CT Pulmonary angiogram
bibasilar subsegmental atelectric changes is noted in both lung bases
Single Portable Chest X-Ray
bibsilar atelectectasis hypoventilation, neumoperitoneum is seen
Acute Abdominal Series
right basilar atelectatis, rounded densities are seen in the RUQ which may represent fecal content vs gallstones, probable post op ileus
PA & Lateral Chest
pneumoperitoneum, bibasilar atelectasis
What is the pathophysiology of Asthma Exacerbation
look at chain linking game
what mediators do the mast cell release? (5)
- seratonin
- chemotactic factors
- inflamation
- histamine
- leukotrines
When leukotrienes are released what do they do? (2)
- increase vascular permeability. which causes edema. which we will se in the lower extremities
- cause brachial smooth muscle spasms
what chemotactic factors are released? (3)
- eosinophils
- platelets
- neutrophils
