Indication of inputs Ĭentral venous access is most often needed for the introduction of a central venous catheter (CVI). In some cases, the central river can be cannulated even through the peripheral veins on the HK. For Europeans however the data for now is interesting to look at but not yet trustworthy enough when it comes to targeting Europe.Central venous access is access to the basin of the superior or inferior vena cava by cannulation of some major tributary. Now for you US people out there that is not a problem. The problem with the tool is that you a) have to know what data you want to use to make it useful and b) have to work with US data. The tool can really help you get an insight into what people are interested in in what period of time, without having to type in keywords all the time. I accidentally drawed a line which correlated well with “ads by Google”. Here you can draw a curve, hit ‘Correlate!’ and find query terms whose popularity over time matches the shape you drew. They founda similar pattern to actual flu rates:Īnother ‘cool’ feature is “ Search by Drawing“. ![]() In the example Google used, they uploaded official flu activity data from the U.S. They used the feature to upload your own data series, which makes it really useful. The recent marriage in the UK clearly has had its affect.īut a better example might be the one Google gives themselves. It then shows a graph of US Web Search activity for wedding and the correlated words, in the example below it is “wedding guest”. What you can do for example is type in “wedding” and the tool will give you a subset of keywords with the highest correlation. On their blog Google states that the tool is designed for researchers to see what terms best match the current trends in real life. The tool could very well be an interesting tool for SEOs doing keyword research, but is primarily intended for researchers. In other words: it does what Google Trends does, but in reverse. The tool enables you to find queries with a similar pattern to a target data series. It is currently available in beta in Google Labs. Google just launched an interesting new tool: Google Correlate. ![]()
