Validity of phonoarteriographic blood pressures during rest and exercise
Key result
The phonoarteriogram showed good agreement with auscultation across 340 resting and 218 exercise blood pressure determinations in 60 subjects, proving to be a valid and objective method.
Why the study?
Does the phonoarteriogram provide valid blood pressure measurements compared to auscultation and intra-arterial methods during rest and exercise?
Population
60 subjects for resting and exercise determinations, and 2 subjects for intra-arterial determinations

Implication
Supports objective BP recording during exercise; leaves open larger intra-arterial validation before clinical adoption.

Structured PICO
Does the phonoarteriogram provide valid blood pressure measurements compared to auscultation and intra-arterial methods during rest and exercise?
P
Population
60 subjects undergoing resting and exercise blood pressure determinations to validate the phonoarteriogram method.
E
Exposure
Phonoarteriogram (modified amplifying stethoscope recording cuff pressure from a transducer and systolic/diastolic criteria from a microphone)
C
Comparator
Auscultation and intra-arterial blood pressure measurements
O
Outcome
Validity and agreement of blood pressure measurements during rest and exercisesurrogate
The phonoarteriogram is a valid and reliable method for objective blood pressure recording, particularly advantageous during exercise and high ambient noise conditions.

Mastropaolo et al. (1964) reported an observational. Phonoarteriogram vs. Auscultation was evaluated on Agreement between phonoarteriogram and auscultation. The phonoarteriogram showed good agreement with auscultation across 340 resting and 218 exercise blood pressure determinations in 60 subjects, proving to be a valid and objective method.
