Yintoni i-nitrogen narcosis?

I-nitrogen narcosis yimeko echaphazela ukwahluka kolwandle. Ihamba ngamanye amagama amaninzi, kubandakanya:

• nark
• ayobe enzonzobileni
• Impembelelo yemartini
• igesi egalelwe ngaphakathi

Ukuntywila kulwandle olunzulu basebenzisa iitanki zeoksijini ukubanceda baphefumle phantsi kwamanzi. Ezi tanki zihlala zinomxube weoksijini, initrogen, kunye nezinye igesi.Emva kokuba abanye bebhukuda ngaphantsi kweenyawo ezili-100, ukunyuka kwengcinezelo kunokuguqula ezi zinto. Xa uphefumlelwe, ukutshintsha kwegesi kunokuvelisa iimpawu ezingaqhelekanga ezihlala zisenza ukuba umntu abonakale enxilile.

Ngelixa i-nitrogen narcosis yimeko yexeshana, inokuba neziphumo ezibi kwezempilo. Funda ukuze ufunde kabanzi malunga neempawu ze-nitrogen narcosis kunye nokuba wenze ntoni ukuba wena okanye omnye umntu unamava kuwo.

Ziintoni iimpawu ze-nitrogen narcosis?

Uninzi lweentlobo ezichazayo luchaza i-nitrogen narcosis njengokuziva ngathi abanxilanga okanye badidekile. Abantu abane-nitrogen narcosis bahlala bebonakala njalo nakwabanye.

Iimpawu eziqhelekileyo ze-nitrogen narcosis zibandakanya:

• isigqibo esingalunganga
• ukulahleka kwememori yexesha elifutshane
• ingxaki yokujonga
• imvakalelo yovuyo
• ukudideka
• ukunciphisa ukusebenza kwentliziyo kunye nemisipha
• Ukugxininisa kwindawo ethile
• nemibono

Iimeko ezinzima kakhulu zinokubangela ukuba umntu angene kwi-coma okanye asweleke.

Iimpawu ze-nitrojeni ze-narcosis zihlala ziqala ukuba i-diver divers ifike kubunzulu beenyawo ezili-100. Ababi mandundu ngaphandle kokuba lo mdadayo udada ngokunzulu. Iimpawu ziqala ukuba nzulu kubunzulu obumalunga neenyawo ezingama-300.

Emva kokuba i-diver diver ibuyele emanzini, iimpawu zihlala zihamba phakathi kwemizuzu embalwa. Nangona kunjalo, ezinye zeempawu, njengokudideka kunye nokugweba okungafanelekanga, kubangela ukuba abo badadayo badade ngokunzulu. Oku kunokukhokelela kwiimpawu ezinzulu.

Yintoni ebangela i-nitrogen narcosis?

Iingcali aziqinisekanga malunga nesona sizathu se-nitrogen narcosis.

Xa uphefumla umoya oxineneyo ovela kwitanki leoksijini ngelixa uphantsi koxinzelelo oluninzi emanzini, yonyusa uxinzelelo lweoksijini kunye nenitrogen egazini lakho. Olu xinzelelo lwandayo luchaphazela inkqubo yakho yeemvakalelo. Kodwa akukho mntu uqinisekileyo malunga neendlela ezithile ezibangela ukuba oku kwenzeke.

Ngaba abanye abantu bathambekele ngakumbi kwi-nitrogen narcosis?

I-nitrogen narcosis inokuchaphazela nayiphi na i-divers-sea diver, kwaye uninzi lwamava ezinye zeempawu zayo ngaxa lithile.

Nangona kunjalo, unomngcipheko ophezulu wokuphuhlisa i-nitrogen narcosis ukuba:

• usele utywala ngaphambi kokuntywila
• unexhala
• batyhafile
• phuhlisa i-hypothermia ngaphambi okanye ngexesha lokuntywila

Ukuba ucwangcisa ukuntywila elwandle, qiniseka ukuba uphumle kakuhle, ukhululekile, kwaye unxibe ngokufanelekileyo ngaphambi kokuzama ukuntywila. Kulumkele ukusela utywala kwangoko.

Ifunyaniswa njani i-nitrogen narcosis?

I-nitrogen narcosis ihlala isenzeka embindini wolwandle olunzulu, ngenxa yoko kunqabile ukuba kufunyaniswe ukuba ngugqirha. Endaweni yokuba wena okanye iqabane lakho lokuntywila niya kuthi nizibone kuqala iimpawu. Qinisekisa ukuba abo bakungqongileyo ngexesha lokuntywila bayayazi imeko kunye nendlela yokuqonda iimpawu zayo, kubo nakwabanye.

