1. CALCULATOR: CPAP use efficacy
While using CPAP ideally, the AHI is reduced to 0, 1, 2, 3, 4, or 5. While not using CPAP, we assume the AHI remains status quo.The average AHI per night can be calculated using this calculator.
2. &. 3. CALCULATOR: Percentage total sleep time, CPAP must be used to reduce the AHI below 5 OR 10
To be cured of OSAS , the mean AHI must be < 5. What is the minimum percentage of TST during which CPAP must be used to reduce the AHI to < 5?
To "cure" OSA , the AHI should be reduced to below 5, but even with CPAP this seems to be an idealistic goal. Nightly percentage use rises as one reduces the target to below 5. Is an AHI below 10 a more feasible target?
4. CALCULATOR: Percentage of total sleep time CPAP must be used to reduce the AHI by a certain percentage.
Examining CPAP from another angle, what is the minimum percentage of TST during which CPAP must be used to reduce the initial AHI by a certain percentage (%reduction)
