What is a DSMB in scuba?

A delayed surface marker buoy (DSMB), decompression buoy, or deco buoy is an inflatable buoy which can be deployed while the diver is submerged and generally only towards the end of the dive.

When should I deploy Dsmb?

Most recreational divers deploy it from their safety stop. We recommend you deploy your SMB before you start your ascent. This means you’re doing it from a deeper point which makes it easier to control your buoyancy, plus you don’t have to get as much air into the SMB.

What does a yellow DSMB mean?

YELLOW. Yellow SMBs are for Emergencies in some circles but simple Location Markers elsewhere, you will often see EMERGENCY written down the length of a yellow dSMB and are used by advanced divers that can’t ascend to the surface but need help or equipment from the surface without surfacing.

Is a DSMB required?

As a general guideline, DSMBs are needed for clinical trials of diseases with high mortality or morbidity, for clinical trials involving high risks, and for large, multicenter clinical trials.

How do I choose a DSMB?

dSMBs should be bright in colour (usually orange), and large enough when inflated so that they can be clearly seen from the surface by motor vessels even in high swells. Usually they have the caption ‘diver below’ or something similar written down the side.

What color is DSMB?

Standard surface markers should be red or orange. You should only use a yellow DSMB in an emergency.

What does DSMB stand for?

Data and Safety Monitoring Board. An impartial group that oversees a clinical trial and reviews the results to see if they are acceptable. This group determines if the trial should be changed or closed. Also called Data and Safety Monitoring Board.

Why is a DSMB important?

The purpose of the DSMB is to provide oversight and monitoring of the conduct of clinical trials to ensure the safety of participants and the validity and integrity of study data.

How do you use DSMB scuba?

Where do I carry DSMB?

Once your DSMB is setup, store it in a BCD pocket, or simply clip it to your BCD.

What is SMB used for in diving?

A surface marker buoy (SMB) is signaling equipment used by divers underwater. These are large, tube-shaped devices that can be inflated underwater and sent up to the surface to mark the diver’s location and alert anyone on the surface that there are divers below. They are usually brightly colored.

What are the 3 types of diving?

Each of the dive groups is represented by a number in competition: Forward Dive – 1. Backward Dive – 2. Reverse Dive – 3.

How do you inflate a SMB underwater?

An SMB with a tube that’s open on the bottom can be inflated by adding air from the second-stage regulator (or octopus regulator) into the tube. Simply invert the regulator beneath the open tube and depress the regulator purge button briefly.

Which is an advantage of SMB?

SMB allows for a great increase in handling number of users, and giving them file access and operational control for every server used.

Should I use AFP or SMB?

Apple Filing Protocol (AFP)

OS X supports SMB largely because there are many environments in which only Microsoft and other SMB servers are available on a network. However, SMB is proprietary to Microsoft and was designed specifically for Windows clients whereas AFP was designed by Apple for Mac clients.

Is SMB a security risk?

Leaving an SMB service open to the public can give attackers the ability to access data on your clients’ internal network, and increases their risk of a ransomware attack or other exploit.

Why is SMB so vulnerable?

Why is it a risk? Version 1.0 of SMB contains a bug that can be used to take over control of a remote computer. The US National Security Agency (NSA) developed an exploit (called “EternalBlue”) for this vulnerability which was subsequently leaked.
