“…Only 4 case reports commented on peak airway pressures on mechanical ventilation; 2 noted normal peak airway pressures (no values given), one was reported at 22 cm H 2 O and another at 25 cm H 2 O. 30,37,75,82 In our experience, resolution of wheezing and/or stridor postintubation with normal airway pressures should prompt laryngoscopic evaluation for the presence of VCD.…”

“…147 This has not been substantiated in any studies, and hypoxemia has been reported in association with 10 cases of VCD. 12,14,24,46,82,83,117 Appleblatt and Baker documented mild hypoxemia during an acute VCD episode that resolved when the patient was asymptomatic. Three of 4 VCD patients with concomitant asthma reported by Nolan et al were also noted to have hypoxemia during attacks.…”

Vocal cord dysfunction, a syndrome of paradoxical inspiratory closure of the vocal cords, is becoming more frequently recognized and diagnosed recently since its initial modern description 30 years ago. Initially described as single case reports, the first case series in 1983 helped to clarify the typical patient and findings of vocal cord dysfunction. Recent investigations have elucidated specific etiologies such as gastroesophageal reflux, exercise, and irritants as causative factors in addition to the numerous associated psychologic factors. Speech therapy and psychotherapy have been used extensively with vocal cord dysfunction patients, but the optimal treatment has yet to be prospectively studied. This manuscript provides a comprehensive review of the reported causative factors and treatments for vocal cord dysfunction.

Paradoxical vocal cord motion disorder (PVCM), also called vocal cord dysfunction, is an important differential diagnosis for asthma. The disorder is often misdiagnosed as asthma leading to unnecessary drug use, very high medical utilisation and occasionally tracheal intubation or tracheostomy. Laryngoscopy is the gold standard for diagnosis of PVCM. Speech therapy and psychotherapy are considered the cornerstone of management of this disorder. The aim of this article is to increase the awareness of PVCM among doctors, highlighting the main characteristics that distinguish it from asthma and discuss the recent medical achievements and the possible future perspectives related to this disorder.

“…Inspiratory stridor is a condition characterised by high pitched inspiratory noise that is often mistaken for the wheeze of asthma 2 – 4. The presence of inspiratory stridor is associated with vocal cord dysfunction that can be diagnosed by laryngoscopy.…”

Inspiratory muscle training: a simple cost-effective treatment for inspiratory stridor: Table 1

This case study describes the support given to a British elite athlete in the build up to the 2004 Athens Olympic Games. The athlete had complained of breathing symptoms during high intensity training that led to a reduction in performance and premature cessation of training. Following a negative eucapnic voluntary hyperpnoea challenge and observation during high intensity exercise, the athlete was diagnosed with inspiratory stridor. Inspiratory muscle training (IMT) was implemented to attenuate the inspiratory stridor. Following an 11-week IMT programme, the athlete had a 31% increase in mouth inspiratory pressure and a reduction in recovery between high intensity sprints. The athlete reported a precipitous fall in symptoms and was able to complete high intensity training without symptoms. This case shows that IMT is a suitable cost-effective intervention for athletes who present with inspiratory stridor.
