Kopema milinga mpe kozwa ngɛngɛ na monoxyde de carbone, lisalisi ya liboso¶

Kopema milinga mpe kozwa ngɛngɛ ya monoxyde de carbone aigu (\(\text{CO}\)) ezali bantina ya liboso ya liwa na mɔ́tɔ ya biloko oyo bizali na kati ya ndako mpe na makambo ya mbalakaka oyo epelisaka molunge, mpe ebomaka bato mbala misato koleka kozika na mɔ́tɔ ya libándá. Ntango mousse ya biloko ya ndako, ba tapis synthétiques, ba plastiques, mabaya, to ba carburants eziki to epeli milinga na kati ya chambre oyo ekangami, ebimisaka ba gaz oyo ezo chauffer mingi (\(150^\circ\text{C}\text{ to }500^\circ\text{C} / 300^\circ\text{F}\text{ to }900^\circ\text{F}\)) oyo kozikisa zolo ya likolo pembeni ya ba concentrations letale ya ba poisons systémiques invisibles: monoxyde de carbone (\(\text{CO}\)) na cyanure d'hydrogène (\(\text{HCN}\)). Mpamba te moto oyo abimi na ndako oyo etondi na milinga to oyo ezali kotanga na monoxyde de carbone akoki komonana lokola azali ekɛngɛ na ebandeli mpe na nsima kokwea miniti 30 na nsima wana nzela na ye ya mopɛpɛ oyo eziki ezali kovimba ekangamaka to hypoxie cellulaire ekómaka makasi, kobimisa mopɛpɛ ya pɛto nokinoki, kotya nzela ya mopɛpɛ na esika oyo ezali semba, mpe mbala moko oxygène oyo ezali koleka mingi na 100 % oyo euti na minganga ya lisalisi ya monganga ezali na ntina mingi.

Motambwisi oyo etambolisaka yo litambe na litambe na nzela ya kobimisama ya moto oyo azali na likama te kozanga ete okóma moto ya mibale oyo azwi mpasi, koyeba ete nzela ya mopɛpɛ ya molunge oyo ezali koya (stridor), mpo na nini ba oxymètres ya pulsation ya nsɔngɛ ya misapi epesaka lokuta oyo ebomaka 99% botangi na ntango ya empoisonnement ya monoxyde de carbone, kosala CPR na ba pema ya kobikisa mpo na kokangama ya asphyxie, mpe kolandela mpo na mayi oyo ezongisami retard na mimpululu na boumeli ya ngonga 48 oyo ekolanda.

Sala boye sikoyo¶

1. Mibatela liboso , kota ata moke te na esika ya kokangama oyo ezali kozika to oyo etondi na CO kozanga aparɛyi ya kopema. Kozonga mbangu te na kati ya ndako oyo etondi na milinga, sous-sol, to garage oyo ekangami na générateur to motuka oyo ezali kosala. Monoxyde de carbone oyo emonanaka te mpe cyanure d’hydrogène ekoki kobɛta moto oyo abikisaka mpe ayeba te na mpema mibale. Benda moto oyo azwi mpasi kaka soki okoki kokóma epai na bango mbala moko longwa na ekuke oyo efungwami ntango ozali kotikala na nse na nse ya milinga.
2. Kokende na moto nyonso na mopepe ya sika ya libanda ata na ntaka ya mɛtrɛ 15 kino 30 (50 kino 100 feet) mosika. Bimisa moto yango mobimba na ndako (kaka te na nzela ya koleka to garage ya polele) na mopepe ya libanda ya polele, oyo ezali kotambola mosika na bisika ya milinga to bisika ya kobimisa mopepe.
3. Benga nimero ya urgence ya esika ofandi mbala moko mpe senga oxygène oyo ezali koleka mingi. Benga nimero ya urgence ya esika ofandi (911 na Etats-Unis mpe Canada, 112 na Union européenne mobimba, 999 na Royaume-Uni) to tala ya biso banimero ya mbalakaka répertoire. Yebisa na dispatcher spécifiquement que ozali na victime ya inhalation ya milinga to ya empoisonnement ya monoxyde de carbone yango wana ba dispacher ba paramédicaux équipés na ba masques non rebreathers ya oxygène 100 pour cent, ba équipements ya intubation, na ba antidotes Cyanokit (hydroxocobalamine).
4. Tala réponse mpe positionner nzela ya mopepe malamu:
   • Soki azali na conscience mpe azali kopema: Fandisa mutu semba to semi-semba na angle ya 45 à 90 degrés (kogumbama mwa liboso na mabolongo na ye soki azali na pema mokuse). Kofanda semba esalelaka nguya ya kobenda biloko mpo na kopekisa kovimba ya zolo mpe ya nsinga ya mongongo.
   • Soki bazali koyeba te kasi bazali kopema malamu: Rouler bango na mopanzi na bango na Position ya récupération mpo monoko na bango ekanga nzela ya mopepe te mpe kosanza nyonso ebima na monoko.
   • Soki ozali ko répondre te mpe ozali kopema te (to kaka kopema): Bandá CPR ya CPR mbala moko na 30 compressions ya ntolo elandi na 2 pema ya kobikisa.
5. Bofungola bilamba ya seresere na nkingo mpe bomba moto mobimba kimia. Fungola bouton ya ba cols ya chemise, ba cravate, ba ceintures, mpe ba vestes, mpe kotika te moto atambola to asala makasi. Koningana ya nzoto ebakisaka rythme cardiaque mpe consommation ya oxygène, ezo circulation ya monoxyde de carbone na cyanure noki na muscle ya motema mpe na cerveau.
6. Kopesa ELOKO TE na monoko (mai te, ba chips ya glace, to bilei te) soki bapemaki milinga ya moto. Ata soki zolo ya moto yango ekauki mpe eziki, kotika ye te amela mayi; komela na nzela ya larynx oyo ezali kobimisa bampota ekoki kobimisa spasme ya mbalakaka ya nsinga ya mongongo oyo ebomaka (laryngospasm) to kobimisa kosanza oyo ebomaka ntango basali ya lisalisi ya liboso bakɔtisi nsinga ya kopema ya nokinoki mwa miniti nsima.

