Key result
Noninvasive blood pressure measurement using auscultatory and oscillometric methods showed a statistically significant positive correlation (P<0.05) with intra-arterial blood pressure.
Why the study?
Intra-arterial cannulation carries risks, and discrepancies between intra-arterial and noninvasive blood pressure measurements can adversely affect therapeutic decisions and patient outcomes.
Do noninvasive blood pressure measurement methods (auscultatory and oscillometric) correlate with intra-arterial blood pressure in hemodynamically unstable patients?
Cross-Sectional (n=50)
No
Do noninvasive blood pressure measurement methods (auscultatory and oscillometric) correlate with intra-arterial blood pressure in hemodynamically unstable patients?
p-value: p=<0.05
Noninvasive blood pressure measurement methods (auscultatory and oscillometric) correlate well with intra-arterial measurements in hemodynamically unstable patients, offering a reliable alternative for monitoring.
No takes yet. Share an insight, caveat, or question.
May support noninvasive BP monitoring in unstable ICU patients; leaves open need for prospective validation before practice change.
Mathew et al. (2022) conducted a cross-sectional in Hemodynamically unstable patients (n=50). Noninvasive blood pressure measurement (auscultatory and oscillometric) vs. Intra-arterial blood pressure measurement was evaluated on Correlation of noninvasive BP measurements with intra-arterial BP (p=<0.05). Noninvasive blood pressure measurement using auscultatory and oscillometric methods showed a statistically significant positive correlation (P<0.05) with intra-arterial blood pressure.
