Q

Goals of cardiovascular pulmonary PT

A
  • Prevent airway obstruction/ accumulation of secretions that interfere with normal respiration
  • Improve airway clearance, cough effectiveness, ventilation through mobilization and drainage of secretions

Difficulty with INHALATION
Pulmonary causes:

•atelectasis
•tumor
•pulmonary fibrosis
•pulmonary edema
•PE
•ARDS (adult or acute respiratory distress syndrome caused by fluid build up in the alveoli)
•bronchopulmonary dysplasia (Chronic lung disease of premature babies)
• advanced age
•pneumothorax (A collapsed lung. A pneumothorax occurs when air leaks into the space between the two pleural membranes surrounding each lung, space is called the pleural cavity)
•hemothorax (an accumulation of blood within the pleural cavity- space between the pleural membranes surrounding each lung)
Extrapulmonary causes:
• chest wall pain due to trauma or surgery
•chest wall stiffness due to disease- scleroderma (autoimmune disease- hardening of the skin), ankylosing spondylitis
•postural deformity- scoliosis, kyphosis
• Ventilatory muscle weakness- SCI, CP, MD, Parkinson disease
•pleural disease
• decreased diaphragmatic excursion due to ascites (fluid build up in the abdominal cavity) or obesity

Q

Pulmonary HTN

A

can be caused by a number of factors, all of which force the heart’s right side to work harder to pump blood to the lungs. The right chambers may enlarge as they struggle to function, and the blood is often forced backwards through the tricuspid valve

Q

COPD chronic obstructive pulmonary disease

A
  • peripheral airway disease
  • chronic bronchitis (inflammation (swelling) and irritation of the bronchial tubes. The irritation of the tubes causes mucus to build up)
  • Emphysema (In people with emphysema, the air sacs in the lungs (alveoli) are damaged. Over time, the inner walls of the air sacs weaken and rupture — creating larger often mucus filled air spaces called bullae- instead of many small ones)
  • asthma (marked by spasms in the bronchi of the lungs, causing difficulty in breathing. It usually results from an allergic reaction or other forms of hypersensitivity- airways narrow and swell and may produce extra mucus)
  • bronchiectasis (a condition where the bronchial tubes of your lungs are permanently damaged, widened, and thickened. These damaged air passages allow bacteria and mucus to build up and pool in your lungs- leading to frequent infection and general obstruction)
  • cystic fibrosis (hereditary disease that affects the lungs and digestive system. The body produces thick and sticky mucus that can clog the lungs and obstruct the pancreas)
  • bronchopulmonary dysplasia (Chronic lung disease of premature babies- lungs don’t develop normally)

Q

Types of breathing:

A
  • diaphragmatic
  • segmental: lateral costal expansion and posterior basal expansion
  • pursed lip breathing- avoid forceful expiration- there should be no contraction of abdominals
  • Glossapharyngeal breathing: for high SCI or other neuromuscular disorders- usually ventilator dependent because of absent or incompetent innervation to diaphragm (gulping air)
