Stroke Volume Variation and Non-Invasive Cardiac Output Monitoring

Summary of interpretation of stroke volume variation

[@nguyenlongphuc1995]

thank you for making it comprehensive

[@madhavanp8623]

stroke volume increases during a positive pressure mechanical breath, it does not decrease

[@vwtiguan5848]

No, stroke volume increases during inspiration (positive pressure), but finnally decreases during expiration (due to drop RV preload)

How do you decided whether to use the NICOM or Flo Trac for a given patient?

[@ginaa3527]

Mamalama I believe if the patient has an A line you can use Flo Track compared to NICOM which is non invasive... they won't have an invasive line.

[@bong6370]

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.

Well the EV1000 (flotrac) also has a noninvasive option called Clearsight that is pretty awesome.
