From: Hemodynamic monitoring and management in patients undergoing high risk surgery: a survey among North American and European anesthesiologists

  ASA Respondents (n = 157) ESA Respondents (n = 142)
Answer Options Response Percent Response Percent
I use dynamic parameters of fluid responsiveness (Pulse Pressure Variations, Systolic Pressure Variations, Plethysmographic Waveform Variations) as surrogates for cardiac output monitoring 54.1% 60.6%
Available cardiac output monitoring solutions are too invasive 48.4% 26.8%
Cardiac output monitoring does not provide any additional clinically relevant information in this setting 24.2% 14.1%
I use SvO2 and/or ScVO2 as surrogates for cardiac output monitoring 13.4% 26.1%
Available cardiac output monitoring solutions are unreliable 8.3% 15.5%
