Nasal Intermittent Mandatory Ventilation (nIMV)

Nasal CPAP is a spontaneous mode of ventilation. In this mode, no mechanical positive pressure breaths are delivered.
Nasal IMV is a time-triggered, time-cycled mode of pressure control ventilation provided via nasal prongs. This is an
enhancement to the nasal CPAP mode. When a rate is set greater than zero, time-triggered, time-cycled mandatory
breaths are delivered. Each breath comprises an inspiratory phase, during which the delivered pressure is increased
from baseline (PEEP) to PEEP + Inspiratory Pressure, and an expiratory phase, during which the delivered pressure is
returned to PEEP.
Nasal IMV breaths are:
Controlled by pressure
•
Limited by pressure
•
Cycled by time
•
Note:
Nasal CPAP/IMV is only available in the neonatal patient size setting.
Circuit compatibility
This mode utilizes standard two-limbed infant/neonatal patient circuits and nasal prongs for the patient interface.
The following nasal CPAP prongs have been approved for use:
