Lung Function and Spirometry Concepts

The video explains spirometry, a test to assess lung function by measuring air flow and volume. It covers lung anatomy, including the trachea, bronchi, bronchioles, and alveoli, and describes how oxygen and carbon dioxide are exchanged. The video discusses diseases like asthma and emphysema that affect breathing and explains the purpose of spirometry in diagnosing and managing lung conditions. It details the spirometry test procedure, emphasizing correct technique for accurate results.

What is the primary purpose of a spirometry test?

• To measure blood pressure

• To check heart rate

• To evaluate kidney function

• To assess lung function

Which part of the respiratory system is responsible for air passage from the trachea to the alveoli?

• Diaphragm

• Esophagus

• Bronchi and bronchioles

• Larynx

What happens to carbon dioxide in the lungs?

• It remains in the alveoli

• It passes out of the capillaries into an alveolus

• It is converted into oxygen

• It is absorbed into the bloodstream

Which diseases can narrow the bronchioles and reduce air intake?

• Diabetes and hypertension

• Asthma and bronchitis

• Migraine and epilepsy

• Arthritis and osteoporosis

How do lung diseases like emphysema affect the body?

• They increase blood sugar levels

• They improve lung capacity

• They enhance muscle strength

• They damage alveoli, reducing oxygen in the blood

What is a spirometer used for?

• To measure blood glucose

• To check body temperature

• To assess lung function by measuring exhaled air

• To monitor heart rate

What should you do before starting a spirometry test?

• Run for 5 minutes

• Remove dentures if you have them

• Lie down flat

• Drink a glass of water

Why is a nose clip used during the spirometry test?

• To enhance hearing

• To prevent air from escaping through the nostrils

• To improve vision

• To measure blood pressure

How long should an adult exhale during the spirometry test?

• At least 10 seconds

• At least 6 seconds

• At least 1 second

• At least 3 seconds

How many times must the spirometry test be performed to ensure accuracy?

• Once

• Four times

• Twice

• Three times
