To explore the characteristics of postural blood pressure changes in elderly inpatients and the related factors of orthostatic hypotension (OH). This study was a clinical case control study. Two hundred and sixty-six elderly patients (≥60 years old), who were hospitalized between April 2016 and November 2017 in Geriatric Department of Peking University First Hospital, were included. They were divided into direct standing group and indirect standing group. Direct standing group involved 102 patients, they changed posture from supine directly to standing position, and the blood pressures at the moments of supine, immediately after standing and the first, second, and third minute after standing were recorded by continuous noninvasive arterial pressure (CNAP) system. Indirect standing group involved 164 patients, and they changed posture from supine to sitting for 3 minutes, and then changed to standing position. Blood pressures at the moments of supine, immediately after sitting, the third minute after sitting,