Nje ukuba ufike kwisikhephe okanye emhlabeni, funa unyango olungxamisekileyo ukuba iimpawu zakho azihambi emva kwemizuzu embalwa.

Inyangwa njani i-nitrogen narcosis?

Olona nyango luphambili lwe-nitrogen narcosis kukuzifumana nje emanzini. Ukuba iimpawu zakho zithambile, ungahlala emanzini angenzulu kunye neqabane lakho lokuntywila okanye iqela ngelixa ulinde ukuba zicace. Nje ukuba iimpawu zakho zicinywe, ungaqhubeka nokuntywila kwakho kubunzulu obunzulu. Qiniseka nje ukuba awubuyeli kubunzulu apho uqale khona ukuba neempawu.

Ukuba iimpawu zakho azizisombululi wakufikelela emanzini angekho nzulu, kuyakufuneka uphelise ukuntywila kunye nentloko ngaphezulu.

Ukuntywila ngexesha elizayo, unokufuna umxube owahlukileyo weegesi kwitanki lakho leoksijini. Umzekelo, ukunciphisa ioksijini ngehydrogen okanye ihelium endaweni yenitrogen kunokunceda. Kodwa oku kunokunyusa umngcipheko wokuphuhlisa ezinye iimeko ezinxulumene nokudilika, ezinje ngokugula uxinzelelo.

Sebenza nogqirha wakho kunye nomqeqeshi onamava wokuntywila ukufumana ezinye iindlela zokuzama ukuntywila ngokulandelayo.

Ngaba ibangela naziphi na iingxaki?

I-nitrogen narcosis iqhelekile kwaye yexeshana, kodwa oko akuthethi ukuba ayinakuba neziphumo ezihlala zihleli. Abanye abahlukeneyo abahlakulela i-nitrogen narcosis baye baphazamiseka kakhulu ukuba bangadada emanzini amancinci. Kwezinye iimeko, ukuphambuka kungangena kwi-coma ngelixa liphantsi kwamanzi.

Ukuzama ukuzibuyisela kumphezulu kunokukhokelela kwiingxaki. Ukuba uvuka ngokukhawuleza, unokuhlakulela isifo sokudodobala, okusoloko kubizwa ngokuba kukugoba. Oku kubangela ukwehla ngokukhawuleza koxinzelelo. Ukugula okunganyanzelekanga kunokubangela iimpawu ezinzulu, kubandakanya amahlwili egazi kunye nokulimala kwezicubu.

Funa unyango olungxamisekileyo ukuba ufumana ezi mpawu zilandelayo emva kokubuyela kumphezulu wamanzi:

• ukudinwa
• ukungabi namdla wokutya
• intloko ebuhlungu
• Ukugula ngokubanzi
• intlungu, idibeneyo, okanye intlungu yomzimba
• ukudumba
• isiyezi
• iintlungu esifubeni
• ingxaki yokuphefumla
• umbono kabini
• ubunzima bokuthetha
• ubuthathaka bemisipha, ikakhulu kwelinye icala lomzimba wakho
• Iimpawu ezinjengomkhuhlane

Unokuwunciphisa umngcipheko wokuphuhlisa isifo sokudodobala ngo:

• ngokuthe chu ukusondela kumphezulu
• ukuntywila ngokulala kakuhle ebusuku
• ukusela amanzi amaninzi kwangaphambili
• ukunqanda ukuhamba komoya kungekudala emva kokuntywila
• Ukwahlula iidiving zakho, ubuncinci ngemini
• ukungachithi ixesha elininzi kubunzulu boxinzelelo oluphezulu
• unxibe i-wetsuit efanelekileyo emanzini abandayo

Kuya kufuneka ukhumbule ngakumbi ukunciphisa umngcipheko wokugula ngokunganyanzelekanga ukuba:

• yibane ntliziyo
• batyebe kakhulu
• badala

Qiniseka ukuba wena nawo wonke umntu ontywila naye niyayazi indlela yokuqonda iimpawu zokugula uxinezeleko kunye nendlela yokunciphisa umngcipheko wokukuhlakulela.

Yintoni imbonakalo?

Kwiimeko ezininzi, i-nitrogen narcosis iyacoca xa ufika emanzini asezantsi. Kodwa iimpawu ezinje ngokudideka kunye nokugweba okungafanelekanga kunokwenza ukuba kube nzima ukwenza oku. Ngokucwangcisa kwangaphambili kunye nokwazisa, ungaqhubeka nokudilika ngokukhuselekileyo kwaye unciphise umngcipheko we-nitrogen narcosis kunye neengxaki ezinokubakho.
