Q

How to do spirometry

A

Spirometry is initially performed, the patient is given an inhaled bronchodilator treatment according to a standard protocol, and then spirometry is repeated. The patient demonstrates a degree of reversibility if the pulmonary function values improve after administration of the bronchodilator

Q

Medical mgt

A

Therapeutic strategies
*promoting smoking cessation as appropriate, providing supplemental oxygen therapy as indicated, prescribing medications, and managing exacerbations.

Some: surgical interventions
Advance copd: palliative care

23
Q

Risk Reduction

A

Modify environmental exposures
*Smoking cessation

24
Q

the single most cost-effective intervention to reduce the risk of developing COPD and to stop its progression

A

Smoking cessation

25
Q

Factors associated with continued smoking

A

strength of the nicotine addiction, continued exposure to smoking associated stimuli (at work or in social settings), stress, depression, and habit

26
Q

promote cessation by

A

“at-risk” message
set a definite “quit date.”
smoking cessation program
Continued reinforcement
Relapses should be analyzed
identify possible solutions

27
Q

a first-line pharmacotherapy that reliably increases long-term smoking abstinence rates—comes in a variety of forms (gum, inhaler, nasal spray, transdermal patch, sublingual tablet, or lozenge

A

Nicotine replacement

28
Q

both antidepressants, may also increase longterm quit rates of smoking

A

Bupropion SR and nortriptyline

29
Q

antihypertensive agent but limited use

A

Clonidine

30
Q

a nicotinic acetylcholine receptor partial agonist, may assist in smoking cessation

A

Varenicline

31
Q

Patients who are not appropriate candidates for pharmacotherapy

A

medical contraindications, light smokers (fewer than 10 cigarettes per day), pregnant women, and adolescent smokers

MAPL

32
Q

is the administration of oxygen at a concentration greater than that found in the environmental atmosphere

A

Oxygen therapy

33
Q

the concentration of oxygen in room air is

A

21%

34
Q

to provide adequate transport of oxygen in the blood while decreasing the work of breathing and reducing stress on the myocardium

A

Oxygen therapy

35
Q

Oxygen transport to tissues depends on factors

A

cardiac output, arterial oxygen content, concentration of hemoglobin, and metabolic requirements

CARM

36
Q

Indications for oxygen therapy

A

change in the patient’s respiratory rate or pattern
*Hypoxia & Hypoxemia

37
Q

a decrease in the arterial oxygen tension in the blood

A

Hypoxemia

38
Q

How Hypoxemia is manifested

A

by changes in mental status, dyspnea, increase in blood pressure, changes in heart rate, arrhythmias, central cyanosis (late sign), diaphoresis, and cool extremities

39
Q

a decrease in oxygen supply to the tissues and cells that can also be caused by problems outside the respiratory system, can be life-threatening.

A

Hypoxia

40
Q

changes occur in the central nervous system because the neurologic centers are very sensitive to oxygen deprivation

A

rapidly developing hypoxia

41
Q

Signs and symptoms of oxygen deprivation

A

depend on how suddenly
resemble that of alcohol intoxication, lack of coordination and impaired judgment.

42
Q

fatigue, drowsiness, apathy, inattentiveness, and delayed reaction time may occur with this kind of hypoxia

A

long-standing hypoxia

43
Q

need for oxygen is assessed by

A

arterial blood gas analysis, pulse oximetry, and clinical evaluation

CAP

44
Q

Complications of oxygen therapy

A

*Oxygen toxicity effects on the lungs and central nervous system or may depress ventilation (lethal adverse effect)
*absorption atelectasis
*Combustion
*Bacterial contamination

CABO

45
Q

is a medication, and except in emergency situations it is given only when prescribed by a health care provider.

A

Oxygen

46
Q

a patient with any type of respiratory disorder is given oxygen therapy only to increase the

A

partial pressure of arterial oxygen (PaO2)
Normal: 60 to 95 mm Hg

47
Q

oxyhemoglobin dissociation curve arterial hemoglobin at these levels is

A

80% to 98% saturated with oxygen

48
Q

higher fraction of inspired oxygen (FiO2) may produce toxic effects on

A

lungs and central nervous system or may depress ventilation (lethal adverse effect)

49
Q

is used to monitor oxygen levels

A

Intermittent or continuous pulse oximetry

50
Q

may occur when too high concentration of oxygen is given for an extended period (generally longer than 24 hours)

A

Oxygen toxicity

51
Q

caused by overproduction of oxygen free radicals, which are by-products of cell metabolism.

A

Oxygen toxicity

52
Q

An additional adverse effect of the administration of high concentrations of
oxygen (greater than 50%) to patients who are sedated and breathing small tidal volumes of air

A

absorption atelectasis

53
Q

It is important to post when oxygen is in use.
