Final answer:
A Nitrous oxide mask is used for inhalation sedation, providing patients with a mixture of nitrous oxide and oxygen to ensure comfort and reduce pain during medical procedures.
Step-by-step explanation:
The piece of equipment used in the administration of inhalation sedation is a Nitrous oxide mask. Inhalation sedation, also known as laughing gas, is administered using this mask, which delivers a mixture of nitrous oxide and oxygen to the patient. This form of sedation is often used in dentistry and minor surgical procedures to relax patients and reduce pain and anxiety during treatment. Unlike other options such as endotracheal tubes or laryngoscopes, which are used for intubation, the nitrous oxide mask allows the patient to breathe the sedative gas mixture comfortably through their nose and mouth.
