By applying an external modulation of pressure alongside conventional blood oxygen saturation the reliance on the natural heartbeat can be bypassed entirely.
Features
Benefits
Applying pressure modulation
So that the induced change in pressure can be used to make the measurement, not relying on the natural heartbeat period.
Rapid measurement
No longer the necessity to wait for 10s of seconds, allowing time for movement to disrupt the measurement
Measurement is reliant on known frequency pressure modulation, not natural heartbeat
This means the modulation is more predictable and the measurement can be more accurate
Ability to identify the arterial waveform
So that measurements associated specifically with arterial blood can be extracted
