Pulmonary Terminology

Question 1

Dyspnea

Answer 1

difficult/labored breathing

Question 2

Hypercapnia

Answer 2

excess PaCO2 in blood

Question 3

Hyperoxemia

Answer 3

higher than normal O2 in blood

Question 4

Anoxia

Answer 4

lack of O2

Question 5

Apnea

Answer 5

lack of breathing

Question 6

Eupnea

Answer 6

normal breathing at rest

Question 7

Hypoxemia

Answer 7

lower than normal O2 concentration/pressure/saturation in blood

Question 8

Hypocapnia

Answer 8

low PaCO2 in blood

Question 9

Hyperoxia

Answer 9

high O2 concentration/pressure/saturation in lung, blood or tissues

Question 10

Hypopnea

Answer 10

decreased rate and depth of breathing

Question 11

Hyperventilation

Answer 11

increased ventilation in excess of metabolic needs resulting in decreased PaCO2 and increased PaO2

(from increased RR or TV: causing respiratory alkalosis)

Question 12

Hypoxia

Answer 12

low/reduced O2 concentration/pressure/saturation in lung, blood or tissues

Question 13

Hyperpnea

Answer 13

increased rate and depth of breathing in proportion to metabolic rate

Question 14

Hypoventilation

Answer 14

decreased ventilation in regards to metabolic needs resulting in increased PaCO2 & decreased PaO2

(from decreased RR or TV & lead to respiratory acidosis)
