Do your lungs feel like they're full of water? (Pulmonary Edema) - Let's talk about this!

Do you sometimes feel like you have trouble breathing? Or do you feel like your chest is tight, or do you cough up phlegm and foam? These are not symptoms to just ignore. This could be a condition where your lungs are filled with water, which we medically call Pulmonary Edema . This can be quite serious, so immediate medical attention is needed. Let's talk about this in detail today.

What is Pulmonary Edema?

Simply put, Pulmonary Edema is the accumulation of excess fluid, such as water, in your lungs. Think of it like a sponge. The tiny air sacs inside them absorb oxygen into the blood when we breathe. But if these air sacs fill with water, like a sponge soaked in water, the amount of oxygen that can get into the blood decreases. That's when you experience difficulty breathing, coughing, and chest tightness. This can be life-threatening, so it's important to seek medical attention immediately.

What is High Altitude Pulmonary Edema (HAPE)?

Have you ever climbed a mountain? Or gone to a very high altitude quickly? When you do, some people can develop a condition called High Altitude Pulmonary Edema (HAPE) . This is a severe form of altitude sickness/mountain sickness. The main reason for this is that the oxygen level in the air decreases as you increase in altitude.

When you have HAPE, you may feel tired, weak, have body aches, and have difficulty breathing. You may also experience coughing and chest tightness. Remember, HAPE is a medical emergency. If you experience these symptoms, you should immediately go to a lower altitude and seek medical attention.

What is the difference between Pulmonary Edema and Pneumonia?

Both conditions cause fluid to build up in the lungs. But the cause is different. Pneumonia is caused by an infection. This infection can be caused by viruses, bacteria, or fungi. These organisms cause fluid to fill your air sacs. Pulmonary edema , on the other hand, is not caused by an infection, and the fluid that builds up is usually less thick than in pneumonia, but more watery.

What is the difference between Pulmonary Edema and Pleural Effusion?

This can be a bit confusing. Pleural effusion is a collection of fluid outside the lungs, inside the pleura, the thin membrane that lines the lungs . The pleura is between the lungs and the inner wall of the chest. Normally, there is only a very thin layer of fluid there. Pleural effusion can be caused by conditions such as pneumonia, congestive heart failure, or cancer. Unlike pulmonary edema , the fluid is outside the lungs, which can put pressure on the lungs.

What is Swimming-Induced Pulmonary Edema?

This condition can sometimes occur in competitive swimmers and divers. It is also called (Immersion Pulmonary Edema) . When diving, blood from the legs and abdomen is diverted to the lungs. This extra blood volume increases the pressure in the blood vessels in the lungs. Then, fluid leaks out of those channels and collects in the air sacs. This can damage the lungs.

What are the causes of pulmonary edema?

The causes of fluid in the lungs can be divided into two main categories.

1. Cardiogenic causes

2. Other causes other than heart disease (Noncardiogenic)

1. Causes related to heart disease (Cardiogenic Pulmonary Edema)

Cardiogenic Pulmonary Edema is a condition in which fluid builds up in the lungs due to a problem with the heart. Think of it like a water pump. If the left side of the heart doesn't pump blood properly, the blood gets stuck in the blood vessels in the lungs, like a traffic jam. The pressure in those blood vessels increases, pushing the fluid into the air sacs.

The main heart condition that can cause fluid to fill the lungs in this way is congestive heart failure . In addition, it can also be caused by conditions such as:

• Heart attack.
• Weakened heart muscle (Cardiomyopathy).
• Leaking or narrowing of heart valves (Valvular heart disease).
• High blood pressure (Hypertension).
• Irregular heartbeat (Arrhythmia).
• Myocarditis (inflammation of the heart muscle).
• Pericardial effusion (fluid accumulation in the pericardium, the membrane surrounding the heart).

2. Noncardiogenic Pulmonary Edema (Noncardiogenic Pulmonary Edema)

Noncardiogenic pulmonary edema is a condition in which fluid builds up in the lungs, not due to a heart problem. This occurs when the blood vessels in the lungs become inflamed or damaged. Fluid then leaks out of those blood vessels and collects in the air sacs.

Adult Respiratory Distress Syndrome (ARDS) is another name for this condition (Noncardiogenic Pulmonary Edema) . The main problem in (ARDS) is inflammation. This can be caused by:

• Pneumonia.
• Severe infection (Sepsis).
• Physical injuries (Trauma).
• Pancreatitis.
• Liver disease.
• Some medications.
• Bleeding or swelling in the brain (Neurogenic pulmonary edema).

