Survey of automated noninvasive blood pressure monitors

Automated noninvasive blood pressure (NIBP) monitors, or automated sphygmomanometers, have been increasingly used both inside and outside clinical environments. An extensive survey of such monitors was carried out over the past five years. This survey covers a broad spectrum of monitors including ambulatory monitors, bedside and transport monitors, stress-test monitors, and monitors that are intended for self-measurement. It includes more than 400 models from suppliers in the United States and many other countries. A review of NIBP measurement methods that have been used in automated NIBP monitors is presented in this paper, along with statistical distributions of their use in the surveyed monitors and a list of the suppliers and monitors.
