Which factor is known to increase the risk of respiratory complications in PACU patients?

Obesity or a history of sleep apnea is a significant factor known to increase the risk of respiratory complications in patients in the Post-Anesthesia Care Unit (PACU). Patients who are obese or have sleep apnea are more likely to experience problems such as airway obstruction and hypoventilation, particularly in the immediate postoperative period when they may be under the influence of anesthesia medications.

Patients with obesity often have altered respiratory mechanics and may find it difficult to achieve adequate ventilation and oxygenation after surgery. Additionally, those with a history of sleep apnea may have compromised airway patency, contributing further to respiratory distress. These factors can lead to serious complications, including hypoxemia and respiratory failure, if not monitored closely in the PACU setting.

Other factors like age over 60, smoking habits, and low blood pressure can influence patient outcomes, but the combination of obesity and sleep apnea specifically targets the respiratory system and significantly heightens the risk of complications related to anesthesia and recovery from surgical procedures.
