Answer Key

1. Drowning/choking is defined as the obstruction of the respiratory tract, which prevents the body from receiving sufficient oxygen. This oxygen deprivation causes vital organs, particularly the brain, to lose function, leading to irreversible damage or death if not addressed quickly.
2. Dry drowning occurs when the respiratory tract closes due to a spasm in response to water, preventing water from entering the lungs but also blocking air. Secondary drowning happens hours or days after a water incident when a small amount of inhaled water irritates the lung tissue, causing a buildup of fluid (pulmonary edema).
3. Mechanical asphyxia is a type of choking caused by an external force or pressure that physically blocks the airways. Common causes include the compression of the throat or chest, suffocation from falling face-down on a soft surface, or entanglement in long cords or belts.
4. Cyanosis is the bluish or purplish discoloration of the skin resulting from severe oxygen deficiency in the blood. This symptom is a critical indicator of oxygen deprivation and is most commonly observed on the lips, fingertips, and nail beds.
5. For a partial obstruction where the person can still cough and speak, the correct approach is to encourage them to continue coughing, as this is the body’s most effective mechanism for clearing the airway. For a complete obstruction where the person cannot breathe or make sounds, the Heimlich maneuver must be performed immediately.
6. After safely removing a drowning victim, the rescuer must first ensure their own safety and the victim’s. The second step is to immediately call for emergency medical help (e.g., 112). The third step is to check the victim’s consciousness by tapping their shoulders and calling out to them.
7. For an adult drowning victim, it is recommended to start with 5 initial rescue breaths to quickly deliver oxygen to the lungs. After this, the standard cycle of 30 chest compressions followed by 2 rescue breaths should be performed continuously until medical help arrives or the person recovers. The compression rate should be 100-120 per minute with a depth of 5-6 cm.
8. For individuals who are pregnant or excessively overweight, the standard abdominal thrusts of the Heimlich maneuver are not used. Instead, chest thrusts are applied by placing the fist in the middle of the breastbone and performing quick, forceful inward and upward thrusts.
9. Prevention methods for drowning include learning to swim, ensuring continuous and active adult supervision of children near water, and using safety barriers like fences around pools. It is also crucial to wear a life jacket during water sports or boating and to avoid entering the water while under the influence of alcohol or drugs.
10. It is essential for a rescued person to seek medical evaluation due to the risk of secondary drowning. Even a small amount of inhaled water can lead to pulmonary edema hours or even days later, which can be a life-threatening condition requiring urgent medical intervention.
