A frightening lightning strike at Savin Hill Beach in Dorchester rendered a woman pulseless yesterday, but the heroic actions of a Boston Children's Hospital ICU nurse saved her life. Nurse Tracy Cronin, with assistance from her boyfriend, who is also an ER nurse, performed CPR on the unconscious woman, eventually reviving her before first responders arrived on the scene, according to the Boston Herald.

The 31-year-old woman was out walking her dog Bruce when the lightning struck her down, leaving her unconscious and with burns on her chest. Her pants were reportedly so scorched that the smell of burns permeated the air around her, as reported by CBS Boston. Cronin came along and, with her boyfriend's help, performed CPR on the woman for approximately 15 to 20 minutes before first responders arrived.

During an interview with CBS Boston, Cronin reflected on the rapid onset of the storm and the intensity of the lightning, stating that "it was the loudest lightning I ever heard."

Upon the arrival of first responders, they quickly shocked the woman several times, inserted a breathing tube, and hooked her up to an automatic CPR machine. She was then transported to Boston Medical Center, where she remains in critical condition according to Boston 25 News.

It is worth noting that lightning strikes are a rare occurrence. In fact, the odds of being struck by lightning in a given year are roughly one in a million, according to the Centers for Disease Control and Prevention via CBS Boston.

As for the dog Bruce, he was frightened by the lightning strike and ran off. The Massachusetts State Police are asking those who see the lost dog to contact the South Boston Barracks at 617-740-7710 according to Boston 25 News.
