Thank you! This was a wonderful article and helped me with a PP presentation I'm putting together. Btw, I'm a Bob Page Groupie! I went to his 12 lead classs and slap the cap 4 years ago and have been hooked since. Took them both again 2 years (my company had him come in to do them!). I have also seen his lectures, at JEMS, on sleep apnea, seizures and backboarding. The man is a genius!
Great resource. Bob Page was my paramedic instructor and when it comes to 12-leads and capnography, the man knows his stuff. Great teacher and great entertainer.
Anxiety is a part of life for everyone. It is quite normal to feel anxious over certain circumstances however it becomes a problem when a person is anxious over seemingly small, trivial or non existent factors. This is known as an Anxiety Disorder and is a recognized mental illness. http://www.xanax-effects.com/
Great job: I especially enjoyed the excerpts from medical journals. Everything was relevant to the Medic's (as opposed to the anesthesiologist's) world, and that saved a lot of time. I'm definitely telling others in the field about your blog!
"Continuous Wave Form Capnography Versus Colorimetric Capnography
In colorimetric capnography a filter attached to an ET tube changes color from purple to yellow when it detects carbon dioxide. This device has several drawbacks when compared to waveform capnography. It is not continuous, has no waveform, no number, no alarms, is easily contaminated, is hard to read in dark, and can give false readings.
Paramedics should encourage their services to equip them with continuous wave form capnography."
My question is this, Colorimetric devices are not considered true capnography devices, are they? Since capnography consists of both a constant numerical reading AND a wave form and the Colorimetric devices do not do either of those things, they cannot be considered a capnography devices. So after thinking this through I decided the Colorimetric must then be a capnometry device BUT the more I research capnometry readings they are also a continual numerical reading, which the Colorimetric is incapable of producing. Once the litmus paper in the Colorimetric device changes, there is no going back. Therefore, you cannot continue to use the Colorimetric device to ensure continually, proper ETT placement.
I'm sure you may be asking why I have been pondering these issues! Well, it all goes back to the ever present charting and correctly identifying the equipment utilized.
Please let me know your thoughts on this!
Thanks for putting together this material on capnography. Excellent info.
