Perfusion index in the preterm infant immediately after birth

Early Human Development, 2015
To evaluate PI in preterm infants during the first 10 min of life.An observational study was conducted in the delivery room on preterm infants (less than 32 week gestation). PI values were obtained from a pre ductal saturation probe placed on the right wrist.

Myocardial Perfusion Reserve Index in Children With Kawasaki Disease

Journal of Magnetic Resonance Imaging, 2017
BackgroundCoronary artery lesions in patients with Kawasaki disease (KD) can impair myocardial perfusion, yet evaluation of perfusion defects by cardiac magnetic resonance (MR) in children is often qualitative.PurposeIn this study we aimed to use a quantitative method of myocardial perfusion using stress cardiac MR‐derived myocardial perfusion reserve ...

Perfusion Pressure and the Papillary Perfusion Index in a Non-glaucomatous population

1984
Le prove clinico-sperimentali hanno messo in luce che nel meccanismo patogenetico del danno al nervo ottico nel glaucoma, l'equilibrio tra la pressione intraoculare e la pressione sistemica rappresenta un parametro importante. In una popolazione non glaucomatosa, selezionata con pressione intraoculare normale e valori sia normali che alti della ...

Pulse oximetry and perfusion index measurement to assess uterine perfusion and viability.

International surgery, 2006
This study was designed to establish if pulse oximetry (O2Sat) and perfusion index (PI) could be used to assess the contribution that uterine and ovarian vessels make to the overall perfusion of the uterus. During routine hysterectomies, the O2Sat and PI were measured over the right and left uterine cornu.

Heterogeneity of myocardial perfusion provides the physiological basis of perfusable tissue index.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1995
Assessment of viable from nonviable myocardium is critical for the care of patients being considered for revascularization procedures. Recently, the perfusable tissue index (PTI) has been proposed as an index of myocardial viability.Computer simulations were performed for homogeneously and heterogeneously perfused tissue over a wide range of flows (0 ...
