 What causes Respiratory Failure ? 
 Diseases and conditions that impair breathing can cause respiratory failure. These disorders may affect the muscles, nerves, bones, or tissues that support breathing, or they may affect the lungs directly.
                
When breathing is impaired, your lungs can't easily move oxygen into your blood and remove carbon dioxide from your blood (gas exchange). This can cause a low oxygen level or high carbon dioxide level, or both, in your blood.
                
Respiratory failure can occur as a result of:
                
Conditions that affect the nerves and muscles that control breathing. Examples include muscular dystrophy, amyotrophic lateral sclerosis (ALS), spinal cord injuries, and stroke.
                
Damage to the tissues and ribs around the lungs. An injury to the chest can cause this damage.
                
Problems with the spine, such as scoliosis (a curve in the spine). This condition can affect the bones and muscles used for breathing.
                
Drug or alcohol overdose. An overdose affects the area of the brain that controls breathing. During an overdose, breathing becomes slow and shallow.
                
Lung diseases and conditions, such as COPD (chronic obstructive pulmonary disease), pneumonia, ARDS (acute respiratory distress syndrome), pulmonary embolism, and cystic fibrosis. These diseases and conditions can affect the flow of air and blood into and out of your lungs. ARDS and pneumonia affect gas exchange in the air sacs.
                
Acute lung injuries. For example, inhaling harmful fumes or smoke can injure your lungs.
                
Normal Lungs and Conditions Causing Respiratory Failure
This is a medical question of type : susceptibility 
 Who is at risk for Respiratory Failure? ? 
 People who have diseases or conditions that affect the muscles, nerves, bones, or tissues that support breathing are at risk for respiratory failure. People who have lung diseases or conditions also are at risk for respiratory failure. For more information, go to "What Causes Respiratory Failure?"
This is a medical question of type : symptoms 
 What are the symptoms of Respiratory Failure ? 
 The signs and symptoms of respiratory failure depend on its underlying cause and the levels of oxygen and carbon dioxide in the blood.
                
A low oxygen level in the blood can cause shortness of breath and air hunger (feeling like you can't breathe in enough air). If the level of oxygen is very low, it also can cause a bluish color on the skin, lips, and fingernails. A high carbon dioxide level can cause rapid breathing and confusion.
                
Some people who have respiratory failure may become very sleepy or lose consciousness. They also may develop arrhythmias (ah-RITH-me-ahs), or irregular heartbeats. These symptoms can occur if the brain and heart are not getting enough oxygen.
This is a medical question of type : exams and tests 
 How to diagnose Respiratory Failure ? 
 Your doctor will diagnose respiratory failure based on your medical history, a physical exam, and test results. Once respiratory failure is diagnosed, your doctor will look for its underlying cause.
                
Medical History
                
Your doctor will ask whether you might have or have recently had diseases or conditions that could lead to respiratory failure.
                
Examples include disorders that affect the muscles, nerves, bones, or tissues that support breathing. Lung diseases and conditions also can cause respiratory failure.
                
For more information, go to "What Causes Respiratory Failure?"
                
Physical Exam
                
During the physical exam, your doctor will look for signs of respiratory failure and its underlying cause.
                
Respiratory failure can cause shortness of breath, rapid breathing, and air hunger (feeling like you can't breathe in enough air). Using a stethoscope, your doctor can listen to your lungs for abnormal sounds, such as crackling.
                
Your doctor also may listen to your heart for signs of an arrhythmia (irregular heartbeat). An arrhythmia can occur if your heart doesn't get enough oxygen.
                
Your doctor might look for a bluish color on your skin, lips, and fingernails. A bluish color means your blood has a low oxygen level.
                
Respiratory failure also can cause extreme sleepiness and confusion, so your doctor might check how alert you are.
                
Diagnostic Tests
                
To check the oxygen and carbon dioxide levels in your blood, you may have: 
                
Pulse oximetry. For this test, a small sensor is attached to your finger or ear. The sensor uses light to estimate how much oxygen is in your blood.
                
Arterial blood gas test. This test measures the oxygen and carbon dioxide levels in your blood. A blood sample is taken from an artery, usually in your wrist. The sample is then sent to a laboratory, where its oxygen and carbon dioxide levels are measured.
                
A low level of oxygen or a high level of carbon dioxide in the blood (or both) is a possible sign of respiratory failure.
                
Your doctor may recommend other tests, such as a chest x ray, to help find the underlying cause of respiratory failure. A chest x ray is a painless test that takes pictures of the structures inside your chest, such as your heart, lungs, and blood vessels.
                
