HLM ventilation
Tuesday, February 15, 2011
During an open-heart surgery the
Heart-Lung Machine takes over the functions of the heart and lungs.
Hence the anaesthesia machine is disconnected from the patient and
the Heart-Lung Machine performs the perfusion.
In this time period the anaesthetist
can choose from different ventilation modes e.g. low flow
ventilation to avoid atelectasis, without the noice nuisance from
patient related audio alarms, which unintendenly disturbs the
surgeon and the operation staff.
Furthermore, the silent alarm
management gives the anaesthetist the possibility to preset the
ventilator settings and set the ventilator in Stand-By mode so that
the Siesta i TS anaesthesia machine is prepared when the patient
returns to controlled ventilation.
HLM mode - activated
When HLM mode is activated the following alarms are
disabled:
-
CO2
-
Respiration Rate
-
Expired minute volume
-
Apnea
HLM mode - deactivated
The Siesta i TS anaesthesia machine will automatically
cancel the HLM mode, when the automatic ventilation is running, and
the measured expired minute volume is increased by more than 70 %
over a period of two minutes.
In addition to this, the user can
cancel the HLM mode at any time. When the HLM mode is cancelled,
all the alarms will be reactivated.
Benefits
-
Alarm silence- even when the
ventilator is running
-
Optional ventilation modes
during
HLM perfusion
-
Automatic cancellation of the HLM
mode
-
Active system alarms at any
time
Safety
To keep the high level of patient saftety the Siesta i TS
system alarms will be active at any time.
