  • a Tight alarm settings are defined in “Methods.”

  • b Data are median (25th, 75th percentiles) for all patients at each center. Includes monitoring periods with Spo2 from all 4 weeks.

  • c Overall percentage for all patients at each center (range of percentages for individual patients at each center). Includes monitoring periods with modifiable Spo2 from all 4 weeks.
