On the morning of May 8th, nurse Lisa Watson had just arrived at her hospital,

when pretty quickly it was clear that something wasn't right.

None of the patients could call in their breakfast trays.

So that was like the big first key that things were awry.

Lisa is an ICU nurse at Via Christie Ascension St. Francis Medical Center in Wichita, Kansas.

It progressed throughout the day. I wasn't there that whole day, but it progressed

throughout the day that charting wasn't working, code blue buttons weren't working,

any kind of way to alert somebody that there was a problem in the system wasn't working.

By the way, those code blue buttons that weren't working.

They're used to alert floor staff when an adult is having a critical medical emergency,

often cardiac arrest.

So whatever was going on, it was a big deal.

Lisa's Hospital is just one of the roughly 140 hospitals across 19 states and Washington DC that are operated

by the Ascension Healthcare Network.

The problem though wasn't just isolated to Wichita. Within hours many hospitals across one of America's

largest health care networks reported similar technological paralysis.

Ascension had been hacked.
