Abstract
A respiratory monitor apparatus comprises, in combination, a flexible mask fabricated from a stretchable fabric, such as spandex, that is designed to support a pneumotach flow measuring instrument in a way that does not require the instrument to be placed in the wearer's mouth, yet still remaining in fluid communication with the wearer's mouth and with little or no dead-space or leakage between the mask member and the wearer's face.
