nCPAP/IMV
Nasal CPAP (nCPAP) is a spontaneous ventilation. In this mode, no mechanical positive
pressure breaths deliver. Nasal IMV is a time triggered, time cycled mode of pressure
control ventilation provided via nasal prongs as an enhancement to the nCPAP mode.
When a rate is set greater than zero, time triggered, time cycled mandatory breaths
deliver. Each breath comprises an inspiratory phase, during which the delivered pressure
increases from baseline (PEEP) to PEEP + Inspiratory Pressure, and an expiratory phase,
during which the delivered pressure returns to PEEP.
Nasal IMV breaths are:
• Controlled by pressure
• Limited by pressure
• Cycled by time
Primary controls: nCPAP level, Inspiratory Pressure, Inspiratory Time, FiO

*No advanced settings appear when Rate is set to o.
nCPAP/IMV is only available in the neonatal patient size setting.
