Good Samaritan Health Professionals Act of 2011 - Amends the Public Health Service Act to provide that a health care professional shall not be liable under federal or state law for harm caused by any act or omission if: (1) the professional is serving as a volunteer for purposes of responding to a disaster; and (2) the act or omission occurs during the period of the disaster, in the professional's capacity as such a volunteer, and in a good faith belief that the individual being treated is in need of health care services.
Makes exceptions where: (1) the harm was caused by an act or omission constituting willful or criminal misconduct, gross negligence, reckless misconduct, or a conscious flagrant indifference to the rights or safety of the individual harmed; or (2) the professional rendered the health care services under the influence of intoxicating alcohol or an intoxicating drug.
