Pulmonary edema chirwere chakakomba chinokonzerwa nemvura inowanikwa munzvimbo dzemapapu emapupa uye alveoli kunze kwemidziyo yeropa yemapinmoni, iyo inotungamirira kumapfupa asina simba mapapu. Izvo zvinoitika apo, pane nzvimbo yemhepo, mapapu anotanga kuzadza ne serous fluid, inobuda mumidziyo. Izvi zvinogona kunge zvakakonzerwa nekudzvinyirira kukuru mumidziyo yeropa, kushaya mapuroteni muropa, kana kusakwanisa kuchengetedza mvura mumapulama.
Zviratidzo zvemoyo wepachimusi chemafi uye mapirmita edema
Zvinonyanya kukosha kwekusiyana kwezviratidzo zve interstitial pulmonary edema uye alveolar pulmonary edema, iyo inofananidzwa sezvikamu zviviri zvehutano hwehutano.
Ne interstitial pulmonary edema, iyo inofanana nezviratidzo zvepfungwa yemweya, mvura inopinda inopinda mumapapu ose emapapu. Izvi zvinonyanya kukuvadza mamiriro ekugadzirisa okisijeni uye carbon dioxide pakati pemhepo yealveoli neropa, zvinokonzera kuwedzera mumapurmonary, vascular and bronchial resistance. Kurwiswa kwemoyo wepachimusi (soul intermedial pulmary edema) kunowanzoitika kakawanda usiku kana kuti zuva risati rasvika. Murwere anomuka kubva pakufunga kwekushayiwa mhepo, anotora kukamanikidzwa kugara, anofara, anonzwa kutya. Kunoita kupfupika kwemhepo, paroxysmal chikwama, cyanosis yemiromo uye misumari, kupora kwemaoko, kuwedzerwa kweropa, tachycardia. Nguva yekurwisa kwakadaro inobva pamaminiti akawanda kusvika maawa akawanda.
Kubudirira kwekupedzisira kwehutano, hunobatanidzwa nekupinda mukati memvura inopinda mumugwagwa wealveoli, kunotungamirira kuodheolar edema yemapapu. Mvura inotanga kuparadza zvinhu zvinodzivirira, izvo zvinogadziridza arveoli kubva mukati, kuitira kuti chidimbu chirambe chakabatana pamwe chete, chakasvibiswa nehuwandu hwemvura. Panguva ino, puroteni yakagadzikana yemapurogiramu, iyo inotanga kuvhiringidza lumen yebronchi, iyo inotungamirira kuderera kwehupenyu hwehupenyu muropa uye hypoxia. Alveolar edema yemapapu inoratidzirwa nehupamhi hwekupemha kusakwanisa, dyspnea yakaoma nemararamiro akasiyana, cyanosis, unyoro hweganda. Pamiromo inowanikwa mhutu ane tinge yakapfava nekuda kwekuvapo kwezvinhu zveropa. Kazhinji kuziva kwevarwere kunokanganiswa, coma inogona kuuya.
Mafomu emarimita edema
Zvichienderana nechinokonzera uye chinotangira, chirwere chepfungwa uye kwete-cardiogenic pulmonary edema yakasarudzwa.
Cardiogenic pulmonary edema inowanikwa muzvirwere zvemoyo uye, sekutonga, yakaoma. Iyo inogona kuva kuratidzwa kwekusiya ventricular moyo kusagadzikana mu myocardial infarction, cardiomyopathy, mitral insufficiency, aortic mwoyo chirwere, uye mitral stenosis nezvimwe zvirwere. Muchiitiko ichi, kuwedzera kwehydrostatic inodzvinyirira mumapurmonary capillaries inokonzerwa nekuwedzera kwekumanikidzwa mumapurmonary vein, inokonzera edema.
Kwete-cardiogenic pulmonary edema inokonzerwa nekuwedzera kwemavhinga ekuputika kwemapapu, izvo zvinotungamirira kupinda kupinda mukati memapurmonary nzvimbo. Inogona kuenzaniswa nedzimwe mamiriro ekurapa:
Panewo podemoni inonzi edema inokonzerwa nekuita kwezvinhu zvinotyisa pamapapu emapapu. Kazhinji kacho chiitiko ichi chinokonzerwa nehupfu ye nitrogen oxides. Munguva iyi, zvikamu zvakasiyana-siyana zvinozivikanwa: reflex, danho rezvinhu zvakavanzika, kliniki uye kushanduka kwekuvandudza. Pakutanga kwekutanga, pane kugadzirisa kunofadza pasi pekuita kwezvinhu: kushatirwa kwemukoma membrane, kukwezva, uye kurwadziwa mumaziso. Uyezve, zviratidzo zvinonyangarika, chikamu chinotadza chinoitika, chinogara kubva maawa maviri kusvika pazuva. Zvadaro pane zviratidzo zvakadai sokuwedzera kufema, kukwezva kunonaya ne wheyzing, cyanosis, tachycardia. Muzviitiko zvakanyanyisa uye nekurapa panguva yakakodzera pazuva rechitatu mushure mekushaya chepfu, mamiriro acho ezvinhu anowanikwa.
