Blood Pressure Measurement Device A New Solar-Powered Blood Pressure Measuring Device for Low-Resource Settings
Abstract—The management of high blood pressure (BP) is particularly inadequate in low-income countries, where the unavailability of a reliable, durable, and affordable BP-measurement device is a major obstacle to accurate diagnosis. Recognizing this, a World Health Organization committee was established to correct this deficiency by influencing manufacturers to produce a device according to pre...
متن کاملAn underwater blood pressure measuring device.
Measurement of arterial blood pressure is an important vital sign for monitoring the circulation. However, up to now no instrument has been available that enables the measurement of blood pressure underwater. The present paper details a novel, oscillometric, automatic digital blood pressure (BP) measurement device especially designed for this purpose. It consists mainly of analogue and digital ...
متن کاملVideos in clinical medicine. Positive-pressure ventilation with a face mask and a bag-valve device.
N Engl J Med 2007;357:e4. Copyright © 2007 Massachusetts Medical Society. Indications Providing positive-pressure ventilation with a face mask and a bag-valve device can be a lifesaving maneuver. Although seemingly simple, the technique requires an understanding of the airway anatomy, the equipment, and the indications. Face-mask ventilation is used in patients who have respiratory failure but ...
متن کاملTwin Plate Weir: A Flow Measuring Device (TECHNICAL NOTE)
For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...
متن کاملEvaluation of a community-based automated blood pressure measuring device.
BACKGROUND Automated devices are widely available in the community for people to measure their blood pressure. We assessed the accuracy and reproducibility of a brand of community-based automated device against the standard mercury sphygmomanometer. METHODS Same-arm pairs of blood pressure readings were obtained with the Vita-Stat 90550 automated device, a sphygmomanometer and the Omron HEM-7...
