Portable power supply options for positive airway pressure devices

Portable power devices.

T here are few pieces of equipment that are common to virtually all healthcare facilities, but portable power devices or power strips (sometimes called portable power taps) are one of them. Whether it is in a hospital, surgery center, doctor's offi ce, or veterinarian's offi ce, power strips are pervasive as the expansion of electrical equipment continues. The eternal problem appears to be eith...

Bench testing of auto-adjusting positive airway pressure devices.

Continuous positive airway pressure devices are routinely used to treat sleep breathing disorders. Automated devices that adjust the therapeutic pressure have recently been proposed. The utility of such devices is still controversial, as rigorous clinical comparisons are difficult to perform as a result of patient and device differences. The current authors studied automated devices in a respir...

Wireless power pad with local power activation for portable devices

Wireless power transfer by magnetic induction offers a simple to use way to recharge mobile devices like e.g. mobile phone, music players or medical sensors. As shown by a previous report and an existing Power Pad demonstrator, wireless inductive power transfer is possible with a good power efficiency and low magnetic radiation only on a surface and with local activation underneath the mobile d...

Comfort and pressure profiles of two auto-adjustable positive airway pressure devices: a technical report.

STUDY OBJECTIVES The purpose of this study was to compare comfort parameters and pressure profiles of the AutoSet (Resmed) and the SOMNOsmart (Weinmann), two auto-adjustable positive airway pressure (APAP) devices. SETTING The sleep disorders center of a university hospital. DESIGN A single-blind randomized trial protocol was applied. A split night procedure allowed each patient to be treat...
