eating too much food
Drinking too much water
Suffocation
The brain or nerves that control respiration can be affected by:
electrical injury
hold your breath for too long
eating spicy food
poisoning
During exhalation, the amount of oxygen in the air is higher than the amount of carbon dioxide.
True
False

uncontrollable laughter
Breathing rate increases
flushing then blueness of the head
consciousness gradually lost
Which of the following can cause asphyxia?
Eating spicy food that makes breathing difficult.

Choking on food or a foreign object.
Sleeping too long without waking up.
How does drowning cause asphyxia?
The heart stops pumping immediately after falling into water.
The body absorbs too much water, making it too heavy to breathe.
The lungs stop working as soon as they touch water.
Water blocks the airway, preventing oxygen from reaching the lungs.
What should you do first if you suspect someone is experiencing asphyxia?
Check their airway and remove any obstruction if safe.
Pour cold water on their face to wake them up.
Shake them forcefully to restart their breathing.
Which medical condition can lead to asphyxia?
High blood pressure.

Severe asthma.
Excessive sweating.

It can be treated by drinking more water.
It helps the body learn how to survive without oxygen.

False
During inhalation, the amount of oxygen in the air is higher than the amount of carbon dioxide.
True
False
Why does choking lead to asphyxia?
The body forgets how to inhale air.
A foreign object blocks the airway, preventing oxygen from entering the lungs.
The stomach expands and presses against the lungs.
The brain stops producing oxygen, making breathing impossible.
