DEFINITION
A patient breath where the circuit pressure is raised to an operator-set
pressure and maintained until flow decreases to an operator-set
percentage of the peak flow achieved. Pressure Support Breaths may
also be terminated by an operator-set maximum time, or by exceeding
2 breath periods.
A patient effort in which the pressure below PEEP is less than the
Sensitivity setting. A pressure trigger will result in a delivered breath.
Pounds per Square Inch Gauge. A unit for measuring pressure.
Revolutions per minute. Turbine speed is measured in rpm.
Displays the monitored values statically or allows for automatic
scrolling. 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 ventilation mode 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
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 quantified at the patient wye. Exhaled volume is
measured for all breath types.
The quantity of breaths given per minute; includes all breath types.
A measuring device. Transducers can be used to quantify flow or
pressure.
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.
A machine or assist breath where a operator-set volume is delivered
over a operator-set time. Flow is delivered in a decelerating waveform
where the peak and final flows are calculated so that the final flow is
50% of the peak flow.
See tidal volume, monitored.
