Introduction Blood pressure (BP) is one of the important vital signs that need to be monitored for personal healthcare. Arterial blood pressure is estimated from pulse transit time (PTT). This study uses two pulse sensors to get PTT. The aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. Materials and M...

the purpose of this study was to determine and compare blood lactate, heart rate and blood pressure responses in arm and leg exercises and to determine the relationship between these variables and fatigue time during these two modes of exercises. 8 young professional karate players (mean age 18.90±2.20) volunteered to participate in this study. the subjects completed two ergometers: arm and leg...

background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...
