Oxygen Rich Blood And 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

Systemic: The lungs oxygenate the blood then return it to the heart to be pumped to the body. ...Read more
Which component of health-related fitness increases the ability of the heart and lungs to deliver oxygen rich blood to the muscles?
Have unrepaired ASD; tingling&numbness in fingers when pulse is below 90, in feet below 80, now moving to face. Is this due to poor blood flow/O2?
Asd: These would be unusual symptoms for ASD or for heart rates under 80. This type of generalized parasthesiae can be due to deficiencies in vitamin B12, magnesium, calcium, potassium or types of neuropathy. Discuss this with your physician who will order the appropriate tests and/or refer you to a neurologist. ...Read more
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
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
Not really: If it is a nonsmoker, then no, should be 95%+ as "normal." lower can indicate lung infection or function abnormality. Smokers or persons with lung diseases often have lower saturations like this. If no explanation, should see dr for exam and probably chest xray ; breathing treatment (s). ...Read more
Depends: On your age and condition. It is usually reported by%. For example a little baby you would want to be high, close to 100% and if sick not lower than 92% when ill and hospitalized. A normal person walking around is usually 96- 100%. If a person has a chronic lung condition lower percentages of oxygen are acceptable, down to about 88%. ...Read more
Pulse: Oximetry measuring oxygen carrying capacity in per cent has replaced counting respiration in vital signs. 90% is low, but it indicates that you might need to find out why. The instantaneous level may or may not be associated with feelings of dyspnea. Chronic low o2 and desaturation can lead to pulmonary hypertension = lasting damage, . ...Read more
Red blood cells: Your red blood cells carry oxygen to your body. Red blood cells are packed with an iron containing protein called hemoglobin that can bind oxygen in your lungs and carry it to every cell in your body. In the tissues, oxygen leaves hemoglobin in part because of the acidic environment, called the Bohr effect, and carbon dioxide is bound by hemoglobin to carry to the lungs where you breathe it out ...Read more
No: Not unless other factors.Get a more detailed answer ›
Ambient air is about: 21% o2, and healthy lungs produce a po2 of 80-100%. Babies in nicu's treated with 100% due to respiratory immaturity could get pulmonarty and retro lentar fibrosis. One does not do well with higher levels of o2. Like goldylocks, not too little, not too much: just right. ...Read more
What is normal levels of oxygen in the blood? What is considered low and what is considered dangerous? Is levels in the 80s ok?
It is low: If you are asking about oxygen saturation the level should be above 90%. Normally it it is 97 - 99%. If the levels are in the low 80s - the person should be on oxygen. The oxygen saturation is obtained via external device placed on the finger or earlobe. If you obtain arterial blood and measure oxygen level - po2 the level in 80 is ok. ...Read more
96% or higher: Normal is 96% or above on room air ...Read more
The air we breathe in has about 21% oxygen. It reaches deep in the lung and permeates the lining of the lung and blood vessels and dissolves in the liquid part of blood. From the liquid part of blood, it binds hemoglobin in the red cells. The red cells carry the oxygen for use by all organs in the body.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk prodFor good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats.
