The Olin EILOBI Breathing Techniques: Description and Initial Case Series of Novel Respiratory Retraining Strategies for Athletes with Exercise-Induced Laryngeal Obstruction
2018, Journal of VoiceCitation Excerpt :Within the domain of respiratory retraining, several specific techniques have been described with anecdotal success in relieving symptoms among patients. Approaches have included teaching patients to vocalize during exhalation, pant, yawn, open the posterior oropharynx, lower the base of the tongue, and perform “wide-open throat breathing” or pursed-lip breathing with trials during exercise.7,20–28 Some patients continue to struggle with exertional dyspnea after several respiratory retraining sessions despite adequate learning and compliance with demonstrated techniques.
Drug-Induced Paradoxical Vocal Fold Motion
2018, Journal of Allergy and Clinical Immunology: In PracticeCitation Excerpt :Commonly reported triggers include perfumes, odors, changes in humidity and/or temperature, exposure to chemicals, and strong emotions.17,18 Patients typically have multiple ED visits and/or intensive care unit (ICU) admissions, and some have a concomitant diagnosis of asthma or idiopathic allergic reactions.10,21-23 The presence of a tracheostomy scar or a history of intubation does not exclude a diagnosis of PVFM.6

2013, Immunology and Allergy Clinics of North AmericaCitation Excerpt :Importantly, organic causes of upper airway obstruction often serve as a fixed obstruction and yield blunting of both the inspiratory and expiratory loops, which should prompt a radiologic and endoscopic evaluation looking for a fixed obstructive process rather than for a functional disorder like VCD.4 In contrast to inspiratory VCD, asthma and expiratory VCD generally causes truncation or scooping of the expiratory loop on spirometry.51,69,70 One useful spirometric measure for assessing patients with VCD is the FEF50/FIF50 ratio, which is normally less than or equal to 1.
Diagnostic criteria for the classification of vocal cord dysfunction
2010, ChestCitation Excerpt :The first series of exertional VCD demonstrated some degree of expiratory closure.29 Several VCD case reports have demonstrated changes in the expiratory portion of the FVL.61,81,82 Early expiratory closure may be a compensatory physiologic mechanism in asthma.83,84