Additionally, a condition called negative pressure pulmonary edema can occur after an upper airway obstruction. When you try to breathe while there is this obstruction, the blood vessels in the lungs are damaged and fluid leaks out. This is also what happens in High Altitude Pulmonary Edema (HAPE) , which we discussed earlier.

What are the symptoms of Pulmonary Edema?

This condition can occur suddenly (acute) or develop gradually over time (chronic).

Acute pulmonary edema

The symptoms of this appear suddenly.

• Difficulty breathing (dyspnea) , especially when moving around or bending over.
• Bloody or frothy mucus discharge.
• Wheezing is a whistling sound when breathing.
• A feeling of struggling to breathe.
• Feeling like you're suffocating.
• Chest tightness or pain.

Chronic lung inflammation

The symptoms are similar to those of the sudden onset condition, but may be less severe. Other symptoms include:

• Waking up from sleep because of a feeling of suffocation.
• Difficulty breathing increases when lying down.
• Swelling of the legs.
• Feeling very tired and exhausted.

How is Pulmonary Edema diagnosed?

When you see a doctor, he will first do a physical exam to check for fluid in your lungs. He will listen to your heart and lungs with a stethoscope. He will look specifically for:

• An increase or decrease in heart rate or blood pressure.
• Increased respiratory rate.
• Abnormal heart sounds.
• Crackling sounds or wheezing in the lungs.
• Swelling in the body.
• Gray or blue discoloration of the skin.

What are the diagnostic tests?

If your doctor suspects that you have fluid in your lungs, they will order a few more tests. These include:

• Complete Blood Count (CBC).
• Blood chemistries.
• Pulse oximetry test to check blood oxygen levels.
• A chest X-ray to see if there is fluid in the lungs.
• An echocardiogram, an ultrasound of the heart, is performed to check for any abnormal heart function.
• An Electrocardiogram (EKG) to check for heart rhythm problems or a heart attack.
• A test called cardiac catheterization to check for blockages in the coronary arteries of the heart.

How is Pulmonary Edema treated?

Pulmonary Edema is a serious condition. If you develop this condition suddenly (acutely), you need immediate treatment. You may need to be treated in the Emergency Department (ETU) or Intensive Care Unit (ICU) .

Here are some treatment options:

• Providing oxygen through small tubes (prongs) placed in the nose.
• The use of machines that blow air into the lungs through a mask worn on the face.
• The use of ventilators or respirators that blow air through a tube inserted into the trachea.
• Medicines that increase urination to remove fluid or medicines that strengthen the heart.
• If the pulmonary edema is not caused by congestive heart failure, other medications such as antibiotics and steroids may be prescribed.

How can I prevent pulmonary edema?

If you are at increased risk for pulmonary edema, you can take several steps to take care of yourself.

• If you have a heart condition, take your medications exactly as prescribed by your doctor.
• Get regular vaccinations.
• See your doctor often, especially if you have difficulty breathing.
• Eat a healthy, low-salt diet.
• Do not smoke.
• Maintain a healthy weight.
• If you are planning activities that could cause lung swelling, such as hiking, talk to your doctor about it.

When should I go to the Emergency Department (ETU) ?

Acute lung injury can be life-threatening. If you have any of these symptoms, call 911 or go to the nearest emergency room immediately:

• Severe difficulty breathing.
• Feeling like you're suffocating.
• Shortness of breath.
• Coughing up blood or blood-tinged frothy mucus.
• A whistling sound or a feeling of struggling to breathe.
• Rapid heartbeat.
• Feeling restless or agitated.
• Blue or gray discoloration of the skin.
• Excessive sweating.
• Dizziness or weakness.

Important: Pulmonary Edema is a serious medical condition. If you develop this condition suddenly, you need to seek immediate treatment. The chances of recovery from this condition depend on the cause of the condition, the severity of the condition, and how quickly you seek treatment. The sooner you get treatment, the better your chances of recovery.

How long can this condition last? Or could it lead to sudden death?

How long you can live with this condition depends on the cause of the condition and how quickly you get treatment. If you have acute pneumonia, you need treatment right away. In severe cases, it can be life-threatening if not treated quickly. Therefore, hospitalization is often necessary, especially in emergency situations.

Finally, things to remember (Take-Home Message)
