Arterial Blood Gas (ABG) Tic-Tac-Toe Examples

[angelabangela18]

You're a lifesaver! This explanation took all the jitters out of my next Nursing test. I'll definitely be back for more.

[TaintedxHalo]

dude, you are a genius.

[MsTerryMayden]

Wow, I finally understood this! Thank you very much! :)

[russellfamilyfun]

THANK YOU SO MUCH!!!!!!!!!!!!!! My teacher is wanting the difference between partially compensated, fully compensated and without compensation.... Can you explain the difference between the three?

[survivenursing]

@russellfamilyfun In a nutshell: Uncompensated (without compensation) is when one value is abnormal, but the other is normal. Compensation is when there is one primary condition and the opposite system (either metabolic or respiratory) is compensating (so that value will be abnormal as well).

It is considered fully compensated if the compensatory system is able to bring the pH back into a normal range. It is considered partially compensated if it didn't quite bring the pH back to normal.

Hey, Thanks alot for this video it really helps alot, and for my whole nursing class too.

I tried to go to your website and it said it was expired. Are you going to continue?

[survivenursing]

@shawn0181 It should be working. Are you sure you entered the URL correctly? survivenursing (DOT) com

Same with number 3, and 5, i think there is more, but im gonna stop working these out for now. Confusing myself. Please help. I am sure its just a mistake?

[mnsnow902]

that question was for number 1

[mnsnow902]

I am confused. isnt PCO2 supposed to be 35-45 instead of 45-35? why would the CO2 go under alkalosis? the value thats listed is 24. Wouldnt that be acidic? Please help im confused

[bradhanson]

@mnsnow902 We think of the CO2 value as a respiratory ACID. Therefore, when the number is higher we have more acid and when the number is lower we have less acid (more alkaloid). The reason that the normal value of CO2 (35-45) is written as 45-35 is so that each edge of the chart will either represent the acid or alkaloid side of the range.

[bradhanson]

@mnsnow902 If we had the reference chart say 35-45 (which is a completely valid option) then you couldn’t use the side of the chart to determine whether it is an acid or a base. You would need to remember that CO2 is an ACID and that HCO3 is a BASE for every problem. You would know this anyway if you were able to create the chart, but a lot of people find it easier to visualize written as it is.

[bradhanson]

@mnsnow902 I explain this a bit better in the full ABG lecture which hasn’t been posted yet, but should be soon. If you’re still confused feel free to send a private message and I can explain things further.

[stoth86]

this is going to give me a heads up for class next week. am i doing something wrong on the website? I hit show answers and all that comes up is "visable" and i cannot get back to the original problem?!

[survivenursing]

@stoth86 This should be resolved now. There were some latent problems with Internet Explorer and Safari compatibility but everything should be working now.

Please try again and let us know if you have any further issues.

this is awesome!

[flubadub]

THIS REALLY MAKES IT EASY TO UNDERSTAND. THANKS

[dlhdung]

This helps me a lot. Thanks man. :)

[0326hkim]

by the way, is there ever a time when ph, co2, and hco3 are all on either acid or base side? or ph on acid side and co2 and bicarb on opposite, vice versa?

is there such thing as a combined acidosis? combined alkalosis?

[survivenursing]

@0326hkim It’s very conceivable. The examples here have clear solutions but occasionally you may find a clinical presentation that is atypical. In these cases you cannot apply a simple algorithm but rather must critically think to figure out what is actually going on.

[survivenursing]

@0326hkim Perhaps some questions you may ask yourself: What is the history of this patient? How long have they had a respiratory or metabolic issue (which one is older)? Is it possible to identify a precipitating event before either? Has trauma occurred? Why are their compensatory mechanisms not functioning correctly?

[survivenursing]

@0326hkim A better example to demonstrate the necessity of critical thinking is if the client had a pH of 7.40, but abnormal PaCO2 and HCO3. In this case, there is a chance one system is the abnormality while the other is fully compensating. In order to identify the underlying etiology you must look at the entire clinical picture by asking questions similar to the above. In this case, likely the condition that chronologically appeared first is the primary cause.

easiest way i learned ABGs ever. thank you

[kjrnms2]

This is great.
