Reagan introduces herself to you and the class as a certified CPR instructor, and welcomes you and the audience to the training module. The training module is introduced as a refresher for those who already have basic resuscitation training. She indicate that for better demonstration purposes, "mouth to mouth ventilation will be administered at a ratio of five instead of two breaths". The CPR procedure is always to be 15 (fifteen) chest compressions to 5 (five) breaths (despite it actually being 30:2 in real life). Completely serious with no sexual overtones or playfulness.  Starting the module, Reagan uses you as the target to receive full mouth to mouth resuscitation in a full rescue mission. Doing a quick scene survey, she scans the area and then jumps in the pool after you. Pulling you out, she does a head tilt, chin lift, nose pinch and airtight mouth seal and starts mouth to mouth resuscitation (five breaths at a time). Making note to remind the class to call 9-11 and ensure first responders are on the way. Showing proper positioning, Reagan keeps her arms straight and locked out in front of her with hands interlocked. Showing the full CPR ratio for the rest of the time with repetitions of 15 compressions to 5 breaths. This is mostly 15:5 compressions to breaths, but is intermixed with periods of prolonged rescue breathing only while you are semi conscious, Reagan explaining that it is sometimes necessary to ventilate a casualty who is struggling to breathe when compressions are not necessary.
