If signs of an airway obstruction are observed in a conscious patient, which method should be employed?

When signs of airway obstruction are observed in a conscious patient, abdominal thrusts are the recommended method for relieving the obstruction. This technique, often referred to as the Heimlich maneuver, involves standing behind the patient and applying a series of inward and upward thrusts just above the navel. This action increases intra-abdominal pressure, which can help expel the object blocking the airway.

Abdominal thrusts effectively create enough force to dislodge materials that are obstructing the airway, making them the most suitable choice in this scenario. It is essential to perform this maneuver carefully to avoid any injury, especially to vulnerable populations like children or the elderly.

Other methods, such as back blows alone, are less effective on their own for a conscious adult who is experiencing significant airway obstruction. Chest thrusts may be employed in specific situations, particularly with pregnant women or individuals who are too large for abdominal thrusts, but they are not the first line for a typical conscious adult patient. Simply encouraging the patient to breathe does not address the obstruction and may lead to further distress or harm. Thus, the appropriate and effective response to a conscious patient showing signs of an airway obstruction is to perform abdominal thrusts.
