Journal of Perinatology - The perfusion index derived from a pulse oximeter for predicting low superior vena cava flow in very low birth weight infants Skip to main content Thank you for visiting ...

Three perfusion CT parameters of hepatic perfusion index (HPI), mean transit time (MTT) and permeability-surface area product (PS) were compared among controls, patients and subgroups.

Overall, among those with normal perfusion, Masimo’s devices returned blood oxygen readings that differed from the comparative arterial blood gas measurements by an average of just 0.18%.

Masimo announced today the CE marking of the measurement of respiration rate from the pleth (RRp™) on the MightySat™ Rx fingertip pulse oximeter.
