Nettet20. jun. 2015 · We study Whittaker coefficients for maximal parabolic Eisenstein series on metaplectic covers of split reductive groups. By the theory of Eisenstein series these coefficients have meromorphic continuation and functional equation. However they are not Eulerian and the standard methods to compute them in the reductive case do not apply … NettetTo analyze whether there is a good correlation between the pressure setting by autoCPAP and the one calculated by mathematical prediction formulas proposed by Hoffstein et …

Nettet1. mai 2013 · Background: The Hoffstein formula is the most widely used equation to predict optimal CPAP pressure in patients with obstructive sleep apnea, but it is based on data from white patients.The purpose of this study was to develop an equation for optimal CPAP based on data from Asian patients, and to compare this new formula with the … NettetAll patients who had been titrated by autoCPAP [determining in one single night and using p90 pressure] were included. Two equations were used: Hoffstein [CPAP= (BMI x 0.16)+ (NC x 0.13) (AHI x 0.04) – 5.12] and Series [CPAP= (BMI x 0.193) + (NC x 0.07) + (AHI x 0.02) – 0.611]. RESULTS 619 patients were included.
