Hello @bethv

Welcome to Mayo Connect. I appreciate your post regarding your dad. I can understand your concern if he is unresponsive for as long as two hours. Perhaps some of our other members will respond to your question.

How long has your dad been having these episodes? If this is a new symptom? If so, has it been addressed with your dad's doctor?

I would also like to direct you to our Caregiver's discussion group, https://connect.mayoclinic.org/group/caregivers/. We have several members who are caregivers for aging parents and maybe someone can help answer your question. I will tag, @IndianaScott as well as @debbraw to join you in this conversation.
