I would have called an ambulance because they have sirens to get through traffic and go fast, and can start treatment as soon as they arrive, plus you can give emergency aid yourself until they arrive, instead of driving.
However, I acknowledge that my local paramedics are closer than my nearest hospital, and traffic is a greater factor than distance in Los Angeles. It might pan out differently on empty roads in the middle of nowhere.
I also know from my spouse’s several life-and-death medical crises that it’s hard to stay calm. Which argues against driving but explains the choice. I’ve run into a Code Blue and taken over, because I knew my spouse’s very specific needs were being missed. I would never do anything like that normally, but I did bring him back, so yeah, you do what you need to do.
I’m glad your wife is okay, and you didn’t crash into anyone.
