Distal expiration valves are used with the

EVE pediatric single-use tube system

Fisher & Paykel single-use tube system

WILAmed single-use tube system
A proximal expiration valve is used with the
EVE adult emergency
single-use tube system.
5.4.1 Connecting the distal expiration valve
The distal expiration valve is connected directly to the expiration port and
linked to the tube system (see Fig. 67).
5.4.2 Connecting the proximal expiration valve
The proximal expiration valve is connected between the flow sensor and
the tube system. The control line of the valve is connected to the
expiration outlet of the device using an adapter (see Fig. 66).
5.5 Installing the flow sensor
EVE
TR
measures pressure and flow via the flow sensor (PNT).
The measurement is taken proximally between the Y piece and the tube
connector. For this purpose, a flow sensor head is fitted between the two
parts. The differential pressure resulting from the flow sensor head's
resistor is a measure of the volume flow. Separate flow sensors are
available for adults and children.
Flow sensor type Dead space
Flow sensor for preterm infants and
newborns (PNT B) (optional) 0.6 ml
Flow sensor, child 2.7 ml
Flow sensor, adult 11 ml
The flow sensor is connected between the expiration valve and the
endotracheal tube (ETT). Fig. 69 and Fig. 70 show the additional
connection of a CO
2
sensor and a bacterial filter.
