Arterial blood gas

Common Questions and Answers about Arterial blood gas


Avatar_n_tn com/galecontent/blood-gas-analysis As for the difference between venous blood gas(VBG) and arterial blood gas, the oxygen saturation will be definitely higher in the arterial blood gas. However, in other elements it has been shown in studying patients with chronic obstructive lung disease that "VBG analysis can reliably predict the ABG values of pH, PCO2 and HCO3 in patients with chronic obstructive lung disease." (
Avatar_n_tn An Arterial blood gas (ABG) is a blood test that analyzes acid-base measurements of the blood and reveals information on the functioning of the lungs. This test provides more information than oximetry, which only measures oxygen saturation. Blood is drawn from an artery in the wrist and from this the following can be measured: 1) pH <7.35 indicates acidemia >7.
Avatar_n_tn A patient is having acute exacerbation of COPD. His arterial blood gas test results revealed an alkaline pH, low partial pressure of O2 and CO2, negative base excess and low level of actual bicarbonate level. HOw do i interprete these results? Is patient having acidosis or alkalosis?
Avatar_n_tn Thanks, w trout ------------------------------------------------------------------------------------ Dear W Trout Your arterial blood gas results are essentially normal. Hyperventilation, if you were hyperventilating at the time of the blood gas, does cause a lower pCO2. The trace regurgitation is nothing to worry about. The normal pulse oximetry excludes severe heart failure, but not milder degrees of heart failure - however your heart function on echo is normal. I hope this has been useful.
Avatar_n_tn I didn't see anything about arterial blood gases in the forum. My results from yesterday were: 7.38ph, 99 o2 sat, po2 103, 20.7o2ct, 15.6THb, 97.2oxyHGB, PCO2 45, HCO2 26. I've been told I don't have heart failure and am breathless from anxiety and maybe stomach reflux. If this is true shouldn't I have low Co2? How can I have high PO2 and high PCO2 at the same time. Does the 99 O2 sat indicate my heart isn't failing.
Avatar_m_tn The result from the blood test, which is called an arterial blood gas (ABG), of 55 mm Hg is a measure of gas pressure, like the pressure of air in your tires. This should be 90 to 100 mm Hg at sea level, so your result of 55 mm Hg is abnormally low. This discrepancy suggests that one of these measurements is wrong. Both the oximetry and the arterial blood gas determinations should be repeated, before the final decision is made on your oxygen needs.
Avatar_n_tn He said that there is a correlation between gas and Afib. That gas stimulates the vagus nerve. He advised me to take GasX. The problem for me is that it seems to help me temporarily, but ultimately causes me to become constipated. Then I have to take another pill.....and it goes on. Anyway, you are not "crazy". I have a friend younger than me that has AFib and she had a episode of Afib when she had food poisoning. The vomiting seemed to "kick it off".
Avatar_n_tn Referring to your post regarding A/Fib and bloated stomach/gas, I too have had the same experience. I believe it is a mechanical effect in that the gas inflates the intestine which in turn pushes on the vagus nerve or the bottom of the heart and triggers the A/F episode. The sensation is located under the left rib cage not in the chest. I can also induce A/F by swallowing something very cold on an empty stomach. This freaks out the nerve and the A/F proceeds.
Avatar_n_tn Hi! It sounds like you had an arterial blood draw -blood taken from an artery rather than a vein for specific tests like blood gas levels (usually for respiratory or cardiac workup issues)....
Avatar_f_tn The wrist is normally used for so called "ABG's" or arterial blood gas tests. Other venous blood draws should have no residual pain. The problem is often due to the patient used for a novice nurse or physician to get three required certification" ABG's. A properly performed ABG should leave no residual discomfort. Therein lies the rub. The procedure is difficult to perform.
Avatar_n_tn Hello Dear, Usually this kind of pain is caused by an incompetent taking an arterial blood gas sample. Healing may take weeks, perhaps months. You might try accupuncture ,TENS device. A TENS device relies upon the fact that the brain usually accepts one pain signal at a time. The TENS generates a mild electrical current somewhere else and the brain dismisses the signal from your actually damaged nerve. Sometimes the TENS works. Sometimes it doesn't.You should also consult a neurologist.
Avatar_m_tn Hi, i was wondering if trapped gas can cause chest soreness, chest tightness, shortness of breath, stabbing pain which is severe enough to think you are having a serious heart problem. and if the answer is yes, how does one go about solving this trapped gas problem? Thanks.
Avatar_n_tn Usually this kind of pain is caused by an incompetent taking an arterial blood gas sample from the wrist. You usually don't need this, but in teaching hospitals the turtles have to be certified in doing so many before they become adult turtles so they scam you and tell you "it's for your own good". Again, these injuries generally heal, but it will take weeks, perhaps months. You might try accupuncture or what is called a TENS device.
Avatar_n_tn Oxygen gets to the muscle via diffusion through the capillaries on the basis that a gas will flow from an area of high concentration, such as the arterial blood, to a zone of lower concentration, such as the muscle tissue. It is carried to the tissue by red blood cells, attached to the hemoglobin molecule on the red cell.
Avatar_m_tn I have no restriction in taking in air, have had 1 hr pulmonary testing, no asthma, have had arterial blood testing, and blood count (finger is 97, blood gas 67, gas exchange perfect, yet have been diagnosed with emphysema. Did have pneumonia (acquired from adverse reaction to overdose of zantac) productive cough yellow and green firsst, then after time changes to dark grey with spots. Was give salbutamol and atrovent, had violent reaction to medication.
Avatar_n_tn pH arterial, 7.46; PaCO2 arterial, 44.7; PaO2 arterial, 57.6; HCO3 arterial, 31.6; Base arterial, 7.3; O2 Sat arterial, 92; Pox Sat arterial, 91; CO HGB arterial 7.2; Critical value arterial, No. The ER was unable to give any explanations. Please note that prior to the above sleep lab study, I had taken a home noctural pulse oximetry test with similar drop in in O2Sat. I also had two pulmonary clots in 2007. Any answers, suggestions?

