RATE on the SAVe II+ to 0 and CONFIRM. The
heart rate icon will begin to blink.
3)
Close off the patient airway using your current protocols.
4)
Disconnect the HME filter from the patient circuit (between the control valve and
the flex segment that connects to airway).
5)
Connect the new HME filter in place slowly. Connecting quickly may trigger a
HIGH PEEP alarm. If the HIGH PEEP alarm triggers while connecting the HME:
a. Disconnect one end of the HME.
b. Press the MANUAL TRIGGER button on the SAVe II+ (This will trigger a
disconnect alarm. Ignore this alarm for the time being).
c. Reconnect the HME to the breathing circuit less abruptly.
d. Repeat as needed so that the HIGH PEEP alarm is not flashing - solidly
illuminated is permissible.
6)
If the HIGH PEEP alarm is not flashing, open the patient airway per your
healthcare center protocol.
7)
Administer one manual breath to provide immediate respiration.
8)
Set the desired RESPIRATORY RATE on the SAVe II+ and CONFIRM, the
SAVe II+ should begin administering breaths at the set rate and volume.
9)
Verify the patient is being correctly ventilated.
To display the last measured values for the PIP and PEEP press the CONFIRM button
when no setting changes are pending.
If the patient airway remains blocked, the "PIP Reached" alarm will indicate when
breaths are administered, and the PEEP algorithm will reset. The PEEP will slowly rise
from 0 cmH
2
O to the set value when normal operation resumes. This happens over
22 to 24 breaths.
If a breath is delivered (manually or automatically) while the HIGH PEEP alarm is active
(flashing) the PEEP algorithm may reset, slowly raising the PEEP from 0 cmH
2
O to the
set value once the disconnect alarm has been cleared.
This procedure could also be used to exchange the entire patient circuit as needed
while minimizing the PEEP lost by the patient.
