BAVU, los yog phau ntawv resuscitator, yog ib yam khoom siv kho mob siv los ua pa rau tib neeg thaum muaj kev ua pa. Txhua qhov kev pabcuam xwm txheej ceev yuav tsum tau nruab nrog nws. Tshawb nrhiav seb BAVU siv li cas los cawm txoj sia.

BAVU, lossis Self-Filling Balloon nrog One-Way Valve, tseem hu ua phau ntawv resuscitator, yog cov cuab yeej siv kho mob siv thaum muaj xwm txheej ceev kom ua pa (xa cov pa oxygen) rau tus neeg uas nyob hauv qhov ua pa nres lossis muaj teeb meem ua pa hnyav. Nws yog qhov zoo dua txuas mus rau qhov chaw ntawm oxygen. BAVUs tuaj yeem pom hauv lub tsheb thauj neeg mob, tsev kho mob lossis chaw kho mob xwm txheej ceev. BAVU yog ib qho tseem ceeb raws li ib tug defibrillator. Cov cuab yeej kuj qee zaum hu ua "AMBU", hauv kev hais txog lub npe ntawm lub npe nrov. Nws tuaj yeem siv ib zaug lossis rov siv dua.

Muaj pes tsawg leeg

BAVU feem ntau yog tsim los ntawm:

• lub npog ntsej muag tsis muaj dej, muaj qhov sib txawv nyob ntawm tus neeg mob, yoog raws li cov duab ntawm lub qhov ncauj kom huab cua tsis khiav;
• ib txoj kev valve uas cais cov pa exhaled (Co2) los ntawm kev tshoov siab cua (oxygen);
• ib tug reservoir tank uas khaws cov pa oxygen thiab nce nws cov concentration. Qhov zoo tshaj plaws, nws tuaj yeem khaws cia txog 100% oxygen;
• lub siab nyem valve los tiv thaiv hyperventilation (tshwj xeeb tshaj yog nyob rau hauv cov me nyuam cov qauv);
• ib lub raj uas xa cov pa oxygen ncaj qha mus rau hauv tus neeg mob lub qhov ncauj;
• antibacterial filter (yeem).

Lub zais pa nws tus kheej nrog ib-txoj kev valve yog siv los xa cov pa oxygen mus rau cov pa ntawm tus neeg mob hauv kev ua pa nyuaj. Nws kuj tseem siv tau los thaiv cov hlab ntsws (ntshav, ntuav, thiab lwm yam). Qhov no yog cov cuab yeej kho mob npaj rau cov neeg teb xwm ceev thiab cov neeg ua haujlwm kho mob hauv tsev kho mob. Hauv qhov xwm txheej loj tshaj plaws, nws tuaj yeem ntxiv 100% ntawm cov pa oxygenation ua tsaug rau nws lub tank reservoir. Nws yog qhov yooj yim heev rau siv thiab tsis tas yuav muaj cov roj compressed, uas lav kev pom zoo siv rau txhua qhov xwm txheej.

Siv tau ntau dua li qhov ncauj qhov ncauj

Tau ntsib nrog lub plawv nres lossis ua tsis taus pa, BAVU muaj txiaj ntsig zoo dua li lub qhov ncauj ntawm qhov ncauj thiab nws tseem muaj kev nyab xeeb dua (yog li zam kom tsis txhob muaj kev pheej hmoo kis mob nrog tus cawm). Nws kuj tseem txhim kho kev ua haujlwm ntawm lub plawv thiab ua pa resuscitation thiab ua rau kom muaj txoj sia nyob. Nws tuaj yeem siv ntxiv rau lub defibrillator (tsis siv neeg lossis semi-automatic).

Nws kev ua tau zoo thiab kev siv yooj yim ua rau nws yog ib qho ntawm cov khoom siv kho mob uas siv ntau tshaj plaws.

Cov pej xeem txhawj xeeb lossis muaj kev pheej hmoo

BAVU tuaj yeem siv los cawm tus neeg raug tsim txom ntawm lub plawv nres ntxiv rau lub plawv zaws tab sis kuj tseem tuaj yeem cawm tus neeg raug tsim txom los ntawm kev poob dej. Lub resuscitator nrog lub ntsej muag oxygen tsim nyog thiab kev siv kom raug ua kom sai thiab ua haujlwm tau zoo los cawm tus neeg mob txoj sia uas raug kev txom nyem los ntawm kev tuag taus.

Cov theem ntawm kev ua haujlwm

BAVU yog ib qho cuab yeej siv tau ua haujlwm nrog ob txhais tes. Tus neeg cawm seej, tig thiab leaning ntawm tus neeg raug tsim txom, siv lub zog ntawm ib sab tes kom xa huab cua mus rau hauv txoj hlab pa thiab tsim cov pa oxygenation thaum nws tuav lub npog ntsej muag ntawm lub qhov ntswg nrog rau lwm tes thiab tus neeg mob lub qhov ncauj kom muaj lub foob zoo meej.

Namely: nyob rau hauv cov txheej txheem oxygenation, tus neeg cawm siav siv xib teg ntawm nws txhais tes thiab nws plaub ntiv tes kom oxygenate tus neeg mob. Tus ntiv tes xoo tsis tau siv hauv qhov haujlwm no. Nyob nruab nrab ntawm txhua qhov siab ntawm huab cua, tus neeg cawm siav yuav tsum xyuas seb tus neeg raug mob lub hauv siab puas nce.

Cov pa oxygenation ntawm tus neeg muaj kev ua pa nyuaj yog ua tiav hauv 4 theem:

1. Airway clearance
2. Qhov chaw ntawm lub qhov ncauj qhov ntswg los ntawm qhov ntswg mus rau lub puab tsaig
3. Insufflation
4. Exsufflation

Thaum twg siv nws?

BAVU yog siv ua ntej lossis tom qab intubation, thaum tos rau lub tshuab ua pa, thaum muaj xwm txheej ceev ntawm tus neeg mob plawv, thaum tos pab pawg resuscitation. Qhov tseeb tempo yog 15 ua pa ib feeb rau cov neeg laus thiab 20 mus rau 30 ua pa rau cov me nyuam mos los yog me nyuam mos.

Ceev faj kom ua

Lub BAVU yuav tsum tau siv nrog ob txhais tes, tshwj xeeb yog kom nws khaws cia ntawm qhov ncauj thiab qhov ntswg. Nyob rau hauv cov ntaub ntawv ntawm reusable BAVU, cov cuab yeej yuav tsum tau kom huv si tua kab mob (lub npog ncauj thiab valve nrog) tom qab siv txhua. Yog tias siv tsis raug, BAVU tuaj yeem ua rau ntuav, pneumothorax, hyperventilation, thiab lwm yam. Nws yog ib qho tseem ceeb kom paub siv nws.

BAVU yuav tsum tau ua kom haum rau tus neeg mob lub morphology. Lub npog ntsej muag uas loj dhau lossis me dhau tuaj yeem ua rau muaj ntau yam teeb meem. Resuscitators yog li ntawd muaj qhov ncauj qhov ntswg ntawm ntau qhov sib txawv xws li cov menyuam yug tshiab rau cov neeg laus. Lawv kuj yoog raws li kev tsim ntawm tus neeg mob.

Thaum yuav khoom, nws yuav tsum xyuas kom meej tias lub qhov ncauj qhov ntswg tau sib xws nrog BAVU hauv Tshuag.
