24-Hour blood pressure monitoring
Key result
Non-invasive 24-hour blood pressure monitoring using the Spacelabs 5300 device yielded similar group means to intra-arterial recording but showed large discrepancies in individual subjects.
Why the study?
Does 24-h ambulatory monitoring via the Spacelabs 5300 device accurately estimate blood pressure compared to intra-arterial recording in essential hypertensive subjects?
Population

Implication
Large individual discrepancies caution against Spacelabs 5300 for patient-level ABPM decisions; leaves open validation needs in larger cohorts.

Type
Observational (n=8)
Structured PICO
Does 24-h ambulatory monitoring via the Spacelabs 5300 device accurately estimate blood pressure compared to intra-arterial recording in essential hypertensive subjects?
P
Population
8 essential hypertensive subjects undergoing simultaneous 24-hour non-invasive and intra-arterial blood pressure monitoring.
E
Exposure
24-h ambulatory blood pressure monitoring via the Spacelabs 5300 device (measured every 15 min during the day and 30 min during the night)
C
Comparator
Simultaneous 24-h intra-arterial blood pressure recording from the contralateral arm
O
Outcome
Accuracy of 24-h blood pressure values (hourly and 24-h means for systolic and diastolic blood pressure)surrogate
Main Result
Absolute Event Rate: 138.4% vs 142.9%
The Spacelabs 5300 device has limited ability to correctly estimate ambulatory blood pressure in individual subjects due to large discrepancies compared to intra-arterial measurements, though group means are similar.
Limitations
- The Spacelabs 5300 device has a limited ability to correctly estimate ambulatory blood pressure in individual subjects.

Casadei et al. (1988) conducted an observational in Essential hypertension (n=8). Ambulatory monitoring via Spacelabs 5300 device vs. Simultaneous 24-h intra-arterial blood pressure recording was evaluated on 24-h systolic blood pressure mean. Non-invasive 24-hour blood pressure monitoring using the Spacelabs 5300 device yielded similar group means to intra-arterial recording but showed large discrepancies in individual subjects.
