Step-by-step explanation:
Inhalation sedation is administered through the respiratory tract with the use of an inhaled mixture of nitrous oxide (N2O) and oxygen (O2). Inhalation sedation is a method of delivering anesthesia that involves breathing in a gas mixture through a mask or nasal tubes. The gases are absorbed through the respiratory tract, allowing them to reach the bloodstream and produce a sedative effect. This method is commonly used in dental procedures to help patients relax and reduce pain and anxiety.
