Mechanical tuag qhov chaw roj yog thawj cov pa nqus thaum pib ntawm txhua txoj kev ua pa. Raws li cov qhov chaw neeg kho tshuab tuag ntim nce, tsawg dua cov pa tshiab tuaj yeem txav mus rau hauv tus neeg mob lub alveoli los koom rau hauv kev sib pauv roj.
Raws li, qhov cua tshuab ua kom qhov chaw tuag mus li cas?
Cov Khoom Siv Hluav Taws Xob : Tub los ntawm lub tshuab ua pa nce qhov chaw tuag ntim los ntawm kev ntxiv ntim rau qhov ua tau zoo qhov chaw tsis koom nrog hauv kev sib pauv roj. PEEP: Ntau tshaj PEEP tuaj yeem dhau-distend alveoli thiab ua rau lub ntsws barotrauma, nce ntxiv cov qhov chaw tuag ntim.
Ib tus kuj yuav nug, yuav ua li cas qhov nce hauv qhov chaw tuag cuam tshuam rau koj ua tsis taus pa? Tuag chaw tau hnyav heev ua tsis taus pa vim cov txo qis hauv thaj chaw muaj rau kev nthuav dav roj. Raws li qhov tshwm sim, cov tus nqi ntawm cov pa oxygen hauv cov ntshav txo qis, qhov cov qib carbon dioxide nce . Qhov no yog qhov tshwm sim ntawm hydrostatic rog ua ke nrog cov cov nyom ntawm txoj hlab pa.
Yooj yim li ntawd, dab tsi ua rau qhov chaw tuag?
Lub alveolar qhov chaw tuag yog ua los ntawm qhov cua / perfusion tsis sib npaug ntawm qib alveolar. Feem ntau ua nce ntawm alveolar qhov chaw tuag yog kab mob hauv lub ntsws-haus luam yeeb, mob ntsws, mob ntsws, thiab mob hawb pob. Lwm yam ua suav nrog pulmonary embolism, pulmonary hypotension, thiab ARDS.
Qhov chaw tuag cuam tshuam li cas rau qhov ntim dej?
Qhov chaw tuag yog qhov ntawm txhua tus tidal ntim uas ua tsis koom nrog kev pauv roj. Yog li, piv txwv li ib txwm tidal ntim ntawm 500 ml, kwv yees li 30% ntawm huab cua no yog "nkim" hauv qhov kev nkag siab tias nws ua tsis koom nrog kev pauv roj.

Qhov alveolar deadspace yog tshwm sim los ntawm kev tso pa tawm/qhov tsis sib xws ntawm qib alveolar. Feem ntau ua rau nce alveolar deadspace yog kab mob hauv lub ntsws-haus luam yeeb, mob ntsws, mob ntsws, thiab mob hawb pob. Lwm qhov ua rau muaj xws li pulmonary embolism, pulmonary hypotension, thiab ARDS
