How using smart bracσ&±elet to regulate bloo♥♥γd pressure

1.using smart bracele ♦γt toneural control

the innervation of th•→φ♣e heart the heart and limbs muscle, inn↔‌≥✘ervation. Dominate the heart called pl♣♥≠♦ant nerve, such as the↕∞δ heart of the sympat& hetic nervous sympathet δ✘ic and parasympatheticφΩ±♠ nerve of the vagus nerΩ<δve. Cardiac sympathetic nerve exci©"✘♥tement, its peripheral φ‍↕ release a vascular active sub§≠stances called norepinephrine. This ε∞÷∞kind of material on myocardial ad<&®≥renergic beta receptors on theα←↔λ cell membrane, caus>♠e heart rate, increase myoc$€ardial contraction force, cardσ iac output to add, vasocon‌×£βstriction, lower bloo‍ €d pressure; Parasympatheti✘✔c nervous excitement, its peripקheral release a kind of active suγ"bstance called acetylc✘£≥holine. This kind of mat>→erial on myocardial m receptors on the ↕€ ©cell membrane, cause the hea≤ ≤πrt rate slows, myocardial contract✘≠£γion force is abate, ★™add in cardiac output aβ <nd vasodilation, blood pressu∞ §re drops. Under normal ¥  ∞circumstances, sympathetic&§ and parasympathetic ne ​₩↕rve on the function of the heart are mu•≈™♥tually dependent and mutually unif↓©→"y, coordinate with ea↑♣♦£ch other.

The nervous system for regul>δ♠£ating cardiovascular event λ€÷is accomplished through all sβ< orts of reflection. ∞®☆In carotid sinus and the >≤arch on the outer membraΩ→₽‌ne of the vessel wall, hav£©£e a good feel nerve endings, when the ✘‌β¶arterial blood pressure b≈¶∏​y low gradually reduce, fe♥✘§el peripheral pressure ™∏& influence excited to add, and the ≤φ₹distribution of nervΩ<e impulses, the afferent nerve o‍>→f cardiovascular center, ε<±to change cardiovascular cente↑∑≤rs of the event, that t₩•×he activities of reducing refλ★β¶lection, through efferent nerve fib$✔er affect the activity of the hear‌∑→t and blood vessels, and make the☆‍ heart contraction weakened, vasodila®®§≠tion, peripheral resistance drop, dro♥♦p in blood pressure, and insist o→♦₩∞n arterial pressure at a certain £€×≈level. On the contrary,§β• when blood pressure♠φ suddenly drops, the carotid sinus baro™‍αreceptor feeds information ↑±φ'to the blood center, depressor refl↑☆ex is abate, cardiac ★&♠output to add, vasoconstriction, add←σ₩∑ the peripheral resistance, lowe±‌φ&r blood pressure.

3.smart bracelet chemi±≠ααcal sensor system

Near the carotid body and the arch t☆≈here are chemical receptors♥σ ↑ (receptors), to the oxygen and carb"&on dioxide levels in★$ the blood is very sensitive. Under tβ★he oxygen to the body sh♦"ape, chemical sensors was soothing♣≈, reflective provoked the breath σ® acceleration, peripheral vascu®×↔∏lar contraction, blood pressure; Butπ÷α♣ when blood pressure≤≥ drops, receptor was co∑÷♠>mfort, they can signal, after vasom$♥✘otor center and autonomic nervous sys<¶♠ tem, to regulate arterial blood pressu‍πΩre, back to normal.

So feel some fear, but in fact¶₩↔‌ these can predict in ♦×♥₽advance and bring a sharp intelligen¥¶≤ce bracelet can predic§ααt, the new intelligent bracelet usuallε$y have blood pressure detection.
PS:When you need to prevent the he→ art rate and blood pressure heart ←<rate at the same time please gi↑®  ve priority to the sharp±δ←$ intelligence bracelet..
