|
Alarm event |
Any condition or occurrence on a ventilator that requires the clinicians awareness or action |
|
|
Closed-loop control |
Means of mechanical system control in which information about output is used to modify input, which in turn Improve the output |
|
|
Control circuit |
Drive mechanism in a ventilator that transmits or transforms energy in a predetermined manner to assist or replace the patient's muscle in performing the work of breathing |
|
|
Control variable |
Factors that determine what controls breath delivery from a ventilator, such as pressure, volume, flow and sometimes inspiration and expiration time |
|
|
Cycle time |
Ventilatory period; the reciprocal of ventilatory frequency (that is, 60 seconds per minute divided by the number of breaths per minute) |
|
|
Cycle |
In respiration, an inspiration followed by an expiration; period of time between the beginning of one breath in the beginning of the next |
|
|
Expiratory flow time |
Interval from the start of expiratory flow to the end expiratory flow |
|
|
Expiratory pause time |
Interval from the end of expiratory flow to the start of inspiratory flow, used to measure auto- PEEP |
|
|
Expiratory phase |
Restoration period during which all mechanics from the start of expiratory flow to the end of expiratory flow occur, including those associated with expiratory hold or pause, until the start of inspiratory flow |
|
|
Expiratory time |
Time interval from the start of expiratory flow to the start of inspiratory flow; components include expiratory flow time and expiratory pause time |
|
|
Inspiratory flow time |
Interval from start of inspiratory flow to the end of inspiratory flow |
|
|
Inspiratory pause time |
Interval from the end of inspiratory flow to the start of expiratory flow |
|
|
Inspiratory phase |
Respiration phase during mechanical ventilation in which pressure, volume and flow increase above their end expiratory values: quantified by specifying the inspiratory time, defined as the time interval from start of inspiratory flow to the start of expiratory flow including the hold or pause time |
|
|
Inspiratory time |
Time interval from the start of inspiratory slow to the start of expiratory flow, including the inspiratory a hold or pause time. |
|
|
Mandatory breath |
Inspiration that is machine triggered or machine cycle or both |
|
|
Mode of ventilation |
A combination of control phase in conditional variables that establishes a set pattern of spontaneous breaths, mandatory breaths or both. |
