Assess sedation level using a valid scale. A patient who is difficult to arouse is at extreme risk. Do not rely solely on pulse oximetry; capnography (EtCO2) provides the earliest warning of hypoventilation.
If respiratory rate falls below 8 breaths/min or sedation deepens, stop the PCA, stimulate the patient, administer naloxone as prescribed, and call the Rapid Response Team. Never assume a low SpO2 alarm is a machine error.
