- P.845-846 - 22.9 Respiratory adjustments during exercise and at high altitude
- Exercise
- Hyperpnea - increased ventilation in response to metabolic needs
- Different from hyperventilation b/c respiratory changes in
hyperpnea don’t affect blood O2 or Co2 significantly
- Hyperventilation
- Too much ventilation
- Low Pco2 and alkalosis
- High altitude
- Acute motion sickness
- Traveling from normal altitude to high altitude quickly
- Symptoms: headache, breath shortage, nausea, dizziness
- Acclimatization
- Moving from normal altitude to high altitude over long period
- P. 846 - 848: Clinical 22.10 Lung disease
- Chronic Obstructive Pulmonary disease (COPD)
- Emphysema and chronic bronchitis
- Decrease in ability to force air out of lungs
- Dyspnea
- difficult/labored breathing
- Hypoventilation
- Not enough ventilation in relation to metabolic needs
- Emphysema
- Permanent enlargement of alveoli and destruction of alveolar walls
- Lungs lose elasticity
- Chronic bronchitis
- Inhaled irritants lead to chronic production of too much mucus
- Asthma
- Coughing, dyspnea, wheezing and chest tightness - combined or alone
- Tuberculosis
- Infectious disease caused by bacteria
- Spread by coughing and enter body via inhaled air
Document Summary
P. 845-846 - 22. 9 respiratory adjustments during exercise and at high altitude. Hyperpnea - increased ventilation in response to metabolic needs. Different from hyperventilation b/c respiratory changes in hyperpnea don t affect blood o2 or co2 significantly. Traveling from normal altitude to high altitude quickly. Moving from normal altitude to high altitude over long period. P. 846 - 848: clinical 22. 10 lung disease. Decrease in ability to force air out of lungs. Not enough ventilation in relation to metabolic needs. Permanent enlargement of alveoli and destruction of alveolar walls. Inhaled irritants lead to chronic production of too much mucus. Coughing, dyspnea, wheezing and chest tightness - combined or alone. Spread by coughing and enter body via inhaled air. Originates in peripheral lung areas as solitary nodules that develop from bronchial glands and alveolar cells. Comes from epithelium of bronchi or their larger subdivisions and forms masses that hollow out and bleed.
