Pulmonary Terminology

Question 1

Anoxia

Answer 1

Lack or absence of oxygen

Question 2

Apnea

Answer 2

No breathing

Question 3

Dyspnea

Answer 3

Difficult or labored breathing; due to decreased ventilatory capacity and increased work of breathing

Question 4

Eupnea

Answer 4

Normal breathing at rest

Question 5

Hypercapnia (Hypercarbia)

Answer 5

Excess PaCO2 in blood possibly from hypoventilation or diffuse bronchopulmonary disease

Question 6

Hypocapnia (Hypocarbia)

Answer 6

Low PaCO2 in blood possibly from hypervenilation

Question 7

Hyperoxia

Answer 7

High O2 concentration, pressure, or saturation in lung, blood, or tissues

Question 8

Hypoxia

Answer 8

Low or reduced O2 concentration, pressure, or saturation in lung, blood, or tissues

Question 9

Hyperoxemia

Answer 9

Higher than normal P(o2) in blood

Question 10

Hypoxemia

Answer 10

Lower than normal O2 concentration or pressure or saturation in the blood

Question 11

Hyperapnea

Answer 11

Increase in rate and depth of breathing in proportion to metabolic rate

Question 12

Hypoapnea

Answer 12

Decrease in rate and depth of breathing compared to breathing at rest

Question 13

Hypoventilation

Answer 13

Decreased ventilation in regards to metabolic needs resulting in increased PaCO2 (hypercapnia) and decreased PaO2 (hypoxemia). May be result of decreased respiratory rate and/or tidal volume and may lead to respiratory acidosis

Question 14

Hyperventilation

Answer 14

Increased ventilation in excess of metabolic needs resulting in decreased PaCO2 (hypocapnia) and increased PaO2 (hyperoxemia). May be result of increased respiratory rate and/or tidal volume. Produces signs/sx of dizziness, numbness, tingling, and may lead to respiratory alkalosis
