How to practice CPAP or other PAP devices
For diagnosed OSA, use CPAP nightly for ≥4 hours (target 6–7). Ensure proper mask fit and pressure calibration. Clean equipment weekly. Compliance correlates directly with benefit, partial use gives limited protection. Re-evaluate annually or if symptoms return.
The evidence behind CPAP or other PAP devices
RCTs and long-term studies show CPAP restores oxygen flow, normalizes sleep architecture, and reduces cognitive decline and cardiovascular risk in OSA. Mechanism: prevents intermittent hypoxia and sleep fragmentation that damage attention, memory, and vascular health. Not indicated for those without sleep-disordered breathing.