If your doctor thinks that you have an arrhythmia as a result of respiratory failure, he or she may recommend an EKG (electrocardiogram). An EKG is a simple, painless test that detects and records the heart's electrical activity.

 What is (are) Idiopathic Pulmonary Fibrosis ? 
 Pulmonary fibrosis (PULL-mun-ary fi-BRO-sis) is a disease in which tissue deep in your lungs becomes thick and stiff, or scarred, over time. The formation of scar tissue is called fibrosis.
                
As the lung tissue thickens, your lungs can't properly move oxygen into your bloodstream. As a result, your brain and other organs don't get the oxygen they need. (For more information, go to the "How the Lungs Work" section of this article.)
                
Sometimes doctors can find out what's causing fibrosis. But in most cases, they can't find a cause. They call these cases idiopathic (id-ee-o-PATH-ick) pulmonary fibrosis (IPF).
                
IPF is a serious disease that usually affects middle-aged and older adults. IPF varies from person to person. In some people, fibrosis happens quickly. In others, the process is much slower. In some people, the disease stays the same for years.
                
IPF has no cure yet. Many people live only about 3 to 5 years after diagnosis. The most common cause of death related to IPF is respiratory failure. Other causes of death include pulmonary hypertension (HI-per-TEN-shun), heart failure, pulmonary embolism (EM-bo-lizm), pneumonia (nu-MO-ne-ah), and lung cancer.
                
Genetics may play a role in causing IPF. If more than one member of your family has IPF, the disease is called familial IPF.
                
Research has helped doctors learn more about IPF. As a result, they can more quickly diagnose the disease now than in the past. Also, researchers are studying several medicines that may slow the progress of IPF. These efforts may improve the lifespan and quality of life for people who have the disease.
This is a medical question of type : causes 
 What causes Idiopathic Pulmonary Fibrosis ? 
 Sometimes doctors can find out what is causing pulmonary fibrosis (lung scarring). For example, exposure to environmental pollutants and certain medicines can cause the disease.
                
Environmental pollutants include inorganic dust (silica and hard metal dusts) and organic dust (bacteria and animal proteins).
                
Medicines that are known to cause pulmonary fibrosis in some people include nitrofurantoin (an antibiotic), amiodarone (a heart medicine), methotrexate and bleomycin (both chemotherapy medicines), and many other medicines.
                
In most cases, however, the cause of lung scarring isnt known. These cases are called idiopathic pulmonary fibrosis (IPF). With IPF, doctors think that something inside or outside of the lungs attacks them again and again over time.
                
These attacks injure the lungs and scar the tissue inside and between the air sacs. This makes it harder for oxygen to pass through the air sac walls into the bloodstream.
                
The following factors may increase your risk of IPF:
                
Cigarette smoking
                
Viral infections, including Epstein-Barr virus (which causes mononucleosis), influenza A virus, hepatitis C virus, HIV, and herpes virus 6
                
Genetics also may play a role in causing IPF. Some families have at least two members who have IPF.
                
Researchers have found that 9 out of 10 people who have IPF also have gastroesophageal reflux disease (GERD). GERD is a condition in which acid from your stomach backs up into your throat.
                
Some people who have GERD may regularly breathe in tiny drops of acid from their stomachs. The acid can injure their lungs and lead to IPF. More research is needed to confirm this theory.
This is a medical question of type : symptoms 
 What are the symptoms of Idiopathic Pulmonary Fibrosis ? 
 The signs and symptoms of idiopathic pulmonary fibrosis (IPF) develop over time. They may not even begin to appear until the disease has done serious damage to your lungs. Once they occur, they're likely to get worse over time.
                
The most common signs and symptoms are:
                
Shortness of breath. This usually is the main symptom of IPF. At first, you may be short of breath only during exercise. Over time, you'll likely feel breathless even at rest.
                
A dry, hacking cough that doesn't get better. Over time, you may have repeated bouts of coughing that you can't control.
                
Other signs and symptoms that you may develop over time include:
                
Rapid, shallow breathing
                
Gradual, unintended weight loss
                
Fatigue (tiredness) or malaise (a general feeling of being unwell)
                
Aching muscles and joints
                
Clubbing, which is the widening and rounding of the tips of the fingers or toes
                
Clubbing
                

                
IPF may lead to other medical problems, including a collapsed lung, lung infections, blood clots in the lungs, and lung cancer.
                
