How to carry out a measurement?
Carrying out a measurement
Once the dive has been made, the diver performs four measurements of 20 seconds each with the O’Dive connected sensor.
These measurements are carried outin two series: two measurements thirty minutes*, then two more measurements one hour after the dive.
*For dives with helium as the main inert gas, we recommend to perform the first series of measurements as soon as possible after surfacing.
The sensor positioned under the clavicle works with ultrasound signals transmitted to the smartphone via Wi-Fi. In airplane mode, the signals are momentarily saved. These signals will be transmitted to Azoth Systems’ server to be analysed as soon as the smartphone is connected again to a Wi-Fi or a cellular network.
After the measurements are taken, the diver fills in the dive parameters.
Results and simulations
Approximately 15 minutes after the signals are synchronized, O’Dive is providing the diver with a graph assessing his decompression. This graph specifies the procedure’s quality by locating it in one of the three zones: optimal, standard and non-optimal.
This result is expressed in comparison with a reference population coming from Azoth Systems’ database.
It is taking into account:
- The dive parameters
- The respired gases
- The resurfacing duration
- The quantity of circulating microbubbles detected in the diver’s venous system
Carry out a measurement
This way, the diver can evaluate in full autonomy the adequation of his decompression procedures with his own person and diving practice.
A personal model calibrated with the microbubbles’ detection and the registered dive parameters will get refined dive after dive.
This model will allow the diver to visualize through a simulator the benefit of several options (depending on the dive and the app) on his practice: longer decompression stops; oxygen stops; use of nitrox; modification of the Gradient Factors; diluent change…
