Chii chinokonzera kunyura?

Kunyura mumushonga kunoreva chimiro cheacute asphyxia chinokonzerwa nemuchina chinokonzera kunze kwemuviri, chinounzwa nenyaya yekuti pulmonary alveolar space - inowanzogarwa negasi - inogarwa zvishoma nezvishoma nemvura (semuenzaniso mvura yemunyu kana iri kuputika. kunyura mugungwa kana mvura ine chlorine kana ichinyura mudziva rekutuhwina).

Chikonzero chekufa mukunyura ndeye hypoxaemia inotungamirira ku acute hypoxia, iyo inoguma nekukanganisa kushanda kunyanya muuropi uye myocardium nekurasikirwa kwekuziva, kukanganisa kwemoyo wakarurama uye kusungwa kwemwoyo.

Panguva imwe chete, hypercapnia (yakawedzera carbon dioxide concentration muropa) uye metabolic acidosis inoitika.

Hypoxemia inokonzerwa nekupinda kwemvura mumapapu uye / kana laryngospasm (kuvharwa kwe epiglottis, iyo inodzivirira mvura asiwo mhepo kupinda).

Zvikamu zvina zvinofanotaura rufu nekunyura

Kufa nekunyura kunotangirwa nematanho mana kana nhanho:

1) Nhanho kana nhanho yekushamisika: inotora masekonzi mashoma uye inoratidzwa nekukurumidza inhalation, zvakadzika sezvinobvira, munhu asati aenda pasi pemvura.

Zvinoitika zvakare:

• tachypnea (kuwedzera kufema chiyero);
• tachycardia;
• arterial hypotension ('low blood pressure');
• cyanosis (bluish ganda);
• miosis (kuderedza dhayamita yemwana weziso).

2) Danho rekudzivirira kana danho: rinotora maminetsi maviri uye rinoratidzwa nekutanga apnoea, panguva iyo munhu anodzivirira mvura kuti isapinda mumapapu nekufema uye anonetsekana paanenge achiedza kumuka, kazhinji nekutambanudza maoko avo pamusoro pemusoro wavo munzira. pamusoro pemvura.

Muchikamu ichi, zvinotevera zvinoitika zvishoma nezvishoma:

• apnea;
• kutya;
• kukurumidza kufamba mukuedza kumukazve;
• hypercapnia;
• BP;
• kusunungurwa kwakanyanya kweadrenaline mukutenderera;
• tachycardia;
• kukanganisa kwekuziva;
• cerebral hypoxia;
• kugwinha;
• kuderedza motokari reflexes;
• sensory alteration;
• sphincter kusunungurwa (tsvina uye/kana weti inogona kuburitswa zvisina kufanira).

Kana nyaya yacho yapera mweya mumapapu nekufema, mvura inopinda nemunzira dzemhepo ichikonzera apnea inokonzerwa nekuvharwa kwe epiglottis (laryngospasm), kuita kwakagadzirirwa kuchengetedza nzira yekufema kubva mumvura asi iyo zvakare inodzivirira kupfuura kwemhepo.

Hypoxia uye hypercapnia zvinozokurudzira nzvimbo dzetsinga kuitira kuti utangezve kufema: izvi zvinotungamira kuvhurika kamwe kamwe kweglottis nekuzotevera kupinda kwehuwandu hwemvura mumapapu, kuvharika kwekutsinhana kwegasi, kushandurwa kwesurfactant, kudonha kwealveolar nekusimudzira. ye atelectasis uye shunts.

3) Apnoeic kana 'inooneka rufu' nhanho kana chikamu: inotora anenge 2 maminetsi, umo kuedza kumuka, pasina, kunoderedzwa kusvika iyo nyaya inoramba isingafambi.

Iyi nhanho inoratidzwa zvishoma nezvishoma ne:

• kugumisa kufema chaiko
• miosis (pupil constriction);
• kurasikirwa kwekuziva;
• kuzorora kwemhasuru;
• bradycardia yakaoma (inononoka uye isina simba kurova kwemoyo);
• idya.

4) Terminal kana 'gasping' nhanho: inotora inenge 1 miniti uye inoratidzwa ne:

• kurasika kwakaramba kuripo
• yakanyanya cardiac arrhythmia;
• kusungwa kwemoyo;
• rufu.

Iyo anoxia, acidosis uye electrolyte uye haemodynamic kusaenzana kunokonzerwa neasphyxia zvinotungamira mukukanganisika mutinhimira kusvika pakusungwa kwemoyo uye kufa.
