what would you expect the ABG of a patient with COPD (C-O-P-D)
increased paCO2
increased HCO3
decreased PH (acidosis)
over time the body compensates by increasing HCO3 reabsorption thus the presentation = RESPIRATORY ACIDOSIS with METABOLIC compensation
what type of bacteria is TB?
acid-fast bacillus
rod shaped
aerobic
what does TB infection look like on a chest x-ray?
upper lobe infiltrate/cavitation and hilar lymph-adeno-pathy
what is the treatment for TB
2 months: rifampin, isoniazid, pyrazinamide and ethanbutol
4 months: rifampin and isoniazid
what is the classic presentation of pulmonary TB
chronic cough
fatigue, night sweats, weight loss
possibly hemoptysis
what is the typical presentation of a pulmonary embolism (PE)?
sudden onset hypoxemia (low o2)
tachycardia
pleuritic chest pain
possibly hemoptysis
what is the typical ECG presentation of a PE?
S1Q3T3
greater S wave deflection in lead 1
Q wave in lead 3
downwards T wave in lead 3
risk factors for PE
active cancer
taking the COCP
immobility /(long haul flights/surgery)
