Abstract
New-generation devices that enable continuous non-invasive blood-pressure (cNIBP) monitoring as an alternative to invasive arterial blood-pressure monitoring are being developed. These include a volume-clamp method using transmural pressure control, a tonometer based on the principles of tonometry, and photoplethysmographic sensing calculated using either pulse transit time (PTT) or the second derivative signal. However, meta-analyses of cNIBPs indicate that they are not as accurate as intermittent cuff-based sphygmomanometer measurements. While most of the cNIBP devices have been approved by medical device authorities, regulatory bodies are only starting to discuss standards for them. This paper reviews the benefits and limitations of cNIBP devices and current trends in their regulation and approval.
