iVent201 Operator's Manual
65
As a safety measure, within a few seconds after the
patient weight selection pop-up appears, the iVent
201
generates airflow to see if resistance is encountered
in the patient circuit. (The patient may be
connected). If a possible patient connect is
confirmed, the iVent
201
enters an auto-start mode of
pressure control that will be safe for pediatric
through adult patients.
• If the iVent
201
detects resistance, it sounds an
alarm and begins ventilating in SIMV
pressure control mode at a rate of 15 breaths
per minute, P(INSP) 20 and a PEEP of 5.
• If the iVent detects no airway resistance, it
enters Standby mode. During this state, if
flow is detected in the patient circuit the
iVent
201
will also auto-start.
3.1.2 O.V.T.
The patient circuit must be tested each time it is connected, so if
you are reconnecting a patient circuit or using a new one, you
must perform the Operational Verification Test (O.V.T.). This
test, which takes less than a minute, checks the integrity of the
breathing circuit.
Two plastic caps for covering the ends of the patient circuit are
required for the O.V.T. They are included with all patient
circuits offered by Versamed.
To perform an O.V.T.:
