Pulseless hluav taws xob ua haujlwm (PEA) yog ib qho kev kho mob uas tshwm sim los ntawm kev tsis ua haujlwm thiab tsis muaj palpable pulse nyob rau hauv lub xub ntiag ntawm lub plawv hluav taws xob ua haujlwm. Pulseless hluav taws xob ua haujlwm yav dhau los tau raug hu ua electromechanical dissociation (EMD). (Saib Etiology.)
Puas pulseless hluav taws xob ua haujlwm poob siab?
Ts. Rhythms uas yog tsis tuaj yeem ua rau poob siab suav nrog kev ua haujlwm tsis muaj hluav taws xob (PEA) thiab asystole. Hauv cov xwm txheej no, txheeb xyuas qhov tshwm sim thawj zaug, ua tau zoo CPR, thiab muab tshuaj epinephrine tsuas yog cov cuab yeej uas koj yuav tsum tau resuscitate tus neeg mob.
Kev kho hluav taws xob tsis muaj zog li cas?
Kev Kho Mob / Kev Tswj Xyuas
thawj kauj ruam hauv kev tswj cov hluav taws xob tsis muaj zog yogpib lub hauv siab compressions raws li kev txhawb nqa lub plawv siab(ACLS) raws tu qauv ua raws li kev tswj hwm epinephrine txhua 3 mus rau 5 feeb, thaum tib lub sij hawm nrhiav ib qho kev rov qab los.
Yuav ua li cas 2 feem ntau ua rau lub cev tsis muaj zog hluav taws xob?
Hypovolemia thiab hypoxia yog ob qho laj thawj ntawm PEA. Lawv kuj yog qhov yooj yim tshaj plaws thim rov qab thiab yuav tsum nyob rau saum toj ntawm txhua qhov kev kuaj mob sib txawv.
Koj tuaj yeem txheeb xyuas qhov kev ua haujlwm tsis muaj hluav taws xob ntawm lub ECG li cas?
- Kauj Ruam 1: Txiav txim siab seb PEA yog nqaim (QRS ntev <0.12) lossisdav (QRS ntev ≥0.12) ntawm ECG saib.
- Kauj Ruam 2: Nquag- nyuaj PEA feem ntau yog vim muaj teeb meem kev siv tshuab los ntawm txoj cai ventricular inflow lossis outflow obstruction.

Dab tsi yog qhov txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob?
Gramophone: Txhua lub suab kaw suab, lossis cov cuab yeej ua si yav dhau los-cov suab kaw, tshwj xeeb tshaj yog tias nws siv lub tiaj tiaj tiaj. Phonograph: Txhua lub suab kaw suab, lossis cov cuab yeej siv rau kev ua si cov suab uas tau kaw dhau los, tshwj xeeb tshaj yog tias nws siv lub tog raj kheej tig.
Puas yog kev siv hluav taws xob siv hluav taws xob?
Usability engineering yog kev qhuab qhia uas tsom mus rau kev txhim kho kev siv tau ntawm kev sib tham sib. Nws rub tawm cov kev xav los ntawm kev tshawb fawb hauv computer thiab kev puas siab puas ntsws los txhais cov teeb meem uas tshwm sim thaum siv cov kab ke.
Lub tshuab hluav taws xob loj npaum li cas rau qhov chaw nres tsheb tsis muaj hluav taws xob?
Nrhiav lub rhaub nrog BTU tso zis uas phim koj cov txiaj ntsig. Piv txwv li, yog tias koj qhov chaw nres tsheb tsis muaj hluav taws xob yog 484 square feet, koj cov qauv yog 484 / 200 x 9, 000, lossis 21, 780. Koj xav tau lub rhaub nrog tsawg kawg yog 21, 780 BTU tso zis.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
