The aim of this prospective, consecutive, cohort study was to investigate the biomechanical effects, if any, of the Blom low profile voice inner cannula and Passy-Muir one-way tracheotomy tube speaking valves on movement of the hyoid bone and larynx during swallowing. Ten adult patients (8 male, 2 female) with an age range of 61-89 years (mean 71 years) participated. Criteria for inclusion were ≥18 years of age, English speaking, and ability to tolerate both changing to a Blom tracheotomy tube and placement of a one-way tracheotomy tube speaking valve with a fully deflated tracheotomy tube cuff...

PURPOSE: Tracheostomy speaking valve use may increase airflow resistance and work of breathing. It remains unclear which valve offers the best performance characteristics. We compared the performance characteristics of the Shikani speaking valve (SSV; unidirectional-flow ball valve) with those of the Passy-Muir valve (PMV; bias-closed flapper valve). METHOD: Airflow resistance was measured for both the SSV and the PMV at 8 flow amplitudes and in 3 orientations (-15°, 0°, +20°) in the bias-open and bias-closed configurations...

OBJECTIVES/HYPOTHESIS: Alterations in swallowing can occur after tracheotomy and can result in varying degrees of aspiration. In tracheotomized adult patients, use of a Passy Muir Speaking Valve (PMV) has been shown to decrease laryngeal penetration and aspiration of foods and liquids. The objective of this study was to determine if the PMV has a similar effect on laryngeal penetration and aspiration in tracheotomized children. STUDY DESIGN: This is a prospective case-control study...

Dysphagia occurs in a significant number of individuals with spinal cord injury (SCI) presenting to acute care and inpatient rehabilitation. This prospective study has found dysphagia in nearly 40% of individuals with tetraplegia. Tracheostomy, mechanical ventilation, nasogastric tube, and age are significant risk factors. The detrimental complications of dysphagia in SCI can cause significant morbidity and delays in rehabilitation. Thus, early and accurate diagnosis of dysphagia is imperative to reduce the risk of developing life-threatening complications...

OBJECTIVES/HYPOTHESIS: Placement of a Passy-Muir speaking valve is considered best practice for infants and children with a tracheostomy. The Passy-Muir valve enables phonation by redirecting exhaled air via the glottis. Poor tolerance of the Passy-Muir valve is associated with excessive transtracheal pressures on exhalation due to upper airway obstruction. Drilling a small hole in the side of the Passy-Muir valve creates a pressure relief port to allow partial exhalation through the tracheostomy tube while enabling phonation...

OBJECTIVE: The aim of this study was to examine the relationship between cough peak flows (CPFs) before and after tracheostomy tube removal (decannulation) in patients with neuromuscular respiratory muscle weakness. DESIGN: For 26 patients with occluded tracheostomies (capped or Passy-Muir valve), spontaneous CPF (CPF(sp)), CPF after lung volume recruitment (CPF(LVR)), and CPF after lung volume recruitment and a manually assisted cough (CPF(LVR) + MAC) were measured before and after decannulation...

BACKGROUND: The objective of this work was to obtain a controlled subjective and objective in vivo clinical comparison of the Passy-Muir, Shiley, and Ball speaking valves. METHODS: Ten patients free of laryngeal pathology but dependent on tracheotomy for respiration were tested with each of the speaking valves. Olfaction was assessed for each patient using the University of Pennsylvania Smell Identification Test (UPSIT). Acoustic and perceptual analyses included subjective assessments, noninstrumental objective assessments (including maximum phonation time, and S:Z ratio), and instrumental objective assessments (including fundamental frequency:maximum phonation range, vocal intensity, perturbation, naturalness, and turbulence)...

Chimpanzee attacks can be vicious, mutilating, and disabling if not fatal. Stereotypically, the hands and face are targeted, and in male victims, genitalia are mutilated. The authors present a case highlighting the difficulties with early neurological assessment following such an attack. This 55-year-old woman was attacked by a 14-year-old chimpanzee. She suffered mutilation of both hands, severe midface bony, soft-tissue, and eye injuries, and scalp degloving. An emergency tracheotomy was performed at the scene, with an unclear duration of hypoxia...

PURPOSE: Many patients with respiratory failure related to neuromuscular disease receive chronic invasive ventilation through a tracheostomy. Improving quality of life, of which speech is an important component, is a major goal in these patients. We compared the effects on breathing and speech of low-level positive end-expiratory pressure (PEEP, 5 cmH(2)O) and of a Passy-Muir speaking valve (PMV) during assist-control ventilation. METHODS: We studied ten patients with neuromuscular disorders, between December 2008 and April 2009...

BACKGROUND: Little is known about the school experience of children with tracheostomy tubes. These children may represent a population that qualifies for special services in school. Understanding how tracheostomy affects school-aged children may provide information needed to develop programs that provide these children with invaluable experiences. OBJECTIVE: To understand what children with tracheostomies experience in school as it relates to tracheostomy care and how their condition affects academic achievement and social adjustment...

Pediatric tracheostomy dependence is associated with a variety of sequelae. Vocalization delay is commonplace and may result in long-term communication disability. Passy-Muir speaking valves are routinely used to allow such children to vocalize. Unfortunately, not all tracheostomy dependent children can tolerate the placement of a speaking valve. Elevated transtracheal pressures are often associated with failure. We describe a method of modifying a standard Passy-Muir valve to decrease transtracheal pressures and thus improve tolerance of the valve...

As the number of patients who are ventilator dependent increase, the tracheostomy has become an increasingly popular procedure. Inability to either communicate verbally or take food and liquids orally constitute the main distress symptom of patients, which can delay progress in treating the conditions of patients undergoing tracheostomies. Passy-Muir speaking valves (PMV) succeed in overcoming the abovementioned problems and clinical practice is gradually broadening. This article introduces the relevant underlying principles, indications, advantages, disadvantages and nursing principles of PMV...

In the first part of the article we described diagnostic methods aiming to resolve the individual underlying pathomechanism of chronic swallowing disorders (dysphagia). From these, we deducted different therapeutic measures that can be applied either alone or in combination. Weakening of the upper esophageal sphincter with botulinum toxin is reserved for patients with structural stenosis or a relative hyperfunction of the sphincter. It can be tried to use the "Passy-Muir Valve" for tracheostomized patients that aspirate...

Patients with chronic dysphagia are often in need of artificial nutrition; though being well balanced in terms of energy and vitamins, patients are at a high risk for the loss of resistance and body weight. Dysphagia also causes a severe drawback of the overall quality of life. This paper gives an overview of the present management of dysphagia from the point of view of otolaryngologists, head-neck-surgeons, phoniatricians, and medical speech-language-voice-pathologists. The physiology of swallowing and typical symptoms of dysphagia are first explained...

PURPOSE: We determined instances of aspiration in adults with tracheostomies and investigated the effect of the Passy-Muir tracheostomy speaking valve on occurrences of aspiration. METHODS: Adults with tracheostomies scheduled for videofluoroscopic swallowing examinations who met inclusion criteria were enrolled. According to study protocol, 6 presentations of thin liquids were recorded, 3 with and 3 without the Passy-Muir tracheostomy speaking valve. If a cuffed tube was present, the cuff was deflated fully for all presentations...

INTRODUCTION: Early vocalization and speech production remains a goal in children who require tracheotomy for airway obstruction or chronic ventilation. Although studies document the efficacy of the Passy-Muir valve (PMV) in adults, none have reviewed its efficacy in children. We performed this study to better understand the clinical complexity of its use in children. MATERIALS AND METHODS: Retrospective evaluation of 55 consecutive cases of children with tracheotomy using the PMV...
