How using smart bracelet to regul©'ate blood pressure

1.using smart bracelet toneural ‍≠control

the innervation of the heart the he'₹¶γart and limbs muscle,♠€£★ innervation. Domina±☆₽te the heart called plant nerve, such a₽× s the heart of the sympathet™±±→ic nervous sympathetic and parasympathetic nerveλ&✘ of the vagus nerve. Cardiac sym↕₽ pathetic nerve excitement, its peripheral releas≈$ e a vascular active substances called norepinep∞§≥hrine. This kind of material on myocard♦₽ial adrenergic beta receptors on the cell membra €ne, cause heart rate, increase myocardia​βl contraction force, cardiac ★∞∞output to add, vasoconstrictio∏®n, lower blood pressure; Parasympathetic n α☆ervous excitement, its peripheral release a kin♠₹d of active substance called acetylchol‍✘♥ine. This kind of material on myocardial ₹'πm receptors on the cell m&€embrane, cause the heart rate slows, myocardial ®'contraction force is abate, add £&≤∑in cardiac output and vasodilatioβλα<n, blood pressure drops.₩$ Under normal circumstances, symp±±×•athetic and parasympathe‍ tic nerve on the function of theγ• ≠ heart are mutually dependent and mutually uγ <→nify, coordinate with ×"&←each other.

The nervous system for regulating cardiovas↑ ∞ cular event is accomplished through all so¶÷rts of reflection. In car≥  otid sinus and the arch on th¶‌σe outer membrane of the vessel wall, ♥₹•∞have a good feel nerve endings, wh∞¥en the arterial blood press‍♥ure by low gradually reduce, feel periph ≥eral pressure influence excited to add, ✘λ∞♦and the distribution of nerve impulses, the af"±φferent nerve of cardiovascular∏₩'↕ center, to change ca >&αrdiovascular centers of the event,σ §​ that the activities of reducing refl"©φection, through efferent nerve fib☆π•er affect the activity of the heart and blood vesβ≠"sels, and make the heart contrac↓↔tion weakened, vasodilation, peripheral‍↑ resistance drop, drop in blood p≠↔™₩ressure, and insist oεγ ≈n arterial pressure at a certain level. On the ​Ω®☆contrary, when blood pre✘αγ€ssure suddenly drops, the carotid s©∞•inus baroreceptor feeds information "‍★to the blood center, depressor reflex ¥πis abate, cardiac output to adδ× d, vasoconstriction, add the peripheral res♦¶↑istance, lower blood pressure.

3.smart bracelet chemical sensor system

Near the carotid body and the arch t>₩γγhere are chemical receptor¶≠s (receptors), to the oxygen ≥  and carbon dioxide level♦§s in the blood is very $∑→sensitive. Under the ox≈♣σygen to the body shape, chemical se×↑₩nsors was soothing, reflective provoked the breat<✘¶✘h acceleration, peripheral vascular contraction↑✔, blood pressure; But when★♦ blood pressure drops, receptor wasε¶≈ comfort, they can signal, after vasomotor  §center and autonomic nervous sys$ tem, to regulate arterial b→&Ωlood pressure, back to normal.

So feel some fear, but i÷™n fact these can predict in a  $↔dvance and bring a sharp intelligence braΩ≤≈celet can predict, the new intelδ$♣ligent bracelet usually have blood pressure dγ→etection.
PS:When you need to prevent the heart ↓↓Ω&rate and blood pressure heart rate at the sam₩δδe time please give pr÷$iority to the sharp intelli♥∏×gence bracelet..
