in the -ve predictive value slide you wrote FN/(TN+FN) and in your calculation you divided the TN=82 not the FN=4 !! also in the effect of prevalence slide there are many mistakes 1st the specificity is = 93.3% not 96% 2nd the NPV according to your last slid it is equal to 37.8% not 62%
Mamalama...Gina A is right Flo Track requires an A-line to get your SVV, SVI, CO,CI results. But it will need a CVP line for SVR, SVRI. A good A-line is a must because if your A-Line is "positional", the results are not reliable. With NICOM, A-Line is not required. Prepping the skin is an absolute necessity for NICOM.