As the disease worsens, you may develop other potentially life-threatening conditions, including respiratory failure, pulmonary hypertension, and heart failure.

 What is (are) Stroke ? 
 A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells.
                
If brain cells die or are damaged because of a stroke, symptoms occur in the parts of the body that these brain cells control. Examples of stroke symptoms include sudden weakness; paralysis or numbness of the face, arms, or legs (paralysis is an inability to move); trouble speaking or understanding speech; and trouble seeing.
                
A stroke is a serious medical condition that requires emergency care. A stroke can cause lasting brain damage, long-term disability, or even death.
                
If you think you or someone else is having a stroke, call 911 right away. Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. During a stroke, every minute counts.
                
Overview
                
The two main types of stroke are ischemic (is-KE-mik) and hemorrhagic (hem-ah-RAJ-ik). Ischemic is the more common type of stroke.
                
An ischemic stroke occurs if an artery that supplies oxygen-rich blood to the brain becomes blocked. Blood clots often cause the blockages that lead to ischemic strokes.
                
A hemorrhagic stroke occurs if an artery in the brain leaks blood or ruptures (breaks open). The pressure from the leaked blood damages brain cells. High blood pressure and aneurysms (AN-u-risms) are examples of conditions that can cause hemorrhagic strokes. (Aneurysms are balloon-like bulges in an artery that can stretch and burst.)
                
Another condition thats similar to a stroke is a transient ischemic attack, also called a TIA or mini-stroke. A TIA occurs if blood flow to a portion of the brain is blocked only for a short time. Thus, damage to the brain cells isnt permanent (lasting).
                
Like ischemic strokes, TIAs often are caused by blood clots. Although TIAs are not full-blown strokes, they greatly increase the risk of having a stroke. If you have a TIA, its important for your doctor to find the cause so you can take steps to prevent a stroke.
                
Both strokes and TIAs require emergency care.
                
Outlook
                
Stroke is a leading cause of death in the United States. Many factors can raise your risk of having a stroke. Talk with your doctor about how you can control these risk factors and help prevent a stroke.
                
If you have a stroke, prompt treatment can reduce damage to your brain and help you avoid lasting disabilities. Prompt treatment also may help prevent another stroke.
                
Researchers continue to study the causes and risk factors for stroke. Theyre also finding new and better treatments and new ways to help the brain repair itself after a stroke.
This is a medical question of type : symptoms 
 What are the symptoms of Stroke ? 
 The signs and symptoms of a stroke often develop quickly. However, they can develop over hours or even days.
                
The type of symptoms depends on the type of stroke and the area of the brain thats affected. How long symptoms last and how severe they are vary among different people.
                
Signs and symptoms of a stroke may include:
                
Sudden weakness
                
Paralysis (an inability to move) or numbness of the face, arms, or legs, especially on one side of the body
                
Confusion
                
Trouble speaking or understanding speech
                
Trouble seeing in one or both eyes
                
Problems breathing
                
Dizziness, trouble walking, loss of balance or coordination, and unexplained falls
                
Loss of consciousness
                
Sudden and severe headache
                
A transient ischemic attack (TIA) has the same signs and symptoms as a stroke. However, TIA symptoms usually last less than 12 hours (although they may last up to 24 hours). A TIA may occur only once in a persons lifetime or more often.
                
At first, it may not be possible to tell whether someone is having a TIA or stroke. All stroke-like symptoms require medical care.
                
If you think you or someone else is having a TIA or stroke, call 911 right away. Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. During a stroke, every minute counts.
                
Stroke Complications
                
After youve had a stroke, you may develop other complications, such as:
                
Blood clots and muscle weakness. Being immobile (unable to move around) for a long time can raise your risk of developing blood clots in the deep veins of the legs. Being immobile also can lead to muscle weakness and decreased muscle flexibility.
                
Problems swallowing and pneumonia. If a stroke affects the muscles used for swallowing, you may have a hard time eating or drinking. You also may be at risk of inhaling food or drink into your lungs. If this happens, you may develop pneumonia.
                
Loss of bladder control. Some strokes affect the muscles used to urinate. You may need a urinary catheter (a tube placed into the bladder) until you can urinate on your own. Use of these catheters can lead to urinary tract infections. Loss of bowel control or constipation also may occur after a stroke.
This is a medical question of type : prevention 
 How to prevent Stroke ? 
 Taking action to control your risk factors can help prevent or delay a stroke. If youve already had a stroke, these actions can help prevent another one.
                
Be physically active. Physical activity can improve your fitness level and health. Talk with your doctor about what types and amounts of activity are safe for you.
                
