DIAGNOSTIC EXAM

Question 1

• ABG analysis (reveals hypoxemia, hypocapnia)

Answer 1

BRONCHIAL ASTHMA

Question 2

ABG analysis reveals arterial hypoxemia, hypocapnia
Incentive Spirometry results decrease PEFR, timed FEV1, increase residual volume (air trapping in lungs), forced VC, increase FRC, and increase TLC
others: allergy skin test, IgE test

Answer 2

BRCAHIAL ASTHMA

Question 3

ABG analysis reveals arterial hypoxemia, hypocapnia (indication of massive PE), and severe respiratory alkalosis.
Pulmonary angiography is a definitive diagnosis, gold standard, most sensitive, and most specific test of pulmonary embolism because it can visualize pulmonary vasculature.
Spiral CT scan is most frequently used diagnostic test to identify embolism in pulmonary vascular tree.
VQ lung scan is a lung scan using radioactive isotopes to visualize pulmonary microvasculature and distant pulmonary flow obstruction.
Increase LDH3 (lactate dehydrogenase isomerase) indicates lung tissue injury.

Answer 3

PULMONARY EMBOLISM
