NOTES ON SEDATIVE ANALGESIA

The gas sources are nitrous oxide (N
The gas mixture delivered enters the administration circuit, is inhaled by the patient, and then discharged
outside the practice.
There are two one-way valves on the mask to ensure proper gas flow.
PRINCIPLE OF ANALGESIA
Nitrous oxide is a laughing gas, it is an inert, colourless, sweet-tasting, chemically stable, non-flammable
and explosive gas, but it can fuel combustion.
It is a non-toxic narcotic for inhalation, which does not stimulate the respiratory tract and does not
combine with haemoglobin.
It takes effect quickly after being inhaled into the body. It begins its analgesic activity within 30-45
seconds of inhalation.
Normal breathing allows 90% of nitrous oxide to be eliminated, 10% evaporates from the patient's skin
more slowly
SEDATION SHOULD ALWAYS BE MONITORED USING A PULSE OXIMETER WITH
CUSTOMISED ALARM THRESHOLDS.
Vital parameters, pulse and oxygen saturation show whether the patient is in good condition and whether
sedation has the desired effect.
Normally, during sedation, oxygen saturation increases, the pulse slows down and the patient relaxes.
When a patient is sedated with e.g. 50% nitrous oxide, the oxygen flow is 50%, the patient breathes
more oxygen than normal (oxygen in the air ~ 21%).
If the oxygen saturation falls below the set value, the pulse oximeter emits an alarm.
If oxygen saturation falls below 85%, for example, nitrous oxide sedation must be discontinued
immediately, as there is a risk that nitrous oxide and oxygen have been exchanged and the mixture
administered contains 80% nitrous oxide.
If beats rise or fall above the set value, the pulse oximeter will sound an alarm.
It could indicate an overdose or too deep sedation. In this case, reduce or set to 0 the flow of nitrous
oxide and administer pure oxygen to the patient.
If the saturation indicated by the pulse oximeter falls during the administration of pure oxygen, switch off
the unit immediately and contact service.
