Oxygen (Definition)

Oxygen is a gas that the cells in your body need to work properly. The air we breathe normally has 21% oxygen. A maximum of 100% oxygen can be given. Babies with heart or lung problems may need ...Read more

Can you die from to much oxygen?

Can you die from to much oxygen?

Oxygen Toxicity: Normal room air is 21% oxygen. That will not hurt you. Diving with 100% oxygen can cause some respiratory problems. Prematures on extra oxygen can develop serious eye problems. Hyperbaric oxygen, for a long time (maybe 12 hrs or more) can hurt you. Most of these situations will not kill you. Also severe fires are accelerated by excess oxygen, so smoking on oxygen has killed people. ...Read more

Why is too much oxygen dangerous?

Oxygen toxicity: Hyperoxia likely exists whenever oxygen tension exceeds 21% of atmospheric pressure. It appears to produce cellular injury through increased production of reactive oxygen species, such as hydrogen peroxide, superoxide anion, and hydroxyl radical. Oxygen toxicity refers most commonly to resulting tracheobronchial injury and damage to the tissue of the lungs. ...Read more

How do I use oxygen at home?

How do I use oxygen at home?

Depends on need: A person generally must be tested to qualify for home oxygen use. If tested, this usually determines your need. You may need it only at bedtime. You may need it only when active or 24 hours a day if you have certain health conditions (usually heart or lung disease). Oxygen can be in a tank, canister, or home oxygen concentrator that connects to the nose, mouth, or face with tubing. ...Read more

Is blood oxygen level 93 ok?

It depends: If you live at sea level, and the pulse oximetry machine if functioning normally, your arterial oxygen saturation should be higher than 93%. If you live at high altitude, the partial pressure of oxygen in the air is lower and, depending on how high you are, an oxygen saturation level of 93% may be normal. ...Read more

What is the oxygen poor blood?

What is the oxygen poor blood?

Few basic reasons: Haemoglobin- a protein molecule, carries o2 in the blood vs called arteries and after o2 is used by tissues, the deoxyg. Hb is carried by vessels called veins -> heart -> lungs to get new o2 molec. Added. When hb is low in quantity or abnl.In str-> o2 is low in blood. Iron, folate, (folic acid) B12 deficiency- anemia o2 defective basic str.As in thalssemia, sicklecell dz. 2.Heart defects->mixing a &venous bloo. ...Read more

How does your baby use oxygen?

How does your baby use oxygen?

OXYGEN for ENERGY: Biochemically, oxygen (o2) is required for energy production for every living cell. Oxygen is transported by the blood bound to hemoglobin (red pigment in red cells). Oxygen is then delivered to the cells via simple diffusion. Oxygen is taken up by the mitochondria of the cells where oxidation and phosporylation are coupled to make atp (energy molecule). Oxygen converted to h20 in process. ...Read more

Why does the body need oxygen?

Cellular respiration: Oxygen is a final electron acceptor in the mitochondrial electron transport system (ets), which is a component of cellular respiration. Cellular respiration is needed for the production of Adenosine triphosphate (atp), which is the energy currency of the body. It is needed for virtually all living functions, only one of which is muscle contraction. Cyanide kills by paralyzing ets. ...Read more

How can oxygen get in the Blood?

How can oxygen get in the Blood?

How it works: The process of oxygen getting into the blood goes like this. First we inhale air with oxygen in it. Little pockets in the lung called alveoli fill with the air and the oxygen diffuses into capillaries. This oxygenated blood then goes back to the heart where it is pumped around to the rest of the body. When it reaches capillary beds in our tissues the oxygen diffuses out into the tissues. ...Read more

Causes for low oxygen sats93-97%?

Causes for low oxygen sats93-97%?

Many possibilities: With a proper medical history one might make some good guesses. That along with a proper physical exam might help better explain. Blood work could possibly even help. Not uncommonly it is a combo of things age included. Generally, it is not a major issue as long as it remains above 90, but still if there has been a sudden change it warrants looking into further. ...Read more

What are the effects of low oxygen?

What are the effects of low oxygen?

Quite variable: The effects of "low oxygen" depend on the severity and duration, as well as any underlying lung, blood or heart disease. It is best to talk to your doctor, as it can be very mild or it can cause major problems, including strain on the heart, sleepiness, poor school or work performance and behavior issues. ...Read more

What fixes low oxygen level at night?

What fixes low oxygen level at night?

Depends on cause...: Most often, this is related to obstructive sleep apnea. This is when your airway becomes "floppy" while sleeping. The airway closes and no air can pass into the lungs. Therefore, the oxygen level drops. Using oxygen at night won't fix the problem if this is related to sleep apnea. You will need a special machine that increases the pressure in your airway while sleeping. See a sleep doctor. ...Read more

What's a low oxygen level in general?

What's a low oxygen level in general?

92 % plus....: In all patients, but certainly in post op patients, we'd like to see oxygen saturation of at least 92%. Supplemental oxygen may be necessary, at least for a short time. Good pulmonary toilet and breathing exercises are also employed. Good luck. ...Read more
