Q

crackles

A

frequently heard on inspiration, are soft, high pitched discontinuous (intermittent) popping sounds; they are produced by air passing through fluid in airways

18
Q

dyspnea

A

difficulty breathing

19
Q

dysrhythmia

A

a disturbance of the rate or rhythm of the heart; also known as arrythmia

20
Q

electrocardiogram (ECG)

A

electrodes attached to the skin can detect the hearts electrical currents and transmit them to this instrument that produces a record

21
Q

expiration

A

exhalation; the passive phase, is the movement of air out of the lungs

22
Q

hyperventilation

A

increased rate an depth of ventilation, above the body’s normal metabolic requirements

23
Q

hypoventilation

A

decreased rate or depth of air movement into the lungs

24
Q

hypoxemia

A

insufficient oxygen in the blood

25
Q

hypoxia

A

a condition in which an inadequate amount of oxygen is available to cells

26
Q

inspiration

A

inhalation; the active phase, involves movement of muscles and the thorax to bring air into the lungs

27
Q

internal respiration

A

the exchange of oxygen and carbon dioxide between the circulating blood and tissue cells

28
Q

ischemia

A

decreased oxygen supply to the heart caused by insufficient blood supply

29
Q

myocardial infarction

A

one type of acute coronary syndrome characterized by the death of heart tissue due to lack of oxygen

30
Q

oxygenation

A

the process of providing life-sustaining oxygen to the body’s cells

31
Q

perfusion

A

the process by which oxygenated capillary blood passes through body tissues

32
Q

pulmonary ventilation

A

the movement of air into and out of the lungs

33
Q

pulse oximetry

A

a noninvasive technique that measures the peripheral arterial oxyhemoglobin saturation of arterial blood

34
Q

respiration

A

involves gas exchange between the atmospheric air in the alveoli and blood in the capillaries

35
Q

sinoatrial (SA) node

A

a mass of tissue in the upper right atrium, just below the opening of the superior vena cava; this node initiates the transmission of electrical impulses causing contraction of the heart at regular intervals (pacemaker)

36
Q

spirometer

A

an instrument that measures lung volumes and airflow

37
Q

sputum

A

the respiratory secretion expelled by coughing or clearing the throat

38
Q

surfactant

A

a detergent-like phospholipid, reduces the surface tension between the moist membranes of the alveoli, preventing their collapse

39
Q

tachypnea

A

rapid breathing

40
Q

tracheostomy

A

an artificial opening made into the trachea, usually at the level of the second or third cartilaginous ring

41
Q

tracheostomy tube

A

a curved tube inserted through the opening

42
Q

ventricles

A

the lower chambers of the heart; force blood out of the heart through the left and right pulmonary arteries and the aorta

43
Q

vesicular

A

low-pitched, soft sounds heard over peripheral lung fields

44
Q

wheezes

A

continuous musical sounds, produces as air passes through airways constricted by swelling, narrowing, secretions, or tumors
