Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .
Acute bronchitis, also known as a chest cold, is short-term bronchitis – inflammation of the bronchi (large and medium-sized airways) of the lungs. [2] [1] The most common symptom is a cough.

An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. [ 3 ] [ 4 ] This commonly includes nasal obstruction, sore throat, tonsillitis , pharyngitis , laryngitis , sinusitis , otitis media , and the common cold .
Typical infections of the upper respiratory tract include tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, certain influenza types, and the common cold. [3] Symptoms of URIs can include cough , sore throat , runny nose , nasal congestion , headache , low-grade fever , facial pressure, and sneezing .
Patients may watch for symptoms, such as shortness of breath, change in character or amount of mucus, and start self-treatment as discussed with a health care provider. This allows for treatment right away until a doctor can be seen. [5] The symptoms of acute exacerbations are treated using short-acting bronchodilators.
Auscultation shows crackles or wheezing. Oxygen saturation usually shows hypoxemia. In most cases chest radiological examination shows signs of pulmonary edema, but a significant minority have a normal initial chest X-Ray. [3] Rapid resolution of initial signs and symptoms within 48 hours is typical.
