Many people suffer from ear problems during and after diving. Technical rebreather diver and underwater photographer Dr. Michael Rothschild is an ear, nose and throat specialist in New York City. In this series, he walks us through some of the common causes of dive-related ear problems, and how to treat and prevent them.

Thermal stress

A rapid chilling of superficial skeletal muscles (conductive cooling) creates a crippling weakening.

Thermal issues affect the comfort, performance and decompression stress experienced by divers. The impact varies with the timing, direction and magnitude of the thermal stress. Thermal protection can be provided by a variety of passive and active systems. Active systems should be used with particular care since they can markedly alter inert gas exchange and decompression risk.

DAN Encourages Safe Diving During Florida Lobster Mini Season

While it’s a fun, challenging and tasty experience for most, more than 20 divers have lost their lives during mini season in the last decade.

Through analysis of these tragic deaths, researchers at Divers Alert Network (DAN) have identified the most relevant contributing factors and most important safety practices for divers participating in the annual event.

These tips probably won’t surprise you, but sometimes the most basic precautions are the most likely to save a life.

DAN Offers Regional Emergency Hotlines in Latin America, the Caribbean, and Asia Pacific

Earlier this year DAN launched a dedicated Spanish-language emergency hotline. Now, Spanish-speaking divers can call +52-557-100-0540 to talk to Spanish-speaking medical professionals.

Although DAN has had Spanish-speaking medical staff for many years, the Spanish-language DAN Emergency Hotline means that now the person who answers the call will speak the caller’s own language.

This new hotline follows the Portuguese-language DAN Emergency Hotline (+55-11-3042-1157) that was launched in 2015 for divers in Brazil.

DAN Adds Severe Infectious Disease and Quarantine Coverage to Its Enhanced Membership

In February of this year DAN launched Enhanced Membership, which includes a higher benefit limit for medical transportation (up to $500,000), a continuing subscription to the print edition of Alert Diver magazine, and expanded travel assistance benefits, including search and rescue coverage and global security evacuation coverage.

Nosebleeds in Scuba Diving

Well-trained divers all know that they need to equalize their ears and sinuses as they descend. Usually, this is an easy process. However, there are some medical conditions that can make this more difficult. Technical rebreather diver and underwater photographer Dr. Michael Rothschild is a pediatric ear, nose and throat specialist in New York.

DAN Asks Divers to Donate in Support of Dive Safety

When you give to DAN, you support the DAN Emergency Hotline, ensuring it stays available 24/7 to assist divers everywhere. Since it went live in 1981, the hotline has helped tens of thousands of divers in times of need.

With many people returning to the water this summer after prolonged periods away, continued operation of this essential emergency service is more important now than ever before.
