Evaluating early ventilation effects on stroke recovery in patients with sleep apnea

A Single-center, Randomized, Open Label, Parallel Arm, Prospective Study to Evaluate the Impact of Early Ventilation in Stroke Outcomes in Patients With Sleep Apnea After First Ever Stroke

Phase 2 Interventional Philips Portuguesa S.A. · NCT04903951

This study is testing if using a special breathing machine early on can help people with sleep apnea recover better after their first stroke.

What this trial studies

This study aims to assess the impact of early ventilation using Adaptive Servoventilation (ASV) on the recovery outcomes of patients who have experienced their first-ever ischemic stroke and have sleep apnea. It is a single-center, randomized, open-label trial where participants will be assigned to either receive ASV therapy or standard medical treatment for stroke. The intervention will begin within four days of stroke onset and will continue until clinically indicated, with follow-up assessments conducted one month post-stroke. The study will involve screening, baseline assessments, and follow-up visits to evaluate the effectiveness of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 who have experienced their first ischemic stroke and have a diagnosis of sleep apnea.

Not a fit: Patients with conditions such as advanced chronic lung disease or those requiring prior ventilation treatment for sleep apnea may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery outcomes for stroke patients with sleep apnea.

How similar studies have performed: While this approach is innovative, similar studies have shown promising results in improving outcomes for patients with sleep apnea and other conditions.
