Non-Invasive Estimation of Systolic Blood Pressure and Diastolic Blood Pressure Using Photoplethysmograph Components

PURPOSE Photoplethysmography (PPG) is a noninvasive optical technology that detects changes in blood volume in the vascular system. This study aimed to investigate the possibilities of monitoring the cardiovascular system status by using PPG. MATERIALS AND METHODS Forced hemodynamic changes were induced using cardiac stimulants; dopamine and epinephrine, and PPG components were recorded by a ...

Non Invasive Estimation of End-systolic Blood Pressure in Babies

Conventional measurements of systolic cardiac function and cardiac output may be influenced by loading conditions. The presence of extra-cardiac shunts in the transitional circulation limits the application of such measures in a neonatal population. An accurate method to assess neonatal myocardial function is required that takes account of cardiac loading conditions. One option is to correlate ...

Non Invasive Blood Pressure

Alongside heart rate, Blood Pressure is one of the physiological parameters which has been measured by clinicians for the longest period of time: it was known to be important in the 16 century. It remains one of the most important physiological indicators to date and is also one of the more awkward parameters to measure. As has been discussed, blood is pumped round the body by the heart. The bl...

Heart rate and blood pressure estimation from compressively sensed photoplethysmograph

In this paper we consider the problem of low power SpO2 sensors for acquiring Photoplethysmograph (PPG) signals. Most of the power in SpO2 sensors goes to lighting red and infra-red LEDs. We use compressive sensing to lower the amount of time LEDs are lit, thereby reducing the signal acquisition power. We observe power savings by a factor that is comparable to the sampling rate. At the receiver...

[Systolic and diastolic blood pressure levels of healthy newborn infants]

OBJECTIVE: To identify normative blood pressure (BP) levels for Brazilian newborn infants and to define a cut-off point for high systolic and diastolic BP in this population.METHODS: 634 healthy term neonates, aged 12 to 36 hours, who were born in the Instituto Materno Infantil de Pernambuco (IMIP) were included in this survey. An oscillometric method was used to acess the neonates BP. To ident...
