WARNING
ATRC may induce autotriggering. If autotriggering occurs, first check the patient,
breathing circuit, and other possible causes.
NOTE
Incorrect tube type or ID setting can endanger the patient. Make sure to set them
properly.
9.12 IntelliCycle
IntelliCycle intelligent synchronous technology means that the user can set [Exp%] to [Auto]
in CPAP/PSV, V-SIMV, P-SIMV, PRVC-SIMV, AMV and DuoLevel modes and ventilator
will adjust [Exp%] dynamically by adaptive algorithm through extracting and analysing the
waveform characteristics. This way, ventilator monitors and adapts [EXP%] according to
patient condition and needs automatically, and ends inspiration with more synchrony.
9.13 O
2
Therapy
O
2
therapy is a method to increase O
2
concentration in the airway at normal pressure through
simple tube connections. O
2
therapy is a medical measure which can increase O
2
concentration in the alveolar gas and facilitate O
2
diffusion so as to increase PaO
2
and SpO
2
saturation and relieve or correct hypoxia by increasing O
2
concentration in the inspired gas.
O
2
therapy is a way for hypoxia prevention or treatment, providing O
2
concentration higher
than that in the air.
WARNING
During O
2
therapy, only the O
2
concentration FiO
2
, O
2
flow, SpO
2
, and pulse rate
are monitored.
During O
2
therapy, all physiological alarms are shielded except O
2
concentration
and SpO
2
module physiological alarms.
Airway pressure and expiration-dependent ventilation parameters, such as flow,
minute volume, or apnea, are not monitored.
Use SpO
2
monitoring for patients who are dependent only on an increased defined
O
2
concentration. Otherwise, a deterioration in the patient’s condition cannot be
recognized.
Only use oxygen masks or nasal catheters for O
2
Therapy. Do not use masks for
non-invasive ventilation (NIV). The patient may be at risk if unsuitable masks are
used.
