Acute Respiratory Distress Syndrome (ARDS)

What is Acute Respiratory Distress Syndrome (ARDS)?

Acute respiratory distress syndrome (ARDS) is a dangerous lung disease that makes it very hard to breathe. It happens when fluid leaks into the tiny air sacs in the lungs, which stops them from moving enough oxygen into the blood. This means the body’s organs might not get the oxygen they need to work well.

ARDS often appears suddenly, usually within hours or days after a serious illness, infection, injury, or trauma. It can affect anyone, but it is most common in people who are already very sick and need to be in the hospital. Most people with ARDS require intensive care, often including oxygen therapy or mechanical ventilation. 

How Common is ARDS in India?

ARDS or Acute Respiratory Distress Syndrome often happens as a result of serious infections like pneumonia, sepsis, dengue, malaria, and leptospirosis, which are still big health problems in India. 

In a recent study at an Indian hospital with 100 ARDS patients, 66% of cases were caused by infections. Leptospirosis was the most common, making up 41% of cases, followed by malaria at 15% and dengue at 12%. Half of the patients in the study group did not survive, showing how fatal ARDS can be. Also, 47% of patients needed a breathing machine, and among these, the death rate was 93.6%. 

This shows why it is so important to diagnose and treat ARDS as early as possible.

Stages of Acute Respiratory Distress Syndrome (ARDS)

Acute Respiratory Distress Syndrome usually develops in three main phases, each showing how the lungs change as the illness gets worse. These phases of ARDS are:

Symptoms of Acute Respiratory Distress Syndrome (ARDS)

Acute Respiratory Distress Syndrome is a serious, life-threatening lung condition in which fluid builds up in the air sacs (alveoli), preventing enough oxygen from reaching the bloodstream. ARDS usually develops within hours to a few days after a severe illness or injury and requires immediate medical attention. People with ARDS may experience the following symptoms in the early and advanced stages:

Related Diseases Comparison

Acute Respiratory Distress Syndrome is often mistaken for other diseases because they have similar symptoms. Here are the main differences between ARDS and related diseases, such as pneumonia and COPD:

What Causes Acute Respiratory Distress Syndrome (ARDS)?

Acute respiratory distress syndrome occurs when the lungs become severely inflamed and fluid leaks into the air sacs. Some common causes of ARDS are:

• Sepsis: Severe bloodstream infections are the most common cause of ARDS and can trigger widespread inflammation throughout the body and lungs.

• Pneumonia: Serious lung infections can damage lung tissue and cause fluid to accumulate in the air sacs.

• Severe Injuries: Major trauma, particularly chest injuries, can increase the risk of lung damage and the development of ARDS.

• Aspiration: Aspiration happens when food, liquids, vomit, or stomach contents get into the lungs. This can irritate and damage lung tissue, which may lead to ARDS.

• Severe COVID-19: Severe COVID-19 and other viral infections can cause a lot of lung inflammation, which raises the risk of developing ARDS.

• Pancreatitis: Severe inflammation of the pancreas can trigger a systemic inflammatory response that affects the lungs.

• Smoke or Chemical Inhalation: Exposure to toxic smoke, fumes, or harmful chemicals can damage the lungs and lead to acute respiratory distress syndrome.

What are the Complications of Acute Respiratory Distress Syndrome (ARDS)?

If not treated, acute respiratory distress syndrome can cause serious health problems such as the following:

• Respiratory Failure: Severe lung damage can prevent the lungs from delivering enough oxygen to the bloodstream, often requiring ventilator support.

• Lung Scarring: Some ARDS survivors develop permanent scarring of the lung tissue, which may cause long-term breathing difficulties.

• Blood Clots: Extended periods of immobility and critical illness can increase the risk of blood clots in the legs or lungs.

• Infections: Prolonged ICU stays and the use of mechanical ventilation can raise the likelihood of hospital-acquired infections.

• Organ Failure: Low oxygen levels in the blood can impair the function of vital organs, including the kidneys, liver, and heart.

• Depression and Anxiety: The physical and emotional stress of ARDS and intensive care treatment can contribute to mental health challenges during recovery.

• Memory and Cognitive Problems: Some patients experience long-term issues with memory, concentration, decision-making, and overall cognitive function after recovery.

When Should I See My Healthcare Provider?

Seek immediate medical attention if you experience any symptoms of ARDS, such as the following:

• Severe or worsening shortness of breath.

• Rapid breathing or difficulty breathing.

• Bluish lips, skin, or fingernails.

• Significant breathing problems after an injury or illness.

• Chest pain or chest tightness.

• Sudden confusion or altered mental status.

• Symptoms of severe infection, such as high fever and breathing difficulty.

How is Acute Respiratory Distress Syndrome (ARDS) Diagnosed?

Doctors use several tests to diagnose ARDS and identify its underlying cause. These may include:

How is Acute Respiratory Distress Syndrome (ARDS) Managed?

Treatment aims to raise oxygen levels, support the lungs, and treat the underlying cause of ARDS. Here are some common ways to manage ARDS:

• Oxygen Therapy: Taking extra oxygen helps increase the amount of oxygen in the blood and keeps organs working properly.

