Normal Oxygen Level For Infants
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
Depends on age...: Pulse oximetry is a standard mechanism to determine fairly accurately (most of the time) the oxygen saturation of the blood. The desirable saturation level varies based on infant/child age and multiple other considerations such as chronic lung disease, heart defects, body temperature, etc. However, for most children most of the time, we prefer seeing the level in the mid to upper 90's. ...Read more
Erectile dysfunction: I see your main concern is erectile dysfunction at age 30. I am going to assume this is actually hemoglobin a1c levels; your blood hemoglobin is measured in different units. Your level is in the reference range and this rules out diabetes as the cause of your erectile dysfunction. Two causes that are often missed by physicians are prolactinoma ; hemochromatosis. Continue the workup, good luck. ...Read more
For what reason should patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?
My ferritin level is 5.5 starting range is 6.2-137.0 is this a considerably low level? My iron levels are within normal range.
Low iron stores: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your ferritin levels suggest low body stores of iron. Iron deficiency is common in women due to menstrual blood loss. You may take oral iron supplement with multivitamins and consult your doctor at the next visit. For 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. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
Possible for labs to measure LDH units differently? Child inexplicably ill for months w/normal CBC. LDH in the 600-700s. Dr: "not significantly high."
Non-specific marker: The LDH test is a non specific marker of inflammation in the body.The enzyme originates from several defined sites, including liver, blood, lungs, kidneys, muscle, etc and a further test could define which area is involved. If your kid has had a vague flu like illness with muscle pains, this may be within the expected findings of the doc. A followup test should show recovery ...Read moreSee 1 more doctor answer

To carry more oxygen: Fetal hemoglobin hangs on to oxygen tighter that adult hemoglobin. Therefore more red blood cells are needed to cary the amount of oxygen that can be delivered to the tissues. The blood in utero is very saturated at a lower oxygen tension. The fetal hemoglobin is needed in utero and is slowly replaced by adult hemoglobin after birth. ...Read more
Need for oxygen: in the womb. the high hemoglobin is needed to provide oxygen to the developing fetus. The hemoglobin also is very special in that it holds oxygen very well. Right after birth this HGB is replaced with a more needed regular HGB, that works better in an air environment. The breakdown of this large amount of hemoglobin can cause a problem with jaundice in some babies ...Read more
