1

condition in which the patient must be in an upright position to breathe

Orthopnea

2

breathlessness

Dyspnea

3

abnormal breath sounds

Adventitious Sounds

4

when auscultating lungs, a high-pitched, short, interrupted crackle sound heard during end of inspiration (not cleared with coughing) CAUSED BY random, sudden inflation of groups of alveoli or a disruptive passage of air through the small airways...most commonlt heard in dependent lobes, right & left lung bases

Crackles

5

when auscultating lungs, a loud, low-pitched, rumbling coarse sound heard either during expiration or inspiration (may be cleared by coughing) CAUSED BY muscular spasm, fluid, or mucus in larger airways, new growth or external pressure...most commonly heard over trachea & bronchi but if loud enough, can be heard over most of lung field

Ronchi

6

when auscultating lungs, a high-pitched, continuous musical sound such as a squeak heard continuously during inspiration or expiration, usually louder on expiration CAUSED BY high velocity airflow through severely narrowed or obstructed airways...most commonly heard all over lung field

Wheezes

7

primary function of the lungs: the movement of air in & out of the lungs

Ventilation

8

primary function of the lungs: the movement of gasses between air spaces & bloodstream

Diffusion

9

the exchange of oxygen & carbon dioxide during cellular metabolism

Respiration

10

the movement of blood into & out of the lungs to the organs & tissues of the body

Perfusion

11

the amount of oxygen entering the the body

Oxygenation

12

inadequate tissue oxygenation with a deficiency in oxygen delivery or oxygen utilization at the cellular level

Hypoxia

13

the abnormal deficiency in the concentration of oxygen in arterial blood, a low partial pressure of oxygen

Hypoxemia

14

condition that occurs when ventilation is inadequate to meet the oxygen demands of the body or to eliminate carbon dioxide

Hypoventilation

15

an increase in the respiratory rate, resulting in excess amount of carbon dioxide elimination

Hyperventilation

16

Factors Affecting Oxygenation

(1) decreased oxygen-carrying capacity (2) decreased inspired oxygen concentration (3) increased metabolic rate (4) conditions affecting chest wall movement

17

collapse of alveoli preventing the normal respiratory exchange of oxygen & carbon dioxide

Atelectasis

18

Condition Affecting Chest Wall Movement

(1) musculoskeletal abnormalities (2) nervous system diseases (3) trauma

19

chemical in the lung that maintains the integrity of the alveoli, keeping them dry & preventing alveolar damage

Surfactant

20

Lifestyle Factors that Affect Cardiopulmonary Function

Nutrition, Hydration, Exercise, Cigarette Smoking, Substance Abuse, Stress

21

Items to Assess During Nursing History of Cardiopulmonary Function

Risk Factors, Fatigue, Pain, Breathing Pattern, Cough, Respiratory Infections, Medication Use

22

bloody sputum

Hemoptysis

23

process that uses the aerosol principle to suspend a maximum number of water drops or particles of the desired size in inspired air...improves clearance

Nebulization

24

a collection of air or other gas in the plueral space

Pneumothorax

25

any muscle that is recruited to increase ventilation by patients with labored breathing

Accessory Muscle

26

small, hollow air sac of the lung

Alveoli

27

temporary cessation of breathing & therefore, the body's intake of oxygen & release of carbon dioxide

Apnea

28

abnormally slow breathing

Bradypnea

29

tubular, hollow breath sounds heard when auscultating over large airways i.e. 2nd & 3rd intercostal spaces

Bronchial Breath Sounds

30

a drug that expands the bronchi by relaxing the bronchial muscle

Bronchodilator
