Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Kuwana O2 mumhepo ndicho chinangwa chinokosha chokufema, naizvozvo kuwedzera okisijeni kunoshandiswa mukurapa. Kurapa kwacho hakungowedzeri mwero weoxygen muropa romurwere chete, asi kunoderedzawo kusagadzikana kweropa mumapapu akawanda anorwara, zvichiita kuti mwoyo usashanda zvakaoma. Oxygen therapy inoshandiswa kurapa emphysema, pneumonia, zvimwe zvirwere zvemoyo (congestive heart failure), zvimwe zvirwere zvinokonzera kuwedzera kwepulmonary artery pressure, uye chero chirwere chinokanganisa kukwanisa kwemuviri kutora uye kushandisa gasi reokisijeni. Kurapa kunochinjika zvakakwana kuti zvishandiswe muzvipatara, kumba kwemurwere, kana kuwedzera nemidziyo inotakurika. Oxygen matende aimboshandiswa zvakanyanya mukuwedzera okisijeni, asi kubvira ipapo yakatsiviwa zvakanyanya nekushandiswa kwemasiki eoksijeni kana cannulas yemhino. Hyperbaric (yakakwira-kumanikidza) mushonga unoshandisa makamuri eoksijeni akakosha kuwedzera kumanikidzwa kweO2 kutenderedza murwere uye, pazvinenge zvichidikanwa, vashandi vezvokurapa. Kupindwa muropa necarbon monoxide, gas gangrene, uye decompression sickness (iyo 'bends') dzimwe nguva zvinotarisirwa neiyi kurapa. Kuwedzera kweO2 mumapapu kunobatsira kubvisa carbon monoxide muboka rehemoglobin. Oxygen gasi ine chepfu kumabhakitiriya ane muchetura anokonzera gas gangrene, naizvozvo kuwedzera kumanikidzwa kwayo kunobatsira kuuraya. Chirwere chokudzvinyirira chinoitika kuvanyururi vanodzvinyirira nokukurumidza zvikuru pashure pokudonha, kuchiguma nokuumbwa mumaropa kwemabhururu egasi risina simba, zvikurukuru nitrogen nehelium. Kuwedzera kumanikidzwa kweO2 nokukurumidza sezvinobvira kunobetsera kunyungudutsa mabhuru acho kudzokera muropa kuitira kuti aya magasi akawandisa agone kufemerwa nenzira yomuzvarirwo kupfurikidza nemapapu.  Mubvunzo: Kurapa kwacho kunoderedza sei basa romwoyo?
