I'm assuming this is the basic first aid/cpr course, and if it is not so different than the canadian course, it should only last 2 or 3 afternoons. Something you could do in a weekend.
Have you heard anything about any further/specialty courses offered here in English, perhaps one to the tune of wilderness first aid? The basic course (again I'm basing my assumptions on a canadian red cross course) delivers the technique you'll need to know given the EMS arrival time, in a city, of between 15-30 minutes. Anything longer than that and you'll need to be doing more to save a victims life. ie- remote settings.
