DAN INTRODUCED THE FIRST standardized emergency oxygen course for divers as lay providers in 1991. More people trained in oxygen delivery means that providers in dive locations worldwide need to have emergency oxygen units available. Obtaining oxygen refills, however, is an ongoing problem …
Divers Alert Network (DAN) mengelola jaringan ruang rekompresi global, yang terdiri atas basis data semua ruang hiperbarik yang memiliki kemampuan dan kemauan untuk merawat penyelam yang cedera.
Ketidaksesuaian antara katup dan silinder baru-baru ini mengakibatkan hasil yang mematikan di Eropa. Masalah ini dapat dicegah dengan pelatihan formal, pelatihan khusus fungsi dan pemahaman dasar tentang katup tangki scuba dan ulir silinder.
TIGA GAS yang umumnya digunakan dalam penyelaman rekreasi dan teknis adalah oksigen, nitrogen, dan helium. Nitrogen adalah yang paling melimpah dan biasanya merupakan gas standar, tetapi tampaknya tidak ada yang peduli dengan kemurniannya, meskipun Asosiasi Gas Terkompresi (CGA) A.S. menyediakan tingkat kemurnian, atau tingkatan, untuk berbagai aplikasi.
AFTER THE INITAL SCARE AND LOCKDOWNS FROM COVID-19, divers soon started to explore ways to safely get back into the water. Disinfection has always been a consideration in diving, but we needed new standards to allay fears of uncontrolled transmission of infectious diseases.
