In some cases, your healthcare professional may have trouble entering a suitable vein. Risks and side effects of a potassium test are the same as for any routine blood test. The test generally takes only a few minutes. The band and the needle will then be removed and the site will be covered with a small bandage. Blood will then be collected into a tube. You may feel a sting or the prick of the needle. Your healthcare professional will wrap a band around your upper arm to create pressure so that your veins swell.ДЄ needle will be inserted into your vein.

Ask your doctor for specific instructions prior to your test day.

Common causes are:ДЄ test result of high bicarbonate and low pH (less than 7.35) is a condition called respiratory acidosis.

prolonged lack of oxygen from severe anemia, heart failure, or shock.

Low bicarbonate (HCO3)ДЄ test result of low bicarbonate and low pH (less than 7.35) is a condition called metabolic acidosis. A substance is more alkaline when its blood pH measurement is greater than 7.45. A blood pH measurement less than 7.35 is considered acidic. Normal range from 7.35 to 7.45 is considered neutral. Typically, a blood is slightly basic with pH measurement of close to 7.4 in maintained by the body. Acidosis, on the other hand, is when your body fluids are too acidic. Alkalosis is when your body fluids are too alkaline. Blood pH is a measurement of acidity or alkalinity. The blood test often measures blood pH along with CO2 levels to further determine the cause of your symptoms. The normal range for CO2 is 23 to 29 mEq/L (milliequivalent units per liter of blood).

Arterial blood is usually taken from an artery in the wrist called the radial artery. This more complicated procedure is done by a practitioner trained to safely access arteries. Veins carry metabolic waste and deoxygenated blood to the lungs to be exhaled as carbon dioxide and to the kidneys to be passed in urine. A blood gas analysis requires arterial blood because the gases and pH levels in the arteries different from venous blood (blood from a vein).ДЄrteries carry oxygen throughout the body. covers the puncture wound with sterile gauze to stop any bleedingД«lood gas analysis is often a part of the CO2 test.removes the elastic band and the needle.gently inserts a needle into the vein and collect blood in the attached tube until it is full.wraps an elastic band around your upper arm to cause the vein to swell with blood.cleans the site (often the inside of the elbow) with a germ-killing antiseptic.

To get a venipuncture blood sample, a healthcare provider: Your doctor will order a simple venipuncture blood sample if they only want to measure HCO3. Venipuncture is the term used to describe a basic blood sample taken from a vein. Blood samples for a CO2 blood test may be taken from either a vein or an artery.
