Development and clinical validation of a non-invasive, beat-to-beat blood pressure monitoring device, compared to invasive blood pressure monitoring during coronary angiography

Non-invasive beat to beat arterial blood pressure during non-REM sleep in obstructive sleep apnoea and snoring.

BACKGROUND Obstructive sleep apnoea, and possibly snoring, are associated with a poorly understood increase in cardiovascular mortality which may be explained by their effects on systemic blood pressure during sleep. This study compares changes in mean blood pressure during obstructive sleep apnoea and snoring without apnoeas with those in matched control subjects during non-REM sleep. METHOD...

Head-up-tilt testing in children: new perspectives using beat-to-beat blood-pressure monitoring

The head-up-tilt-test in pediatric patients for the evaluation of syncope shows a sensitivity of 35-85% and often requires pharmacological stimulation in order to improve its diagnostic value. We used a new device for beat-to-beat blood pressure monitoring combined with impedance cardiography in a 12-year-old girl during tilt testing. A seven seconds asystolia was provoked. The haemodynamic par...

Techniques for Non-Invasive Monitoring of Arterial Blood Pressure

Since both, hypotension and hypertension, can potentially impair the function of vital organs such as heart, brain, or kidneys, monitoring of arterial blood pressure (BP) is a mainstay of hemodynamic monitoring in acutely or critically ill patients. Arterial BP can either be obtained invasively via an arterial catheter or non-invasively. Non-invasive BP measurement provides either intermittent ...

Non Invasive Blood Pressure

Alongside heart rate, Blood Pressure is one of the physiological parameters which has been measured by clinicians for the longest period of time: it was known to be important in the 16 century. It remains one of the most important physiological indicators to date and is also one of the more awkward parameters to measure. As has been discussed, blood is pumped round the body by the heart. The bl...
