Capnometry is a method to measure carbon dioxide (CO2) in exhaled gas and it has been used in patients to monitor their respiratory status. Monitoring of exhaled CO2 during endoscopic procedures has been shown to be effective in detecting drug-induced respiratory depression. Oxygen (O2) supplementation is given to patients to abolish hypoxia during endoscopy. However, oxygen administration can interfere...
The importance of capnometry and end-tidal carbon dioxide (ETCO2) has been underscored in recent years by guidelines as a method to continuously monitor adequacy of ventilation during sedation and anesthesia. Guidelines for cardiopulmonary resuscitation (CPR) recommend attempts to improve CPR quality if ETCO2 is lower than 10 mmHg. ETCO2 is thus a time-critical parameter that may benefit from being...
Capnometry is a method to measure carbon dioxide (CO2) in exhaled gas and its use during polysomnography (PSG) for diagnostic of sleep apnea-hypopnea syndrome is expanding. However, some problems exist for using capnometer in combination with other respiratory monitoring devices because capnometry requires additional sampling cannula or airway adapter attached to patients. To resolve these problems,...
We are studying an interactive panoramic video streaming system that enables consumers using consumer network resources and HDTVs that most consumers have in their homes to watch high-resolution panoramic images beyond HD quality. We propose a new data format and a partial delivery method with multiple bitrates and resolutions. This paper describes a field trial conducted to evaluate the system on...
Capnometer has been widely used as a respiratory monitor. Stable carbon dioxide (CO2) monitoring of non-intubated patient is especially problematic due to the frequent occurrence of tube obstruction and it could be even more difficult when oxygen is being administered. Oxygen is often administered by an oxygen mask or oxygen nasal cannula; however there are some problems with these methods. For oxygen...
When we appreciate sports or music event at the stadium or the concert hall, we can feel atmosphere of the event site and get impressed by the live performance. We have studied visual and sound delivery system to convey the reality as if you enjoyed the event from the premium seat. We propose the interactive panorama video system which consists of panorama video synthesis, panorama video coding and...
Multiprotocol Label Switching (MPLS) Point to Multipoint (P2MP) can be used as an underlying technology for transmitting video data. Reducing the transmission delay on a network is very important to maintain the quality of service for video transmission. Therefore, the hop count of the path between a source and a destination node should be reduced using MPLS P2MP routing technology. We considered...
We focus on a method of computing recovery path routes in a mesh IP network, which is expected to be used when unforeseen massive failure or disaster occurs. We introduce the concept of “path-group” to differentiate recovered paths according to their priority. We assign a priority to a path-group in the concept. The routes for path-groups are computed for recovery in the order of their priority. The...
