What is a common sign of airway obstruction that PACU nurses should monitor for?

Stridor or wheezing sounds are key indicators of airway obstruction that PACU nurses need to be vigilant about. These sounds result from turbulent airflow through partially obstructed airways and can signal that there is a narrowing or blockage present, which may occur due to factors such as edema, secretions, or foreign bodies.

Identifying stridor or wheezing is critical because airway obstruction can lead to inadequate ventilation and potential respiratory failure if not addressed promptly. In the PACU, where patients are closely monitored post-anesthesia, recognizing these signs allows for timely interventions, such as administering supplemental oxygen, using bronchodilators, or preparing for advanced airway management if necessary.

The other options do not directly indicate airway obstruction. Increased perspiration may indicate anxiety or pain, decreased heart rate is more commonly associated with vagal stimulation which does not relate to obstruction, and an increased appetite is not relevant in the context of monitoring airway status. Understanding these signs is essential for PACU nurses to ensure patient safety and facilitate a smooth recovery.
