Effects of Deep Breath on Blood Pressure in Normo-Prehypertension Subjects

Background: Blood pressure (BP) levels variety throughout the day, both by internal stimuli and the influence of external factors. The BP which measured at the clinic are higher than self measurement at home. Deep breathing (DB) is a technique which deep breaths the application paced simulation breath on smarthphone android) continued measurement at 1 minute, 3rd and 5th after DB. Results: 56 male and 63 female, where 66 subjects found normotensive and 53 subjects prehypertensive. The largest decrease in SBP after Deep Breath Test (DBT) at 1st minute (6.61+3.9 mmHg) followed by 3rd and 5th (5.56+4.7 and 3.38+5.3 mmHg), while DBP at 1st minute (3,33+4,34 mmHg) followed by 3rd and 5th (2,34+4,14 and 1,11+4,71 mmHg). The comparison between the reduction of SBP and DBP before DB and after DB was statistically significant at 1st and 3rd minute (0.9+3.1vs 6.6+3.9mmHg), (1.5+3.6vs5.6+4.8mmHg) and DBP in 1st and 3rd minute (0.8+4.3vs3.3+4.3mmHg), (1.3+4.9vs2.3 +4.1mmHg) (P
