Hypothesis
How do different automatic CPAP machines compare in their pressure behavior and recommendations during home titration?
Conclusion
Pressure behavior and recommendations significantly differ between automatic CPAP machines after both one night and one week of home titration.
Supporting Evidence
- The median pressure value was significantly lower with machine GK 420 than with the other devices.
- The maximal pressure obtained over the one-week titration was significantly higher with Remstar Auto than with the two other machines.
- The variance in pressure recommendation significantly differed between the three machines after one night.
Takeaway
Different machines that help people breathe at night can give different pressure settings, which might affect how well they work.
Methodology
Sixteen untreated obstructive sleep apnea patients were randomly allocated to one of three automatic CPAP machines for a one-week home titration trial in a crossover design.
Potential Biases
Potential bias due to the absence of in-lab assessment of positive pressure needs.
Limitations
Patient selection criteria and lack of in-lab evaluation of positive pressure requirements.
Participant Demographics
14 males and 2 females, average age 49 years, average BMI 30.8.
