Clinical Pearls in Pulmonology
Clinical Pearls in Pulmonology :
► Patients with obstructive lung disease have trouble blowing air out (reduced FEV1/FVC), whereas patients with restrictive lung disease have trouble getting air in (reduced TLC).
► The mainstay for treatment of chronic obstructive pulmonary disease exacerbations includes bronchodilators, oxygen, and glucocorticoids, as well as antibiotics if infection is suspected.
► Controlled supplemental oxygen along with positive-pressure mask ventilation (biphasic positive airway pressure) may prevent respiratory failure requiring intubation.
► Smoking cessation and supplemental oxygen to treat chronic hypoxemia are the only medical therapies shown to decrease mortality among persons with chronic obstructive pulmonary disease.
► The hallmark of restrictive lung disease is decreased lung capacities, particularly the TLC but also the FVC.
► Whereas in obstructive and restrictive lung disease, the FEV1 is decreased, the FEV1/FVC is decreased in obstructive processes and normal in restrictive processes.

Chest Pain Clinical Pearl
Always think about "P"
Pneumothorax
Pneumonia
Pleurisy (Pleuritis)
Pulmonary embolism
Pericarditis
[If a disease presented to you with Pleuritic Pain, Think about P-above |MI Pain is NOT Pleuritic]
Clinical Pearl: Antibiotics for Anaerobes
Above the diaphragm anaerobes = Clindamycin
Below the diaphragm anaerobes = Metronidazole
