## What is Scuba Diving DMST?
Scuba diving DMST, also known as Decompression Management in Scuba Training, is a specialized training program that teaches divers how to safely manage decompression when diving. Decompression is the process of gradually ascending from depth to the surface to allow the body to adjust to the reduced pressure and avoid decompression sickness (DCS).
DCS is a serious diving injury that can occur when nitrogen bubbles form in the body’s tissues due to rapid ascent from depth. These bubbles can block blood vessels and cause pain, tissue damage, and even paralysis.
DMST training teaches divers how to calculate decompression stops, use decompression tables, and monitor their dive profiles to minimize the risk of DCS. It also covers emergency procedures for dealing with DCS and other diving emergencies.
DMST training is typically offered by scuba diving agencies such as PADI, SSI, and NAUI. It is recommended for divers who plan to dive deeper than 30 meters (100 feet) or for extended periods of time.
### Benefits of DMST Training
There are many benefits to taking a DMST training course, including:
Increased safety: DMST training teaches divers how to safely manage decompression, which can significantly reduce the risk of DCS.
Extended dive time: Divers who are trained in DMST can dive deeper and for longer periods of time than divers who are not trained in decompression management.
Improved dive planning: DMST training teaches divers how to plan dives that take into account decompression requirements, which can help to maximize bottom time and minimize the risk of DCS.
Greater confidence: Divers who are trained in DMST are more confident in their ability to dive safely and enjoy the underwater world.
### Prerequisites for DMST Training
To take a DMST training course, divers must typically meet the following prerequisites:
Be certified as a scuba diver with at least 20 logged dives
Be in good physical health and have no known medical conditions that would contraindicate diving
Be able to swim comfortably and be able to tread water for 10 minutes without assistance
Be able to perform basic scuba diving skills, such as mask clearing, regulator recovery, and buoyancy control
### What to Expect in a DMST Training Course
A DMST training course typically consists of both classroom and in-water sessions. Classroom sessions cover the following topics:
The physics of decompression
Decompression theory and models
Decompression tables and dive computers
Decompression planning
Emergency procedures for DCS
In-water sessions cover the following topics:
Decompression diving techniques
Decompression stop procedures
Emergency ascent procedures
DMST training courses typically take 2-3 days to complete.
### Conclusion
DMST training is an essential safety course for divers who plan to dive deeper than 30 meters (100 feet) or for extended periods of time. It teaches divers how to safely manage decompression and avoid the risk of DCS.
