When the airway is not maintained patent, respiratory failure can occur as a direct consequence. This condition arises when the lungs are unable to perform their primary function of gas exchange effectively due to blockage or obstruction in the airway. When airflow is reduced or stopped, the body cannot receive sufficient oxygen or expel carbon dioxide, leading to a failure in respiratory function.

In cases where the airway is compromised, even temporarily, the body's systems start to deteriorate rapidly due to lack of oxygen. Signs of respiratory failure may include difficulty breathing, abnormal breathing rates, and various levels of consciousness depending on the severity. Ensuring that the airway remains patent is crucial in both emergency and routine medical care, as it is often the key to maintaining adequate oxygenation and preventing life-threatening complications.