Avatar_n_tn I suspect that your mother had a test called an arterial blood gas performed to determine the oxygen saturation of her blood. Normal oxygen saturations are > 92%. If her saturation was 99-100%, that would still be considered normal. Alternatively, it could be that she has an elevated hemoglobin concentration in her blood which could be related to chronic smoking. I hope you find this information useful. Information provided in the heart forum is for general purposes only.
Avatar_n_tn The exception is when an arterial blood gas is drawn by a student in the wrist. I had one done on me by a novice and I had numbness for three months! On the top of the hand a so-called "butterfly" is generally used and it is inserted at a shallow angle and normally wouldn't be touching any major nerves. The needle doesn't stay in. A plastic catheter is run in over the needle. Rub the top of your hand with a little cortisone cream, soak in hot water with epsom salts.
Avatar_n_tn PHOSGENE GAS was formed by accident and three people were gassed by two pounds of gas burning in a confined kitchen sarea. [Similar to World War I gas] Lungs damaged 2nd time.
Avatar_n_tn Consult a physician for the needful assessment so that any serious illness is screened and caught early for prompt management. Investigation would include chest xray or CT chest, blood tests, arterial blood gas analysis,spirometry, ecg, echo, assessment of effort tolerance. Hope this helps. Take care.

Avatar_n_tn 25 percent will warrants the oxygen therapy), acid-base status on (preferably arterial) blood gas. Narcolepsy is associated with excessive daytime sleepiness. In this condition there will be ÔÇťautomatic behavior" such as driving past a highway exit or writing off a page, with no memory of the previous few minutes. You need to undergo tests like Polysomnography, Multiple Sleep Latency Test and CSF levels of Orexin/Hypocretin which help to substantiate the diagnosis.
Avatar_n_tn Oxygen saturation (SaO2) can be measured by an oximeter as well as by an arterial blood gas. At sea level the normal oxygen level is 95 mm Hg to 100 mm Hg. An arterial blood gas is done to measure the oxygen level (PaO2), since it cannot be measured by an oximeter. At sea level the normal carbon dioxide level is 35 mm Hg to 45 mm Hg. Just like with the oxygen level, an arterial blood gas is done to measure the carbon dioxide level (PaCO2), since it cannot be measured by an oximeter.
Avatar_n_tn Could you please explain what these arterial blood gas test results mean? PO2 = 69 PCO2 = 67mmHg HCO3- = 33mEq/litre pH = 7.
Avatar_n_tn My mom had a pulse ox rate of 66% in the ER. They checked it several times to make sure with several machines. SHe was alert enough to ask about lunch. The staff said because she does not move around much she can survive on less oxygen.
Avatar_f_tn Have you been checked for vitamin deficiency?
4943237_tn?1428994695 Don't be afraid to tell someone if an injection or blood draw was painful or complement them when it was not. An arterial blood gas, drawn from the wrist, can be excruciatingly painful if not performed properly. It pays to look away or close your eyes.
Avatar_n_tn Oxygen levels can be monitored by Pulse oximetry, End-tidal carbon dioxide measurement, Transcutaneous CO2 measurement or Arterial blood gas/venous blood gas. Treatment with bronchodilators with inhaled corticosteroids in the form of nebulization will help. I suggest you to consult pediatrician for further management. Take care and regards.
Avatar_m_tn My oxygen levels, including my arterial blood gas test, was normal. My problem is that anytime I try to hold my breath at all, it feels like the "primal instinct" to breath takes over very powerfully almost instantly and I can't stop it...if I resist, I will get very lightheaded. I knew about this problem before, but I was having a CT scan to evaluate my hematuria and I couldn't hold my breath long enough. Can you tell me what this could be?
