TERM DEFINITION
LED
Light Emitting Diode. An indicator that is illuminated on the Front Panel.
Lpm
Liters Per Minute. A unit of measure for flow.
Machine Breath
A volume or pressure breath that is initiated by the operator or the
ventilator, and is controlled and cycled by the ventilator. Machine
Breaths may occur in Control and Assist / Control modes. The operator
may cause a machine breath in any mode using the Manual Breath
button.
Manual Breath
A Machine Breath initiated by the operator pressing the Manual Breath
button.
MAP
See Mean Airway Pressure.
Mean Airway Pressure,
monitored ( MAP )
Mean Airway Pressure. MAP is calculated for the most recent 60
seconds and is updated every 10 seconds.
Minimum Exhalation
Time
The minimum time required for exhalation is 346 msec. Control settings
are limited to ensure the Minimum Exhalation Time is provided. Breaths
may not be triggered during the Minimum Exhalation Time.
Minimum Inspiratory
Time
The minimum time required for inspiration is 300 msec. Control settings
are limited to ensure the Minimum Inspiratory Time is provided.
Minute Volume,
monitored ( VE )
The average volume delivered to the patient for the last 60 seconds. VE
is updated at the end of each breath and is calculated based on the last
8 breaths. All breath types are included.
msec
One one-thousandth of a second.
Nm
Newton meters. A measurement of torque equivalent to 0.007062 inch
ounces.
Non Volatile Memory
Memory that is retained when ventilator is in Standby mode or powered
off.
O
2
Oxygen.
Patient Breath
A Pressure Support or Spontaneous breath that is initiated by the
patient, controlled by the ventilator and terminated by the patient.
Patient breaths may occur in SIMV and CPAP ventilation modes.
Patient Effort
Any inspiratory effort by the patient.
Peak Inspiratory
Pressure, monitored
( PIP )
The maximum circuit pressure occurring during the inspiration and first
300 ms exhalation phase of a breath. PIP is measured at the patient
wye.
PEEP
See Positive End Expiratory Pressure.
PIP
See Peak Inspiratory Pressure.
Positive End Expiratory
Pressure, monitored
( PEEP )
The circuit pressure measured at the end of the exhalation.
POST
Power On Self Tests. A set of self-tests the ventilator performs when
turned on to verify the operational integrity of the Processor, Displays,
Audible Alarm, Confirming Audible Chirp, SRAM, Program Memory and
EEPROM (some tests require operator visual and/or audible
verification).
