4. If it is intended to use very low fresh gas flows in a circle breathing system, there must
be a means to analyse the oxygen and vapour concentration in the inspiratory limb.
(Under other circumstances these may be monitored at the anaesthetic machine fresh
gas outlet.)
5. A new, single-use bacterial/viral filter and angle piece/catheter mount must be used for
each patient. It is important that these are checked for patency and flow, both visually
and by ensuring gas flow through the whole assembly when connected to the breathing
system.
F. VENTILATOR
1. Check that the ventilator is configured correctly for its intended use. Ensure that the
ventilator tubing is securely attached. Set the controls for use and ensure that adequate
pressure is generated during the inspiratory phase.
2. Check that disconnect alarms are present and function correctly.
3. Check that the pressure relief valve functions correctly at the set pressure.
G. SCAVENGING
Check that the anaesthetic gas scavenging system is switched on and functioning. Ensure
that the tubing is attached to the appropriate exhaust port of the breathing system,
ventilator or anaesthetic workstation.
H. ANCILLARY EQUIPMENT
1. Check that all ancillary equipment (such as laryngoscopes, intubation aids eg intubation
forceps, bougies, etc.) which may be needed is present and in working order. Ensure that
all appropriate sizes of face masks, laryngeal masks, airways, tracheal tubes and
connectors are available, and checked for patency at the point of use.
2. Check that the appropriate laryngoscopes function reliably.
3. Check that the suction apparatus is functioning and all connections are secure; test for
the rapid development of an adequate negative pressure.
4. Check that the patient trolley, bed or operating table can be rapidly tilted head-down.
