Cardiac cath meds-scared

I found out today what meds they will be using for my diagnostic cardiac cath on Friday. One is Midazolam, the other is fentany. I looked both of these up and it says that they can cause lower oxygen or respiratory problems. My oxygen already goes low when I am sleeping. I am really scared now. Has anyone had these meds with low o2??

I had to look up midazolam and that's the same as Versed. I can't stand drugs but I love Versed. Such a happy med. I've had Versed and fentanyl (for pain) during all 3 of my catheter ablations.

During the cath they will have the pulse oximeter clipped to your finger and will monitor your O2 levels the whole time. If they think you're going a bit low, they'll just give you some oxygen. I already have lung problems with asthma and they never had any problems with me during the ablations.

What does it feel like to be on these meds? They are doing a diagnostic cath and I am only 25, so you can imagine how scared I am. I never had meds like this.

It depends on how much they give you but it's referred to as conscious sedation. That means you're drowsy and may drift in and out of sleep but you're not so knocked out that they have to stick a tube down your throat or anything gross like that.

The fentanyl is just for any discomfort that a person might feel. With ablations they had to burn little spots inside my heart so the fentanyl came in handy. And yes, they did have to run catheters (4 of them actually) up into my heart . It's not bad at all. I didn't feel a thing. It was kind of interesting to watch them wiggle around on the little TV screen they had near by. But then I zonked out.
