Does pursed lip breathing lower heart rate?
When the two groups were compared, a greater degree of reduction was found in the intervention group for SBP (9.80 mm Hg, 95%CI; 4.10 to 15.50), DBP (7.69 mm Hg, 95%CI; 3.61 to 11.77), and HR (3.85 bpm, 95%CI; 1.99 to 5.72). In conclusion, PLB with NC was effective for lowering BP and HR.
