Uluphi uvavanyo lweValsalva kunye nendlela yokuyenza?

Uluphi uvavanyo lweValsalva? Inkqubo eyenziwa ngumfutho wenziwa ngamabomu. Umlomo kunye neengcambu zengca zivaliwe ukwenzela ukuba uxinzelelo olufunekayo lwesisu esiswini kunye nesigxina se-thoracic senzeke. Le ndlela ibizwa ngokuba ngu-anatomist odumile wase-Italy. Kodwa ngenjongo yintoni le nkqubo, eyaziwa namhlanje njengetyala leValsalva, likhonza?

Ukusebenzisa le ndlela, kunokwenzeka ukugxotha ngokufanelekileyo, umzekelo, ukusuka kwintendelezo yeendlebe kunye neenkqubo eziqhelekileyo kubantu abaninzi namhlanje. Ngokuqinisekileyo inkqubo enjalo isoloko ibiza igama loxinzelelo ku-Вальсальве.

Ngokuqhelekileyo le nqubo iyenziwa, umzekelo, abaxhamli xa behlayela ekujuleni, kunye nabagibeli beenqwelo-moya ngexesha lokukhutshwa kunye nokufika. Oku kunceda ukulungelelanisa uxinzelelo kwimihlathi yomibini kunye nasendlebeni yomphakathi.

Ngendlela eyiyo ukuqhuba inkqubo enjalo? U vavanyo lweValsalva luququzelele ekwenzeni ukuphefumula okupheleleyo kunye nokuphefumula. Emva koko isigulane kufuneka senze enye i-exhalation eqinile kwaye ibambe ngamandla. Kulo lonke ixesha, ukurekhodwa ngokucacileyo kwe-electrocardiogram kwenziwa, kwakunye nokurekhoda okufunekayo kwe-diastolic, ukunyanzezela kwegazi.

Kukho ukhetho oluninzi lwale vavanyo. Kwesinye isigulane esinokuthi silele emhlane wakhe. Kwimizuzu engama-15, umntu kufuneka aqhube kwi-tube ekhethekileyo exhunywe kumanometer, okwenza uxinzelelo olufunekayo kwinkqubo (malunga ne-40 mm Hg).

Ityala leValsalva libandakanya amanyathelo amanqanaba asemgangathweni. Ubudala, indawo yomzimba kwisithuba, ngesondo, uxinzelelo oludalwa ngumoya ojulileyo, kunye nokusetyenziswa rhoqo kwamachiza athile kunokuchaphazela umphumo wesifundo.

Ngokuqhelekileyo abantu abanesabelo esizuze ilifa kwizifo ezixhamlayo zinezifo ezinesifo. Ngokuqhelekileyo kunokwenzeka ukuqaphela i-coronary side side yesinus echaphazelekayo yeValsalva. Isiqhelo sisoloko senziwa kubantu abatsha okanye nakubantwana.

Ukuba wenza okufanayo (kuchazwe ngasentla), indlela yokugcina umoya eyenzeka kwimiphunga idala uxinzelelo oluninzi. Kwaye uxinzelelo olunzulu kwisifuba nesisu esiswini sehlisa ukubuyiswa kwegazi elifanelekileyo eliyingozi kwiintliziyo. Oku, kunokubangela ukuba inani legazi elikhishwe yintliziyo kwiinqanawa, liyancitshiswa. Kuzo zonke ezi ngasentla, sinokugqiba ukuba abantu abanesifo sengqondo senhliziyo, le nkqubo ayinqatshelwe, ngokukodwa ngaphandle kokulawulwa ngugqirha.

Unako ukuqokelela encinane. Njengoko kunokubonakala, iilingo zeValsalva zisetyenziselwa injongo ethile, oku: ukuvavanya amathuba okufa ngokukhawuleza xa kwenzeka isigwebo, ngokuqhuba uvavanyo oluthile. Kule meko, izinga lentliziyo lilinganiswa , ukuhluka kwesigqi kuyaqikelelwa. Ukuba isiphumo siphantsi, umngcipheko wokufa ngokukhawuleza uphezulu kakhulu.
