1

Movement of gas in and out of alveoli and defined as the maintenance of normal arterial blood carbon dioxide concentration of 35-45 mmHg is known as what?

Normal ventilation

2

What is eupnea?

Normal respiration

3

What is dyspnea?

Difficult or labored breathing.

4

What is tachypnea?

Excessively rapid respiration.

5

What is bradypnea?

Abnormal slowness of breathing.

6

An abnormal breathing pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing is known as what?

Cheyne-Stokes respiration

7

An abnormal pattern of breathing characterized by groups of quick, shallow inspirations followed by regular or irregular periods of apnea is known as what?

Biot's respiration

8

A deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacidosis but also kidney failure is known as what?

Kussmaul breathing

9

An abnormal breathing pattern of breathing characterized by deep, gasping inspiration with a pause at full inspiration followed by a brief, insufficient release is known as what?

Apneustic respiration

10

Air in the lungs can be divided into what 4 different volumes?

- Tidal volume
- Inspiratory reserve volume
- Expiratory reserve volume
Residual volume

11

Air in the lungs can be divided into what 4 different capacities?

- Inspiratory capacity
- Functional residual capacity
- Vital capacity
- Total lung capacity

12

Inspiratory capacity is equal to what?

Tidal volume + Inspiratory reserve volume

13

Functional residual capacity is equal to what?

Expiratory reserve volume + Residual volume

14

Vital capacity is equal to what?

Inspiratory reserve volume + Tidal volume + Expiratory reserve volume

15

Total lung capacity is equal to what?

Inspiratory reserve volume + Tidal volume + Expiratory reserve volume + Residual volume

16

What are 2 things that can be measured with a spirometer?

- Tidal volume
- Vital capacity

17

Minute ventilation is equal to what?

Tidal volume x Respiratory frequency

18

What is the minute ventilation of a patient that has a tidal volume of 250 mL and a respiratory rate of 12 bpm?

3,000 mL/mg

19

What can alter the patient's ability to normally ventilate?

Anesthetic drugs

20

What is required for inhalant anesthetics to be properly taken up and eliminated?

Ventilation

21

What can maintain a smooth and stable plane of anesthesia?

Controlled ventilation

22

What is hypercapnia?

Increased level of CO2.

23

What directly causes vasodilation of peripheral arterioles and myocardial depression?

Hypercapnia

24

Hypercapnia can lead to increased intracranial pressure due to what?

Vasodilation

25

Does hypercapnia directly or indirectly increase circulating catecholamines?

Indirectly

Narcosis progresses with PaCO2 values above what level?

95 mmHg

27

Complete anesthesia is induced at what level?

245 mmHg

28

IPPV stands for what?

Intermittent positive pressure ventilation

29

IMV stands for what?

Intermittent mandatory ventilation

30

PEEP stands for what?

Positive end-expiratory pressure
