Using positive airway pressure to manage blood pressure issues in older adults

Official title: Hemodynamic Effects of Positive Airway Pressure to Treat Supine Hypertension and Improve Neurogenic Orthostatic Hypotension

Funded at Vanderbilt University Medical Center · NIH-10986079 · Data updated 2026-11-12

This study is looking at how using a CPAP machine, which helps with breathing during sleep, might lower high blood pressure that some older adults experience when lying down, and it hopes to make them feel better when they stand up during the day.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults experiencing supine hypertension and orthostatic hypotension, particularly those with impaired autonomic reflexes.

Less likely to help

Patients who do not have issues with blood pressure regulation or those without supine hypertension may not benefit from this research.

What this research studies

This research investigates how continuous positive airway pressure (CPAP) can help treat supine hypertension, a condition where blood pressure rises while lying down, which is common in older adults. The study aims to understand how CPAP can improve blood flow and reduce symptoms of orthostatic hypotension, where blood pressure drops upon standing. By applying CPAP, the researchers hope to create a similar effect to sleeping in a head-up position, potentially alleviating nighttime hypertension and its daytime consequences. Patients will be monitored to assess changes in blood pressure and related symptoms during the treatment.

Why it matters

Potential benefit: If successful, this research could provide a new, effective treatment option for managing blood pressure issues in older adults, improving their quality of life.

How similar studies have gone: Preliminary studies have shown promising results using CPAP for similar hemodynamic effects, indicating potential for success in this approach.
