Connecting A Non-Rebreathing System (Optional) - Dräger Perseus A500 Instructions For Use Manual

CAUTION
Risk due to changed hose lengths
Changed hose lengths can change resistance
and compliance. Especially for neonates, this
may cause increased or decreased ventilation
volumes.
For neonates in particular, do not use flex hoses.
Accessories or accessory components such as
filters may change dead-space, compliance, or
resistance.
Calculating the resistance of the breathing
system and connected accessories
To keep the patients' work of breathing as low as
possible, according to ISO 8835-2 a total
inspiratory and expiratory resistance of 6.0 hPa
(cmH O) at 60 L/min may not be exceeded.

The following formula is used to calculate the
resistance (R):
R =
Inspiration
R _ + R
Breathing system insp
+ R + R

Only include resistance data in calculations that
was taken under the same flow conditions (for
adults 60 L/min, for pediatric patients 30 L/min,
and for neonates 5 L/min).
If necessary, take into consideration additional
parts such as water traps or additional hoses.
Resistance of the breathing system, see page 226.

Connecting a non-rebreathing system
(optional)
This connection is only possible with the option
External fresh-gas outlet.
WARNING
Insufficient gas supply to the patient
Non-rebreathing systems are only suitable
and intended for manual ventilation or
spontaneous breathing and may only be
connected to the external fresh-gas outlet.
When using a non-rebreathing system,
ensure an adequate gas monitoring.
WARNING
Risk of excessively high airway pressure
Without a pressure-relief valve or breathing
bag, airway pressure may become too high.
Only connect breathing systems with
breathing bags or pressure-relief valves
which comply with ISO 8835-2.
Strictly observe instructions for use of the non-
rebreathing system and transfer hose.
+
To prevent contaminating the ambient air, connect
the gas outlet of the breathing system with the inlet
on the AGS. Use transfer hose with overpressure
valve complying with ISO 8835-3.
WARNING
Risk of faulty gas delivery
O and CO and any anesthetic gases must
2 2
also be monitored for non-rebreathing
systems.
The sample line must be connected to the
elbow and the water trap on Perseus.
