The paper deals with an analysis of biosignals for the purpose of non-invasive blood pressure monitoring without the necessity of using a pneumatic cuff. The method of simultaneous recording of electrocardiogram (ECG) and photoplethysmogram (PPG) and evaluations of their mutual time shift, which corresponds to the pulse transit time (PTT), are described in the paper. Results of original and imp...
The use of smart phones in healthcare applications is growing steadily. The inbuilt sensors are used to estimate the value of physiological data from human body. With progressive innovation, smart phone based medical applications will continue to be developed at an exponential rate. In this paper, we show that a smart phone can be used to monitor the blood flow in finger, based on the pulse hei...
PURPOSE To assess systemic and ocular vascular reactivity in response to warm and cold provocation in untreated patients with primary open-angle glaucoma and normal control subjects. METHODS Twenty-four patients with primary open-angle glaucoma and 22 normal control subjects were subjected to a modified cold pressor test involving immersion of the right hand in 40 degrees C warm water followe...
Advanced hemodynamic monitoring is necessary for many patients with acute brain and/or spinal cord injury. Optimizing cerebral and systemic physiology requires multi-organ system function monitoring. Hemodynamic manipulations are cardinal among interventions to regulate cerebral perfusion pressure and cerebral blood flow. The pulmonary artery catheter is not any more the sole tool available; le...
Background: Hypertension is a common chronic disease with increasing prevalence worldwide. Regular close monitoring of blood pressure is key point of hypertension management. Home monitoring of blood pressure has its own problems such as lack of early access to a physician in case of emergency. In this study we have designed a device that could send the patient’s self-measured blood pre...
Background and purpose: The monitoring of the patients’ hemodynamic status and vital signs is a routine practice in ÏÇÜ and the use of a low-cost and soothing method to maintain stable physiological parameters is necessary. This study aimed at investigating the effect of music on the vital signs and SpÔ2 of patients after open heart surgery. Materials and methods: ...
Level of agreement between heart rate variability and pulse rate variability in healthy individuals.
BACKGROUND AND OBJECTIVE According to international standards, autonomic function is assessed by heart rate variability (HRV) calculated from R-R intervals obtained with an electrocardiogram (ECG). However, intra-operative movement artefacts and electrical interference may complicate R-wave detection. Pulse rate variability (PRV) derived from continuous blood pressure measurements may provide a...
Current treatment of diabetes in pregnancy relies on intermittent self-monitoring of blood glucoses using finger sticks to monitor capillary blood glucoses. Continuous glucose monitoring (CGM) systems are an emerging technology that allow frequent glucose measurements (every 5 min) and the ability to monitor glucose trends in real time. Although these devices are currently expensive and mildly ...
