How does impaired consciousness threaten a person's airway?

When consciousness is impaired, the muscles that keep the airway open lose tone and protective reflexes weaken. The tongue can relax and fall back toward the throat, partially or completely blocking the airway. This loss of muscle control is the main way impaired consciousness threatens breathing and oxygen delivery. Other possibilities don’t explain the mechanism as clearly: the tongue moving forward wouldn’t typically block the airway, tight chest muscles are about effort of breathing rather than causing obstruction, and noisier breathing is more a sign of airway compromise than the reason it’s at risk. In this situation, checking for a clear airway and positioning the person to keep the airway open is essential, with help summoned if breathing is absent or disrupted.
