Passy-Muir™ Tracheostomy & Ventilator Swallowing and Speaking Valve
PMV™ 005 (White)

The Passy-Muir PMV 005 (White) (15mm I.D. / 23mm O.D.) is the original PMV. While it is more commonly used by non-ventilator dependent persons, it can also be used in-line with mechanical ventilators in conjunction with non-disposable, flexible rubber tubing.
