Hypothesis
How tolerable is the Oscar 2 ambulatory blood pressure monitor among research participants?
Conclusion
The Oscar 2 ABPM device is straightforward to use but can interfere with sleep, with common adverse effects including pain, skin irritation, and bruising.
Supporting Evidence
- Nearly 67% reported that the monitor woke them after falling asleep.
- Commonly reported adverse effects included pain (32%), skin irritation (37%), and bruising (7%).
- Those with poor tolerability were more likely to report being in fair/poor health (75% vs 22%).
- Participants categorized as having poor tolerability were more likely to remove the monitor.
Takeaway
The Oscar 2 blood pressure monitor is easy to use, but it can make it hard to sleep and cause some discomfort.
Methodology
Participants wore the Oscar 2 monitor for 24 hours on two occasions and reported their experiences through a questionnaire.
Potential Biases
Participants were voluntary and received monetary incentives, which may affect their responses.
Limitations
The study had a small sample size and findings may not be generalizable outside the research setting.
Participant Demographics
Participants were mostly adults aged 29-64, with a majority being white and slightly more than half female.
