![]() This may be a bacterial or viral infection. ![]() In adults, mycoplasma can rarely result in bronchiolitis without giving pneumonia. Pneumonia is an inflammation of the lung tissue caused by an infection. ![]() Patients who have difficulty breathing, who are confused, or. Occasionally, chest x-ray shows increased interstitial markings consistent. Physical examination may reveal fever or sometimes low body temperature, an increased respiratory rate, low blood pressure, a fast heart rate, or a low oxygen saturation, which is the amount of oxygen in the blood as indicated by either pulse oximetry or blood gas analysis. It may account for 10-15 of community-acquired pneumonia in adults. In bronchitis, the x-ray will show no evidence of lung infiltrates or consolidation. The term consolidation is often erroneously used as a synonym for pneumonia. It is relatively common in the pediatric population where it is considered the most common community-acquired pneumonia in 5 to 20-year-olds (may account for 40 of such cases 7). Similarly, chest CT can help rule out pneumonia in patients with only moderate suspicion for pneumonia but nondiagnostic chest radiographs. The term atypical pneumonia is applied to non-lobar patchy or interstitial infiltrates on chest x-ray The causative organism is not identified on gram stain. Usually, acute bronchitis should not be treated with antibiotics, as it is often of viral etiology and thus. In selected cases, if clinical suspicion for CAP is high but chest imaging is negative, we obtain a chest computed tomography (CT). Pneumonia is in contrast to pneumonitis, which is inflammation of the pulmonary interstitium. Of note, some of the interstitial lung diseases are termed pneumonia rather than pneumonitis. LRTIs include acute bronchitis and pneumonia.
