Fully automatic portable recording of indirect blood pressures in subjects awake and asleep, at home and at work.

The only commercially available automatic indirect blood pressure device in the USA, the Remler 2000, lacks a second channel for recording patients' comments and is not suitable for application during certain activities such as driving a car, or during sleep. A device is presented, circumventing these problems, allowing the recording of blood pressure every 15 min over 10 h. The validation of the device has been proved by comparing 121 determinations with the standard method, and 45 determinations in 9 subjects with intravascular values.
