A Obstructive sleep apnea (OSA) is a chronic, progressive, and potentially life-threatening disorder that can be effectively treated with surgery. It is also a condition that orthodontists see in their offices every day; thus, they are ideally suited to diagnose and treat it. OSA is related to an anatomic obstruction of the upper airway; surgical correction of the obstruction is effective and d...

Obstructive sleep apnea (OSA) and atrial fibrillation (AF) are associated with increased morbidity mortality. OSA AF share multiple risk factors, including hypertension, cardiovascular disorders, congestive heart failure, metabolic syndrome. Although the two conditions likely to have a bidirectional association, recent studies suggested that contributes development of through direct mechanical ...

BACKGROUND There is evidence to suggest that chronic continuous positive airway pressure (CPAP) therapy may produce reversible changes in upper airway morphology and function in patients with sleep apnoea/hypopnoea. This study was designed to examine the effect of chronic CPAP therapy on upper airway calibre. METHODS Twenty four men with the sleep apnoea/hypopnoea syndrome (mean (SE) apnoea/h...

Continuous positive airway pressure (CPAP) is a safe therapy for the management of obstructive sleep apnea (OSA). Complications such as sinus infection, bronchitis, ear pain, nasal congestion, and dryness of mucous membranes secondary to CPAP use have been reported. To follow, we describe a rare case of alternobaric vertigo secondary to CPAP therapy. To date, there has been only one reported ca...

Asthma is characterised by airway hyperreactivity, which is primarily treated with β-adrenergic bronchodilators and anti-inflammatory agents. However, mechanical strain during breathing is an important modulator of airway responsiveness and we have previously demonstrated in animal models that continuous positive airway pressure (CPAP) resulted in lower in vivo airway reactivity. We now evaluat...

livery of mechanical ventilation to patients with respiratory failure without the requirement of an artificial airway. The key change that led to the recent increase in the use of this technique occurred in the early 1980s with the introduction of the nasal continuous positive airway pressure mask for the treatment of obstructive sleep apnea. Studies published in the 1990s that evaluated the ef...

OBJECTIVE Continuous positive airway pressure (CPAP) is considered an effective nonpharmacologic method of treating patients with severe acute cardiogenic pulmonary edema. However, we hypothesized that bilevel noninvasive positive-pressure ventilation (NPPV), which combines both inspiratory pressure support and positive expiratory pressure, would unload the respiratory muscles and improve cardi...

The patient with acute heart failure may present with acute cardiogenic pulmonary edema (ACPE), a condition accompanied by severe respiratory distress, with crackles over the lung and orthopnea, and an O2 saturation usually < 90% on room air, prior to treatment. Non-invasive ventilation is the delivery of assisted ventilation without the need for endotracheal intubation and an invasive artifici...

OBJECTIVES Compliance with continuous positive airway pressure (CPAP) treatment remains a primary concern for improving treatment outcomes of obstructive sleep apnea. There are few studies that have considered the role of upper airway anatomy on the compliance with CPAP. We hypothesized that upper airway anatomy would influence the compliance with CPAP. METHODS One hundred out of 161 consecut...
