Key result
Modelflow stroke volume from non-invasive finger pressure accurately estimated aortic flow during orthostatic stress, with a non-significant offset of 3+/-8 ml during 70-degree head-up tilt.
Why the study?
Does Modelflow accurately calculate stroke volume from non-invasive finger pressure compared to thermodilution under orthostatic stress in young adults?
Observational (n=10)

Accurately estimates stroke volume non-invasively during orthostasis; leaves open clinical translation pending larger validation studies.
Harms et al. (1999) conducted an observational in Orthostatic stress (n=10). Modelflow stroke volume from non-invasive finger pressure (FINAP) vs. Thermodilution-determined stroke volume (TDSV) was evaluated on Stroke volume offset compared to thermodilution during orthostatic stress (p=not significant). Modelflow stroke volume from non-invasive finger pressure accurately estimated aortic flow during orthostatic stress, with a non-significant offset of 3+/-8 ml during 70-degree head-up tilt.
