NettetSeries equation correlated better with autoCPAP pressure than Hoffstein equation. Despite average pressure was similar to that of autoCPAP (9.9 vs 9.6) a high internal dispersion was found. Correlation did not improve when pressures were divided into groups (<8, 8-12, >12). Nettet17. des. 2012 · Using the Series equation, my predicted pressure is 12.8 cm. Using the Hoffstein equation, my predicted pressure is 12.1 cm. My sleep doctor recommended a fixed CPAP pressure of 15 cm. Using my autoset in apap mode (13 to 17 cm range), the median pressure was 14.9 cm and 95% pressure was 16.9 cm.
