BACKGROUND Lightweight portable oxygen systems are commonly preferred by patients over compressed-oxygen systems that use E-size cylinders. However, cost is often perceived as a barrier to the prescription of lightweight portable oxygen systems. OBJECTIVE To compare the overall health-care costs of patients with COPD who used lightweight portable oxygen systems to those who used E-cylinder sy...
BACKGROUND Portable oxygen devices simplify and facilitate patient therapy. This study was designed to compare S(pO2) and patient satisfaction with a portable oxygen concentrator or a combined system consisting of a fixed device with continuous-flow oxygen dispensation and a portable device with pulse dispensation for ambulation. METHODS This crossover trial assessed 25 subjects with COPD (92...
Ultrasonic testing systems have been extensively used in medical imaging and non-destructive testing applications. Generally, these systems aim at a particular application or target material. To make these systems portable and more adaptable to the test environments, this study presents a reconfigurable ultrasonic testing system (RUTS), which possesses dynamic reconfiguration capabilities. RUTS...
In this study, we have developed a prototype of a portable electronic nose (E-Nose) comprising a sensor array of eight commercially available sensors, a data acquisition interface PCB, and a microprocessor. Verification software was developed to verify system functions. Experimental results indicate that the proposed system prototype is able to identify the fragrance of three fruits, namely lem...
