(d) Terms and Definitions
Airway Resistance:
Pressure drop across airway per unit flow.
CPAP:
Constant Positive Airway Pressure. The ventilator maintains a set constant
positive pressure in the breathing circuit throughout the ventilation cycle
when the patient is breathing spontaneously.
CMV:
Controlled Mandatory Ventilation.
Expiratory Phase:
Interval from the start of expiratory flow to the start of inspiratory flow.
Expiratory Time (T
E
):
Duration of the expiratory phase.
FiO
2
:
The oxygen content of the gases inspired by the patient expressed as a
fraction.
Frequency (f):
The number of ventilation cycles per minute (breaths/min).
HME:
Heat and Moisture Exchanger.
IMV:
Intermittent Mandatory Ventilation. The ventilator delivers the set breaths to
the patient intermittently. The patient breathes spontaneously between
ventilator breaths.
Inspiratory Flow:
The flow passing to the patient during the inspiratory phase. This flow will
always be less than the flow through the breathing circuit and will be
determined by the patient’s airway resistance and lung compliance and by the
set inspiratory pressure.
Inspiratory Phase:
Interval from the start of inspiratory flow to the start of expiratory flow.
Inspiratory Time (T
I
):
Duration of the inspiratory phase.
I/E Ratio:
The ratio of the Inspiratory Time to the Expiratory Time.
Lung Compliance:
Volume added per unit pressure increase when is added to a human or
artificial lung.
Muting:
Causing the cessation of a sounding auditory alarm by the deliberate action of
a second depression of the silencing button. The muting is reset when either
the condition which caused the alarm is removed or the ventilator is switched
off.
MRI:
Magnetic Resonance Imaging.
Mouth (Proximal)
Pressure:
The patient inflation pressure as measured at the patient's mouth. With a
pressure generator ventilator such as the babyPAC this pressure will normally
be equal to the set inspiratory pressure.
PEEP:
Positive End Expiratory Pressure. Pressure in the breathing circuit is
maintained at a positive pressure throughout the expiratory phase.
ACTIVE PEEP:
Function in which the PEEP is maintained by a ventilator flow during the
expiratory phase instead of depending on the passive expiratory flow from the
patient (passive PEEP).
Pressure Generator:
The ventilator delivers ventilation by establishing a constant set pressure at the
patient connection throughout the inspiratory phase. The resultant flow into
the lungs is determined by the compliance of the patient’s lungs and the
resistance of the airways.
Silencing:
Causing the temporary cessation of an auditory alarm by the action of
depressing the silencing button.
Tidal Volume
(V
TDEL
):
Volume of gas delivered to the patient during an inspiration phase.
VBS:
Ventilator Breathing System.
