Aside from having enough time to do this job, your advocate also needs to have the right temperament for it. You'll need to work together well. Be careful about tapping the most convenient person if that person clearly is not up for the job; just as you wouldn't deputize the first cousin you meet in the family reunion buffet line, don't automatically pick your spouse just because he or she is nearby, especially if your spouse also happens to be terrified of blood or is the most disorganized person you know.
Someone who's extremely stressed and anguished by needle sticks or your health challenge might make a poor advocate because you need someone who's going to stay objective. Find an advocate who will stay cool and clear-minded in a crisis.
