Kind of a half-hearted CPR attempt.
She did it for, what, ten seconds?
CPR is one of the most unrealistic things portrayed on TV. If they're in a hospital they're shocking the person about every 5 seconds (only supposed to be done every 2 minutes). If they're elsewhere, it's done for maybe 10 seconds after which time they either spring back to life (very rare without a shock), or are declared dead (sometimes by a medical expert without even attempting CPR).
