Telemedicine using free voice over internet protocol (VoIP) technology.

Though dedicated videoteleconference (VTC) systems deliver high quality, low-latency audio and video for telemedical applications, they require expensive hardware and extensive infrastructure. The purpose of this study was to investigate free commercially available Voice over Internet Protocol (VoIP) software as a low cost alternative for telemedicine.

A comparison of videolaryngoscopic technologies.

Difficulty in managing the airway is a major contributor to the morbidity and mortality of the trauma patient. The video laryngoscope, with its camera at the distal tip of the intubation blade, allows the practitioner an improved view of the glottic opening during intubation. The image from this viewer is transmitted to a monitor, allowing the intubating practitioner to "see around the corner" of a patient's airway.
