7.1.8.
Controlled / Supported Pressure Level
In controlled pressure mode, inspiratory pressure (P. INSP) is configurable. Supplementary
pressure (P. SUPP) is configurable in supported Pressure Support, SIMV modes and
tBiLevel.
7.1.9.
O
2
Cencentration
The setting range of O
2
concentration is 21 ~ 100%.
There is also an absolute minimum limit of alarm is 18% O
2
which is independent of
operating setting. If the value reaches below this point, O
2
fail alarm will sound.
The screen only displays O
2
concentration of 21% or higher. The alarm is delayed 60
seconds after changing the O
2
concentration setting.
7.1.10.
Sigh Time
It is support a big volume of the patient by providing 1.5times inhalation volume per each
certain breathing in volume mode.
The maximum of volume is 1,500ml.
7.1.11.
Proximal Sensor On/Off
This option must be used for low flow pressure / flow supplemented patients who require
precise flow measurements and tube compensation such as premature and neonate
patients.
It is safe to use this function in supported ventilation below 200ml.
Appropriate sensor (for adults, for infants) must be used depending on the patient.
7.1.12.
Mask On/Off
This option can be turned On/Off in all modes except for O
2
stream and HFV.
Once turned On, leakage compensation ability is increased.
7.1.13.
En_Sense
The EnSense means Inhalation-Trigger Enable Sensitivity. It is the function for next
inhalation trigger is triggered only when a certain volume exhalation must be taken place
proportionally to the inhalation volume.
If this function is used, it allows trigger of the patient and can restrict or prevent retrigger
phenomena and mandatory breathing can be successfully maintained.
Before the exhalation volume reach to En_Sense[%] of Vins(Supported Volume), the
trigger(Inhalation Trigger) is not enabled and system be could not go to next Inhalation
Phase by ‘En_Sense’ Function.
In case, Patient has high airway resistance and too much Ascites(Abdominal Dropsy). The
function has another solution to protect retriggering.
