21
Q

· forced vital capacity

A

Volume of air remaining in the lung after maximal inspiration.

22
Q

· hyperventilation

A

An increase in the rate and depth of breathing that leads to excessive loss of carbon dioxide from the blood.

23
Q

· hypoventilation

A

Shallow breathing with a lower than expected respiratory rate.

24
Q

· hypoxemia

A

Low amount of oxygen in the blood.

25
Q

· hypoxia

A

Below the expected level of oxygen in body tissue.

26
Q

· inspiratory reserve volume

A

Volume of air breathed in after a typical inspiration.

27
Q

· lung compliance

A

The point to which a lung can expand in response to increased pressure within the alveoli (interalveolar).

28
Q

· perfusion

A

The flow of blood by the cardiopulmonary system into the alveolar capillaries where deoxygenated blood is exchanged for oxygenated blood in the heart and delivered to the rest of the body.

29
Q

· pleura

A

A protective layer or membrane covering the lungs.

30
Q

· pleural cavity

A

The space or cavity between the visceral and parietal layers of the lung.

31
Q

· pleural effusion

A

A buildup of fluid in the pleural space.

32
Q

· pneumothorax

A

Air in the pleural space causing the lung to completely or partially collapse.

33
Q

· preload

A

The blood remaining in the left ventricle at the end of diastole causing it to stretch.

34
Q

· pulmonary circulation

A

The movement of blood from the heart to the lungs from the capillaries for gas exchange and back.

35
Q

· regurgitation

A

Leaking heart valves that do not close (CDC).

36
Q

· residual volume

A

Volume of air remaining in the alveoli after expiration.

37
Q

· respirations

A

The amount of breaths per minute.

38
Q

· rhonchi

A

Obstruction of the airway that sounds like rattling.

39
Q

· sinoatrial (SA) node

A

The pacemaker of the heart.

40
Q

· stenosis

A

Narrowing of a heart valve.

41
Q

· stridor

A

Narrowing of the airway heard on inhalation that sounds like music or whistling.

42
Q

· stroke volume

A

Volume of blood ejected by the left ventricle during one contraction.

43
Q

· surfactant

A

A lubricant made in the lungs to keep the alveoli from collapsing during exhalation.

44
Q

· systole

A

The contraction phase of the cardiac cycle when the mitral and tricuspid valves close and blood is ejected into the aorta and pulmonary arteries.

45
Q

· tachycardia

A

Heart rate above the expected reference range.

46
Q

· tactile fremitus

A

A vibration felt in the chest wall during palpation or auscultation found when speaking.

47
Q

· tidal volume

A

Volume of air inspired and expired with each breath.

48
Q

· total lung capacity

A

Volume of air remaining in the lung after maximal inspiration.

49
Q

· tripod position

A

Placement of the arms against the legs or examination table while seated.

50
Q

A

The flow of air inside or outside of the alveoli.

51
Q

· vital capacity

A

Maximum volume of air that is expelled after maximal inspiration.

52
Q

· wheezing

A

A high
