Manual Breath
Manual Breath delivers a single breath at the set tidal volume or pressure. In
CPAP/PSV ventilation mode, where there is no definition for machine breath, the
Manual Breath is set according to the default volume control for the specified
patient weight chosen at startup.
Hold
Hold activates and/or cancels the hold maneuver. Press the button once to
initiate an inspiratory hold maneuver, which allows the calculation of static
compliance. Press it twice to initiate an end to the expiratory hold maneuver,
which allows the calculation of intrinsic PEEP. For more details see page 235.
Clear
Clear has several functions. Press it to perform the following:
ï‚· Clear the screen of its current selection and return the operator to the
previous screen or menu selection – just like the Escape key on a computer
keyboard.
ï‚· Minimize any red alarm-warning pop-up window and mute the alarm sound
for 30 seconds. If clear is pressed again within 30 seconds, an alarm warning
pop-up window appears.
ï‚· When Clear is pressed and held, all corrected alarm messages (displayed in
green) are cleared.
