Capnography and Oxygenation

SS of Capnography and OxygenationOxygenation and ventilation are cornerstones to your patient’s care.  We already know that we want pulse oximetry to remain at 94% or better, and capnography should sit between 35 to 45 mmHg.  But do we REALLY know what we’re looking at, and how can we use our tools to the best advantage?

After completing this education, you should be able to answer those age-old questions about your patient… is this COPD or CHF?  Is my endotracheal tube in the gut?  Is sedation wearing off?  Does my tube have a cuff leak?  How bad is my asthma patient… really? Is something kinked?  Even “my patient refuses to let me remove that awful black nail polish” – can I still use pulse oximetry?

Learn all this (and of course, more) through this CE.
