a better understanding of the physiological effects
of breath hold diving.
Other applications of this device are ECG, depth
and temperature recording during SCUBA dives.
5 FUTURE WORK
4 more prototypes will be fabricated to be then
deployed during the AIDA freediving world
championship in October 2007 in Sharm el Sheikh.
An enhanced second version of this prototype is
planned to address SCUBA diving applications. It
will be expanded with the following sensors:
breathing frequency, water temperature, skin
temperature and skin conductivity.
Software will be developed to allow an
automatic measurement of the PQ-interval. This will
be based on triggering on the QRS complex and then
calculating the time to the beginning of the P wave.
