14.3.3 Nitric Oxide Therapy
When the ventilator is used in conjunction with an Inhaled Nitric Oxide Delivery
System, the ventilator requires two NO scavenging filters (SLE part Nº N4110
connected in parallel with a dual exhaust hose assembly SLE part Nº N4110/10)
fitted to the exhalation block (remove the silencer). This is supplied as a complete
kit under SLE part Nº N4110/20. The flow of exhausted gas exceeds the
capability of a single scavenging filter.
Caution: After using the ventilator with Nitric Oxide therapy, rinse the
exhalation block with water before cleaning, disinfection or sterilization.
This is to remove any deposits of NO that could react during steam
autoclaving with water to form Nitrous acid or Nitric acid.
Warning: Using the ventilator with only one N4110 scavenging filter, (fitted
directly to the exhaust port) will cause a back pressure to be generated.
This will cause all the pressure readings to become slightly elevated.
