Atrioventricular Bundle

A

a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles, causing them to contract

Q

Atrioventricular (AV) Node

A

a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to the atrioventricular bundle

Q

Dyspnea

A

difficult or labored breathing

20
Q

Dysrhythmia

A

an abnormal cardiac rhythm

21
Q

Electrocardiogram (ECG)

A

graphic record produced by the electrocardiograph

22
Q

Endotracheal Tube

A

polyvinyl-chloride airway that is inserted through the nose or the mouth into the trachea, using a laryngoscope as a guide

23
Q

Expiration

A

act of breathing out; synonym for exhalation

24
Q

Hyperventilation

A

condition in which there is more than the normal amount of air entering and leaving the lungs

25
Q

Hypoventilation

A

decreased rate or depth of air movement into the lungs

26
Q

Hypoxemia

A

deficient oxygenation of blood

27
Q

Hypoxia

A

Inadequate amount of oxygen available to the cells

28
Q

Inspiration

A

act of breathing in

29
Q

Internal Respiration

A

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

30
Q

Ischemia

A

deficiency of blood in a particular area

31
Q

Nasal Cannula

A

disposable, plastic device that delivers oxygen via two protruding prongs for insertion into the nostrils

32
Q

Oxygenation

A

process of providing cells life-sustaining oxygen

33
Q

Perfusion

A

process by which oxygenated blood passes through body tissues

34
Q

Pulmonary Ventilation

A

movement of air into and out of the lungs

35
Q

Pulse Oximetry

A

noninvasive techniquethat measures the oxygen saturation (SaO2) of arterial blood

36
Q

Respiration

A

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

37
Q

Sinoatrial (SA) Node

A

a mass of tissue in the upper right atrium, just below the opening of the superior vena cava, that initiates the transmission of electrical impulses, causing contraction of the heart at regular intervals; also known as pacemaker

38
Q

Spirometer

A

instrument used to measure lung capacities and volumes; one type is used to encourage deep breathing (incentive spirometry)

39
Q

Sputum

A

respiratory secretion expelled by coughing or cleaning the throat

40
Q

Surfactant

A

detergent-like phospholipid that reduces surface tension of the fluid lining the alveoli

41
Q

Tachypnea

A

rapid rate of breathing

42
Q

Tracheostomy

A

artificial opening made in the trachea through which a tracheostomy tube is inserted

43
Q

Ventricles

A

lower chambers of the heart

44
Q

Vesicular

A

normal sound of respirations heard on auscultation over peripheral lung areas

45
Q

Wheezes

A

Continuous, high-pitched squeak or musical sound made as air moves through narrowed or partially obstructed airway passages
