Q

Embolus

A

A blood clot or other substance in the circulatory system that travels to a blood vessel where it causes a blockage of bloodflow.

21
Q

Emphysema

A

A sisease of the lungs in which ther is extreme dilation and eventual destruction of the pulmonary alveoli with poor exchange of oxygen and carbon dioxide; it is one form of chronic obstructive pulmonary disease.

22
Q

Epiglottitis

A

A bacterial infection in which the epiglottis becomes inflamed and enlarged and may cause an upper airway obstruction.

23
Q

Hay fever

A

An allergic response, usually to outdoor airborne allergens such as pollen or sometimes indoor allergens such as dust mites or pet dander; also called allergic rhinitis.

24
Q

Hyperventilation

A

Rapid, usually deep, breathing that lowers the blood carbon dioxide level below normal.

25
Q

Hyperventilation syndrome

A

This syndrome occurs in the absence of physical problems. The respirations of a person who is experiencing hyperventilation syndrome may be as high as 40 shallow breaths/min or as low as 20 very deep breaths/min. This syndrome is often associated with panic attacks.

26
Q

Hypoxia

A

A dangerous condition in which the body tissues and cells do not have enough oxygen.

27
Q

Hypoxic drive

A

A condition in which chronically low levels of oxygen in the blood stimulate the respiratory drive; seen in patients with chronic lung diseases.

28
Q

Influenza type A

A

Virus that has crossed the animal/human barrier and has infected humans, recently reaching pandemic level with the H1N1 strain.

29
Q

Metered-dose inhaler (MDI)

A

A miniature spray canister used to direct medications through the mouth and into the lungs.

30
Q

Orthopnea

A

Severe dyspnea experienced when lying down and relieved by sitting up.

31
Q

Oxygenation

A

The process of delivering oxygen to the blood by diffusion from the alveoli following inhalation into the lungs.

32
Q

Pandemic

A

An outbreak that occurs on a global scale.

33
Q

Parosysmal nocturnal dyspnea

A

Severe shortness of breath, especially at night after several hours of reclining; the person is foced to sit up to breathe.

34
Q

Pertussis (whooping cough)

A

An airborne bacterial infection that affects mostly children younger than 6 years. Patients will be feverish and exhibit a “whoop” sound on inspiration after a coughing attack; highly contagious through droplet infection.

35
Q

Pleural effusion

A

A collection of fluid between the lung and chest wall that may compress the lung.

36
Q

Pleuritic chest pain

A

Sharp, stabbing pain in the chest that is worsened by a deep breath ro other chest wall movement; often caused by inflammation or irritation of the pleura.

37
Q

Pneumonia

A

An infectious disease of the lung that damages lung tissue.

38
Q

Pneumothorax

A

An accumulation of air or gas in the pleural cavity.

39
Q

Pulmonary edema

A

A buildup of the fluid in the lungs, often as a result of congestive heart failure.

40
Q

Pulmonary embolism

A

A blood clot that breaks off from a large vein and travels to the blood vessels of the lung, causing obstruction of blood flow.

41
Q

Respiration

A

The process of exchanging oxygen and carbon dioxide.

42
Q

Respiratory cyncytial virus (RSV)

A

A virus that causes an infection of the lungs and breathing passages; can lead to other serious illnesses tht affect the lungs or heart, such as bronchiolitis and pneumonia. RSV is highly contagious and spreads through droplets.

43
Q

Ronchi

A

Coarse, low-pitched breath sounds heard in patients with chronic mucus in the upper airways.

44
Q

Small-volume nebulizer

A

A respiratory device that holds liquid medicine that is turned into a fin mist. The patient inhalses the medication into the airways and lungs as a treatment for conditions such as asthma.

45
Q

Stridor

A

A harsh, high-pitched respiratory sound, generally heard during inspiration, that is caused by partial blockage or narrowing of the upper airway; may be audible without a stethoscope.

46
Q

Tuberculosis (TB)

A

A contagious disease that attacks the lungs and that can remain dormant in a persons lungs for decades, then reactivate; many strains are resistant to antibiotics. TB is spread by cough.

47
Q

Ventilation

A

The exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person, such as an EMT.

48
Q

Vesicular breath sounds

A

Normal breath sounds made by air moving in and out of the alveoli

49
Q

Wheezing

A

A high-pitched, whistling breath sound that is most prominent on expiration, and which suggests an obstruction or narrowing of the lower airways; occurs in asthma and bronchiolitis.
