1. PRAVILO RONJENJA
NIKAD
NE
RONI
SAM !!!
Dekompresijska bolest
 Uzrokovana naglim smanjenjem pritiska
 Rizični faktori: - starija životna dob
- slabija tjelesna sprema
- višak masnog tkiva
- dehidracija
 Simptomi: - bol u zglobovima
- utrnulost tijela
- bol trupa
 Ukoliko se pritisak naglo oslobodi, dušik
se vraća u plinovito stanje brzinom koja je
prevelika da bi izašao iz tijela na normalan
način. Kao posljedica toga se po cijelom
tijelu formiraju mjehurići dušika, koji
uzrokuju bolest koju su ronioci do tada
povezivali s kostoboljom.
Dušikova narkoza
 Promjena svijesti – slična trovanju alkoholom
 Nastaje zbog udisanja dušika pod tlakom
 Simptomi ovise o dubini
 10 - 30 metara – blaga euforija, usporen tok misli
 30 - 50 metara – smijeh, pretjerano samopouzdanje,
usporene reakcije na vizualne i auditivne podražaje
 50 - 70 metara – zbunjenost, halucinacije
 70 - 90 metara – smanjena koncentracija, gubitak
pamćenja
 90+ metara – gubitak pojma o vremenu,
nesvjestica, smrt
Trovanje kisikom
 Rezultat udisanja kisika pri povišenom tlaku
 Simptomi: - drhtanje usnica
- uspavanost
- mučnina
- istraživanje trovanja
kisikom provedeno
u Ujedinjenom Kraljevstvu
 Toksično djelovanje pojavljuje se u dva oblika: Plućni oblik i
nervni oblik
 Ne predstavlja problem u rekreativnom ronjenju
 Može se sresti pri ronjenju zrakom s aparatom otvorenom kruga
na velikim dubinama
 Osobito je izražena opasnost kod ronjenja aparatima zatvorenog
kruga
Prevencija
 Izbjegavati duboka ronjenja
 Obavezna kontrola smjese prije ronjenja
 Dobra kontrola plovnosti
Liječenje
 Smanjenje pO2 simptomi ubrzo prestaju
 Neophodno je izroniti i prijeći na udisanje zraka
Opasnosti prilikom zakazivanja opreme
 Zakazivanje rebreathera
 Gubitak zraka u boci
 Propuštanje suhog odijela
Hvala na pažnji!
