After taking dad out the swimming pool when he was feeling dizzy is anything else that i can do to help my dad?

See his doctor: If your dad is feeling dizzy you should find out why. It may be as simple as he needs to drink more water. or he might have labyrinthitis; or it may be something more serious, like heart failure or some strange heart rhythm. Whatever the cause, have him discuss his symptoms with his doctor.

Yes: If he is still dizzy then I recommend that you have him evaluated for heart issues or even small stroke. Good set of blood work and blood pressure, neurological evaluation important too.
