Pink foamy phlegm

Introduction For some reason, the formation of tissue fluid in the lung and the balance of reflux are imbalanced, so that a large amount of tissue fluid can not be absorbed by the pulmonary lymph and pulmonary vein system in a short time, and it is extravasated from the pulmonary capillaries and accumulates in the alveolar, interstitial and bronchioles. , resulting in severe ventilation and ventilation function, clinical manifestations of extreme dyspnea, sitting breathing, cyanosis, sweating, paroxysmal cough with a lot of white or pink foam sputum.

Cause

The left and right heart's blood output is relatively balanced, but in some pathological conditions, such as the return of blood volume and right heart discharge increased sharply or the left heart discharge suddenly decreased severely, causing a large amount of blood to accumulate in the pulmonary circulation, making the pulmonary capillaries The venous pressure rises sharply. When it rises above the colloidal osmotic pressure of the pulmonary capillaries, on the one hand, the hemodynamics in the capillary changes, on the other hand, the pulmonary circulation is congested, the permeability of the pulmonary capillary wall is increased, and the liquid is filtered through the capillary wall to form the lung. Edema. Clinically, acute pulmonary edema caused by hypertensive heart disease, coronary heart disease and rheumatic valvular heart disease accounts for the vast majority of cardiogenic pulmonary edema.

1. Laboratory tests: including blood and urine routine, liver and kidney function, cardiac zymogram and electrolyte examination, provide clues for diagnosis of infection, hypoproteinemia, kidney disease and heart disease.

2, arterial blood gas analysis: oxygen partial pressure in the early stage of the disease mainly showed hypoxia, oxygen can make PaO2 significantly increased. The partial pressure of carbon dioxide is mainly characterized by low CO2 in the early stage of the disease, high CO2 in the later stage, respiratory acidosis and metabolic acidosis.

3, X-ray examination: only when the extra-pulmonary fluid volume increased by more than 30%, the chest X-ray examination showed abnormal shadows. The X-ray manifestations of interstitial phase were mainly due to blurred and increased pulmonary vascular texture, unclear hilar shadow, decreased lung translucency, and widened pulmonary lobule spacing.

Differential diagnosis

Differential diagnosis

1, cough chocolate color : reddish brown or chocolate color , found in the amoebic liver abscess into the lung caused by lung amebiasis.

2, yellow or green sticky: suggesting a purulent infection in the respiratory tract, green sputum often caused by bile, degenerative hemoglobin or pyocyanin, found in jaundice, slow absorption of pneumococcal pneumonia, Pseudomonas aeruginosa infection.

3, bloody sputum: seen in lung cancer, tuberculosis, bronchiectasis.

4, rust color : seen in pneumococcal pneumonia.

5, pink or bloody foam : see acute pulmonary edema.

6, jam-like sputum: seen in paragonimiasis, gray or black sputum, found in a variety of pneumoconiosis, such as coal pneumoconiosis.

7, brown sputum: seen in the pulmonary infarction, the lungs contain iron and blood yellowing.
