Acute Respiratory Failure

AMBULATORY CARE:

Acute respiratory failure (ARF)

is a condition that happens when your lungs cannot get enough oxygen into your blood. ARF can also happen when your lungs cannot get the carbon dioxide out of your blood. A buildup of carbon dioxide in your blood can cause damage to your organs. The decrease in oxygen and the buildup of carbon dioxide can happen at the same time. Acute respiratory failure may develop in minutes, hours, or days.

The Lungs

Call your local emergency number (911 in the US) or have someone call if:

  • You have more trouble catching your breath.
  • You have stopped breathing.

Call your doctor if:

  • You have new symptoms.
  • Your symptoms get worse.
  • You have questions or concerns about your condition or care.

Treatment

depends on the cause and how severe your symptoms are. You may need any of the following:

  • Medicines may be given to open your airways or relieve fluid buildup in your arms or legs. You may also need medicines to treat the cause of your ARF.
  • Extra oxygen may be given if your blood oxygen levels are low.
  • Ventilation helps get oxygen into your lungs and carbon dioxide out. Ventilation also makes the work of breathing easier. Some systems, such as a CPAP or BiPAP, may only be needed while you sleep. A mechanical ventilator may be needed some or all of the time. It is attached to a mask or breathing tube.
    CPAP
  • A procedure may be used to drain fluid if you have a pleural effusion (fluid between the lining of the lungs and the chest). Air may be drained from around your lung if you have a collapsed lung.

Manage or prevent shortness of breath:

  • Use your oxygen as directed. You may need extra oxygen if your blood oxygen level is lower than it should be.
  • Use pursed-lip breathing any time you feel short of breath. Take a deep breath in through your nose. Slowly breathe out through your mouth with your lips pursed for twice as long as you inhaled. You can also practice this breathing pattern while you bend, lift, climb stairs, or exercise. It slows down your breathing and helps move more air in and out of your lungs.
    Breathe in Breathe out

Manage ARF:

  • Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung damage and make your symptoms worse. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products. Secondhand smoke can also make your symptoms worse. Avoid others who are smoking.
  • Prevent the spread of germs. Wash your hands often with soap and water. Use gel hand cleanser when soap and water are not available. Do not touch your eyes, nose, or mouth unless you have washed your hands first. Cover your mouth when you cough. Cough into a tissue or your shirtsleeve so you do not spread germs from your hands. If you are sick, stay away from others as much as possible.

  • Limit alcohol. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
  • Ask about vaccines you may need. Vaccines can help prevent some lung infections. Examples include pneumonia, COVID-19, pertussis (whooping cough), tuberculosis (TB), and diphtheria. Get a flu vaccine every year as soon as it is recommended, usually in September or October.
  • Prepare for emergencies. Keep phone numbers for your healthcare provider, hospital, and someone close to you with you at all times.

Follow up with your doctor as directed:

You may need more tests or treatments. Write down your questions so you remember to ask them during your visits.
