Pressure Control and Pressure Support breaths do not compensate for PEEP. Delivered pressure is
controlled by the Pressure Control setting and is not affected by the PEEP setting. i.e.; A Pressure Control
setting of 20cmH O and a PEEP setting of 10cmH

EFINITION
A feature allowing ventilator parameters to be "preset" for an infant,
pediatric, or an adult patient.
A machine or assist breath where the circuit pressure is elevated to a
user-set pressure for a user-set period of time. Pressure Control
Breaths have an optional flow termination criteria.
A patient breath where the circuit pressure is elevated to a user-set
pressure and maintained there until flow decreases to a user-set
percentage of the peak flow achieved. Pressure Support Breaths
may also be terminated by a user-set maximum time, or by exceeding 2
breath periods.
A patient effort in which the proximal airway pressure dropped to, or
below the set Sensitivity setting. A pressure trigger will result in delivery
of an Assist or Patient breath, according to the ventilation mode.
Pounds per Square Inch Gauge. A unit for measuring pressure. 1 PSIG
= 0.7 bar.
Revolutions per minute. A unit for measuring turbine speed.
Allows the user to display the monitored values statically or
automatically scroll them. While scrolling is active, each monitored
value will be displayed for 3 seconds then the next value will be
automatically displayed.
Synchronized Intermittent Mandatory Ventilation.
A mode of ventilation where a minimum number of Machine or Assist
breaths are given, and the patient is allowed to trigger additional Patient
breaths. Available Breath types are Volume Control, Pressure Control,
Pressure Support, and Spontaneous.
A breath which the patient starts and cycles. Spontaneous breaths are
cycled at 10% of peak flow, set variable time termination, or when they
exceed 2 breath periods.
A ventilation mode used to temporarily minimize ventilatory support and
perform clinical assessments of a patient's dependence on, or ability to
be removed from positive pressure ventilation.
The exhaled volume measured at the patient wye. Exhaled Volume is
measured for all breath types.
The quantity of breaths given per minute; includes all breath types.
An electromechanical device used to measure pressure or flow.
A monitor that displays the calculated peak flow for Volume Control
breaths. Vcalc is calculated based on the set Tidal Volume and the Set
Inspiratory Time.
See Minute Volume, monitored.
O results in a maximum delivered pressure of 20cmH
