26.5 N5238/50 Heated Patient Circuit For NO Therapy
Temperature port 450mm from ET Manifold. This non-sterile circuit is for
single patient use only. It is designed to be used in combination with a Servo
controlled humidifier and a Nitric Oxide Therapy System or SLE INOSYS Inhaled
NO System. With dual hose scavenger filter.
It is recommended that a high quality bacteria filter (SLE part no. N2029) is fitted
at the fresh gas connection to the humidifier inlet, however the circuit may be
used without. Connect the patient circuit as detailed below. Drain water trap
regularly by removing the bottom cup. (Circuit pressure is not lost when cup is
removed).
1. Humidifier Supply Line
If a bacteria filter is being used, fit the very short piece of transparent tube to the
ventilator outlet marked ‘Fresh Gas to Patient’. Fit the bacteria filter into this tube
(Make sure the arrow points towards the patient). Take the loose length of tube
and connect the free end of this to the bacteria filter and the coupling end to the
humidifier inlet. If a bacteria filter is not being used, connect the loose length of
tube directly between the ‘Fresh Gas to Patient’ ventilator outlet and the
humidifier inlet.
2. Inspiratory Supply Line (Blue tube)
Take the main patient circuit and fit the blue tube with the large connector to the
humidifier outlet. Plug the electrical connector into the humidifier heated wire
supply.
3. Expiratory Supply Line (Clear tube)
Take the clear tube with the large connector and fit to the exhalation port of the
ventilator. Position water trap in an upright position at the lowest point in the
circuit limb.
4. Proximal Airway Pressure Line
Connect the small diameter clear tube from the patient circuit to the proximal
airway port on the ventilator.
5. Temperature Monitoring
Two ports are provided for dual temperature probes, one in the connector on the
humidifier outlet (next to the heated wire inlet) and a second port in tee piece (L)
connected in the blue inspiratory supply line (R).
Inhaled Nitric Oxide Delivery
Note: Connect the NO/NO
2
hose scavenging filter directly to the exhalation
block. Do not use the N2186/01 silencer with NO Therapy.
Warning: It is very important that the Nitric Oxide Monitor Line is close to
the ET connector and the Nitric Oxide Delivery Line is 20-25mm from the
humidifier temperature probe port to allow adequate gas mixing.
Warning: Nitrous acid & Nitric acid can be formed when Nitrogen Dioxide
and Water are present. After use ensure that any condensate on the
ventilator gas ports is removed by wiping with a dry lint free cloth.
