What would you diagnose a pt who has a WBC count of 13.7, co2 of 140 on abg, & bilateral lung infiltrates; placed on a ventilator. Pneumonia, or asrd?
Yes but...: An arterial blood gas (abg) can be performed awake or asleep. This can be a somewhat painful blood test and one would likely not be able to stay asleep while being performed. However, this can be done on a sedated patient or one who has an catheter for access to the the arterial blood system. ...Read more
See below: An arterial blood gas (abg) is used to detect the oxygenation in blood and see if there is any discrepancy to that obtained from the lungs (via a finger or ear oxygen sensor). If so, it could be something like a blood clot in the lungs. It also tells you your carbon dioxide level and blood acidity. You can refuse any test you want. ...Read more
Yes: Also add pao2 level. The most important are ph, paco2, and pao2. ...Read more
Follow equipment: An abg (arterial blood gas) is a specialized type of blood draw from an artery, so you need an experienced medical professional with training/experience. This lab is usually run immediately for accuracy, so it needs to be done on site where there is a blood gas machine. Places that might have this would be doctor's offices or clinics, pulmonary labs, labs, hospitals, ers, instant care facilities. ...Read moreSee 1 more doctor answer
Depends: It depends on the reason why the patient was placed on the ventilator in the first place and how they respond. Sometimes an abg is obtained only a few minutes after being placed on a ventilator (e.g. After an emergency intubation); often, an abg is not needed at all (e.g. Intubated for an elective procedure requiring general anesthesia). ...Read more
Can a patients 02sat be in the high 90's while the patients abg shows a po2 in the 50's? And what could cause this?
Huh?: I would suggest you discuss you needs with your medical doctor. ...Read more
Interesting question: If you ask me, most if not all such patients should get abgs. Physicians practice differently though and not all do this. There are no hard guidelines and standard of care for that as far as I am aware, unless the patient is in respiratory failure/intubated where abgs guide the management. ...Read moreSee 2 more doctor answers
Not really: Estimating the pO2 would be very inaccurate, especially if its from a venous sample. There is no way to tell what your arterial level is based on the venous level. ...Read more

About 15 years ago they did scalp and abg gases on my baby. I never got interpretation from the nurses and doctors in the room. Why?
Please help me figure out how to determine compensated, partially compensated and fully compensated abg's. I am ok with identifying pH, resp and metabolic acidosis and alkalosis, and oxygenation but when giving my final answer, I just can't put it togethe
ABGs: Look up ABG nomogram and how to read them and that should help. ...Read more
Acidosis/alkalosis: Abg provides important additional information about carbon dioxide levels and acid base disorders. Crucial information in successfully managing critically ill patients. Pulse ox only gives info on oxygenation, and even this is better assessed with abg. ...Read more
