Question: what is respiratory failure?

Signs of acute respiratory failure include dizziness, shortness of breath, and a bluish discoloration of your extremities. It can be life threatening and requires immediate medical care.

Question: What are the usual symptoms of respiratory failure?

The symptoms of acute respiratory failure depend on its underlying cause. Symptoms can also differ by the amount of oxygen and carbon dioxide in your blood.
People with low oxygen may experience
:
shortness of breath
a bluish coloration on lips, fingertips, or toes
drowsiness
difficulty performing routine activities, such as dressing or climbing stairs, due to extreme tiredness
People with high carbon dioxide levels may experience:
rapid breathing
confusion
blurred vision
headaches

Question: causes of respiratory failure?

Acute respiratory failure has several causes:
Obstruction
When something lodges in your throat, you may have trouble getting enough oxygen into your lungs. Obstruction can also occur in people with COPD or asthma when an exacerbation causes the airways to narrow.
Injury
An injury that impairs or compromises your respiratory system can negatively affect the amount of oxygen or carbon dioxide in your blood.
For instance, a spinal cord or brain injury can immediately affect your breathing. If the brain cannot relay messages to the lungs, the lungs may not function properly.
Rib or chest injuries can also affect your breathing.
Acute respiratory distress syndrome
Acute respiratory distress syndrome (ARDS) is a serious condition that causes fluid to build up in your lungs. It results in low oxygen in the blood. People who develop ARDS typically have an underlying health condition, such as:
pneumonia
pancreatitis
sepsis
trauma to the head or chest
blood transfusions
near drowning
lung injuries related to inhaling smoke or chemical products
Drug or alcohol use
Experiencing a drug overdose or drinking too much alcohol can also impair brain function and hinder breathing.
Chemical inhalation
Inhaling toxic chemicals, smoke, or fumes can cause acute respiratory failure. These chemicals may injure or damage lung tissue, including the air sacs and capillaries.
Stroke
A stroke happens when something disrupts blood flow to the brain. Strokes often affect only one side of the brain.
Although strokes present with some warning signs, such as slurred speech or confusion, they typically occur suddenly. If you have a stroke, you can lose the ability to breathe.
Infection
Infections can cause respiratory distress. Pneumonia, in particular, may cause respiratory failure, even without ARDS.

Question: What are the potential risk factors associated with respiratory failure?

You may be at risk for acute respiratory failure if you:
smoke tobacco products
drink alcohol excessively
have a family history of respiratory disease or conditions
have an injury to the spine, brain, or chest
have a compromised immune system
have chronic respiratory conditions, such as lung cancer, COPD, or asthma

Question: How do doctors usually figure out if someone has respiratory failure, diagnosis?

Acute respiratory failure requires immediate medical attention. You may require supplemental oxygen to help you breathe and prevent organ damage.
When you're in stable condition, a doctor may diagnose you by:
performing a physical exam
asking questions about your personal or family health history
checking your body's oxygen and carbon dioxide levels with a pulse oximetry device and an arterial blood gas test
ordering a chest X-ray of your lungs

Question: What are the possible complications that could arise from respiratory failure?

Because acute respiratory failure means your organs are not receiving the oxygen-rich blood they need to function, complications can involve multiple organ systems. Acute respiratory failure can often
be fatal.
Pulmonary complications, or those affecting the lungs, can include:
pulmonary embolism
pulmonary fibrosis
pneumonia
pneumothorax (collapsed lung)
Other complications can include:
gastrointestinal hemorrhage
renal (kidney) failure
hepatic (liver) failure
