The way to save a person is to get them anti-venom as soon as possible. Time is very important so don't waste precious time trying to hunt down the snake. After the victim has been cared for, if you can't visually identify the snake species, you can try to capture the snake. Just make sure you don't get bitten in the process. Capturing the snake can aid in treatment but isn't always necessary.
Visual identification is just as good as bringing in the actual snake.
Before venturing out, make sure you know which snakes are native to the region and what they look like, so in the event of a bite, you'll be able to identify the offending snake. Inc.
