3.2.9 Manual/ Hold
During exhalation phase, if Manual/ Hold button (E) in Figure 1 is pressed, a
mandatory breath will be initiated and either the flow rate or set pressure
control parameter will be delivered as long as the Manual/ Hold button is
pressed or until I-time setting is achieved.
After I-time if the button still pressed, the ventilator will switch to
inspiratory hold function in which the ventilator will cut the flow but will
keep the exhalation port closed in order to block exhaled gas from going to
ambient resulting in the maintenance of lung pressure.
The maximum inspiratory hold time is 6 seconds. After that time, the
ventilator will switch to exhalation phase by opening airway pressure to
ambient.
Note
Manual/ Inspiratory Hold function exists only in SIMV mode.
