-
Consists of the mouth and nasal cavity and passages, pharynx and trachea, which collectively connect the respiratory zone of the lungs to the atmospheric air surrounding the body.
Conducting Zone
-
Consists of the respiratory bronchiles and alveoli ducts and alveoli, which collectively represent the sites of pulmonary gas exchange.
Respiratory Zone
-
What are the causes of pulmonary disease?
Genetic causes, environment, or smoking
-
Poor gas exchange between ambient air and pulmonary capillary blood.
Pulmonary disease
-
COPD causes a ___ in VO2 max.
reduction
-
What are the 2 main categories of pulmonary disease?
COPD and Restrictive lung diseases
-
COPD causes a?
reduction in airflow, and SOB in exertion.
-
What happend during chronic bronchitis?
persistant sputum production caused by thickened bronchial wall and excess secretions.
-
What happens during bronchial asthma?
bronchial smooth muscle contraction and airway restrictions
-
What is Emphysema?
- Loss of elastic recoil of alveoli and bronchioles
- enlargment of alveoli and bronchioles
- airways can collapse diring exhalation
-
What happens during asthma attack?
airway restriction and smooth muscle contraction
-
Treatment for asthma?
Bronchodilators
-
Asthma affects ___ Americans.
14.6 MILLION
-
Causes of asthma?
Allergic reaction to dust, pollen, smoke, pollution, exercise, or viral infections
-
Exercise induced Asthma causes ___ to restrict.
bronchioles
-
what test is used to test for EIA? And what results show positive?
- FEV1 test
- if there is a 15% reduction after exercise compared to pretest values
-
What is Cystic Fibrosis?
- A type of COPD
- Recessivley inherited genetic disorder.
- Affects 1 in 2500 caucasian kids
- thick mucus blocks air exchange
- aerobic exercise helps clear lungs
- percussion of lungs helpful
-
Restrictive lung disease is caused by?
- kyphoscoliosis
- pectus excavatum
- coal dust
- asbetosis
- chemotherapy
- radiation therapy
- obesity
- pregnancy
-
What is Restricive lung disease?
air does not get trapped but a reduced amount is taken in. so there is an incresed work in breathing.
-
Total volume of air in lungs
total lung capacity
-
the max volume of air that can be exhaled from lungs in one expiratory volume
vital capacity
-
the volume of air remaining in lungs after forced max exhalation
residual volume
-
the amount of air remininf in lungs after you conpleted a respiratory cycle
inspired capacity
-
volume of air in lungs after normal expiration
functional residual capacity
-
volume of air ventilated into and out of lungs with each breath, (aka normal breathing)
tidal volume
-
Max volume of air that can be moved in 1 second.
FEV1 (forced exiratory volume)
-
the volume of air that can be breathed when going fron mas inhalation to max exhalation
VC (vital capacity)
-
What is Obstructive lung disease ?
- less than 80% capacity of FEV1
- air is taken in but trapped
- increased dead space
-
Exercise for people with COPD has little effect on VO2max, lung function, or mortality rate.
What are benefits?
- improve functional capacity
- better quality of life
- dyspnea relief
-
exercise presciption for pulmonary patients
- rhythmic dynamic exercise
- 3-5 times a week
- at leat 30 min a session
- resistance training recommended
-
what is hypoxemia?
decreased arterial oxygen content
-
When SaO2 values are below 90%?
O2 supplementation is needed.
-
Exercise Rx for COPD
Mode
Aerobic
-
Exercise Rx for COPD
Frequency
3-5 days/week
-
Exercise Rx for COPD
Intensity
- mild-moderate- @ aerobic threshold on noticable dyspnea
- severe- symptoms of dyspnea are guiding factor
-
Exercise Rx for COPD
Duration
10-30 min
-
Supplemental O2 to keep SaO2 level above ___%. is consideration for pulmonary disease.
90
-
Pursed lip breathing is considered for patients with___.
Emphysema
-
Bronchodilators treat ___.
asthma and COPD(bronchitis)
-
what do bronchodialtors do?
inhibit bronchial smooth muscle constriction
-
Bronchodilators at rest might?
- increase Hr
- Arrhythmias
- BP
-
Bronchodilators during exercise might?
- increase HR. BP Pvc's
- Arrythmias
- increase capacity for patients with asthma and COPD
