He said the Edmonton native is undergoing tests at the UCI Irvine Medical Centre in Anaheim, Calif.
Armstrong added Bouwmeester needed a defibrillator to revive him Tuesday. The 36-year-old Bouwmeester will be monitored by a team of specialists at the hospital until he is cleared to return to St. Louis.
Thankfully, the Blues players who witnessed Bouwmeester go down quickly called for medical attention and the Ducks medical team was able to get to him immediately.
Bouwmeester collapsed on the bench during the first period of the Blues' game at Anaheim and was taken to hospital. The game was postponed.
Blues President and General Manager Doug Armstrong addressed the media for the first time since the incident on Wednesday in Las Vegas. It felt like it was an eternity for us. "We're very lucky to have each other".
"It's going to be hard (to play Thursday), but we talked to Jay and he's in good spirits", Pietrangelo said.
Armstrong also confirmed that Jay's father was at the game as part of the traditional Father's Trip, where players are joined by their dads during a roadtrip. "But we talked to Jay, and he's in good spirits and when you see how he's doing it certainly makes us feel a lot better", Pietrangelo said.
The Blues in April signed the veteran defenseman to a $3.25 million, one-year deal for this season.
Bouwmeester is among only 29 players who has completed the career hockey hat trick of winning the Stanley Cup, an Olympic gold medal (with Canada in 2014 at Sochi) and a world championship (in 2003 and 2004).