The 3 simultaneous injury mechanisms of smoke inhalation¶

Why can a person walk out of a house fire without a single burn mark on their skin and still suffer life-threatening respiratory failure an hour later? Because indoor fire smoke attacks the human body through three separate mechanisms at the same time:

Koyeba kozika ya molunge ya nzela ya mopɛpɛ ya likoló liboso ete zolo evimba ekangama¶

Mopepe ya kokauka oyo epelisami ezali mpenza mokumbi malamu ya molunge, yango wana ntango moto azali kopema milinga ya molunge ya kokauka, ba muqueuses humides ya zolo, ya monoko, mpe ya zolo ezwaka pene na 100% ya nguya ya molunge yambo mopepe eleka na nse ya bansinga ya mongongo (longola se moko monene: vapeur vivant, oyo ememaka mbala 4.000 ya makoki ya molunge ya mopɛpɛ ya kokauka mpe ezikaka tii na nse tii na ba bronchioles ya mozindo ya mimpululu).

Lokola zolo ya likoló emɛlaka molunge wana nyonso, misisa oyo ezali zingazinga ya épiglotte mpe misisa ya mongongo ekómaka na mai mpe evimbaka nokinoki (œdème), kaka lokola libungutulu oyo ezali komata na lobɔkɔ oyo eziki. Na mokóló, eteni oyo eleki moke ya nsinga ya mopɛpɛ na bansinga ya mongongo (glottic opening) ezali bobele na bonene ya mwa bamillimɛtrɛ (mpe epai na mwana, bonene ya mosapi na bango ya moke). Soki kovimba ekitisaka diamètre wana ya nzela ya mopepe na katikati, résistance ya kopema emati mbala 16 (na mobeko ya Poiseuille ya quatrième puissance).

Tala mbala moko oyo abiki na moto nyonso mpo na "5 Drapeaux Rouges ya Kozika na nzela ya mopepe".¶

1. Nsuki ya zolo oyo eyemba to kozika zingazinga ya mbɛbu, zolo, mandefu, to mandɛfu.
2. Sputum carbone: Souille ya moindo oyo ezipaka monoko, mino, to sima ya zolo, to kosopa saliva ya gris/black-flecked.
3. Koganga to mbongwana ya mongongo: Senga moto aloba kombo na ye pe apema. Soki mongongo na bango eyokani na raspy, squeaky, muffled ("mongongo ya pomme de terre ya moto"), to ekiti na mongongo ya nse, kovimba esi ebandi na ba cordes vocales.
4. Difficulté ya komela saliva (dysphagia) to kobwaka mai.
5. Inspiratory Stridor: Makɛlɛlɛ ya makasi, ya makasi ya koganga, ya kofinga, to ya kopema oyo eyokamaka kozanga stéthoscope ntango moto yango azali kopema na kati. Stridor ezali urgence médicale ya makasi, elakisi que tuyau ya mopepe ezali déjà 70 à 80 pour cent evimbi ekangami mpe ekoki kokangama mobimba na ba minutes.

