Should We Ignore What We Cannot Measure? How Non-Uniform Stretch, Non-Uniform Wall Thickness and Minor Side Branches Affect Computational Aortic Biomechanics in Mice

How should we measure and report elasticity in aortic tissue?

BACKGROUND Different stress-strain definitions are used in the literature to measure the elastic modulus in aortic tissue. There is no agreement as to which stress-strain definition should be implemented. The purpose of this study is to show how different results are given by the various definitions of stress-strain used and to recommend a specific definition when testing aortic tissues. METH...

Functional measures, Part 1: What is function, what should we measure, and how should we measure it?

O ccupational therapists, physical therapists, nurses, social workers, psychologists, and physicians all share a common concern with promoting functional independence of their clients. In addition, members of each profession might administer functional assessments or implement interventions intended to enhance the functional independence of their clients. This often makes us uneasy or results i...

PEEP and Mechanical Ventilation: We Are Warned, We Cannot Ignore.

of the Ventumask and EasyVent, Ventukit, and EveCoulisse are very similar, respectively, whereas the Boussignac is the least expensive. However, based on the results of our study, the Boussignac device appears to perform more as a reservoir mask than as a CPAP device because of the low variable end-expiratory pressure, low airflow outputs, and high unadjustable FIO2. We concur with Drs Salturk ...

Erythema nodosum :what should we consider about it?

Sympathovagal balance: how should we measure it?

There are complex interactions between the sympathetic and parasympathetic nervous system inputs to the sinus node. The concept of "sympathovagal balance" reflects the autonomic state resulting from the sympathetic and parasympathetic influences. Despite widespread usage of a variety of heart rate (HR) variability parameters as indexes of sympathovagal balance, no index has been validated as a ...
