Cerebral perfusion pressure (CPP) is the amount of pressure needed to maintain blood flow to the brain. CPP is regulated by two balanced opposing forces: Mean arterial pressure (MAP)is the driving force that pushes blood into the brain. Intracranial pressure (ICP) is the force that keeps bloo...
The example for using phoenix() on a data.frame in R has expressions for the PaO2: FiO2 ratio, SpO2: FiO2 ratio, respiratory support, vasoactive medications, mean arterial pressure (MAP), and fixed pupils. This example is provided to be explicit about data assumptions such as the SpO2: ...
Source data vector, the pressure of the systolic and diastolic, pulse pressure, heart rate interval, mean arterial pressure, maximum gradient of pressure rise during systole, the area under the systolic part of the pulse pressure wave, gender (male or female), including age, height, weight, ...
The source data vectors include one or more measurable or derivable parameters such as: systolic and diastolic pressure, pulse pressure, beat-to-beat interval, mean arterial pressure, maximal slope of the pressure rise during systole, the area under systolic part of the pulse pressure wave, ...
in addition, the end-expiratory CO concentration of the subject at an arbitrary point of time is calculated from the regression equations and the partial pressure of CO2in the arterial blood of the subject and the blood CO-Hb% is calculated from the mean value of the end-expiratory CO concen...
The goal of this study was to develop and validate a method to estimate EDV in humans non-invasively from left ventricular arterial coupling (Ees/Ea) and stroke volume (SV).MethodsEes/Ea can be calculated non-invasively from the four parameters of end-systolic arterial pressure (Pes), ...
which was closer to the prescribing cutoff score of 25 (both p<0.001, patient no. 1 vs no. 2, and patient no. 2 vs no. 3, Fisher exact test) All individual components of the score were correctly evaluated at least 80% of the time, except for mean arterial pressure, respiratory rate...
