متن کاملComparison of Various Blood Pressure Measurement Techniques with Standard Office Based Blood Pressure Mesurement
Introduction: In order to control Hypertension, it is necessary to understand the methods of blood pressure measurement. Recent guidelines emphasize on employing appropriate blood pressure measurement techniques and white coat hypertension. Definition and methods of blood pressure measurement have changed in the American guideline based on SPRINT trial (Systolic Blood Pressure Intervention Tria...
متن کاملComparison of Intra-abdominal Pressure Measurement and Physical Exam for Diagnosis of Surgery Indication in Patients with Abdominal Compartment Syndrome due to Blunt Trauma
Background & Aims: Increase in abdominal pressure can lead to the so-called intra–abdominal compartment syndrome (ACS) that is often observed during the first 24 hours after sever abdominal trauma and surgery. Measurement of the intra abdominal pressure through the bladder as a non-invasive measurement can provide a quick and accurate assessment of abdominal pressure changes. This study was per...
متن کاملAn Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams
This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
متن کاملDesign and Simulation of piezorestive pressure sensor for AFM Probe the displacement measurement
investigating pressure applied in surface vertically that is done by use of mechanical procedures isn’t efficient to measure pressure applied in inner surface of reservoir or pipes having gas due to entering pressure into whole walls and different surfaces. So, in order to measure this kind of pressure, several studies were conducted in past decades and also various procedures were proposed tha...
