Introduction Devices' ergonomics are major determinants of task failure, especially in stressful environments.
Such measurements do not call for modifications to the ion optics of the Q Exactive instruments, but do require specially designed sample introduction devices to permit sample/standard comparison and long integration times.
A factorial design was applied to evaluate plasma conditions employing the Mg II 280/Mg I 285 nm intensity ratio in an axially viewed inductively coupled plasma optical emission spectrometer using different sample introduction devices: a concentric or a V-groove nebulizer and a cyclonic or a Sturman-Masters spray chamber.
The sample-introduction device for ICP MS was modified from the default settings as follows: a PFA μflow of 50 μL min−1 was used as a nebulizer, the double-path Scott type spray chamber was cooled to −5 °C, a 1.0 mm dimmer injector torch was used, and additional O2 (0.1 L min−1) gas was mixed with the argon axial gas flow via a T-adaptor.
The issues related to uncontrolled introduction of device technologies and the need for proper surveillance are not specific to orthopaedics.
In this context, stepwise introduction of device related technologies has been proposed, 29 30 and new high accuracy measurement methods for implant performance have been standardised.
31 Registries and registry consortia, such as the International Consortium of Orthopaedic Registries, 32 are important and critical developments but they cannot influence the paths and loopholes associated with introduction of device related technologies on the commercial market.
But the big change from a year ago has been the introduction of devices such as the Jawbone Up Move and Misfit Flash costing £40 with similar capabilities to those costing more than £100.
Introduction Connected devices have become increasingly common, including for healthcare purposes, since some items now allow a continuous measure of the heart rate (HR) and percutaneous oxygen saturation (SpO2).
