EMT-B does not exist in any recognisable form the UK, the NHS or VASes don't put anyone with 110 hours of training on an ambulance, even PTS staff have more than that .
IHCD techs are not equivalent to US DoT EMT- I ( regardess of 85 or 99 ) , they have greater knowledge but a shorter laundry list of monkey-see, monkey-do skills .
EMT-I skill set is not facilitated by UK medicines legislation as there would be no legal means for a none Health Professional to adminster Parenteral Medications not included in the schedule 7 list - as the MHRA have stated they will not be supporting any more exemption requests after the Mountain rescue one .
The NHS service have no interest in recognising any qualification beyond the existing IHCD courses or HCPC registration as a Paramedic
the fact you think a 16 hour course (FPOS-I) is a post nominal demonstrates just how little you actually know aoburt Prew-hospital care preparation for practice .
