The mediastinum is the cartilage that forms the lower portion of the breast bone.
What occurs when the body Cannot get the air it needs to function?
Doctors call this hypoxemic respiratory failure. It means that a person is not exchanging oxygen properly in their lungs. This may be due to swelling or damage to the lungs. A person with type 1 acute respiratory failure has very low oxygen levels.
Which term describes the loss of consciousness that occurs when the body Cannot?
Fainting, or syncope, is a sudden and temporary loss of consciousness. This usually occurs due to a lack of oxygen reaching the brain. Many things can cause oxygen deprivation to the brain, including low blood pressure.
What is the loss of consciousness that occurs when the body Cannot get the oxygen it needs to function?
Anoxia happens when your body or brain completely loses its oxygen supply. Anoxia is usually a result of hypoxia. This means that a part of your body doesn’t have enough oxygen.
Which term describes the loss of consciousness?
Which term describes the loss of consciousness that occurs when the body cannot get the air it needs to function? asphyxia. walking pneumonia is also known as mycoplasma pneumonia. true. The thick mucus secreted by the tissues lining the respiratory passages is known as.

Which term describes the condition of having below normal oxygen levels in the body tissues and cells?
Hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).
What causes decreased level of consciousness?
An altered level of consciousness can result from a variety of factors, including alterations in the chemical environment of the brain (e.g. exposure to poisons or intoxicants), insufficient oxygen or blood flow in the brain, and excessive pressure within the skull.
What are the causes of loss of consciousness?
Common causes of decreased consciousness include:
- substance abuse.
- certain medications.
- low blood sugar.
- lack of oxygen to the brain.
What happens if the brain is without oxygen for 20 minutes?
When a brain goes an extended period with a lack of oxygen, neural cells begin to die through a process called apoptosis. Although some brain cell death usually occurs throughout a person’s life, large numbers of brain cells dying simultaneously can result in diminished brain function or brain death.
How long brain can survive without blood?
After three minutes, global cerebral ischemia —the lack of blood flow to the entire brain—can lead to brain injury that gets progressively worse. By nine minutes, severe and permanent brain damage is likely. After 10 minutes, the chances of survival are low.
How long can you go without oxygen before dying?
Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later. Machines called automated external defibrillators (AEDs) can be found in many public places, and are available for home use.
Which term is also known as a runny nose?
The terms ” rhinorrhea” and “rhinitis” are often used to refer to a runny nose. Rhinorrhea actually refers to a thin, mostly clear nasal discharge. Rhinitis refers to the inflammation of nasal tissues. Rhinitis often results in a runny nose.
