Operating the Ventilator
5-10 Operator's Manual
Occlusion alarm/Sustained
Occlusion alarm
The patient will not be
ventilated. Manually ventilate
the patient until this is
resolved.
The patient’s expiratory gas
pathway is occluded or partially
occluded. Evaluate everything in the patient’s pathway of
exhalation to determine what is causing resistance and
resolve the issue.
Change HME, expiratory filter, or both, if used.
Change the exhalation valve.
Unkink expiratory drive line.
Replace flow sensor.
Apnea alarm No mandatory breaths or
spontaneous efforts detected
within the set time period of 5–70
seconds. Determine if patient is breathing.
Make sure Ptrig/Flow trig setting is set sensitive (low)
enough.
Use A/CMV or SIMV (not SPONT), and make sure respi-
ratory rate setting is adequate.
High (Peak) Pressure alarm
This alarm violation stops
breath delivery until pressure
drops.
Coughing/need for airway care or
bronchodilator treatment. Perform suctioning/airway care, or if due and prescribed,
give prescribed bronchodilator treatment.
Secretions too dry due to
inadequate humidity. Use heated humidifier with the appropriate
temperature setting and keep tubing warm.
Pneumatic nebulizer inline. Contact Covidien Technical Services for assistance.
Reference
Contact Information on page 1-9 .
Supplemental oxygen flowing
directly into breathing circuit. Use the low flow oxygen reservoir or 50 psi air oxygen
mixer.
Kinked tubing. Unkink the tubing.
Sticky exhalation valve or on-
airway flow sensor from
medication treatments or
secretions. Install a clean exhalation valve, an on-airway flow sensor,
or both.
Ventilation settings mismatch the
patient condition, such as an
actively spontaneously breathing
patient under controlled
ventilation mode, ventilator’s
inspiratory time (i-time) setting too
long, flow setting too high, VT
setting too high. Evaluate patient and change settings (ventilation mode,
flow, VT, i-time, flow waveform) as appropriate.
Alarm setting too low. Resolve appropriately.
