Effect of device-guided breathing exercises on blood pressure in patients with hypertension : a randomized controlled trial . OBJECTIVE Hypertension is a chronic disorder with a high prevalence worldwide . Despite considerable efforts , it is sometimes hard to reach treatment goals for blood pressure ( BP ) with classical treatment options . Reducing breathing frequency has been advocated as a method to reduce BP . METHODS A randomized , single-blind , controlled trial was conducted in 30 non-diabetic patients with hypertension over a period of 9 weeks to evaluate the effect of a device that helps to slow breathing ( Resperate ) on BP and quality of life ( QoL ) . The control group listened to music and used no other therapeutic device . RESULTS There was no significant difference in change in BP between intervention and control ; BP -4.2 mmHg ( 95 % CI -12.4 to 3.9 ) /-2.6 mmHg ( 95 % CI -8.4 to 3.3 ) . This result did not alter in post hoc analyses , when patients not achieving target breathing frequency ( < 10 breaths/min ) or non-compliant patients were excluded . QoL did not change over time . CONCLUSIONS We found no effect of the Resperate on BP or QoL compared with the control group . We conclude that , at this moment , this device has no added value in the treatment of hypertension .
