UNLABELLED We performed a retrospective analysis to the effects of negative pressure ventilation (NPV), tracheal intermittent positive pressure ventilation (TIPPV), and nasal intermittent positive pressure ventilation (NIPPV, volume or pressure-controlled ventilatory mode), in 114 patients with restrictive ventilatory disorders instituted in our hospital from 1956 until 2005. The patients were ...

Objective—To investigate the eVects of cuirass negative pressure ventilation on the cardiac output of a group of anaesthetised children after occlusion of an asymptomatic persistent arterial duct, and a group of paediatric patients in the early postoperative period following cardiopulmonary bypass. Design—Prospective study. Setting—The paediatric intensive care unit and catheter laboratory of a...

OBJECTIVE To investigate the effects of cuirass negative pressure ventilation on the cardiac output of a group of anaesthetised children after occlusion of an asymptomatic persistent arterial duct, and a group of paediatric patients in the early postoperative period following cardiopulmonary bypass.

OBJECTIVE To evaluate the effect of intermittent pneumatic leg compression on intracranial pressure and cerebral perfusion pressure in brain-injured patients. DESIGN Prospective, sequential patient study. SETTING Surgical/trauma ICU of a community hospital providing regional trauma care. PATIENTS Twenty-four adult, brain-injured patients (mean Glasgow Coma Scale score = 6) who required he...

A versatile new anaesthetic machine embodying a ventilator with automatic and manual closed circuits, and with provision for semi-open circuits is described. The ventilator follows the principle of volume and time cycling and generally requires only a low flow of fresh gases (about 2 l./min). It is based on the original Smith-Clarke intermittent positive/ negative pressure respirator and is bot...

A 49 yr old poliomyelitic patient had been under cuirass-type nocturnal negative pressure ventilation for more than 20 yrs. He had a severe restrictive ventilatory impairment, and normal awake blood gases at rest and during light exercise. He was offered a trial of intermittent positive pressure ventilation applied through the nose (nIPPV). Two daytime studies and one night study were carried o...

Intermittent positive-pressure breathing is thought to avoid atelectasis and improve pulmonary function after major lung resections. Since no clear scientific data was available to confirm this, our objective was to determine whether atelectasis can be avoided and if postoperative lung function is improved. Prospective analysis was carried out in 135 patients operated on between 2007 and 2009; ...
