CIRCUIT RESISTANCE
It is important to check the inspiratory and expiratory resistance specification of
the patient circuits used with the iVent
TM
201 ventilator to ensure they do not
exceed the following limits when adding attachments or other components or
subassemblies to the breathing circuit:
ï‚· O.6 KPA (6cmH2O) at 60 L/min for adult patients.
ï‚· O.5 KPA (5cmH2O) at 30 L/min for pediatric patients.
OTHER CONNECTIONS
HME
If required, a Heat and Moisture Exchanger may be placed between the flow
sensor and the patient connection.
CAUTION A contaminated HME filter can impede the ventilator’s Patient Disconnect
alarm detection. Do not use any filter that appears to be discolored or filled
with water.
NOTE Adding attachments, components or sub-assemblies to the iVent
TM
201
breathing circuit may increase the pressure gradient.
MDI
To administer medication, install an adapter for MDI treatment between the flow
sensor and the patient connection.
USING THE IVENT
TM
201 WITH HEATED
HUMIDIFICATION (1.4 STEPPER BASED MODELS
ONLY)
The following procedures explain how to connect the iVent
TM
201 to a heated
humidifier.
To use the iVent
TM
201 with a heated humidifier:
1. Disconnect the Inspiratory Limb from the ventilator outlet of the iVent201
and reconnect it to the humidifier outlet.
2. Remove the one-way valve from the Patient Wye and reconnect the tube.
