14.3 Patient Circuits, Humidification
and Nitric Oxide Therapy
14.3.1 Autofeed Humidification chambers
When using autofeed humidification chambers the
waterbag should be mounted higher than the max
Delta P or MAX PIP being used.
To calculate the approximate height of the water
bag use the following conversion:
1 mbar = 1cm, then add 25cm to the calculated high
for the final height of the bag.
Mounting the bag lower could allow the ventilator to
pressurize the bag and thus prevent the chamber
from filling with water. Also, the bag in return
pressurizes the chamber which could cause high or
sustained pressure alarms to be triggered.
14.3.2 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.
MAX
Delta P
or
MAX PIP
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.
