Pre-oxygenation: silence the flush

Pre-Oxygenation: A Comparison of Three Techniques

Background: Pre-oxygenation is a time honoured ritual carried out in a variety of circumstances. Various methods of preoxygenation have been proposed and followed world wide with vaviable success. The purpose of this study was to evaluate the need for pre-oxygenation prior to the induction of general anaesthesia and also compare the effects of three techniques of pre-oxygenation, on peripheral ...

The chlorpropamide alcohol flush.

Many non-insulin dependent diabetics (NIDDs) on the sulphonylurea chlorpropamide experience intense facial flushing after taking alcohol even in small amounts. This chlorpropamide alcohol flush (CPAF) was first recognized within months of the introduction of the drug in the 1950s [ l ] but, although an alcohol flush occasionally occurs with tolbutamide [ 2 , 31, it has not been reported with ot...

RFLUSH: Rethink the Flush

A FLUSH command has been used for decades to enforce persistence and ordering of updates in a storage device. The command forces all the data in the volatile buffer of the storage device to non-volatile media to achieve persistency. This lump-sum approach to flushing has two performance consequences. First, it slows down nonvolatile materialization of the writes that actually need to be made du...

Don’t Flush the Yuck Factor

Flush+Flush: A Fast and Stealthy Cache Attack

Research on cache attacks has shown that CPU caches leak significant information. Proposed detection mechanisms assume that all cache attacks cause more cache hits and cache misses than benign applications and use hardware performance counters for detection. In this article, we show that this assumption does not hold by developing a novel attack technique: the Flush+Flush attack. The Flush+Flus...
