The 24-year-old former medical student, who is currently in England for her county stint with Berkshire, had a day to remember recently when she put her medical training to practice.
Blackwell was playing a league match few days back at Shepparton Cricket Club when all the drama unfolded.
Inclement weather ensured players remain indoors. An 80-year-old club patron, John collapsed and people in the vicinity pressed for emergency first aid.
"Myself and another player, Louise, rushed over and immediately knew this man was in a great deal of trouble. With no breathing and absent pulse we had to commence CPR," Blackwell told the Cricket Australia official website cricket.com.au.
The Wagga Wagga (NSW) born batting all-rounder is no stranger to life in the medical world, she spent four years doubling her cricket training with medical classes and although had never been confronted with such a scenario in real life, she was confident in putting her training to practice.
"Fortunately I have gone through my fair share of training while studying medicine; Louise was on compressions while I was delivering mouth to mouth," she said.
"We continued CPR for nine minutes, and to be honest I thought we had lost him, but we just kept going until paramedics arrived and were ready with the defibrillator."
The 24-year-old Alex breathed a sigh of relief when she was told that the octogenarian cricket buff was on recovery path.
John"s son was very appreciative of what I and Louise did.
"It was such a great feeling to hear that John had managed to pull through and that Louise and I had managed to keep him going till help arrived," the relieved cricketer with medical background said.
