Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
In the print edition of this summary, a picture is provided of a pregnant woman using a wrist blood pressure monitor, held at the level of the umbilicus, to measure blood pressure. The full guideline makes no mention of BP measurement technique, but measurements taken as illustrated are highly likely to be dangerously misleading.
