To understand the phenomenon of Water in the lungsIt’s helpful to know what the pleura is. The pleura is a membrane that surrounds the lungs. It’s composed of the parietal pleura, located against the chest wall, and the visceral pleura, which directly surrounds the lungs. A biological fluid circulates between these two pleurae, lubricating the entire structure and reducing friction between the organs during breathing. Under normal conditions, this fluid is sufficient to allow for proper functioning without causing discomfort. However, several factors can cause an increase in its production, resulting in fluid accumulation that can invade the lungs. Pulmonary alveoliThis buildup limits the amount of oxygen that passes into the bloodstream, affecting the body’s oxygenation and causing respiratory problems.
Diagnosis of water in the lungs
El Water in the lungs It is primarily diagnosed through a physical examination, during which abnormal sounds, such as crackles, are heard in the lungs. These sounds indicate the presence of fluid in the alveoli. To confirm the diagnosis, a chest X-ray is usually performed, which can show areas of the lungs where air has been displaced by the fluid. In some cases, other tests may also be performed, such as echocardiograms, which help identify underlying heart problems that could be causing the edema, as well as blood tests that assess oxygen and carbon dioxide levels.
Symptoms of water in the lungs
People who suffer from pulmonary edema They may experience a variety of symptoms, ranging from mild to extremely severe, depending on the amount of fluid buildup and the speed at which it occurs. Common symptoms include:
- Difficulty breathing, accompanied by noisy or labored breathing.
- Coughing attacks, with or without secretions.
- Chest pain, with a feeling of tightness.
- Discomfort when breathing while lying down.
- Extreme fatigue and lack of energy to carry out daily activities.
- Pale skin and bluish lips (cyanosis), indicating a lack of oxygen in the blood.
Causes of water in the lungs
El Water in the lungs Pulmonary edema can have multiple causes. The main one is heart failure, a condition in which the heart does not pump enough blood to the body. This malfunction causes increased pressure in the blood vessels of the lungs, allowing fluid to leak through the capillary walls and accumulate in the alveoli. However, there are other causes that can also lead to pulmonary edema:
- Lung cancer: Cancer cells can damage blood vessels and increase their permeability, causing fluid buildup.
- Medication: Some drugs, especially those that affect the cardiovascular system, can promote fluid retention in the lungs.
- Exposure to high altitudes: At altitudes above 2400 metres, low atmospheric pressure makes it difficult to oxygenate the blood, which can trigger pulmonary edema.
- Renal insufficiency: By not properly filtering excess fluids and toxins, the kidneys contribute to the accumulation of fluids in the lungs.
- Severe infections: Lung infections such as pneumonia or dengue can trigger inflammation that causes pulmonary edema.
Treatment of water in the lungs
Treatment for fluid in the lungs focuses on relieving breathing difficulties and addressing the underlying cause. To do this, doctors typically begin by administering oxygen through a mask or nasal cannula to improve oxygen saturation. In severe cases, assisted breathing with mechanical ventilators or positive airway pressure devices may be necessary. Depending on the exact cause of the pulmonary edema, various medications may be prescribed.
- Diuretics: These medications, such as furosemide, are given to help the body get rid of excess fluid through urine.
- Vasodilators: They reduce pressure in blood vessels and improve the heart’s ability to pump blood.
- Inotropics: They are used to strengthen heart contractions, especially in people with acute heart failure.
- Morphine: In cases of severe breathing difficulties, morphine can be used to reduce anxiety and shortness of breath, although its use is declining due to its side effects.
If edema is caused by heart problems, such as congestive heart failure, treatment should also include lifestyle changes such as reducing salt in the diet, quitting smoking, and exercising regularly.
Preventing water in the lungs
Starting treatment early is crucial to prevent serious complications from fluid in the lungs. However, once the situation is stabilized, it’s important to identify and treat the underlying cause to prevent future episodes. Some preventive measures include:
- Control blood pressure: Keeping hypertension under control is essential to reduce the risk of heart failure and, therefore, the possibility of developing pulmonary edema.
- Treat infections in time: Any lung or heart infection should be treated immediately to avoid further complications.
- Avoid exposure to high altitudes: For predisposed individuals, it is important to ascend slowly and, if necessary, use oxygen supplements in high altitude areas.
In all cases, following medical advice and having regular checkups are key to preventing the recurrence of pulmonary edema. Fluid in the lungs is a serious condition that affects the breathing capacity of those who suffer from it. While it can be caused by multiple factors, heart failure is the most common cause. Recognizing the symptoms early and seeing a doctor for proper diagnosis and treatment is essential to avoid life-threatening complications such as asphyxiation or systemic organ failure.
