Continuous ambulatory pulmonary artery pressure monitoring. A new method using a transducer tipped catheter and a simple recording system.
Why the study?
Does a transducer tipped catheter and simple recording system accurately measure continuous ambulatory pulmonary artery pressure compared to a conventional fluid-filled system in patients undergoing investigation for coronary artery disease?
Population
13 patients undergoing routine investigation for coronary artery disease
Comparison
Continuous ambulatory pulmonary artery pressure… vs Conventional fluid-filled system (in 8 patients)
Design
Case_series
Follow-up
288 hours total monitoring

Implication
Hypothesis-generating for transducer-tipped ambulatory pulmonary artery pressure monitoring; leaves open larger prospective validation before clinical use.
Structured PICO

P
Population
13 patients undergoing routine investigation for coronary artery disease
I
Intervention
Continuous ambulatory pulmonary artery pressure monitoring using a transducer tipped catheter and a miniaturised tape recorder
C
Comparator
Conventional fluid-filled system (in 8 patients)
O
Outcome
System accuracy, zero drift, linearity error, and correlation with conventional fluid-filled systemsurrogate
A transducer tipped catheter with a simple recording system is a feasible and accurate method for continuous ambulatory pulmonary artery pressure monitoring.
