1. A helmet comprising:
- a frame operatively adapted to surround at least a portion of a person'"'"'s head;
a transparent face shield attached to the frame and positioned along a front side of said helmet;
an air channel having at least one air inlet and an air outlet consisting of a single air outlet, said single air outlet being positioned so as to provide air to a space bound by an inner surface of the transparent face shield;
a fan in fluid communication with the air channel, said fan being operatively adapted to move air through said air channel;
a battery pack attached to the frame and positioned above a lower edge of the transparent face shield and along opposite sides of the air channel, said battery pack being operatively adapted to supply electrical power to the fan; and
a hood surrounding the transparent face shield and extending over and downward from the frame.

Abstract
The present invention is directed to a helmet suitable for use in an operating room setting, an emergency room setting, a hospital setting, or a lab. The helmet of the present invention provides one or more of the following features: (i) superior barrier protection to a surgeon (or other operating room personnel) during a surgical procedure, (ii) a desired degree of air flow through the helmet so as to minimize the potential for carbon dioxide buildup within the helmet, and (iii) an integrated battery pack positioned within the helmet.
