Connecting the VT PLUS HF
Pneumatic Connections
The VT PLUS HF can be connected to a ventilator and a test load in either a bi-
directional or uni-directional flow configuration. The following is a description of various
connections on the VT PLUS HF :
High Flow (inlet and exhaust):
The outer diameter of the high flow ports is a standard
22 mm fitting to allow connection using patient hoses. The inner diameter of the high
flow ports is designed to accept 15 mm male respiratory fitting such as endotracheal
tubes, gas sampling adapters, etc.
Pressure inside the high flow port should not exceed
±
120 cmH
2
O.
Only dry gasses should be measured using the high-flow port. Do not use this
port to measure exhaled or artificially humidified gasses.
Low Flow (inlet and exhaust): The outer diameter of the low-flow ports is a standard
15 mm to allow connection with standard respiratory fittings such as gas sampling Y-
pieces and gas sampling adapters. The inner lumen of the low-flow ports are threaded to
accept a standard ¼” NPT fitting.
Pressure inside the low-flow port should not exceed
±
120 cmH
2
O.
Only dry gasses should be measured using the low-flow port. Do not use this
port to measure exhaled or artificially humidified gasses.
High Pressure (+ and -): The high-pressure ports are primarily designed for testing wall
and tank pressurized gas sources. The connector mates to standard oxygen DISS fittings
as used on oxygen supply hoses. Note that only the + side can be used to measure fluid
pressure.
Applied differential pressure to either side of the high-pressure port should not
exceed 100 psi.
