Heimlich manoeuvre is indicted for:
**Core Concept**
The Heimlich manoeuvre is a first aid technique used to relieve upper airway obstruction caused by food, foreign objects, or other materials. It involves a series of abdominal thrusts to increase pressure in the thoracic cavity and dislodge the obstructing object.
**Why the Correct Answer is Right**
The Heimlich manoeuvre works by increasing the pressure in the thoracic cavity, which in turn increases the pressure in the upper airway. This increased pressure helps to dislodge the obstructing object from the trachea. The manoeuvre is typically performed by a bystander or first responder who stands behind the person experiencing the obstruction and wraps their arms around the person's waist. They then make a fist with one hand and place it just above the person's navel, with their other hand on top of the fist. A quick upward thrust is then applied to the abdomen, which helps to dislodge the object.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the Heimlich manoeuvre is specifically designed to relieve upper airway obstruction, not lower airway obstruction.
**Option B:** This option is incorrect because the Heimlich manoeuvre does not involve any medical equipment, such as a defibrillator or oxygen tank.
**Option C:** This option is incorrect because the Heimlich manoeuvre is not a surgical procedure, but rather a first aid technique.
**Clinical Pearl / High-Yield Fact**
The Heimlich manoeuvre should be performed in a standing position, with the person experiencing the obstruction standing upright and the bystander standing behind them. This helps to increase the effectiveness of the manoeuvre and reduces the risk of injury to the person experiencing the obstruction.
**Correct Answer:** C. Upper airway obstruction.
