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

High pth blood level but normal calcium blood level?

High pth blood level but normal calcium blood level?

PTH: Low vitamin d or a diet low in calcium can cause PTH elevation in the setting of normal calcium. Also kidney problems can cause a similar process due to difficulties processing vitamin d. ...Read more

Does blood sugar levels affect blood alcohol levels?

Does blood sugar levels affect blood alcohol levels?

Depends: If the blood sits around at room temperature and there is microbial contamination, fermentation of glucose could increase alcohol level. However, this is a very long scenario. ...Read more

Normal sugar blood level?

Normal sugar blood level?

100mg/dL or less: Physicians measure patient's fasting blood glucose. This is the blood sugar taken when the patient hasn't had food or drink for at least 8 hours. "normal" is considered to be 100mg/dl or less. There is a little leeway before a level is high enough to raise concern and necessitate intervention though. A non-fasting blood sugar - or random should be less than 150... Especially 2 hours after you eat. ...Read more

Is blood oxygen level 93 ok?

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

How would oxygen deprivation change arterial blood gas levels?

How would oxygen deprivation change arterial blood gas levels?

Breath rate increase: O2 deprivation will typically cause people to breath faster. Abg measures levels of oxygen, carbon dioxide and blood ph. Faster breathing causes a drop in co2 which then causes the blood to have an increase in ph (towards basic, not acidic). Over time, the body would compensate for this ph change via acid retention by the kidney and although the co2 would remain low, the ph would approach normal. ...Read more

Can blood transfusion causer lower creatinine level?

Can blood transfusion causer lower creatinine level?

Creatinine lowering: Yes, patients who need blood transfusion has a low volume in their intravascular (i) space. This causes an elevation of creatinine (c). When the blood is transfused and the i volume increases, the c will fall. It is similar to what happens to the c when a patient is dehydrated and is given fluid. ...Read more

Can hemodialysis affect blood glucose level?

Can hemodialysis affect blood glucose level?

Hemodialysis: Hemodialysis really should not affect your blood sugars. Insulin will last longer in your blood stream as kidneys fail so often Insulin requirements decrease with worsening kidney function. Peritoneal dialysis (where the fluid uses is high is dextrose aka sugar) can raise blood sugar levels. ...Read more

92% blood oxygen level, is this okay?

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

I need to know what's an optimal blood oxygen level?

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

My blood oxygen level is too low. What could happen if it got lower?

Low oxygen: Our body tissues needs constant supply of oxygen to perform optimally. If it gets too low then the tissues especially kidney, heart and brain would have ischemia and lot of problems. See pulmonary specialist. ...Read more

It seems whenever i exercise, the blood oxygen level drops. Will it get better if i exercise regularly?

Abnormal: It is not normal for your oxygen saturation (blood oxygen level) to drop with exercise. If this is occurring, you should be evaluated by a cardiologist or a pulmonologist who has expertise in the evaluation of people with exercise-related abnormalities. ...Read more

Low blood oxygen levels, at what number would be low enough to cause a person to fall to the floor and have a blackout?

Low blood oxygen levels, at what number would be low enough to cause a person to fall to the floor and have a blackout?

Depends: Its the rate of fall thats more important than the actual number. When the partial pressure of oxygen falls below 55 or 88% hemoglobin saturation the delivery of oxygen to our organs begins to decrease. If your organs, like the heart , is already damaged this drop can be very dangerous. If the organs are healthy they can tolerate this drop in oxygen levels for several minutes, sometimes even longe. ...Read more

When does low blood oxygen levels result in a coma? (I know it is under 74 because I was still sort of awake then although I suspect not much under.)

When does low blood oxygen levels result in a coma? (I know it is under 74 because I was still sort of awake then although I suspect not much under.)

Well this varies: This varies a bit from person to person, so there is not really a number. It sounds like you are talking about the pulse oximetry reading, right? This is not used to generate concern about a coma. The pulse ox reading varies and is somewhat inaccurate. For most people, having insufficient oxygen for over 5 minutes results in brain damage, which may cause a coma. ...Read more

Do good blood oxygen levels indicate a healthy heart?

Good enough: Normal blood oxygen saturation levels means nothing is immediately broken. That doesn't mean everything is in tip top shape. There are many pulmonary, cardiac, and hematologic causes of low blood oxygen levels and the "pulse ox" as we sometimes call it, helps us know when these conditions are getting better. ...Read more

For blood oxygen saturation level - what is the fatal and normal range?

Oxygen sat curve: If you look at the p50 or oxygen saturation curve, anything above 90% is ok for the hemoglobin to unload as it gets into the tissues and supply them. As the curve goes down to 75% about pao2 of 45, this nears the saturation in the veins where unloading of oxygen to the tissues including heart muscles becomes difficult and there will be eventual death as it gets lower than that. ...Read more
