We investigated the effect on daytime respiratory function and quality of sleep, of providing adequate ventilation either by intermittent positive pressure ventilation (IPPV) or by continuous positive airways pressure (CPAP) both administered through a nose mask in a group of seven patients with severe thoracic kyphoscoliosis. All night control sleep studies were performed with and without vent...

Objective: The supraglottic airway (SAD) is considered a viable alternative to endotracheal intubation, particularly in cases where SAD not contraindicated. plays crucial role difficult algorithms, offering unobstructed oxygenation and ventilation, as well providing hemodynamic stability with minimal laryngopharyngeal morbidity. LMA-classic, introduced by Archie Brain 1983, was the first second...

Sir,—We read with interest the pilot study by Valentine, Stakes and Bellamy [1] comparing lower oesophageal pH changes in patients managed with either the laryngeal mask airway (LMA) or tracheal tube during intermittent positive pressure ventilation (IPPV). However, we suggest that the following factors in their study design may have had an influence on their results. (1) The authors probably u...

During the last few years there has been growing concern that chronic pulmonary oxygen toxicity might result from the administration of high concentrations of oxygen with intermittent positive pressure ventilation (IPPV) during the management of respiratory failure. This concern was fostered by Nash, Blennerhassett and Pontoppidan (1967) who reported an association between the duration and conc...

BACKGROUND Experimental studies in adult horses have shown that general anaesthesia maintained with isoflurane is associated with less depression of cardiovascular function compared with halothane anaesthesia. Adverse effects of intermittent positive-pressure ventilation (IPPV) have also been demonstrated. Nevertheless, the haemodynamic effects of these agents and the effects of differing modes...

Pneumonia due to Mycoplasma pneumoniae is common, but it is rarely life-threatening. A case is reported in a previously healthy adult whose illness was severe enough to require treatment with intermittent positive pressure ventilation (IPPV) for 14 days and which resolved after treatment with corticosteroids.

BACKGROUND Respiratory failure is of concern in the postoperative period after cardiac surgeries. Invasive ventilation (intermittent positive pressure ventilation [IPPV]) carries the risks and complications of intubation and mechanical ventilation (MV). AIMS Noninvasive positive pressure ventilation (NIPPV) is an alternative method and as effective as IPPV in treating insufficiency of respira...

We postulated that prolonged exposure to intermittent positive-pressure ventilation (IPPV) with high pressure (HIPPV) alone without hyperoxia promotes the development of airway hyperresponsiveness and remodeling. To test this hypothesis, young rats were ventilated under halothane anesthesia with HIPPV (maximum inspiratory pressure at 32-35 cmH2O in 70% nitrous oxide and 30% O2) for 3.5-4 h dail...
