Passy-Muir PMV 005 Mode D'emploi page 4

The PMVs are light weight, one-way positive closure "no leak" valves that attach to the universal
15mm hub of adult, pediatric and neonatal tracheostomy tubes including the following: fenestrated,
non-fenestrated, cuffless, metal, and air-filled cuffed (with cuff completely deflated). Unlike open
position one-way speaking valves, the positive closure "no leak" PMVs maintain a bias closed
position except during inspiration. When the patient inhales, the PMV opens allowing air to enter
the tracheostomy tube and the lungs. At the end of inspiration the PMV closes and remains
closed throughout exhalation, without leakage. During exhalation, air is redirected around the
tracheostomy tube and up through the larynx and pharynx, enabling speech as the air passes
through the vocal cords and through the oral and nasal cavities.
The patented positive closure "no leak" design creates a column of air within the tracheostomy
tube that inhibits secretions from entering the tube and occluding the PMV. The bias closed position
of the PMV restores the patient to a more normal closed respiratory system. This results in the
restoration of positive subglottic pressure that facilitates a better swallow, may reduce aspiration
and facilitates a stronger, more effective cough that allows the patient to expectorate secretions
orally.
The PMVs are intended for use by both short-term and long-term adult, pediatric and neonatal
tracheostomized and/or ventilator dependent patients.
All Other Speaking Valves
Open Position Speaking Valves Have Air
Leak During Exhalation And Do Not
Provide A Closed Respiratory System
BENEFITS
The PMVs were developed to allow tracheostomized and ventilator dependent patients to
speak more normally. However, research has validated additional significant benefits with
use of the PMV:
• Positive Closure "No Leak" Design
Restores a Closed Respiratory System
• Improves Speech Production
• Improves Swallowing and May
Reduce Aspiration
• Facilitates Secretion Management
• Positive Closure "No Leak" Design: Restores a more normal closed respiratory system
which allows the patient to create positive airway pressure without the need for manual
occlusion of the tracheostomy tube.
• Speech: Tracheostomized and ventilator dependent patients can produce clearer speech
with more normal phrasing, better vocal quality and increased volume. Allows for normal
development of speech and language in children.
• Swallowing: Use of the PMV can improve the safety and efficiency of swallowing and may
reduce aspiration. Positive closure restores the patient to a more normal closed system
which facilitates increased pharyngeal/laryngeal sensation and restores positive subglottic
air pressure.
PMV Positive Closure "No Leak" Design
(1) PMVs Close Completely At End Of Inhalation With No Air Leak, Thereby Providing
A Closed Respiratory System And More Normal Breathing Pattern. (2) Positive Closure
"No Leak" Design Maintains A Column Of Air In Tracheostomy Tube Redirecting Airflow
And Secretions Up The Trachea (Airway) And Out Of The Mouth And/Or Nose.
