Are your lungs having trouble breathing? Let's learn about this dangerous ARDS (Acute Respiratory Distress Syndrome)!

Have you ever suddenly found it very difficult to breathe, feeling like your chest was constricted? Or do you remember a time when someone you know suddenly became very ill, could not breathe properly and was admitted to the intensive care unit (ICU) of the hospital? Perhaps the cause was a condition called ARDS (Acute Respiratory Distress Syndrome) . This is a bit serious, but if you are properly informed, it is easier to understand many things. Let's talk about this in detail, shall we?

What is ARDS? Let's understand it simply.

Simply put, ARDS is a serious condition that affects our lungs. Think of it this way: Our lungs have tiny air sacs (called alveoli). They're like little grapes on a vine. When we breathe, these air sacs take in oxygen from the air and release it into the blood. But when ARDS occurs, these air sacs fill with fluid. It's like a watery balloon. Then the lungs can't fill with air properly, and the amount of oxygen that goes into the blood drops dramatically. We call this hypoxia. Doctors usually classify ARDS as mild, moderate, or severe . It's determined by comparing the level of oxygen in the blood to the amount of oxygen that needs to be delivered to that level. ARDS can also cause other vital organs like our brain, heart, kidneys, and intestines to not get the oxygen they need. Therefore, ARDS is a dangerous condition that can even be life-threatening. ARDS often develops when someone is being treated in the hospital for another infection, illness, or accident. However, if you develop these symptoms at home, it is important to seek medical attention immediately.

Are there three stages of ARDS?

Doctors sometimes divide ARDS into three stages: Exudative, Proliferative, and Fibrotic. This mainly refers to the degree of swelling and fluid buildup in the lungs, and then the way the lungs begin to heal. Not everyone progresses to Stage 3. This stage involves scarring of the lungs (`(Lung fibrosis)`) and the need for ongoing mechanical ventilation.

How common is ARDS?

This is a serious condition. It affects about 200,000 people a year in the United States alone. Worldwide, it affects about 3 million people a year. ARDS is responsible for about 10% of all admissions to the intensive care unit (ICU). It is also responsible for about 25% of all admissions to the hospital for mechanical ventilation.

What are the symptoms of ARDS? How do you recognize it?

The symptoms of ARDS can vary depending on the cause, the severity of the condition, and any pre-existing lung or heart conditions you have. The main symptoms are:

• Severe difficulty breathing :It feels like you can't breathe, like you're suffocating.
• Rapid and labored breathing : Breathing with great effort, as if gasping for breath.
• Heart rate increases.
• Blue discoloration of nails and lips: This is caused by low oxygen levels in the blood.

Imagine, Mr. Nalin had a high fever and cough for two days. Suddenly, he had difficulty breathing, his chest felt tight. His wife noticed that his nails were turning blue. When they rushed to the hospital, the doctors said it could be ARDS .

ARDS can develop within hours to days of the triggering event, and it can also get worse very quickly.

What are the causes of ARDS?

There are many possible causes of ARDS. Let's look at the main ones:

• Sepsis : The main cause of ARDS is a condition called sepsis. This condition can occur when a severe infection in your lungs (such as pneumonia ) or an infection in another organ spreads throughout your body, causing severe swelling.
• Aspiration pneumonia: If the contents of the stomach (food, liquid) go into the lungs, it can cause severe lung damage and ARDS. This happens when something we eat or drink goes into the airways. This is especially likely to happen to someone who is unconscious or elderly.
• Blood transfusions: There is a risk of ARDS if you are given more than 15 units of blood in a short period of time.
• Covid-19 `( COVID-19 )`: The Covid-19 virus can cause severe ARDS.
• Pancreatitis : A severe inflammation of the pancreas.
• Major accidents or burns: Accidents and falls can directly damage the lungs, or they can damage other organs in the body and cause severe swelling in the lungs.
• Inhalational injury: Inhalation of highly concentrated chemical fumes or smoke.
• Drug overdose : Taking too much of a drug, such as cocaine or opioids.
• Drowning or near drowning: When you drown, water enters your lungs and damages them.

Who is at higher risk of ARDS?

ARDS often develops in people who are already hospitalized due to an accident or illness. However, it does not necessarily mean that you will develop it just because you are in the hospital. There are several factors that increase your risk:

• Being over 65 years of age.
• Tobacco use (cigarette smoking).
• Drug use.
• Having a pre-existing lung disease.

What are the possible complications of ARDS?

ARDS can cause various complications, both while in the hospital and after you go home. Some of them are:

• Blood clots or deep vein thrombosis (DVT).
• Pneumothorax: This can occur due to the pressure exerted by the ventilator on a damaged, hardened lung.
• Delirium: Disturbance of consciousness.
• Multiple organ failure .
• Muscle weakness.
• Lung scarring or fibrosis.
• Post-Traumatic Stress Disorder (PTSD)
• Mental health problems such as anxiety and depression .

