CONTACT PRESSURE MEASUREMENT
… techniques do not indicate the actual gasket pressure in the interfaces of the joint. An extensive literature survey was carried out to identify suitable sensing material that could be configured into a miniature sensor to be inserted between the two interfaces of bolted joints for the purpose …

Reliability of Urinary Bladder Pressure Measurement in Critical Care
Background of the study: Intra abdominal pressure (IAP) theoretically may be a predictor of enteral nutrition tolerance (EN). Urinary bladder pressure (UBP) is the gold standard for estimating IAP. Current recommendations for UBP measurement (UBPM) calls for the instillation of normal sterile …

An exploration of through-the-eye intraocular pressure measurement device
Glaucoma, caused by an elevated intraocular pressure (IOP), is one of the leading causes of blindness. As constant monitoring of IOP is essential in the treatment of glaucoma, the IOP measurement techniques described in patents and patent applications since 1950 are examined. None of the methods …

Novel design for foot pressure measurement using opto-electronics in rehabilitation
… uniaxial transducer for measuring the plantar pressure of the foot. The measurement approach used here is an optical system that could be incorporated between the foot and the shoe via an in sole. The information obtained can be used to assess the pressure and the kinetic variables that will …

Assessment of catheter-manometer systems used for invasive blood pressure measurement
Direct measurement of blood pressure using a fluid-filled catheter and an electromechanical transducer is widely accepted in clinical practice. However, errors associated with the measurement are often not appreciated and these catheter-manometer systems are frequently unable to accurately …

Optical Sensors for High-Temperature Pressure Measurement and Real-Time Particle Detection
… of optical sensors, one for high temperature pressure measurements and the other for real-time particle detection. With a high melting temperature (over 2000°C), low optical loss, and excellent corrosion resistance, sapphire (α-Al₂O₃) is ideal for high temperature sensing applications. …

Minimally Invasive Characterization and Intraocular Pressure Measurement via Numerical Simulation of Human Cornea
Finally, the proposed method is applied in the simulation of a particular type of refractive surgery, picosecond laser keratomileusis (PLK), and compared with reported clinical outcomes.

Comparing pressure measurement systems and a force platform as tools for equine gait analysis
… field use rather than a laboratory environment. Pressure measurement systems were designed for use in the human podiatric profession in order to provide a quick and easy method for determining vertical ground reaction forces, contact area and plantar pressures. Previous testing of the F-Mat …

Analysing the technique of blood pressure measurement in primary care: a single pilot study
Background: Accurate blood pressure (BP) measurement is essential for the diagnosis and management of hypertension. However, BP measurement technique is often suboptimal in primary healthcare facilities, potentially leading to misdiagnosis and inappropriate management. Objective: To assess the …

Suction pressure measurement and behavioral observations of sprawning-run sea lampreys (<i>Petromyzon marinus</i>)
… where lamprey attachment is a concern, this pressure-measurement method would be ideal for surface creation and testing. In the second experiment, sea lampreys displayed little preference among surfaces with varying levels of texture. Repeating this experiment in a high sheer environment may …

Survey of Knowledge of Fifty Registered Professional Nurses Regarding Selected Factors of Indirect Blood Pressure Measurement
… that contributed to variations in the indirect measurement of blood pressure. It was thought that assessment of the nurses' knowledge could contribute to more effective nursing services by disclosing areas of weakness which could be strengthened by hospital in-service and nursing education. …

The relative susceptibility of ferrous alloys to hydrogen embrittlement determined by effective electrolytic hydrogen pressure measurement
… characteristics and the effective hydrogen pressures developed at the charged surfaces were different. These results show that the typical hydrogen embrittlement test which uses cathodic charging at selected cathodic current densities to determine the relative susceptibility of different …