Dont smoke, or if you smoke or use tobacco, quit. Smoking can damage and tighten blood vessels and raise your risk of stroke. Talk with your doctor about programs and products that can help you quit. Also, secondhand smoke can damage the bloodvessels.
                
Maintain a healthy weight. If youre overweight or obese, work with your doctor to create a reasonable weight loss plan. Controlling your weight helps you control risk factors for stroke.
                
Make heart-healthy eating choices. Heart-healthy eating can help lower your risk or prevent a stroke.
                
Manage stress. Use techniques to lower your stress levels.
                
If you or someone in your family has had a stroke, be sure to tell your doctor. By knowing your family history of stroke, you may be able to lower your risk factors and prevent or delay a stroke. If youve had a transient ischemic attack (TIA), dont ignore it. TIAs are warnings, and its important for your doctor to find the cause of the TIA so you can take steps to prevent a stroke.
This is a medical question of type : information 
 What is (are) ARDS ? 
 ARDS, or acute respiratory distress syndrome, is a lung condition that leads to low oxygen levels in the blood. ARDS can be life threatening because your body's organs need oxygen-rich blood to work well.
                
People who develop ARDS often are very ill with another disease or have major injuries. They might already be in the hospital when they develop ARDS.
                
Overview
                
To understand ARDS, it helps to understand how the lungs work. When you breathe, air passes through your nose and mouth into your windpipe. The air then travels to your lungs' air sacs. These sacs are called alveoli (al-VEE-uhl-eye).
                
Small blood vessels called capillaries (KAP-ih-lare-ees) run through the walls of the air sacs. Oxygen passes from the air sacs into the capillaries and then into the bloodstream. Blood carries the oxygen to all parts of the body, including the body's organs.
                
In ARDS, infections, injuries, or other conditions cause fluid to build up in the air sacs. This prevents the lungs from filling with air and moving enough oxygen into the bloodstream.
                
As a result, the body's organs (such as the kidneys and brain) don't get the oxygen they need. Without oxygen, the organs may not work well or at all.
                
People who develop ARDS often are in the hospital for other serious health problems. Rarely, people who aren't hospitalized have health problems that lead to ARDS, such as severe pneumonia.
                
If you have trouble breathing, call your doctor right away. If you have severe shortness of breath, call 911.
                
Outlook
                
More people are surviving ARDS now than in the past. One likely reason for this is that treatment and care for the condition have improved. Survival rates for ARDS vary depending on age, the underlying cause of ARDS, associated illnesses, and other factors.
                
Some people who survive recover completely. Others may have lasting damage to their lungs and other health problems.
                
Researchers continue to look for new and better ways to treat ARDS.
This is a medical question of type : causes 
 What causes ARDS ? 
 Many conditions or factors can directly or indirectly injure the lungs and lead to ARDS. Some common ones are:
                
Sepsis. This is a condition in which bacteria infect the bloodstream.
                
Pneumonia. This is an infection in the lungs.
                
Severe bleeding caused by an injury to the body.
                
An injury to the chest or head, like a severe blow.
                
Breathing in harmful fumes or smoke.
                
Inhaling vomited stomach contents from the mouth.
                
It's not clear why some very sick or seriously injured people develop ARDS and others don't. Researchers are trying to find out why ARDS develops and how to prevent it.
This is a medical question of type : susceptibility 
 Who is at risk for ARDS? ? 
 People at risk for ARDS have a condition or illness that can directly or indirectly injure their lungs.
                
Direct Lung Injury
                
Conditions that can directly injure the lungs include:
                
Pneumonia. This is an infection in the lungs.
                
Breathing in harmful fumes or smoke.
                
Inhaling vomited stomach contents from the mouth.
                
Using a ventilator. This is a machine that helps people breathe; rarely, it can injure the lungs.
                
Nearly drowning.
                
Indirect Lung Injury
                
Conditions that can indirectly injure the lungs include:
                
Sepsis. This is a condition in which bacteria infect the bloodstream.
                
Severe bleeding caused by an injury to the body or having many blood transfusions.
                
An injury to the chest or head, such as a severe blow.
                
Pancreatitis (PAN-kre-a-TI-tis). This is a condition in which the pancreas becomes irritated or infected. The pancreas is a gland that releases enzymes and hormones.
                
Fat embolism (EM-bo-lizm). This is a condition in which fat blocks an artery. A physical injury, like a broken bone, can lead to a fat embolism.
                
Drug reaction.
