Term	Definition
Ambu Bag	A professional medical tool used for artificial respiration, consisting of a balloon bag, a one-way valve, and a face mask. The rescuer squeezes the bag to deliver air to the patient’s lungs, allowing for effective and hygienic ventilation.
Anaphylaxis	A severe allergic reaction that can cause the airways to swell and close, obstructing breathing and potentially requiring artificial respiration.
Artificial Respiration	A basic life support procedure used to support the respiratory function of an individual whose breathing has stopped or is insufficient. It involves externally providing air to the lungs to supply oxygen and facilitate carbon dioxide removal.
Cardiopulmonary Resuscitation (CPR)	An integrated first aid technique that combines chest compressions (heart massage) with artificial respiration (rescue breaths). It is performed on individuals who are unresponsive, not breathing, and have no pulse to circulate oxygenated blood to vital organs.
Chest Compressions	The act of applying rhythmic pressure to a person’s chest to manually pump blood from the heart. In adults, this is done on the lower half of the sternum to a depth of 5-6 cm at a rate of 100-120 per minute.
Heimlich Maneuver	A first aid procedure used to dislodge a foreign object obstructing the airway. If breathing does not resume after the obstruction is cleared, artificial respiration may be required.
Look-Listen-Feel (Bak-Dinle-Hisset)	A method for checking if a person is breathing. For 10 seconds, the rescuer looks for chest movement, listens for breath sounds, and tries to feel exhaled air on their cheek.
Mechanical Ventilator	An advanced medical device used in hospitals to take over or support a patient’s breathing. It provides controlled and long-term respiratory support for patients with severe respiratory failure.
Sniffing Position (Koklama Pozisyonu)	The correct head position for opening an infant’s airway. The head is tilted back only slightly, as if the baby is sniffing the air, to prevent the airway from being blocked by overextension of the neck.
