The Post-Anesthesia Care Unit (PACU) is a specialized area in a hospital where patients are monitored after undergoing surgery or other procedures that require anesthesia. In the PACU, healthcare professionals assess patients' vital signs, manage pain, and ensure they recover safely from the effects of anesthesia before they are discharged to a regular hospital room or sent home. Patients typically stay in the PACU for a few hours, depending on their individual recovery needs. The staff in the PACU includes nurses and anesthesiologists who are trained to recognize and address any complications that may arise during the recovery process, ensuring patient safety and comfort.
