The American Heart Association considers device-guided breathing as a reasonable treatment modality in their statement on non-pharmacological options for lowering blood pressure. This review discusses all randomized controlled trials that have investigated the effects of device-guided breathing on blood pressure in patients with hypertension. Thirteen studies were included in this review. In total, 627 patients were included, of which 365 patients were allocated to device-guided breathing. Only 6 studies used acceptable control groups: listening to music, meditative relaxation exercises, or a sham-device. Two sponsored trials showed beneficial effects of device-guided breathing, both used listening to music as a control group. The remaining 4 studies, which had no employees of the manufacturer listed as co-author, observed no beneficial effects on blood pressure. There is only 1 study that used a sham device as a control group. All other studies were to some extend methodologically flawed. Based on the studies with an acceptable methodological quality, there is no clear evidence supporting a short-term beneficial effect on blood pressure by using device-guided breathing.
美国心脏协会在其关于降低血压的非药物选择声明中，将设备引导呼吸视为一种合理的治疗方式。本综述讨论了所有调查设备引导呼吸对高血压患者血压影响的随机对照试验。本综述纳入了13项研究。总共纳入了627名患者，其中365名患者被分配到设备引导呼吸组。只有6项研究使用了可接受的对照组：听音乐、冥想放松练习或假设备。两项赞助试验显示了设备引导呼吸的有益效果，两者均使用听音乐作为对照组。其余4项研究（未将制造商的员工列为共同作者）未观察到对血压的有益效果。只有1项研究使用假设备作为对照组。所有其他研究在方法上都存在一定缺陷。基于方法学质量可接受的研究，没有明确证据支持使用设备引导呼吸对血压有短期有益效果。
