EFINITION
Alternating Current.
The airway tubing that connects the ventilator and the patient.
The airway pressure measured at the exhalation valve.
A bar graph type display composed of 60 LEDs. This display shows the
real-time airway circuit pressure from –10 cmH
An audible and visual notification that an alarm condition has been met.
Audible notification includes an oscillating or continuous tone. Visual
notification may include flashing displays, illuminated LEDs, and text
messages shown in the display window.
Apnea occurs when the time between breath starts exceeds the set
apnea interval.
Apnea Backup Ventilation begins when an apnea alarm occurs and
continues until the patient initiates 2 consecutive breaths or the alarm is
canceled by an operator. Apnea Backup Ventilation is given in the
Assist / Control mode.
The maximum period of time allowed between breath starts. If the time
between breath starts exceeds this interval, an Apnea alarm occurs.
A mode of ventilation where the patient receives a minimum number of
machine and assist breaths. The available breath types are Volume
Control and Pressure Control.
A volume or pressure breath that is initiated by the patient, and
controlled and cycled by the ventilator. Assist breaths may occur in
Assist / Control and SIMV modes.
Actual Temperature and Pressure.
The process of determining the transducer zero offset for ambient
pressure.
A continuous flow of gas through the airway circuit during the
exhalation phase of the breath.
Breaths Per Minute.
The length of time between machine initiated breaths. The Breath
Period is determined by the Breath Rate setting. For example, a Breath
Rate of 6 would give a Breath Period of 10 seconds (60 seconds / 6
bpm).
The number of breaths given in a minute, including machine, assist,
and patient breaths.
The minimum number of machine breaths given in a minute.
Body Temperature, Pressure Dry.
