Direct her to the restroom. This is the easiest way to assist a vomiting co-ed without getting directly involved in the process. If a person has the flu or is too weak to walk, you can lend her a hand in getting to the bathroom. Be prepared to dodge if she starts to vomit before she get there.
Get a bucket or trashcan to catch vomit. Many co-eds don't know they're going to start vomiting until it happens. If she does realize that she's going to puke, she may not have time to reach the bathroom and she may not know where the bathroom is. Getting her a bucket or trashcan as quickly as possible saves on the amount of time spent cleaning up.
Hold her hair so it doesn't fall into the puke. When a co-ed vomits, she may not even think about her hair. Getting vomit out of hair can be time consuming and disgusting.
Call for assistance if necessary. If a co-ed is unconscious and starts vomiting, you need to get her on her side so she doesn't choke on the vomit. Hold her head to keep it from falling back. If it looks like she's vomiting coffee grounds, she may be vomiting blood. You should call 911 or assist the co-ed in getting medical attention. If the vomit obstructs the airway you may need to perform CPR and call 911.
Bring her Pedialite. If a co-ed is vomiting because of illness, you can assist her by helping her stay hydrated. You can bring her chicken noodle soup or other clear liquids she likes to help her accomplish this.
