Sleep apnea machine may also treat blood disorder
NCT ID NCT06089603
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study tests whether using a CPAP machine at night can reduce high red blood cell counts (polycythemia) in people with moderate to severe sleep apnea. Researchers will compare 182 adults who use CPAP plus standard care to those who receive only standard care over 12 months. The main goal is to see if CPAP lowers hematocrit levels, which could reduce the risk of blood clots and other complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Continuous positive airway pressure (CPAP) device
What this could lead to
If successful, CPAP could become a standard treatment to reduce high red blood cell counts in people with sleep apnea, potentially lowering their risk of blood clots and other complications.
What could go wrong
This is a Phase 4 trial, so CPAP is already approved for sleep apnea, but its effect on polycythemia is not yet proven. The study is not blinded, which could introduce bias, and results may not apply to all patients.
