Key result
Novel cuffless pneumatic tonometric sensor accurately monitors blood pressure waveforms compared to direct measurement.
Why the study?
Existing non-invasive arterial blood pressure measurement devices typically require a cuff and have limitations in measuring arterial pressure waveforms at certain sites such as the carotid artery.
Comparison

May enable cuffless waveform monitoring; leaves open prospective validation before clinical adoption.
A novel cuffless pneumatic tonometric sensor provides accurate arterial pressure waveform measurements comparable to direct methods, potentially allowing monitoring at sites like the carotid artery.
Tomczuk et al. (2013) studied Blood pressure monitoring. Cuffless pneumatic tonometric sensor was evaluated on Sensor characteristics and dynamic properties. A novel cuffless pneumatic tonometric sensor demonstrated linear steady-state characteristics and satisfactory dynamic properties for accurate blood pressure waveform monitoring.
