NOTE Parameters for all the iVent

201’s possible ventilation modes are set when

you choose a patient weight upon startup. For a view of the default

parameters according to weight, refer to Table 1: Default Start Parameters for

Volume Ventilation for 10 kg to 70 kg through Table 4, page 107.

The default selection for patient weight range for the iVent

201 is 70+kg. This

may be changed using the Configuration utility described on page 185.

As a safety measure, within a few seconds after the patient weight selection pop-

up window appears, the iVent

201 generates airflow to see if resistance is

encountered in the patient circuit, which means that the patient is connected.

NOTE This is an optional feature, not available in all iVent

201 units.

 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

201 detects no airway resistance, it enters Standby mode.

During this state, if flow is detected in the patient circuit the iVent

201

performs an auto-start.

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 one minute,

checks the integrity of the breathing circuit and audible alarm functionality.

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.:

1. Rotate the Control Knob until the O.V.T. option is selected in bright blue.

2. Press the Control Knob until you hear a click. The O.V.T. Instructions pop up

window appears (Figure 29).
