B Modes of Ventilation
B.1 Modes of Ventilation
This chapter is a general description of the various modes of ventilation and breath types available with the
Device name.
B.1.1 Assist/Control (A/C) Modes
When set to an Assist/Control mode, machine-initiated breaths are delivered at a clinician-set volume or pres-
sure, inspiratory time, and rate. If the patient triggers a spontaneous breath between machine breaths, the
ventilator will deliver a breath based on the volume or pressure settings and inspiratory time.
Whether initiated by the patient or the ventilator, all breaths are delivered at the same preset volume or pres-
sure and inspiratory time.
The names of the Assist/Control modes are:
• V A/C, if the breaths are based on a volume setting
• P A/C, if the breaths are based on a pressure setting
B.1.2 SIMV Modes
When set to a SIMV (Synchronised Intermittent Mandatory Ventilation) Mode, machine-initiated breaths are
delivered at a clinician-set volume or pressure, inspiratory time, and rate. These mandatory breaths are syn-
chronised with patient effort. If the patient triggers a spontaneous breath between machine breaths, the ven-
tilator will deliver a spontaneous breath, which is pressure-supported.
CPAP spontaneous breaths are not available in SIMV modes.
The names of the SIMV modes are:
• V SIMV, if mandatory breaths are based on a volume setting
• P SIMV, if mandatory breaths are based on a pressure setting
B.1.3 CPAP Mode
In CPAP, the ventilator maintains a constant level of pressure in the patient’s airway.
Note:
The default ventilation mode setting is P A/C; for more information, see below.
