First aid for swelling of the feet
What is pulmonary edema?
Pulmonary edema is a congestion in the pulmonary vesicles (alveoli) and in the tissues of the lungs watery fluid. This condition can occur in the following cases:
- with heart failure (as a result of blood stagnation in the lungs)
- with a sudden increase in pressure
- with acute inflammation of the kidneys, uremia (when the fluid is not excreted from the body)
- with inflammatory or toxic damage of the vessels of the lungs
- for drowning
- with excessive physical exertion in the cold (when blood from the periphery accumulates in the center and in the pulmonary veins)
Signs of pulmonary edema: choking, loud wheezing, bubbling breath, coughing, pink foam discharge from the mouth, sharp pallor of the skin with a cyanotic shade; the pulse is frequent, weak. With a strong edema a person loses the creature and dies from lack of oxygen.
First aid for swelling of the lungs
In a hospital (or when an ambulance arrives), a person withacute lung edema is sucked off the foam from the respiratory tract by means of a catheter, injected with a drug to improve blood circulation, and make artificial ventilation of the lungs with a high oxygen content.
But how can you save a person with a rapidly developing pulmonary edema before an ambulance arrives?
If the person is conscious - he needs to be brought to a semi-sitting position, so that the blood flows slightly from the lungs.
It is necessary to give the patient from the medicine cabinet under the tongue a tabletnitroglycerin to its full resorption just under the tongue. Nitroglycerin lowers blood pressure, relaxes the smooth muscles of blood vessels. In the absence of effect, the next tablet should be offered no earlier than 5-10 minutes, but not more than 6 tablets per day.
In addition, diuretics can help, through the release of fluid from the body.
To cause the outflow of blood from the lungs to the periphery, lower the patient's legs into a basin with hot water, or wrap them with a cloth moistened with hot water.
If within half an hour the pulmonary edema does not disappear, moisten gauze with alcohol or vodka and let the patient breathe through it. Alcohol is one of the effective anti-foam agents.
