Alarm Status Messages
f PEEP OFF
The f PEEP OFF message is displayed when;
• The High Breath Rate alarm is turned off by being set to HIGH f OFF and
,
• The High PEEP alarm is turned off by being set to HI PEEP OFF.
This is an informational message only. The message is displayed at power up, when monitored data
is being scrolled automatically, and when no front panel activity is detected for 60 seconds.
To clear the f PEEP OFF message:
1) Push any front panel button or turn the Set Value knob.
HI PEEP OFF
The HI PEEP OFF message is displayed when;
• The High PEEP alarm is turned off by being set to HI PEEP OFF and
,
• The High Breath Rate alarm (HIGH f) is turned on.
This is an informational message only. The message is displayed at power up, when monitored data
is being scrolled automatically, and when no front panel activity is detected for 60 seconds.
To clear the HI PEEP OFF message:
1) Push any front panel button or turn the Set Value knob.
WARNING
Accuracy of PEEP setting - Variations in the patient’s breathing pattern and/or leaks in the patient
circuit (including leaks around the tracheostomy tube cuff) can affect PEEP. PSI recommends that the
clinician set the PEEP to the prescribed level on a test lung while observing the PEEP value in the
LTV display window. The clinician should also periodically monitor the PEEP value in the LTV display
window. Using an inaccurate PEEP setting due to a patient leak can result in less than prescribed
PEEP or undesirable increases in patient circuit pressure when the patient circuit leak changes.
AVERTISSEMENT
Exactitude du paramètre PEP – Les écarts dans le mode de respiration du patient et/ou les fuites
du circuit du patient (y compris les fuites autour du ballonnet pour canule de trachéostomie) peuvent
affecter le PEP. Des études et investigations préliminaires recommandent que le clinicien définisse le
PEP au niveau prescrit sur un poumon d’essai tout en observant la valeur PEP de l’écran graphique
LTV. Le clinicien doit par ailleurs surveiller de façon périodique la valeur PEP de l’écran graphique
LTV. L’utilisation d’un paramètre PEP inapproprié en raison d’une fuite de patient peut
potentiellement résulter en un paramètre inférieur au paramètre PEP prescrit ou en une
augmentation indésirable de la pression du circuit du patient lorsque la fuite du circuit du patient
change
