Answer 9

Vital capacity

Question 10

What are the 2 respiratory rates

Answer 10

1. Forced expiratory volume 2. Maximum voluntary ventilation

Question 11

Measures how much air a person can exhale during a forced breath in a given time period

Answer 11

Forced expiratory volume

Question 12

Maximum amount of air that can be inhaled and then exhaled in a 12-15 second interval

Answer 12

Maximum voluntary ventilation

Question 13

Increased respiratory rate

Answer 13

hyperventilation

Question 14

hyperventilation may lead to

Answer 14

hypocapnia (low blood CO2 levels)

Question 15

Decreased respiratory rate

Answer 15

Hypoventilation

Question 16

Hypoventilation may lead to

Answer 16

Hypercapnia (high blood CO2 levels which can make blood acidic)

Increased respiratory depth

Answer 17

Hyperpnea

Question 18

difficult/ labored breathing

Answer 18

Dyspnea
