A simple method of partial inflation of the LMA cuff before insertion in children to allow cuff pressure without adjustment after insertion

BACKGROUND The cuff of the laryngeal mask airway (LMA) is preferred to be partially inflated before insertion in pediatric cases. However, it is not known how much inflation is appropriate. In addition, intra-cuff pressure is not routinely monitored in many institutions despite the fact that a neglected high cuff pressure could cause several complications. This study was conducted to determine ...

Validation of volume-pressure recording tail-cuff blood pressure measurements.

BACKGROUND The American Heart Association has recommended tail-cuff blood pressure measurement for high-throughput experimental designs, including mutagenesis screens and genetic crosses. However, some tail-cuff methods show good agreement with radiotelemetry and others do not, indicating that each tail-cuff method requires independent validation. METHODS We validated the volume-pressure reco...

Optimum Operating Pressure Ratio for Scroll Compressor

A scroll compressor has a bu~lt-in pressure ra~~o related to geometry of scroll wraps and efflciency of the compressor depends on the relation between the ratio and an operat~ng pressure rat~o. Th~s paper analyses theoretl.cal performance of the compressor by tak1ng account of flow resistances at opem.ngs of scroll wraps and leakage flows through wrap clearances. The flow resl.stance at the d1s...
