A portable centrifugal analyser for liver function screening.
Mortality rates of up to 50% have been reported after liver failure due to drug-induced hepatotoxicity and certain viral infections (Gao et al., 2008). These adverse conditions frequently affect HIV and tuberculosis patients on regular medication in resource-poor settings. Here, we report full integration of sample preparation with the read-out of a 5-parameter liver assay panel (LAP) on a port...
متن کاملValidation of a portable, waterproof blood pH analyser for elasmobranchs
Quantifying changes in blood chemistry in elasmobranchs can provide insights into the physiological insults caused by anthropogenic stress, and can ultimately inform conservation and management strategies. Current methods for analysing elasmobranch blood chemistry in the field are often costly and logistically challenging. We compared blood pH values measured using a portable, waterproof pH met...
متن کاملA portable automatic cough analyser in the ambulatory assessment of cough
BACKGROUND Cough is one of the main symptoms of advanced lung disease. However, the efficacy of currently available treatment remains unsatisfactory. Research into the new antitussives requires an objective assessment of cough. METHODS The aim of the study was to test the feasibility of a new automatic portable cough analyser and assess the correlation between subjective and objective evaluat...
متن کاملClinical pilot study assessment of a portable real-time voice analyser.
The use of computer-based real-time visual displays is now well established in voice clinics. A number of situations exist, however, where a computer-based system is inconvenient and a battery-powered hand-held version would be preferred. This would, for example, enable voice monitoring to be carried out at any time and place, including during home visits. This paper describes a purpose-built d...
متن کاملPerformance comparison of 4 portable oxygen concentrators.
BACKGROUND Several portable oxygen concentrators (POCs) have become available in the United States. Technical trade-offs are made in designing POCs, so their performance is expected to differ. METHODS We tested 4 POC models (Invacare XPO(2), Respironics EverGo, AirSep FreeStyle, and Inogen One) for oxygen delivery as a function of respiratory rate. We measured oxygen volume per pulse, pulse d...
