Volume targeted versus pressure support non-invasive ventilation in patients with super obesity and chronic respiratory failure: a randomised controlled trial. However, the impairment in the ventilatory response may improve with continuous positive airway pressure CPAP or nasal intermittent mandatory ventilation NIMV treatment, showing reversibility. Disagreements were resolved by consensus or by consulting the senior author FC.

Patwari P, Wolfe L. Article Navigation. In hypoventilatiom patients with OHS, CPAP therapy may be sufficient, but in those with hypercapnia and hypoxia the work of breathing has diminished to such an extent that the respiratory muscles weaken and are at risk of further fatigue. In other patients with severe restrictive defect secondary to morbid obesity, long-term bilevel PAP may be required.

Chest wall mechanics alone do not account for chronic hypercapnic respiratory failure, because continuous positive airway pressure CPAP —titrated to eliminate obstructive apneas—can normalize P CO 2 in some patients vide infra. Most patients with OHS snore, have witnessed apneas, choking episodes while sleeping, excessive daytime sleepiness and morning headaches, very similar to patients with OSA alone [ 23 ]. La Piana, S.

In addition, data may be missing, although all the patients were managed by the same medical staff, employing a homogeneous algorithm and, in consequence, very few patients were excluded because lack of fundamental data.

Yet, it is still plausible that an intrinsically diminished chemosensitivity editoor each individual contributes to CO 2 retention in OHS, a condition similar to that in chronic obstructive pulmonary disease [ 43 ].

Morbidity and Mortality The presence of OHS is associated with an increase in health care utilization, increased medical morbidity, and poorer health outcomes. Bariatric surgery is now widely accepted as a mainstay treatment in the management of obesity, especially for morbidly obese patients in whom more conservative approaches have failed or who have developed comorbidities.

Despite its prevalence, OHS has not been studied well, but there is abundant evidence that it is tightly linked with sleep-disordered breathing, most commonly obstructive sleep apnea. To the extent that OSA contributes to very gradual, incremental elevations of bicarbonate promoting chronic hypercapnia [ 22 ], continuous positive airway pressure CPAP during sleep may also be instrumental in reversing both the symptoms and acid base disturbances of OHS. In the first cycle, the interevent hyperpnea is sufficient to excrete the carbon dioxide accumulated during hypopnea.

Therefore, the objectives of this review are to examine the prevalence of OHS; review the current data on disease mechanisms, screening, and treatment; and discuss the optimal perioperative management of OHS.
