Abstract:
Hypoxaemia in the postanaesthesia care unit is common and the majority is caused by hypoventilation or upper airway obstruction due to the (residual) effects of anaesthetic and analgesic agents. We present a case of upper airway obstruction caused by vocal cord dysfunction, a less frequently occurring aetiology. The patient's case suggests a notable relationship between procedural laryngeal stimulus and the onset of symptoms. Approach to the diagnosis and flexible laryngoscopy to either rule-in or rule-out several relevant differentials are discussed.

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