• Mechanical Ventilation: In severe cases, a machine called a ventilator may be used to help the patient breathe.

• Treating the Underlying Cause: It is important to find and treat whatever is causing ARDS to help the patient recover.

• Medications: Doctors may prescribe medicines to treat infections and manage complications.

• Fluid Management: Doctors carefully control how much fluid the patient gets to avoid too much fluid in the lungs.

• Rehabilitation: Physical and pulmonary rehabilitation can help restore strength and lung function after recovery.

Medicines Used to Treat Acute Respiratory Distress Syndrome (ARDS)

Some crucial medicines used to treat Acute Respiratory Distress Syndrome include:

• Bronchodilator medicines are used when indicated.

• Diuretics are used to remove extra fluid from your body.

• Intravenous fluids (carefully managed).

• Vasopressor medicines for patients with shock.

• Corticosteroids in selected patients.

• Blood thinners to reduce the risk of blood clots.

• Pain relievers and sedatives for patients on ventilators.

Disclaimer: Please do not use the medicines listed above on your own. Always talk to a doctor before starting, stopping, or changing any prescribed medication.

Living with Acute Respiratory Distress Syndrome (ARDS) in India: Daily Challenges & Recovery

Recovering from ARDS can take several months, especially for those who need intensive care. Here are some practical tips and daily care strategies for people living with ARDS:

Acute Respiratory Distress Syndrome (ARDS) During Pregnancy

Although ARDS during pregnancy does not happen often, it can be very serious for both the mother and the baby. It can be caused by severe infections, pneumonia, sepsis, trauma, or pregnancy complications like preeclampsia. Getting diagnosed and treated early in a specialised hospital is important for the best possible outcome.

Pregnant women with ARDS usually need close monitoring in intensive care to make sure they get enough oxygen. When obstetricians, intensive care doctors, and lung specialists work together, it can greatly improve the health of both mother and baby.

Here is how you can manage ARDS during pregnancy:

• If you have severe shortness of breath or trouble breathing, get medical help right away.

• Go to all your prenatal check-ups so any pregnancy complications can be found and treated early.

• Carefully follow your doctor’s treatment plan and instructions for any medicines.

• Keep up with recommended vaccines to lower your risk of serious lung infections.

• Eat a healthy diet and drink enough water to help keep you and your baby well.

What is the Prognosis for Acute Respiratory Distress Syndrome (ARDS)?

The prognosis for ARDS varies based on how serious the lung injury is, what caused it, the patient’s age, and their overall health. Some people recover fully, but others may have lasting breathing problems, lower lung function, or emotional struggles. Getting treatment early and taking part in rehabilitation can help people recover better. Those who survive severe ARDS might need several months to recover and may need ongoing medical care. Regular check-ups can help manage any remaining symptoms and improve quality of life.

Can Acute Respiratory Distress Syndrome (ARDS) Be Reversed?

There is no exact cure for ARDS, but it can get better with quick treatment and supportive care. Many people recover as their lungs heal, though it can take weeks or even months.

How quickly someone recovers depends on how soon they get treatment and how serious their illness is. Rehabilitation and healthy lifestyle changes can also help the lungs heal and support long-term recovery.

How Can I Prevent Acute Respiratory Distress Syndrome (ARDS)?

While ARDS is not always preventable, there are steps you can take to lower the risk. These may include:

• Get medical help quickly if you have a serious infection.

• Stay up to date with recommended vaccines.

• Take care of any long-term health conditions you have.

• Use safety precautions to help prevent serious injuries.

• Try to limit your contact with harmful chemicals and toxic fumes.

• Practice good hygiene to help lower your risk of infection.

Acute Respiratory Distress Syndrome (ARDS) Treatment Cost in India

The cost of ARDS treatment depends on its cause, the duration of ICU stay, whether a ventilator is needed, and the need for tests and rehab. The cost breakdown of ARDS treatment in India is as follows:

Disclaimer: The above-mentioned expenses are approximate and may differ for every patient. The severity of ARDS, the length of ICU stay, the kind of respiratory assistance required, the hospital's facilities, any expert consultations, testing, and other therapies together affect costs.

Does Health Insurance Cover ARDS?

Yes. Health insurance usually covers Acute Respiratory Distress Syndrome (ARDS) when hospitalisation is needed. This often includes costs for ICU care, ventilator support, oxygen therapy, doctor fees, diagnostic tests, medicines, and other hospital expenses. Ambulance charges are also covered by most mediclaim policies.

Coverage may depend on the policy terms, inclusions, sub-limits, exclusions, and your sum insured.

How Much Health Insurance Coverage is Needed for ARDS Treatment?

Treating ARDS often means staying in the ICU, using a ventilator, having special tests, and spending more time in the hospital. These can be extremely expensive. For people with no pre-existing condition, a health insurance cover of ₹10 lakh is usually enough. Adults, senior citizens, or those with existing health issues are advised to opt for a cover of ₹15 lakh or more for better financial protection.
