Abstract
A method of removing exhaled material from a medical procedure field adjacent to a subject's nose and mouth. In some embodiments the method includes the steps of placing an isolation barrier at least partially surrounding the subject's nose and mouth to define the medical procedure field; controlling air flow into the medical procedure field with the isolation barrier; and evacuating air from the medical procedure field at an air evacuation rate greater than or equal to the subject's respiratory minute volume. The invention also provides a system for creating an isolated medical procedure field around a subject's nose and mouth.
