) onto the
device outlet port.
2. Now connect the blue connector stub of the pressure-
measurement tube (
1
) to the connection of the device

Double patient circuit (VENTI
logic
LS only)
In addition to the ventilation tube which delivers air to the patient, the pressure-
measurement tube and the valve control tube, the double patient circuit also has an
exhalation tube which routes exhaled air back to the device and into the ambient air.
On the double patient circuit, the patient valve is located on the exhalation tube.
Proceed as follows to connect up the double patient circuit.
1. Plug the ventilation tube (
1
) onto the device outlet
port of the VENTI
logic
LS.
2. Plug the exhalation tube (
3
), on the end of which is
the patient valve (
4
), onto the device inlet port for
exhaled air underneath the device outlet port.
3. Now connect the blue connector stub of the pressure-
measurement tube (
2
) to the connection of the device
which is likewise blue and marked
