Appendix K: Glossary
Breath Interval
Elapsed time from the start of one breath to the start of
An operator set ventilator parameter.
Trigger
Value at which the ventilator initiates delivery of a breath
as a result of measured patient effort.
Body Temperature at Ambient Pressure, Saturated.
Ambient Temperature, Ambient Pressure, Dry.
Demand Flow
The flow generated by the ventilator to meet the patient’s
flow demand in order to maintain PEEP at the preset
Alternating Current (mains electricity).
Bias Flow
Flow through the patient breathing circuit during the
expiratory phase. This flow is used for flow triggering.
Breath Period
The length of time between machine-initiated breaths.
Depends on the Breath Rate setting.
The number of breaths delivered in a minute.
Body Temperature at Ambient Pressure, Dry
A push button switch used to toggle a function on or off.
2
Centimeters of water pressure.
Controls
Any button, switch, or knob that allows you to modify the
Event
The occurrence or activation of certain controls or
functions of the ventilator or a patient care activity, which
can be stored in the trend buffer.
Flow
The rate at which gas is delivered. Measured in liters per
minute (L/min).
A visual element showing operational status.
Liters. A unit of volume.
Liters per minute. A unit of flow.
Mode
An operating state of the ventilator that determines the
allowable breath types.
A measured value displayed in the monitor window.
2
Patient Breathing
Circuit
The tubing that provides the ventilatory interface between
the patient and ventilator.
Airway Pressure. Measured in cmH
2
PEEP
Positive End Expiratory Pressure. Pressure maintained in
the circuit at the end of exhalation.
Ppeak
Peak Inspiratory Pressure. Shows the highest circuit
pressure to occur during inspiration. The display is
updated at the end of inspiration. P
peak is not updated for
