What vital sign changes should a PACU nurse be particularly vigilant for in patients with a history of respiratory issues?

In patients with a history of respiratory issues, it is crucial for a PACU nurse to closely monitor changes in respiratory rate and oxygen saturation. These vital signs are indicators of the patient's respiratory function and can reveal underlying complications, such as atelectasis, pneumonia, or airway obstruction, which are common risks after anesthesia and surgery.

A change in respiratory rate can signify that the patient is either experiencing respiratory distress or is compensating for other issues, such as pain or metabolic imbalances. Oxygen saturation is equally important, as it reflects how well oxygen is being delivered to the body's tissues. An adequate level of oxygen saturation is essential for recovery and prevents hypoxia, which can lead to serious complications if not addressed promptly.

The other changes mentioned are less indicative of immediate respiratory distress in this specific patient population. Monitoring body temperature is important, but an increased temperature may not directly relate to respiratory issues. A decreased heart rate is not typically associated with respiratory problems and can reflect other physiological changes. Observing a regular heartbeat and stable blood pressure indicates cardiovascular stability, which, while important, does not prioritize the respiratory concerns inherent in patients with a history of respiratory issues. Focusing on respiratory rate and oxygen saturation specifically addresses the unique needs of these patients in the PACU setting
