Operation
8.4.4 Pause mode
Prerequisite:
– The Pause operation mode is switched on in the system setup (see "Vertical tab
"General"", page 214).
In Pause mode, ventilation is stopped. With electronically controlled gas mixers,
gas delivery is also stopped. The breathing system is depressurized so that manual
ventilation is not possible.
This mode is useful for short-term interruptions to a therapy such as, e.g.,
intraoperative suctioning of mucus or relocation of the patient.
This mode is also useful during regional anesthesia. The patient’s respiration can
be monitored via the sample gas measurement without distracting ventilation
alarms being issued. The gas concentration measurement remains active and
waiting for respiratory phases. With the detection of respiratory phases, apnea
monitoring is automatically activated.
The device remains in this operation mode until the user switches to a different
ventilation mode. The timer defines the period of time after which an alarm is
issued. This alarm reminds the user to start the ventilation manually again.
Setting the timer to Off deactivates the alarm. In addition, the total elapsed time in
Pause operation mode is displayed.
To reduce contamination of the ambient air with anesthetic gases through an open
Y-piece, use this operation mode for, e.g., regional anesthesia or short breaks in
therapy such as disconnection or intubation.
8.4.4.1 Activating the pause
CAUTION
Danger due to hypoxic gas mixture
If the patient breathes spontaneously while in Pause operating mode, there is a risk
of inhalation of a hypoxic gas mixture.
► Monitor the patient’s breathing.
