Overview

Supports PDA for noninvasive BP in catheterization labs; leaves open prospective validation before clinical adoption.

Structured PICO

Does the CareTaker system with PDA algorithm accurately measure continuous noninvasive blood pressure compared to invasive central line catheters in patients undergoing cardiac catheterization?

P
Population
63 patients (38 male, 25 female, mean age 62.7 years) undergoing cardiac catheterization
I
Intervention
Continuous noninvasive blood pressure monitoring using the CareTaker system and Pulse Decomposition Analysis (PDA) algorithm
C
Comparator
Invasive central arterial blood pressure monitoring using central line catheters
O
Outcome
Correlation of PDA parameters (P2P1 and T13) with systolic and pulse pressures, and Bland-Altman agreement with invasive central arterial blood pressuresurrogate

The CareTaker system with PDA algorithm provides accurate continuous noninvasive blood pressure measurements that correlate strongly with invasive central line catheter measurements.
