INTENDED USE
Breathing circuits and related accessories (Mount catheter,
reservoir bag, gas monitoring line, face mask, CPAP mask,
PEEP valve), single use, for anaesthetic apparatus and lung
ventilators, to conduct gases and/or vapour from the appa-
ratus (V) to the patient (P). DEAS breathing circuits are man-
ufactured in compliance with EN ISO 5367 standard. This
device is intended for short term use (less than 30 days)
in accordance with Directive 93/42/EEC and subsequent
amendments.

DIRECTIONS FOR USE
Carefullyreadtheproductlabelandthisleaetbeforeusing
the device. Open the packaging, checking that it is complete
and free from foreign bodies. Do not use the device if the
package is damaged. Any damage or opening in the pack-
age may affect sterility and/or device performance. In this
case do not use the device concerned.
BREATHING CIRCUIT
Connect the breathing circuit’s components as shown on the
graphical representation. Make sure that the connections
are properly secured. Pay special attention to the instruc-
tions provided below:
- if the breathing circuit contains a water trap to collect conden-
sation (Fig. C point 7), this must be kept vertical and in a posi-
tionwhichallowstheuidcollectinginsidethetubestodrain;
checkthelevelofllingfrequentlyandemptyitwhenneces-
sary. Then make sure that the water trap is properly closed;
- the monitoring ports (Fig. . B, C, D, E, F point 4) allow the
respiratory gases and/ or airway pressure to be checked and
should remain closed when not in use;
- if there is a gas monitoring line (Fig. D, E, F point 5) in the
breathing circuit, this must be connected to the control out-
let positioned on the ventilator (V). Regularly make sure that
large amounts of condensation are not forminginside as this
can stop the ventilator (V) from functioning properly;
- if the device has an expiratory port (Fig. D, E, F point 6) this
must not be sealed or obstructed. If it is obstructed this may
cause serious damage to the patient or even his death;
- if there are unidirectional valves in the device, check that they
areworkingproperlyandthedirectionofowpriortouse;
- if the circuit contains a pressure-limiting valve (Fig. E point
8), make sure that it is working properly before using it with
a patient. If it needs to be deactivated, use the appropriate
stop switch;
- the breathing circuits represented in Fig. D, E must only be
installed on models of ventilator (V) as indicated on the la-
bel. Installing the breathing circuit on a different model of
ventilator can prevent the system from working correctly.
Should the user want to install the circuit on ventilator mod-
elsnotindicatedonthelabel,theusershouldrstcontact
DEAS or its local representative to verify the compatibility of
the circuit to be installed with the relevant ventilator model.
ACCESSORIES
Catheter Mount: The Catheter Mount (Fig. A, B, C, D point 2)
isaexibleadaptorforjoiningorconnectingthebreathing
system to a tracheal or tracheostomy tube connector or to a
face mask. The patient side connector can be straight or at
an angle, with or without a cap. Connect the catheter Mount
to the breathing circuit as shown in the illustration. Remove
the cap (Fig. A, B, C, D point 3) only for the time strictly neces-
sary for carrying out tracheal aspiration or a bronchoscopy.
Opening the cap causes a loss of pressure in the breathing
system and the impossibility of ventilating the patient Rou-
tinely check the patency of the device. Using this device
causes the increase of the dead space.
Reservoir bag: The reservoir bag (Fig. A point 10) is a device
for inhaled anaesthesia induction or for ventilatory support. It is
connected to the anaesthesia machine or the manual breathing
unit. Check that it is functioning properly before using on the
patient. Do not use the device in case of malfunction.
Gas monitoring line: The gas monitoring line (Fig. D, E, F
point 5) is a device for checking respiratory gases and/or
airway pressure. It is connected to the control port of the
ventilator or monitoring apparatus and to the monitoring
port on the breathing circuit. Regularly make sure that large
amounts of condensation are not forming inside it as this
can stop the monitoring apparatus from functioning proper-
ly. Regularly make sure that large amounts of condensation
are not forminginside as this can stop the ventilator (V) from
functioning properly.
Face mask: The face mask (Fig. A point 1) is a device for
inhaled anaesthesia induction or for ventilatory support. It is
suppliedwithapre-inatedorinatablepad.Theinationof
thepadcanbeadjustedbyinjectingorremovingairthrough
a syringe which must be connected to the appropriate valve;
disconnect the syringe when the adjustment is complete
and check that the system is sealed. Make sure that the ap-
paratus (V) or the breathing circuit has an adequate system
for CO2 elimination. The mask must be removed if the pa-
tient suffers claustrophobia, skin irritation or retching. Using
this device causes the increase of the dead space.
