Iko Valsalva mufambiro inzira inobatsira pakuwedzeredza kuwedzera inzwi reve vagus nerve , uye nekuwedzera kutengesa kunetseka mumutsipa, zvivi, uye nzeve dzomukati. Mufambiro weValsalva ane maitiro akawanda anobatsira mukurapa, uye muupenyu hwezuva nezuva.
Semuenzaniso, mapadiologist anowanzokurudzira Valsalva kufamba kune varwere avo vane zvikamu zvepamusoro- soro tachycardia (SVT) , senzira yekudzivisa arrhythmia kana ichiitika.
Nzira yeValsavla inovewo nzira yakakosha yevamwe vanhu vane scuba, vanhu vane hiccups - nevamwe vazhinji.
Nzira yekuti Valsalva Maneuver Yakaitwa Sei.
Valsalva anofambisa (iyo inonzi zita rinonzi AM Valsalva, uyo akatanga kurondedzera makore 300 akapfuura senzira yekudzinga pus kubva mukati-kative nzeve), inoitwa nekuedza kuwedzera simba rekuvhara mhepo yakavharwa. Izvi zvinogona kuitwa nekuchengeta muromo wako wakavharwa uye kuvhara mhino dzako, uchiedza kubudisa simba. Izvi zvinowedzera kuwedzera kudzvinyirira muzvitema uye nzeve dzomukati. Kuti uwane kuwedzera mumutauriri we vagal, kuedza kumanikidzirwa kubhadhara kunofanira kuchengetwa kwemaminitsi gumi nemashanu.
Chii Chinonzi Valsalva Maneuver Do?
IValsalva inofambisa zvikuru inowedzera zvinetso mukati mezvivi zvinoshandiswa, uye kunyanya mubhokisi. Muchirevo chisinganzwisisiki, kukwidziridzwa kwechifuva chakakwirira kunokurudzira vagus nerve uye kunowedzera vagal tone. Zvisinei, mufambiro weValsalva unobereka zvinyorwa zvakaoma zvezviitiko zvenyama izvo vanachiremba vakashandisa kwemakore akawanda nekuda kwezvinangwa.
Kubva pane maonero ehupenyu, mufambisi wechipiri wechipiri weValsalva ane zvikamu zvina zvakasiyana :
- Muchitsauko chekutanga , kuputika kwevheji yevhavha yakavhara kunowedzera kuvhara mukati mechifuva chechifuva, icho chinobva chinomesa ropa kubva pamapurmonary kupararira kusvika kuruboshwe rwemwoyo. Saka, kwemaminitsi mashomanana kuwanda kweropa kuri kuputika nemwoyo kunowedzera. ( Verenga pamusoro pemakamuri emwoyo nemagetsi. )
- Muchikamu chechipiri , kuwanda kweropa kuri kuputirwa nemwoyo kamwe kunodonha. Iyi inodonha mumoyo wemitambo inowanikwa nekuti nekuda kwekuwedzera kwemafuro mukati mechifuva chechifu kunodzivirira chero ropa ripi neripi kubva kudzokera kuchipfuva kubva kune imwe yose yomuviri, uye naizvozvo kubva kudzokera kumwoyo. Kubhadhara kudonha kwechibereko chemwoyo, mitezo yeropa yemuviri inowedzera, uye kuwedzerwa kweropa kunobuda. Izvi zvakanyanya kudzvinyirira kweropa zvinopfuurira kwenguva yose yekufamba kweValsavla.
- Chikamu chechitatu chinoitika pakarepo padzidziso yekufema. Kushingaira mukati memapfupa kamwe kamwe kunodonha, uye kupararira kwemapurmonary zvakare-kunowedzera uye kunozadza neropa zvakare. Zvisinei, panguva iyizve kuwedzerwa kwebhokisi (iyo inotora kwemaminitsi mashanu kusvika ku10), chibereko chemuviri chinogona kupfuurira mberi.
- Pakupedzisira, muchikamu chechina ropa rinoyerera kusvika pamwoyo nemapapu rinodzokera kune zvakajairika, sezvinoita chibereko chemoyo uye ropa.
Valsalva Maneuver Chii Chakashandiswa?
Vanachiremba vanoona nzira yeValsalva inobatsira pakusiyanisa pakati pemhando dzakasiyana-siyana dzechirwere chemoyo chevhirivular . Kunyanya mwoyo kugunun'una kunoderera munguva yechikamu chechipiri chekufambisa kwaValsalva, sezvo mwoyo haisi kukura ropa rakawanda panguva ino. Asi kugunun'una kunobatanidza mitral valve prolapse uye hypertrophic cardiomyopathy inowanzowedzera munguva yechikamu chechipiri chevashandi veValsalva.
Kutaura zvakawanda zvakanyanya, kushandiswa kukuru kwezvokurapa kwevashandi veValsalva kukurumidza kuwedzera vagal tone (iyo inowanzoitika kunyanya muchikamu 2). Kuwedzera vagal tone kunononoka kuitisa kwemagetsi emagetsi emagetsi kuburikidza neAV node , uye izvi zvishoma nezvishoma zvakaderedza kutengesa zvakakosha pakugumisa mamwe marudzi eSVT (kunyanya, AV-nodal reentrant tachycardia uye atrioventricular reentrant tachycardia ). ( Verenga pamusoro pemhepo yemagetsi yemhepo. )
Izvi zvinoreva kuti vanhu vane zviitiko zvekare zvezvipembenene zveSVT (izvo zviri zviviri zvakasiyana-siyana) vanowanzokwanisa kukurumidze uye nekuvimbika vanomira arrhythmia chero nguva iyo inowanikwa nekushandisa nzira yeValsalva.
Valsalva mufambiro inowanzoshandiswa nevashambadziri vemashuba panguva yemadzinza, kuti vaenzanise mhirizhonga iri pakati pekunze nekunetseka kwepamusoro kwepamvura pasi pemvura.
Mufambiro weValsalva unogona kubatsira vanachiremba kuti vaone kukuvadzwa kumucheto wepervical. Izvi zvinoita kuti pave nekudzvinyirira mukati memaspine - saka kana pane kuvhara kwemitsipa (somuenzaniso, semugumisiro wekuvhiringidzika kwevanoparadzanisa disc), marwadzo anokonzerwa nekukuvadzwa angakwanisa kuwedzera kwenguva pfupi.
Urologist ingashandisa kuraira kweValsavla kuvabatsira kuti vaongorore kushungurudzika kwekunetseka, sezvo kukwidziridzwa kwepamusoro kwemuviri iyi nzira inobereka inogona kukuvadza urinary kuvuza.
Uye vanhu vakawanda vanoona kuti vanogona kubvisa chiitiko che hiccups nokuita basa reValsalva. Zvichida kuti iyi ndiyo inonyanya kushandiswa uye inonyanya kushandisa kushandiswa kweValsalva.
Shoko Rinobva
IvaValsalva nzira yekugadzirisa kuwedzera kudzvinyirira mukati mezvitema uye nenzeve dzepakati, uye zvekuwedzera vagal tone. Iine maitiro anobatsira mumutambo wemishonga, uye muupenyu hwezuva nezuva.
