What should be done when ready to discontinue nitrous oxide sedation?

When discontinuing nitrous oxide sedation, it is paramount to administrate 100% oxygen immediately after stopping the nitrous oxide. This procedure helps to mitigate the risk of diffusion hypoxia, which may occur as the nitrous oxide leaves the body rapidly and can displace oxygen in the lungs. Administering pure oxygen facilitates the quicker elimination of nitrous oxide from the bloodstream and tissues, ensuring that the patient is adequately oxygenated and minimizing the potential for any adverse effects associated with abrupt cessation of nitrous oxide.

This practice aligns with the physiological adjustments required by the body after sedation, as it aids in restoring normal oxygen levels more rapidly. Ensuring the patient receives 100% oxygen provides a safeguard against feelings of dizziness or lethargy that may result from reduced oxygen saturation. Overall, this method reinforces patient safety and comfort during the recovery phase from nitrous oxide sedation.
