Hamilton G5 - Hold Window

7-16 624074/07
7 Monitoring
NOTE:
• To terminate a pending hold,
Close the window.
You can terminate an active hold by pressing the
knob during the hold cycle.
• To display the entire hold maneuver, wait to start the
maneuver until the first inspiration is shown to the
far left of the curve display.
The inspiratory and expiratory hold maneuvers let you stop the
ventilator’s breathing cycle at the end of inspiration or exhala-
tion, for a maximum of 10 s (adult and pediatric patients) or 3
s (infant patients). The primary application of the breath hold is
to measure lung mechanics by the occlusion technique.
To perform a hold maneuver:
1. Open the
Tools -> Hold window (Figure 7-11).
2. Select
Insp hold or Exp hold to perform an inspiratory
or expiratory hold maneuver. When the pressure waveform
flattens, deactivate the hold maneuver by selecting
Insp
hold or Exp hold again. After the maneuver, the Hold
window closes, and the freeze function is activated auto-
matically.