Action ya secours ya liboso mpo na ba suspects ya kozika ya voie respiratoire:

• Bomba mutu afandi bolt vertical (45 à 90 degrés), jamais lalisa ye plat na mukongo, po kolala plat ematisaka makila ya veineux oyo esanganaka na kingo pe esala que gorge evimba noki.
• Pesá zéro mayi, glace, to bilei na monoko (pangusa mbɛbu oyo ekauki kaka na elamba ya mai).
• Benga 911 / 999 / 112 zonga mbala moko soki stridor to hoarseness ebandi kokola mpo ete équipage ya paramédique ya Advanced Life Support (ALS) ekoka kosala intubation na ebandeli yambo ya kokangama ya nzela ya mopepe.

Monoxyde de carbone (CO) na Cyanure d'hydrogène (HCN): "Ba mapasa ya poison".¶

Atako milinga ya moto ya structure ezali na ezala monoxyde de carbone mpe cyanure d’hydrogène, pure empoisonnement ya monoxyde de carbone esalemaka mpe mikolo nyonso kozanga moto to milinga ata moke te, uta na ba générateurs ya essence portable oyo etambolaka na ba garages to pene na ba fenêtres, ba flues ya four oyo ekangami, ba chauffe-eau ya gaz oyo ezali na ba vents ya sima, ba grilles ya makala ya kati to ba chauffe-eau ya propane, mpe mituka oyo ezali kosala mosala te na kati oyo ekangami ba garages na ba garages.

Pourquoi Monoxyde de carbone + Cyanure d'hydrogène ezalaka letale boye ensemble¶

1. Monoxyde de carbone (\(\text{CO}\)) ebɛti mbala misato:
   • Ya liboso, \(\text{CO}\) ekangamaka na ba atome ya fer oyo ezali na hémoglobine ya ba cellules rouges mbala 200 to 250 makasi koleka oxygène, mpe esalaka carboxyhémoglobine (\(\text{COHb}\)) na boye ete ba globules rouges ekoki kozwa oxygène na mimpululu te.
   • Ya mibale, soki molécule moko \(\text{CO}\) ekangami na proteine ​​ya hémoglobine, ebongoli forme structurelle ya ba sites misato mosusu oyo ekangamaka na oxygène (Effet Haldane / déplacement gauche ya courbe ya dissociation ya oxyhémoglobine), kopekisa makila etika oxygène oyo ezali na yango na ba tissus ya cerveau mpe ya motema oyo ezali na nzala.
   • Ya misato, \(\text{CO}\) ekangamaka na myoglobine cardiaque na kati ya misisa ya motema yango moko, ekitisaka mbala moko makasi ya pompe ya motema mpe ebimisaka ba arrhythmies ya likama.
2. Cyanure d'hydrogène (\(\text{HCN}\)) bokangami ya ba cellules:
   • Tango nionso canapé ya mikolo oyo, matela ya mousse polyuréthane, tapis, to appareil ya plastique ezo bima milinga na moto ya ndaku, ebimisaka gaz cyanure d'hydrogène.
   • Inhaled cyanide enters the bloodstream and binds to the ferric iron (\(\text{Fe}^{3+}\)) in cytochrome c oxidase inside every cell's mitochondria, shutting down aerobic cellular respiration in seconds. Even if oxygen is present in the blood, the cells cannot use it, forcing the body into fatal anaerobic lactic acidosis and sudden collapse.

Symptoms of Carbon Monoxide poisoning by blood COHb level¶

Ndenge nini 100% Oxygène Médical na Oxygène Hyperbarique ebikisaka cerveau¶

Pourquoi victime ya inhalation ya monoxyde de carbone to milinga akoki kaka te "kofanda libanda na veranda na mopepe ya malamu pendant demi heure pe kozonga na mbeto" au lieu ya komata na ambulance?