How do you diagnose ARDS? (Diagnosis)

Doctors diagnose ARDS based on a physical exam and the results of several tests. Because the symptoms of ARDS are similar to those of chronic lung or heart conditions, the doctor must also rule out other causes. A doctor may order a combination of tests, such as:

• Chest X-ray: To see how much fluid is in the lungs.
• Blood test: Measures the oxygen level in the blood and determines the severity of ARDS.
• Echocardiogram (ultrasound test of the heart): See how the heart is working.
• Electrocardiogram (EKG): Measures the electrical activity of the heart.
• Fingertip sensor `(Pulse oximetry)`: Continuously monitor oxygen levels.
• CT scan (Computed Tomography - CT scan): Get more detailed information about the lungs.
• Taking a sample of secretions from the respiratory tract: Find the cause of the infection.

What are the treatments for ARDS?

The main goal of treating ARDS is to increase the oxygen levels in the blood and prevent organ failure. People with ARDS may need a mechanical ventilator and/or oxygen therapy to increase the oxygen levels in the blood. They may also need help to open airways that have been blocked by damage. Your doctor may take steps to reduce the complications of ARDS, such as:

• Giving sleeping pills (sedation) to help control pain and stay calm.
• Instead of turning you upside down, place yourself in a prone position. This improves oxygen flow.
• Conduct breathing tests and determine the appropriate time to remove the tube and ventilator.
• Giving blood thinners to prevent blood clots.
• Giving diuretics to remove excess fluid from the body.
• Giving medication to reduce fluid buildup in the lungs.
• Antibiotics are given to prevent infections or to treat existing infections.
• Provide active movement and physical therapy to prevent muscle weakness.
• Referral to pulmonary rehabilitation programs to strengthen the lungs and increase lung capacity.

How long does it take to recover from ARDS? What is the recovery rate?

It depends on the severity of the condition and how long it takes for a person's lungs to recover. Most studies suggest that it usually takes six months to a year for normal lung function to return after ARDS. However, some people never fully recover. The survival rate for ARDS is about 55% to 70% , if treated quickly. The survival rate decreases if treatment is delayed or if other organs begin to fail. Your prognosis is determined by factors such as your underlying medical conditions, medical history, and the severity of your respiratory distress. Your doctor will discuss this with you.

Can ARDS be prevented?

There is no specific way to prevent ARDS. However, if you have symptoms of shortness of breath, or if you have lung damage or another condition, seeking medical attention immediately can help prevent the condition from getting worse. Avoiding smoking and limiting alcohol consumption can reduce the risk of developing severe ARDS.

What is life like after ARDS? What should we be aware of?

ARDS can be life-threatening and frightening. But with improved treatments and ventilatory support (especially turning patients on their stomachs to improve oxygen delivery), more people are now surviving, and ARDS complications are decreasing. People under 65 and those who develop ARDS after an accident or blood transfusion generally have a better prognosis. Recovery from ARDS can take a long time. Many people who are taken off the ventilator are able to breathe freely. Some recover completely, but others may develop chronic lung problems. They need the care of a lung specialist (pulmonologist).

"My mother developed ARDS and was in the hospital for months. Even after coming home, she was very tired. She could barely do even the smallest tasks. But after following the doctors' instructions and doing physical therapy, she is slowly getting better. At this time, the support and love of her family are very valuable."

Life after ARDS can be challenging. Be patient and seek support from family and friends as you recover. You may also need help with daily activities until your lungs recover. Talk to your doctor about support groups or other resources that can help you regain your strength.

What is the connection between COVID-19 and ARDS?

These are not the same thing. Someone with COVID-19 can develop ARDS when the virus reaches the lungs. Researchers say that the survival rate for someone with both COVID-19 and ARDS is about 50% to 60%. But this also depends on many factors, such as health history and other medical conditions. Spending time in the intensive care unit (ICU) can be a traumatic and difficult experience. People recovering from ARDS may not be able to return to their normal lives quickly, so you definitely need support. It is important to get professional help and advice during your recovery from ARDS. Ask your medical team about post-intensive care recovery programs and online support groups in your area.

Most Important: Things to Remember (Take-Home Message)

Okay, so here are a few things you need to remember from what we've talked about:

• ARDS is a serious condition that causes damage to the lungs. The air sacs in the lungs fill with fluid, reducing the amount of oxygen that can reach the blood.
• If you experience symptoms such as severe difficulty breathing, rapid breathing, or blue nails/lips, seek medical advice immediately.
• ARDS can have many causes. Sepsis, pneumonia, COVID-19, and severe accidents are just a few.
• Treatment mainly includes oxygen, ventilator support, and management of complications .
• It takes time to recover, and some people may develop long-term lung problems.
• Prompt treatment and good medical care are very important to save lives and reduce complications.
• Support from family and society is essential for someone recovering from ARDS.

Remember, it's important to be aware of this condition. If you or someone you know experiences any of these symptoms, don't panic or panic, but see a doctor right away. That way, you can start the necessary treatment as soon as possible.
