All that vomits is not the flu: identifying and managing nausea and vomiting.

The causes of N&V can be medications; abdominal, infectious, endocrine and CNS illnesses; environmental and toxicological conditions and ischemia. There are several interventions that EMS providers can use to minimize patient's N&V, including oxygen and medications such as promethazine (Phenergan), ondansetron (Zofran) and metoclopramide (Reglan). Most important, remember that there are many other potentially deadly causes of N&V apart from the flu.
