Uxinzelelo lwegazi luphawu olubalulekileyo lweempawu ezibalulekileyo zomzimba womntu. Umgangatho woxinzelelo lwegazi unokunceda ekumiseleni ukuba ukusebenza kwentliziyo yomzimba womntu, ukuhamba kwegazi, umthamo wegazi, kunye nomsebenzi we-vasomotor ngokuqhelekileyo zihambelana. Ukuba kukho ukunyuka okanye ukwehla okungaqhelekanga koxinzelelo lwegazi, oko kubonisa ukuba kunokubakho ukungaqheleki kwezi zinto.

Ukulinganisa uxinzelelo lwegazi yindlela ebalulekileyo yokujonga iimpawu ezibalulekileyo zezigulane. Ukulinganisa uxinzelelo lwegazi kunokwahlulwahlulwa kube ziintlobo ezimbini: ukulinganisa i-IBP kunye nokulinganisa i-NIBP.

I-IBP ibhekisa ekufakweni kwe-catheter ehambelanayo emzimbeni, ehamba nokugqobhozwa kwemithambo yegazi. Le ndlela yokulinganisa uxinzelelo lwegazi ichanekile ngakumbi kunokujonga i-NIBP, kodwa kukho umngcipheko othile. Ukulinganisa i-IBP akusebenzi kwizilwanyana zaselabhoratri kuphela. Akusasetyenziswa rhoqo.

Ukulinganisa i-NIBP yindlela engangqalanga yokulinganisa uxinzelelo lwegazi lomntu. Ingalinganiswa kumphezulu womzimba nge-sphygmomanometer. Le ndlela kulula ukuyijonga. Okwangoku, ukulinganisa i-NIBP yeyona isetyenziswa kakhulu kwimarike. Ukulinganisa uxinzelelo lwegazi kunokubonakalisa ngokufanelekileyo iimpawu ezibalulekileyo zomntu. Ke ngoko, ukulinganisa uxinzelelo lwegazi kufuneka kuchaneke. Enyanisweni, abantu abaninzi basebenzisa iindlela zokulinganisa ezingalunganga, ezihlala zikhokelela kwiimpazamo phakathi kwedatha elinganisiweyo kunye noxinzelelo lwegazi lokwenyani, nto leyo ekhokelela kwidatha engachanekanga. Oku kulandelayo kuchanekile. Indlela yokulinganisa yeyokubhekisela kuwe.

Indlela echanekileyo yokulinganisa i-NIBP:

1. Ukutshaya, ukusela, ikofu, ukutya kunye nokuzilolonga akuvumelekanga kwimizuzu engama-30 ngaphambi kokulinganisa.

2. Qinisekisa ukuba igumbi lokulinganisa lizolile, vumela umntu aphumle kancinci imizuzu emi-3-5 ngaphambi kokuba aqale ukulinganisa, kwaye qiniseka ukuba uyakuphepha ukuthetha ngexesha lokulinganisa.

3. Umntu oxilongwayo kufuneka abe nesitulo esineenyawo ezithe tyaba, aze alinganise uxinzelelo lwegazi lwengalo engasentla. Ingalo engasentla mayibekwe kumgangatho wentliziyo.

4. Khetha i-blood pressure cuff ehambelana nomjikelo wengalo yomntu ochaphazelekayo. Umlenze ongasentla wasekunene womntu ochaphazelekayo awuzange ubonakale, uqondile kwaye uthathwe malunga ne-45°. Umphetho ongezantsi wengalo engaphezulu ungaphezulu kwe-2 ukuya kwi-3 cm ngaphezulu kwe-elbow crest; i-blood pressure cuff akufuneki iqine kakhulu okanye ikhululeke kakhulu, ngokubanzi kungcono ukukwazi ukolula umnwe.

5. Xa kulinganiswa uxinzelelo lwegazi, umlinganiselo kufuneka uphindwe imizuzu eli-1 ukuya kwemi-2, kwaye ixabiso eliqhelekileyo lokufundwa oku-2 kufuneka lithathwe kwaye lirekhodwe. Ukuba umahluko phakathi kokufundwa okubini koxinzelelo lwegazi lwe-systolic okanye uxinzelelo lwegazi lwe-diastolic ungaphezulu kwe-5mmHg, kufuneka ulinganiswe kwakhona kwaye ixabiso eliqhelekileyo lokufundwa okuthathu kufuneka lirekhodwe.

6. Emva kokuba umlinganiselo ugqityiwe, cima i-sphygmomanometer, susa i-blood pressure cuff, uze ukhuphe umoya ngokupheleleyo. Emva kokuba umoya ose-cuff ukhutshiwe ngokupheleleyo, i-sphygmomanometer kunye ne-cuff ziyafakwa endaweni yazo.

Xa kulinganiswa i-NIBP, kusetyenziswa ii-cuff ze-NIBP rhoqo. Kukho iintlobo ezininzi zee-cuff ze-NIBP ezithengiswayo, kwaye sihlala sijongene nemeko yokungazi ukuba singakhetha njani. Ii-cuff ze-MedLinket NIBP ziye zayila iintlobo ezahlukeneyo zee-cuff ze-NIBP kwiimeko ezahlukeneyo zokusetyenziswa kunye nabantu, ezifanelekileyo kumasebe ahlukeneyo.

Iicuff zeReusabke NIBP ziquka iicuff zeNIBP ezikhululekileyo (ezifanelekileyo kwi-ICU) kunye neecuffs zoxinzelelo lwegazi lwe-nylon (ezifanelekileyo ukusetyenziswa kumasebe angxamisekileyo).

Iingenelo zemveliso:

1. Izinto zeTPU kunye ne-nylon, zithambile kwaye zikhululekile;

2. Iqulethe ii-airbag ze-TPU ukuqinisekisa ukuba umoya uqinile kwaye uhlala ixesha elide;

3. Ingxowa yomoya ingakhutshwa, kulula ukuyicoca nokubulala iintsholongwane, kwaye ingaphinda isetyenziswe.

Iicuff ze-NIBP ezilahlwayo ziquka iicuff ze-NIBP ezingalukwanga (zamagumbi otyando) kunye neecuff ze-TPU NIBP (zamasebe eentsana ezisandula ukuzalwa).

Iingenelo zemveliso:

1. I-NIBP cuff elahlwayo ingasetyenziselwa isigulane esinye, nto leyo enokuthintela ngempumelelo usulelo olusasazekayo;

2. Ilaphu elingalukwanga kunye nezinto zeTPU, zithambile kwaye zikhululekile;

3. I-cuff ye-NIBP yosana olusandula ukuzalwa enoyilo olucacileyo ilungele ukujonga imeko yolusu lwezigulane.
