| Tachypnea |
Breathing faster than normal. |
| TC |
Tube Compensation (See Automatic
Tube Compensation) |
| Time Constant |
The time in which an exponential
process is 63% complete. For a pneumatic system characterized
by a single compliance, C, and a single resistance, R,
the time constant is the product RxC. |
| Triangular Wave |
A wave profile that rises
in a straight line from its baseline to a peak value from
which it drops back to the baseline. |
| Trigger
Flow |
The change in breathing
circuit flow required to initiate the ventilator's inspiratory
phase. |
| Trigger
Pressure |
The change in breathing
circuit pressure required to initiate the ventilator's
inspiratory phase. |
| Trigger Response Time |
(See Inspiratory
Triggering Response Time.) |
| Trigger Volume |
(See Inspiratory
Triggering Volume.) |
| Tube Compensation |
(See Automatic
Tube Compensation) |
| TV |
Tidal Volume (Exhaled Tidal
Volume) - The change of volume of the lungs (estimated
by the gas volume entering or leaving the lungs) during
either the inspiratory or expiratory phase of a breath. |
