Why the study?
Do noninvasive blood pressure monitoring devices Spacelabs 90202 and 90207 accurately measure blood pressure compared to intra-arterial recording in resting and ambulatory subjects?
Do noninvasive blood pressure monitoring devices Spacelabs 90202 and 90207 accurately measure blood pressure compared to intra-arterial recording in resting and ambulatory subjects?
Spacelabs 90202 and 90207 devices accurately track directional changes and systolic blood pressure but significantly overestimate diastolic blood pressure compared to intra-arterial measurements.
No takes yet. Share an insight, caveat, or question.
Spacelabs devices may overestimate diastolic BP in practice; cross-sectional data leaves open need for prospective validation against intra-arterial standards.
Groppelli et al. (1992) studied this question.
