a BP measurement procedure. Participants were given 5 min before the initial BP was measured. During deep breathing, before the automated BP measurements started, 3 respiratory cycles were performed, and this continued until the completion of BP measurement. b Illustration of deep breathing with four different respiratory patterns. Pattern 1: slow breathing (↑4.5 s ↓4.5 s); Pattern 2: long inspiration followed by short expiration (↑6 s ↓2 s); Pattern 3: short inspiration followed by long expiration (↑2 s ↓ 6 s); Pattern 4: fast breathing (↑1.5 s ↓1.5 s)
