What is the formula mass of CaO?
This is calcium peroxide. You have to be careful... one might be tempted to call this calcium oxide, but oxygen normally has a charge of 2-, and since Ca always forms Ca2+, this is not calcium oxide because its formula would be CaO (Ca2+ and O2-). So the anion here is O22-, which is the polyatomic anion peroxide. ***************************************************************** The above response may be what you're looking for, but being in the medical profession, I see CaO2 as the formula to calculate Content of arterial oxygen. Therefore, the formula for this is: (Hb x 1.34 x %SaO2) + (PaO2 x 0.003) PaO2 should be in decimal form, PaO2 you can obtain from the ABG.
What is the difference between SpO2 and PaO2?
PaO2-- measure oxygen (O2) in blood. Normal range (80-100 mmHg) SaO2-- measure as a percentage the amount of hemoglobin molecules which are oxgenated (oxyhemoglobin) in arterial blood. Normal range (>95%)
What is normal value for SAO2?
90%
What is the difference between sp02 and sa02?
Both are measurements of the saturation of hemoglobin with oxygen in arterial blood.The difference is how the measurement is taken SpO2 is an indirect measurement using a finger probe, ear sensor or similar device. SaO2 is a direct measurement using a blood sample such as an arterial blood gas analysis.
What is oxygen content of the body?
Oxygen content in the body refers to the amount of oxygen present in the blood. This is measured as arterial oxygen saturation (SaO2) or oxygen partial pressure (PaO2). Adequate oxygen content is vital for proper functioning of organs and tissues in the body.
Types of cyanosis?
Cyanosis is the bluish discoloration of the skin or mucous membranes. It is divided into two types: Peripheral cyanosis: This is the bluish discoloration of the distal extremities like the fingertips, hands, toes, and lips that occurs when there is a lack of oxygen-rich blood flow to these areas. This can be due to cold temperatures, peripheral vasoconstriction, or peripheral vascular diseases. Here, arterial oxygen saturation (SaO2) is Normal. Central cyanosis: This is a generalized bluish discoloration of the body and the visible mucous membranes that occurs due to inadequate oxygenation caused by the presence of abnormal hemoglobin or reduced arterial oxygen saturation (SaO2). This could be due to problems of the Heart, Lungs, or Blood.
At what percentage of 0xygen does unconsciousness occur?
You can be unconcious and have a SaO2 of 100%.... but say your having difficultys breathing, if your O2 level drops below 94% Oxygen is needed, about 15% on a Nasal Canula. But if your passing out due to lack of O2, then it would have to be down around 85-90% but mind you.. that's not good. Plus, you cannot hold your breath and bring your O2 levels down. You will on the otherhand pass out if you hold your breath too long, not because your O2 levels are low, but because your body takes over so it can make itself breath again. Sometimes, your body can outsmart you.
If PAO2 is low and bicarb is low what is the problem?
Low partial pressure of oxygen (PaO2) and low bicarbonate levels can indicate respiratory acidosis, which is caused by inadequate breathing resulting in retention of carbon dioxide in the blood. This can lead to an imbalance in the body's pH levels and cause symptoms like shortness of breath and confusion. Treatment involves addressing the underlying cause of the respiratory impairment and providing oxygen therapy if necessary.

What is a normal blood oxygenation level?
Normal oxygen level of the earth's atmosphere is 21.5%. An oxygen deficient atmosphere is anything below 19.5%. Oxygen enriched atmospheres are 22.5% or greater (explosion hazard in the emergency responder arena).
Blood gases?
DefinitionBlood gases is a measurement of how much oxygen and carbon dioxide is in your blood. It also determines the acidity (pH) of your blood.Alternative NamesArterial blood gas analysis; ABGHow the test is performedUsually, blood is taken from an artery. The blood may be collected from the radial artery in the wrist, the femoral artery in the groin, or the brachial artery in the arm.The health care provider may test circulation to the hand before taking a sample of blood from the wrist area.The health care provider will insert a small needle through the skin into the artery. You can choose to have numbing medicine (anesthesia) applied to the site before the test begins.In rare cases, blood from a vein may be used.After the blood is taken, pressure is applied to the site for a few minutes to stop the bleeding. The health care provider will watch the site for signs of bleeding or circulation problems.The sample must be quickly sent to a laboratory for analysis to ensure accurate results.How to prepare for the testThere is no special preparation. If you are on oxygen therapy, the oxygen concentration must remain constant for 20 minutes before the test.How the test will feelYou may feel brief cramping or throbbing at the puncture site.Why the test is performedThe test is used to evaluate respiratory diseases and conditions that affect the lungs. It helps determine the effectiveness of oxygen therapy. The test also provides information about the body's acid/base balance, which can reveal important clues about lung and kidney function and the body's general metabolic state.See also:AcidosisDiabetic ketoacidosisLactic acidosisMetabolic acidosisRespiratory acidosisRespiratory alkalosisNormal ValuesValues at sea level:Partial pressure of oxygen (PaO2) - 75 - 100 mmHgPartial pressure of carbon dioxide (PaCO2) - 35 - 45 mmHgA pH of 7.35 - 7.45Oxygen saturation (SaO2) - 94 - 100%Bicarbonate - (HCO3) - 22 - 26 mEq/LNote: mEq/L = milliequivalents per liter; mmHg = millimeters of mercuryAt altitudes of 3,000 feet and above, the oxygen values are lower.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAbnormal results may be due to lung, kidney, or metabolic diseases. Head or neck injuries or other injuries that affect breathing can also lead to abnormal results.What the risks areThere is very little risk when the procedure is done correctly. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.Other risks associated with this test may include:Bleeding at the puncture siteBlood flow problems at puncture site (rare)Bruising at the puncture siteDelayed bleeding at the puncture siteFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)Special considerationsTell your health care provider if you notice bleeding, bruising, numbness, tingling, or discoloration at the puncture site. Also let your doctor know if you are taking any blood-thinning medications (anticoagulants) or aspirin.ReferencesGold WG. Pulmonary function testing.
