Differences in regional wash-in and wash-out time constants for xenon-CT ventilation studies.
UNLABELLED Xenon-enhanced computed tomography (Xe-CT) has been used to measure regional ventilation by determining the wash-in (WI) and wash-out (WO) rates of stable Xe. We tested the common assumption that WI and WO rates are equal by measuring WO-WI in different anatomic lung regions of six anesthetized, supine sheep scanned using multi-detector-row computed tomography (MDCT). We further inve...
متن کاملWash-in and wash-out of sevoflurane in a test-lung model: A
Modern anaesthesia workstations are reassuringly tight and are Background: equipped with effective gas monitoring, thus providing good opportunities for low/minimal flow anaesthesia. A prerequisite for effective low flow anaesthesia is the possibility to rapidly increase and decrease gas concentrations in the circle system, thereby controlling the depth of anaesthesia. We Methods: studied the w...
متن کاملClosed circuit rebreathing to achieve inert gas wash-in for multiple breath wash-out
Multiple breath wash-out (MBW) testing requires prior wash-in of inert tracer gas. Wash-in efficiency can be enhanced by a rebreathing tracer in a closed circuit. Previous attempts to deploy this did not account for the impact of CO2 accumulation on patients and were unsuccessful. We hypothesised that an effective rebreathe wash-in could be delivered and it would not alter wash-out parameters. ...
متن کاملTo wash or not to wash? That is the question.
books on sport medicine. I am not bragging about this but simply stating an easily verifiable fact. I had recently been reading a newspaper article that noted that the second biggest killer of children in the world is not malaria or tuberculosis, nor AIDS. It is diarrhoea. Over 2000 children die every single day throughout the world from this problem. The simplest solution to reducing this dise...
متن کاملAn inflammatory myofibroblastic tumor in the transplanted liver displaying quick wash-in and wash-out on contrast-enhanced ultrasound
RATIONALE Inflammatory myofibroblastic tumor (IMT) is an uncommon mesenchymal neoplasm, and its presence in a grafted liver is exceedingly rare. PATIENT CONCERNS A 54-year-old woman was admitted to our hospital with a half-month history of intermittent melena. She had undergone deceased-donor liver transplantation (LT) for hepatitis B virus related liver cirrhosis without hepatocellular carci...
