15283 Acute Respiratory Distress Syndrome Ards

Overview

Acute Respiratory Distress Syndrome (ARDS) is a serious, life-threatening lung condition that happens when fluid leaks into the tiny air sacs in your lungs. This makes it very hard to breathe and lowers the amount of oxygen that reaches your blood and vital organs. ARDS usually develops quickly in people who are already very ill, for example from sepsis, pneumonia, or a severe injury. It is a medical emergency that requires hospital care, often in an intensive care unit (ICU).

ARDS is not common. It affects only a small number of people who are already seriously ill in hospital. However, when it does happen, it is a very serious condition.

ARDS can affect anyone, but it is more likely in adults over 65, people who smoke, and people with chronic lung disease. It is also more common in people with severe infections, sepsis, pancreatitis, or major trauma. Both men and women can develop ARDS.

Symptoms

Common symptoms

• Severe shortness of breath
• Breathing very fast (rapid breathing)
• Feeling like you cannot get enough air
• Low oxygen levels, which can cause bluish lips or skin
• Confusion or extreme tiredness
• Cough (sometimes with frothy or pink sputum)

Symptoms in children

• Rapid or labored breathing
• Flaring of the nostrils
• Grunting sounds while breathing
• Blue or pale lips, tongue, or skin
• Unusual drowsiness or poor feeding

Symptoms in older adults

• Severe breathlessness
• Confusion or sudden changes in behavior
• Low blood pressure
• Very fast breathing or heart rate
• Extreme weakness or difficulty staying awake

Causes

Main causes

• Sepsis (a serious infection that spreads through the body)
• Pneumonia, including viral pneumonia (such as from COVID-19 or the flu)
• Severe trauma to the chest or other major injuries
• Inhaling harmful substances (like smoke, chemical fumes, or vomit)
• Pancreatitis (inflammation of the pancreas)
• Severe burns or blood transfusions that cause lung injury

Risk factors

• Being in the hospital for a severe illness or injury
• Age over 65
• Smoking or chronic lung disease
• Weakened immune system
• Heavy alcohol use
• Having had a lung injury or major surgery

When to see a doctor

See a doctor urgently if:

• If you or someone else has sudden or worsening trouble breathing, seek emergency care immediately.
• If you are already in hospital and notice breathing difficulty, tell a nurse or doctor right away.

Book a routine appointment if:

• If you have an ongoing health condition that could increase your risk (like chronic lung disease or heart problems), talk to your doctor about managing your health.
• If you are recovering from a severe illness and have new concerns about your breathing, book an appointment.

Diagnosis

Doctors usually diagnose ARDS based on your medical history, symptoms, a physical exam, and test results. There is no single test for ARDS. Your doctor will rule out other conditions that can cause similar symptoms, such as heart failure.

Tests that may be done

• Blood tests to check oxygen levels and look for signs of infection
• Chest X-ray to look for fluid in the lungs
• CT scan for a more detailed image of the lungs
• Echocardiogram to rule out heart problems
• A test called arterial blood gas to measure oxygen and carbon dioxide in your blood

What to expect at your appointment

If a doctor suspects ARDS, you will be admitted to an intensive care unit (ICU). You will be closely monitored with machines that check your heart, breathing, and oxygen levels. You may need oxygen or a breathing machine (ventilator) to help your lungs work.

Treatment

ARDS is treated in an intensive care unit (ICU). The main goals are to get enough oxygen into your blood and to treat the underlying cause. Treatment includes breathing support, careful management of fluids, and treatment of infections or injuries. The healthcare team will watch you closely and adjust your treatment as needed.

Self-care at home

• Follow all instructions from your ICU team.
• If you are awake, let them know if you feel more breathless or in pain.
• During recovery, take part in rehabilitation as recommended to regain strength.

Medical treatments

Oxygen therapy is often given first, either through a mask or small tubes in your nose. In more severe cases, a breathing tube and ventilator (mechanical ventilation) help move air into and out of your lungs. Doctors may also use medicines to reduce inflammation, treat infection, or prevent blood clots, but the exact medicines depend on your situation. You may receive fluids or nutrition through a vein if you are not able to eat normally.

When is surgery considered?

Surgery is not a usual treatment for ARDS itself. However, you may need a small tube inserted through your chest to drain fluid or air around the lungs, or a procedure to place a tracheostomy (a breathing tube in your neck) if you need a ventilator for a long time.

Living with this condition

Recovery from ARDS can take weeks or months. Many people feel weak, tired, and short of breath even after leaving the hospital. You may need pulmonary rehabilitation (a program of exercise and education) to help your lungs and muscles get stronger. Give yourself time and be patient with your recovery.

Lifestyle tips

• Quit smoking and avoid secondhand smoke to protect your lungs.
• Avoid lung irritants like air pollution, chemical fumes, and respiratory infections.
• Get enough rest and slowly increase your activity as your energy improves.
• Take all medications and follow up with your healthcare provider as advised.

Diet and exercise

Eating a balanced diet with plenty of fruits, vegetables, proteins, and whole grains supports healing. Start with gentle exercises such as walking or light stretching, and gradually increase activity according to your doctor's advice. You may also work with a physiotherapist to rebuild strength safely.

Mental health and emotional wellbeing

It is very normal to feel anxious, depressed, or overwhelmed after a serious illness like ARDS. You may have memories of the hospital or worry about your recovery. Talk to your healthcare team about your feelings. They can connect you with counseling or support groups.

Prevention

There is no sure way to prevent ARDS, but you can reduce your chances of getting the serious infections and injuries that often cause it. This includes getting recommended vaccines, quitting smoking, managing health conditions, and seeking early treatment for infections.

Vaccines

Vaccines for flu, COVID-19, and pneumonia can help prevent some infections that can lead to ARDS. Talk to your healthcare provider about which vaccines are recommended for you.

Screening programmes

There is no routine screening test for ARDS for healthy people. If you are in the hospital for a serious illness or injury, your care team will monitor your breathing and oxygen levels closely to catch any problems early.

Complications

If left untreated

• Organ failure, especially kidneys and liver
• Blood clots in the lungs or legs
• Lung damage and scarring (pulmonary fibrosis)
• Muscle weakness and loss of muscle mass
• Memory problems or difficulty thinking clearly (cognitive impairment)

Long-term outlook

ARDS is very serious, and some people do not survive. However, many people do recover, especially with prompt treatment in an intensive care unit. Recovery can take time, and you may need ongoing support, but there is hope. Your healthcare team will work with you to improve your strength and quality of life after ARDS.
