Hypothesis
Can pulse wave velocity provide a reliable estimate of cardiac output during elective surgery?
Conclusion
Pulse wave velocity is not an accurate estimate of cardiac output as measured by the gold standard method.
Supporting Evidence
- Pulse wave velocity was measured on 287 occasions.
- Stroke volume was calculated using both pulse wave velocity and a gold standard method.
Takeaway
The study looked at how fast blood moves through arteries and whether it can help measure heart output during surgery, but it found that it doesn't work well.
Methodology
Adult patients undergoing major elective surgery were monitored for pulse wave velocity and stroke volume using specific medical devices.
Limitations
The study had a small sample size and potential unreliability in pulse wave velocity recordings.
Participant Demographics
Patients aged 45 to 74 years, with five men and six women.
