Describe the use of pulse oximetry in sedation.

Pulse oximetry is a critical tool in sedation because it measures the oxygen saturation of the patient's blood. This technology uses light absorption characteristics of hemoglobin to assess how effectively oxygen is being transported throughout the body. By providing real-time data on oxygen levels, pulse oximetry enables dental professionals to monitor the patient's respiratory status during sedation. Maintaining proper oxygenation is vital, as inadequate oxygen levels can indicate hypoxia, necessitating immediate intervention.

While pulse oximetry does not directly monitor heart rate, depth of sedation, or blood pressure, these parameters are also important during sedation. Heart rate is typically monitored through a separate device, and blood pressure is assessed using a sphygmomanometer or automatic blood pressure cuff. Depth of sedation is often gauged through clinical observation and specific sedation scales, rather than through pulse oximetry. Thus, the primary function of pulse oximetry in this context is indeed the measurement of oxygen saturation, making it crucial for safe sedation practices.
