OBJECTIVE To develop recommendations for positioning the second-generation pacing esophageal stethoscope for transesophageal atrial pacing in patients positioned prone (P), right lateral decubitus (RLD), and left lateral decubitus (LLD). DESIGN Prospective; patients assigned consecutively. SETTING Tertiary and university hospitals. PARTICIPANTS Thirty (10 in each position group) adult pat...

A novel Monte Carlo-based indoor radio-frequency identification (RFID) positioning scheme is proposed for dual-antenna RFID systems with the cooperation of joint rectification. By deploying reference passive tags on ground to establish an tag-based map, self-positioning a moving platform carrying reader two forward-looking antennas can be simply implemented by looking up positions responded at ...

The fast growing popularity of smartphones and tablets enables us to use various intelligent mobile applications. As many of those applications require position information, smart mobile devices provide positioning methods such as Global Positioning System (GPS), WiFi-based positioning system (WPS), or Cell-ID-based positioning service. However, those positioning methods have different characte...

UNLABELLED There is controversy regarding optimal body positioning (i.e., head-up, head-down) in awake nonfasting individuals to minimize the risk for pulmonary aspiration of gastric contents as the result of gastroesophageal reflux (GER). In the present study, we investigated GER and intragastric-esophageal barrier pressure by means of multichannel intraluminal impedance measurement and intrag...

Prone positioning is a conventional method to enhance oxygenation in Acute Respiratory Distress Syndrome (ARDS) patients who need mechanical ventilator . It is proven that oxygenation is significantly more beneficial in prone position compared to the supine position. Furthermore, numerous evidences have confirmed that prone positioning could prevent lung injuries caused by ventilators
