Uxinzelelo lwegazi oluphantsi: Izizathu kunye noTyango

Yintoni ephantsi kwegazi? Uxinzelelo lwe-arterium ngumandla apho igazi elijikelezayo lisebenza kwiindonga zemithambo yegazi. Ichazwe njenge-systolic / diastolic, umzekelo, 120/80. Ixabiso eliphezulu liyi-systolic blood pressure, okuyixinzelelo kwimibhobho, xa imisipha yentliziyo ivumelwano kunye nokupompa igazi. Ixabiso eliphantsi li-diastolic, okuyiyo ingcinezelo kwimibhobho, emva kokuqhekeka kweentliziyo zentliziyo. Inani eliphezulu lihlala liphezulu.

Umxinzelelo wegazi lwe-Systolic kubantu abaninzi abadala abanempilo iphakathi kwe-millimitha ye-mercury ikholomu, kwaye i-diastolic yengcinezelo yegazi ivela kwi-60 ukuya kwi-80 mm Hg.

Uxinzelelo lwegazi oluphantsi (okanye i-hypotension) lubangela ukuba igazi alikwazi ukuhambisa izondlo ezaneleyo kunye ne-oksijini kwizitho zomntu ezifana nobuchopho, izintso, intliziyo, njl njl. Ngenxa yoko, azisebenzi ngokuqhelekileyo.

Ngokungafani noxinzelelo oluphezulu, oluphantsi lwegazi lugqityiweyo, okokuqala, ngempawu kunye neempawu, kwaye kungengomfanekiso othile. Abanye abantu banokuba noxinzelelo lwe-90/50 ngaphandle kwempawu, ngelixa abanye bangaphuhlisa iimpawu kwi-100/60.

Uxinzelelo lwegazi oluphantsi kubantu abanempilo ngaphandle kwempawu okanye ukulimala kwizitho zangaphakathi unyango aludingi. Kodwa iingxaki zempilo zenzeka xa ziwa ngokukhawuleza, kwaye ingqondo ilahlekelwa yaneleyo yegazi. Oku kunokukhokelela kwisidlova. Ukuwa ngokukhawuleza kudla ngokuqhelekileyo kumntu okhupha kwisithuba esityebileyo okanye evuka ngokukhawuleza. Ukulahla okunjalo kumanani kubizwa ngeposi, okanye i- orthostatic, hypotension. Ukuba iyancitshiswa kwimeko xa umntu emela ixesha elide, ke lo ngumxholongwane we-neuro-mediated.

Umngcipheko wokwanda kwesi sifo ukwanda ngeminyaka, inxenye ngenxa yeenguqu eziqhelekileyo kwinkqubo yokuguga. Ukongezelela, ukuhamba kwegazi kwingqondo kunye nasentliziyweni yentsiko yehla ngenxa yobudala ngenxa yemigodi yegazi. Kuqikelelwa ukuba ukususela kwi-15% ukuya ku-25% yabantu abadala baye baxhomekeke kwi-postural hypotension.

Ukongeza, zombini uxinzelelo oluphantsi lwegazi kunye nokunyuswa kwengcinezelo yegazi kunokubangelwa zilandelayo:

• Arrhythmia;
• iingxaki ze-hormonal, ezifana ne-hypothyroidism, isifo sikashukela okanye i-hypoglycaemia;
• amanye amayeza;
• ukuhluleka kwentliziyo;
• Ukukhulelwa;
• ukwandiswa kwemithambo yegazi;
• isifo sesibindi;
• Ukutshitshiswa.

Ukukhawuleza ngokukhawuleza nokunyuka kwexinzelelo lwegazi kubungozi bokuphila. Izizathu zolu hlobo lwe-hypotension ziquka:

• ukulahlekelwa kwegazi ngenxa yokuphuma kwegazi;
• ubushushu bomzimba obuphantsi okanye obuphezulu;
• i-sepsis, izifo ezinzulu;
• ukukhulelwa kwamanzi ngenxa yokuhlanza, umkhuhlane, okanye urhudo;
• ukusabela kotywala okanye iziyobisi;
• Ukuxhatshazwa kwamanzi kunye nokutshatyalaliswa kwe-anaphylactic.

Ukuba unesixinzelelo esiphantsi segazi, unyango luya kuba nezikhokelo ezilandelayo:

1. Ukutya:

- Ukwandisa inani leetyuwa ekudleni. Nangona le ndlela ingaba luncedo kwizigulane ezinexholongwane, isongezelelo kufuneka sisetyenziswe ngokulinganisela nangengqiqo yonyango. Uninzi lolutyuwa ekudleni kunokukhokelela kwiingxaki zentliziyo.

- Ukwandisa inani lamanzi linokukunceda ekwenzeni unyango, ngakumbi ukuba isizathu sihambelana nokuphelelwa ngumdaka.

- Ukutya okuphezulu kwi-carbohydrates kunokunceda ukwandisa uxinzelelo lwegazi. Ukongezelela, thintela ukuba ungawa, ungadla amaxesha amaninzi ngosuku, kwiincinci ezincinci, ukutya okuziinkozo, iiprotheni, izithelo kunye nemifuno.

2. Ugcini

Zifumaneka ngaphandle kwemigqaliselo kwii-pharmacy, zinokugqithwa njengekhambi lekhaya lokunyanga uxinzelelo lwegazi oluphantsi. Akunako kuphela ukunciphisa intlungu kunye nokuvuvukala emilenzeni, kodwa kwakhona akayi kuvumela igazi ukuba lihluthe kwizitho.

3. Ukutshintsha isikhundla somzimba:

- Ukunyuka ngokukhawuleza kwiindawo eziqhelekileyo kunokudala ngokukhawuleza kwehla kwingcinezelo. Ukuthintela oku, thatha ixesha lakho, hlala phantsi ngaphambi kokuvuka.
