Frontiers of Medicine 2013, Volume 7, Issue 1,   Pages 91-101 doi: 10.1007/s11684-013-0239-5

Abstract:

Blood pressure monitoring has come a long way from the initial observations made by Reverend HalesThere are none that deny the importance of monitoring perioperative blood pressure; however, the limitedblood pressure measurements leaves room for improvement.Invasive monitoring is able to detect beat-to-beat blood pressure measurement, but the risks inherent, and especially the creation of those offering non-invasive but continuous blood pressure monitoring
