Anesthesia Central is an all-in-one web and mobile solution for treating patients before, during, and after surgery. This collection of drug, procedures and test information is derived from Davis’s Drug, MGH Clinical Anesthesia Procedures, Pocket Guide to Diagnostic Tests, and MEDLINE Journals.

First Things First (assess & treat for the following)
- All mathematical calculations are adjuncts to clinical decision-making.
- Never substitute arithmetic for clinical judgment!
- If you did not personally collect the data on which you are basing these calculations, then be sure it was accurately obtained.
- Garbage in, garbage out, period!
- If the “numbers” suddenly change & they do not fit the clinical picture, then you should personally corroborate their accuracy BEFORE you base any therapies on these values.
- If you subject a pt to the risk of inserting a PA catheter, then you should personally look at the waveform tracings from the first set of “numbers” & be sure that you agree w/ the submitted values.
- If these data are to be of value, then you must interpret them in the context of dynamic pt care & you must understand the underlying physiologic principles.
- There is no one fixed hemodynamic value that remains the best value for that pt over an extended period of time.
