what age group does rheumatic fever commonly effect.

5-15 years .

Bronchiectasis

- Abnormal dilation of the medium bronchi occur - frequent obstructions occur in the airway damaging elastic fibers in bronchial wall - causes fibrous adhesion's which pull the wall of bronchus out. pooling of fluid occurs and is infected with pathogens - additional infection causes further damage and fibrosis to the lungs

excess fluid in the alveolar tissue may develop when....

- Inflammation is present in the lungs ( increased capilary permeability - plasma protein levels are low - pulmonary hypertension develops - blocked lymphatic drainage

Tertalogy of Fallot 4 defects

- 4 defects are the pulmonary valve stenosis, Ventricular septal defect, dextroposition of the aorta, and right ventricular hypertrophy

regular rapid heart rate 100-160

Shock

results from a decreased circulation blood volume, leading to decreased tissue perfusion and general hypoxia.

chronic low grade but damaging inflammation of the lungs over a long period of time.

second group of restrictive lung disease.

S/S decompensated

Pulsus Paradoxus

systolic b/p drops 10mmhg during inspiration.

afterload

the force required to eject blood from the ventricles. - it is determined by peripheral resistance to the opening of the pulmonary semilunar valves.

malignant hypertension

the third type of hypertension - uncontrollable when treated with 3 or more drugs. - Diastolic Pressure is often very high.

how do dissecting aneurysms form

through a tear in the intima

expressive aphasia

unable to speak or write fluently

Sinusitis

usually a secondary bacterial infection to a cold or allergy. Causes obstructed drainage of the paranasal sinus.

flail chest

usually results from fractures of 3-6 ribs in two or more places. OR sternum fracture and a number of consecutive ribs.
