Modalities of ventilation in obesity.

Obesity is nowadays the most frequently found health risk in the USA, where more than 1 in 3 adults have a weight > or = 20% over the ideal value. Obese patients are more prone to developing sleep apnoea syndrome and obesity hypoventilation syndrome as well as more frequent postoperative complications. Thus, acute and chronic respiratory failure episodes represent current presentations in clinical practice where noninvasive ventilation is very efficient and must be guided by polysomnographic data in order to decide on long-term respiratory treatment to avoid recurrence of acute on chronic decompensation.

[The therapeutic considerations in the "overlap syndrome"]. / Consideratii terapeutice în "overlap syndrome".

The authors describe two cases of "overlap syndrome", emphasizing the difficulties of detecting, diagnosing and treating these cases. This paper allows us to review the medical works, trying to find out some answers to the therapeutical problems faced in these two cases.

[Initial experiments with controlled assisted ventilation by nasal mask in exacerbated chronic respiratory failure in chronic obstructive bronchopneumopathies]. / Primele experimente de ventilatie asistata controlata pe masca nazala la insuficientele respiratorii cronice acutizate din bronhopneumopatiile cronice obstructive.

The authors are presenting the first cases in Romania in which volumetric ventilators Monnal D type were used for external ventilatory assistance on nasal mask of the chronic obstructive pulmonary diseases in exacerbation. The paper reviews the problems issued during the use of ventilators in 5 chronic patients, with numerous previous admittances in our clinic, as well as the latest news in the field of modern therapy of COPD.
