PIP xxx cmH2O
The Peak Inspiratory Pressure (PIP) monitor displays the greatest pressure measured during the
inspiratory phase and the first 300 ms of exhalation
36
.
Monitored PIP data is measured and displayed at the completion of inspiration.
MAP xx cmH2O
The Mean Airway Pressure (MAP) monitor displays a running average of the airway pressure for the
last 60 seconds. MAP data is recalculated and displayed in 10 second intervals.
PEEP xx cmH2O
The Positive End Expiratory Pressure (PEEP) monitor displays the pressure in the patient circuit at
the completion of exhalation. PEEP data is displayed at the completion of exhalation.
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
f xxx bpm
The Total Breath Rate displays the breaths per minute based on the last 8 breaths, and includes all
breath types. Total Breath Rate is recalculated and updated at the end of each exhalation or every 20
seconds.

This is done to protect the patient, since often the highest pressure is obtained at the beginning of the
exhalation phase.
