Key result
Pulse oximetry SBP estimates show good agreement with Korotokoff sounds and standard noninvasive equipment.
Why the study?
Conventional techniques often fail to monitor systolic arterial blood pressure in patients with Takayasu's syndrome, necessitating evaluation of pulse oximetry as an alternative method.
Does pulse oximetry accurately measure systolic blood pressure compared to conventional methods in healthy volunteers?

Does pulse oximetry accurately measure systolic blood pressure compared to conventional methods in healthy volunteers?
Pulse oximetry can be used as an alternative method to measure systolic arterial blood pressure, which may be particularly useful in patients with pulseless disease such as Takayasu's syndrome.
Chawla et al. (1992) conducted an observational in Healthy volunteers (n=100). Pulse oximetry vs. Korotokoff sounds and noninvasive blood pressure equipment was evaluated on Agreement of systolic blood pressure estimates. Pulse oximetry-based systolic blood pressure estimates showed good agreement with Korotokoff sound pressures and noninvasive equipment pressures.
