I attended and paid for a CPR Class to renew my expired CPR card for my next job. I was one of 8 people who all passed the class but me. I did pass the written part on the second try getting 16/20. I, apparently, did not pass the skills part with the mannequins. It was a very upsetting day by 3:30 pm the class was ending, and i had thought i passed the class. The instructor asked me and another women to stay after to repeat performing on the mannequins for the infant and adult CPR, and choking infant. By this time, i was completely tired from being there for over 6 hours with a 15-20 minute break. I felt my blood pressure going up and stated i needed to step out of the room, where i went into the bathroom to call my employer to say i did not think i was going to pass the class, and i did not know what to do. I came back in the classroom, the instructor was still there, and told me she wanted to help me, and that i needed to repeat the CPR compressions again on the adult and child. The mannequin did not make the clicking sound every time, but i did manage to get 25/30 repetitions where it did click and the forehead and face lit up. I was then told that i was not going to pass by the instructor cause she did not feel comfortable passing me. I left the building and called the American Red Cross 1-800 number to ask if i could get my $89.00 back which they said No, if you did not pass the class, you could not get your money back, and you also could not retake the class with a different instructor for free. I feel i was singled out, and not passed for whatever reason, when others in the class were performing much worse on the mannequins than i was. I am not done with my fight to get my $89.00 refunded to me, i feel i was treated badly and unfairly by the instructor. I have 20 plus years in the medical field and was only taking the class to renew my expired certificate. This happened Oct. 31st, 2018 in Michigan. I was and still am appalled at what happened to me there.
