Once the ideal flow and the pulmonary capacity of the patient have been determined, adjust
the gas elimination valve as explained in paragraph 6.4 ‘Evacuation of exhaled gases’ .
It is possible to change the percentage of nitrous oxide using the % knob (C – figure
A10).
The columns display the amount of Nitrous oxide and Oxygen that is delivered in
litres/min.
The sum of the two flows is the amount initially set based on the patient's respiratory
capacity.
PROCEDURE SPECIFICATIONS FOR
CHILDREN: PROCEDURE SPECIFICATIONS FOR
ADULTS:
The flow for CHILDREN is approximately
4-5 Lt/min.
- Turn the 'FLOW' knob clockwise to set the
flow at 4/5 l/min and instruct the patient to
breathe for ~1 minute.
- Check the flow setting on the O
2
flow
column (D - figure A10).
- The bag must be half full half empty .
The flow for ADULTS is approximately 6-
8 Lt/min.
- Turn the 'FLOW' knob clockwise to set
the flow at 6-8 l/min and instruct the
patient to breathe for ~1 minute.
- Check the flow setting on the O
2
flow
column (D - figure A10) .
- The bag must be half full half empty .
Using the % N
2
O knob (C - figure A10) administer nitrous oxide, set it at 20% , wait a few
minutes and see how the patient reacts.
If the patient is not sedated gradually increase the percentage (ex 30%).
THE PERCENTAGE OF NITROUS OXIDE ADMINISTERED TO THE PATIENT MUST BE :
THE LOWEST POSSIBLE LEVEL TO OBTAIN GOOD SEDATION (BASE LINE).
Once the patient's BASE LINE has been established, note down the FLOW value and
the %N2O on his/her medical record, this data will be useful for future procedures.
THE GAS MIXTURE THAT IS ADMINISTERED TO THE PATIENT:
MUST NOT EXCEED 70% NITROUS OXIDE
MUST NOT BE LOWER THAN 30% OXYGEN
If the patient reports symptoms of discomfort (nausea, dizziness, head
ache) immediately stop administration.
The “FLUSH” button (B - figure A10) is located on the device.
By pressing this button the bag will fill with oxygen.
By pressing the bag we will administer the patient with elevated quantities
of pure oxygen.