Tala fiziki ya ntango boni esɛngaka mpo na kosukola monoxyde de carbone na hémoglobine oyo ezali na ngɛngɛ (the \(\text{COHb}\) Elimination Half-Life):

• Kopema mopepe ya ndako ya libanda ya momesano (\(21\%\text{ Oxygène}\) na atmosphère 1): Demi-vie ya carboxyhémoglobine ezali 4 à 6 heures (elingi koloba soki niveau ya makila na yo ezali 40 pour cent, sima ya ngonga 5 ya kofanda na veranda ezali kaka na 20 pour cent ya poison, kokoba kosala peroxydation ya lipide ya cerveau mpe kobebisa motema butu mobimba).
• Kopema \(100\%\text{ Oxygène médical ya flux ya likolo}\) na nzela ya Masque Non-Rebreather ya paramédique ya seresere (\(15\text{ L/min}\)): Ezali kokata demi-vie mbala minei kino na 60 kino 90 minutes.
• Na kati ya Chambre ya Thérapie Hyperbarique d’Oxygène (\(\text{HBOT}\)) ya lopitalo (\(100\%\text{ Oxygène}\) na \(2.5\text{ kino }3.0\text{ Atmosphères}\) ya pression): Ekati demi-vie na se kaka 20 à 30 minutes, e dissoudre oxygène ya peto ekoki directement na plasma ya makila ya mayi mpo na kobatela cerveau na motema na bomoi kozanga kutu kozala na mposa ya ba globules rouges, mpe epekisaka ba globules blancs ebundisa myéline ya cerveau (kopekisa Séquelles Neurologiques retardées / DNS, syndrome ya mabe ya kobungisa bokundoli, koningana lokola Parkinson, mpe mbongwana ya bomoto oyo ekoki kosala mikolo 2 kino 40 nsima ya empoisonnement ya CO oyo ezwami te).

Antidote ya lopitalo mpo na empoisonnement ya Cyanide oyo euti na milinga ya mɔtɔ (Hydroxocobalamin) .¶

Tango ba paramédicaux to minganga ya urgence basalisi victime oyo abendami ayeba te na milinga ya structure ya kati (oyo azali na souille na monoko, confusion/coma, to lactate ya makila mingi), bapesaka antidote intraveineux oyo babengi Hydroxocobalamin (Cyanokit), précurseur concentré ya Vitamine B12a. Hydroxocobalamine ekangamaka mbala moko na ba ions cyanure toxiques na kati ya makila mpo na kosala cyanocobalamine (Vitamine B12 régulière) oyo ezali mpenza mabe te, oyo ebimisamaka na likama te na makila (ebalusaka makila mpe loposo ya mobɛli mpo na mwa ntango oyo ezali na likama te na motane-rose na boumeli ya mwa mikolo).

Kosalisa contamination ya miso ya moninga, loposo, mpe bilamba¶

When someone escapes a smoky fire:

1. Flush smoke-irritated eyes with clean water or saline: Acid gases and soot particles trapped under the eyelids cause severe chemical conjunctivitis and corneal burns. Once breathing is stable, gently rinse stinging eyes with clean lukewarm tap water, bottled drinking water, or sterile saline eyewash for 10 to 15 minutes from the inner corner (near the nose) outward, and remove contact lenses as soon as possible.
2. Cool any skin burns and remove soot-soaked outer clothing: If clothing is hot or smoldering, douse with cool clean water for 20 minutes (never use ice or butter on burns; see our burns and scalds first aid guide). Once out of danger, remove heavy outer jackets or sweaters saturated with toxic plastic soot so the person stops inhaling off-gassing chemicals from their own collar, and wrap them in a clean dry blanket to prevent hypothermia.

The 24-to-48-Hour Delayed Lung Edema Watch¶

Even if an emergency physician clears a mild smoke-exposure patient to go home after a few hours of oxygen observation, toxic chemical gases like phosgene and hydrochloric acid have a latent "time-bomb" period of 12 to 48 hours before deep lung inflammation peaks.

Monitor the person closely for the next 2 full days (and over the next 4 weeks for carbon monoxide neurological changes). Return to the Emergency Department immediately if any of these warning signs appear:

• New or worsening shortness of breath at rest or when walking across a room.
• Inability to lie flat in bed (orthopnea) kozanga koyoka lokola bazali ko étouffer to kosekwa.
• Kopema, kokangama ya ntolo, to makelele ya koganga/kobukana na mai tango ozali kopema.
• Coughing up pink, frothy, or blood-streaked mucus (classic sign of delayed pulmonary edema fluid leaking into the air sacs).
• Fever, chills, or thick yellow-green sputum (secondary bacterial pneumonia after smoke damage to airway cilia).
• New headaches, memory lapses, confusion, dizziness, irritability, or unsteady balance days or weeks after carbon monoxide exposure. For preventing future leaks and fires, review our carbon monoxide leaks and alarms mpe house fire escape and survival batambwisi.
