How should an EMT respond to an adult with an obstructed airway?

Performing abdominal thrusts is the appropriate response for an adult with an obstructed airway, particularly when the obstruction is severe and the person is unable to breathe, cough, or speak. The purpose of abdominal thrusts is to create an increase in intra-abdominal pressure that can help dislodge an object blocking the airway.

After administering the thrusts, it is essential to reassess the situation to determine if the obstruction has been cleared, allowing the patient to breathe effectively again. This practice ensures that the EMT can continuously monitor the effectiveness of the intervention and provide further assistance if necessary.

In contrast, administering oxygen, encouraging coughing, or merely positioning the patient upright would not address the immediate and critical issue of an obstructed airway. These options do not resolve the blockage and could lead to serious consequences if the obstruction remains unaddressed.
