Umfutho wegazi kanye nomfutho wegazi ophakeme
Inhliziyo esebenza njengepampu ipompa igazi, ilinika zonke izitho zomuntu. Njengoba inhliziyo ihlangana, igazi lingena emithanjeni yegazi, libangele ingcindezi ebizwa ngokuthi phezulu, futhi ngesikhathi sokukhula noma ukuphumula kwenhliziyo, kufakwa ingcindezi encane emithanjeni yegazi, ebizwa phansi.
Umfutho wegazi ojwayelekile womuntu onempilo (olinganiselwa ku-mmHg) uthathwa njengophakathi kuka-100/70 no-130/80, lapho idijithi yokuqala ingcindezi ephezulu bese owesibili ingcindezi ephansi.
Indlela emnene yomfutho wegazi ophakeme ibonakala ngokwanda kwengcindezi engenhla kwe-160/1100, isilinganiso esisuka ku-160/11 kuya ku-180/1010, ngefomu elinzima lingakhuphuka ngaphezulu kuka-210/120.
Izinhlobo zokuqapha umfutho wegazi
- Ukulinganiswa kwengcindezi yemanuwali;
- Okokuzenzakalela;
- Ngokuzenzakalelayo.
Kungakhathalekile imodeli, into ephoqelekile yanoma iyiphi i-tonometer iyi-cuff, egqoke engalweni phakathi kwe-elbow nehlombe.
Ikhithi yokulinganisa ingcindezi ifaka i-cuff exhunywe yibhubhu iye isibani, lapho umoya upha khona, imanometer esetshenziselwa ukubonisa ukufundwa kwengcindezi kanye noconendoscope ukulalela ukushaya kwenhliziyo.
Izingqapheli zokucindezela kwegazi ezilinganayo zihlukile kuhlobo lokuqala engxenyeni yokulinganisa - zinesibuko esikrinini lapho kukhonjiswa khona amanani wegazi lengcindezelo legazi elingaphezulu nelingezansi.
Kumadivaysi wokulinganisa ingcindezi othomathikhi kune-cuff kuphela nombukiso, ngaphandle kwe-bulb.
Indlela yokulinganisa
- Ukukala umfutho wegazi nge-tonometer ebhukwayo, kufakwa i-cuff engalweni, bese kufakwa ikhanda lekholoni kusifunda se-ulnar cavity. Ngosizo lwethanga, umoya uphahlwe ku-cuff, ngesikhathi sokukhululwa komoya kubalulekile ukulalelisisa ukushaya kwenhliziyo futhi lapho kuvela ukushaywa okubili noma kokuqala, udinga ukukhumbula inani eliku-dialeter. Lokhu kuzoba yingcindezi ephezulu. Lapho umoya wehla, ukushaya kuzobe kuhluka kakhulu kuze kube yilapho enyamalala, mzuzu lapho ukushaya kuphele futhi kuzokhombisa ukubaluleka kwengcindezi ephansi.
- Indlela yokulinganisa usebenzisa ama-semi-othomathikhi egazi wegazi ahlukile ngoba asikho isidingo sokulalela ukushaya kwenhliziyo, isibonisi sizokhombisa ngokuzenzakalela amanani omfutho ophakeme naphansi ngesikhathi esifanele.
- Lapho ulinganisa umfutho wegazi nge-othomathikhi yokucindezela kwegazi othomathikhi, udinga nje ukubeka i-cuff esandleni sakho bese uvule inkinobho, uhlelo luzodonsa umoya lukhombise amanani wokucindezela.
Ukunquma ngokunembile inani lokucindezela kwegazi, ukukala okukodwa akwanele. Imvamisa ukulinganisa kokuqala kukhombisa umphumela oveziwe wamanga ngenxa yokucindezelwa kwemikhumbi yi-cuff.
Umphumela wokulinganisa ongalungile kungenzeka futhi ube yiphutha lephutha kusisetshenziswa. Kulokhu, kuyadingeka ukwenza ezinye izilinganiso ezingama-2-3, futhi uma ziyefana ngokulandelana, khona-ke isibalo sizosho inani langempela lokucindezela. Uma izinombolo ngemuva kwezilinganiso 2nd ne-3 zihlukile, kufanele kwenziwe ezinye izilinganiso kuze kube yilapho inani elilingana nezilinganiso zangaphambili selisunguliwe.
Cabanga ngetafula
| Icala No. 1 | Icala No. 2 |
| 1. 152/93 | 1. 156/95 |
| 2. 137/83 | 2. 138/88 |
| 3. 135/85 | 3. 134/80 |
| 4. 130/77 | |
| 5. 129/78 |
Esimweni sokuqala, ukucindezela kukalwe izikhathi ezi-3. Ngokuthatha inani eliphakathi kwezilinganiso ezi-3, sithola ingcindezi elingana no-136/8. Esimweni sesibili, lapho kukalwa ingcindezi amahlandla ama-5, amanani wesilinganiso se-4 nelesi-5 alinganayo futhi awadluli ku-130 /77 mm Hg. Isibonelo sikhombisa ngokucacile ukubaluleka kwezilinganiso eziningi, kukhombisa ngokunembile ingcindezi yegazi uqobo.
