Pulmonary Compliance and Mechanical Ventilation
Archives of Surgery, 1992Normal, spontaneous breathing begins with contraction of the muscles of inspiration, which effect expansion of the thoracic cage and create a pressure in the pleural space that is negative with respect to that of the atmosphere. Since the airway pressure in the lung at end-expiration is in equilibrium with the atmosphere, the transthoracic negative ...

Pulmonary Ventilation during Hemodialysis
Nephron, 2008During hemodialysis a decrease in pulmonary ventilation has been reported. The elimination of CO<sub>2</sub> across the dialyzer has been suggested as the cause of the pulmonary hypoventilation. Our purpose was to analyze the factors that could have influenced the pulmonary ventilation of 7 patients with chronic renal failure during ...

Nasogastric Tube and Pulmonary Ventilation
Archives of Surgery, 1963The belief is widely held that a nasogastric tube adversely affects pulmonary ventilation, interferes with coughing, and predisposes to postoperative atelectasis. This impression is undoubtedly in part responsible for the present tendency to avoid nasogastric suction after major abdominal operations.

PULMONARY COMPLICATIONS OF MECHANICAL VENTILATION
Clinics in Chest Medicine, 1999Although life-saving, mechanical ventilation may be associated with many complications, including consequences of positive intrathoracic pressure, the many aspects of volutrauma, and adverse effects of intubation and tracheostomy. Optimal ventilatory care requires implementing mechanical ventilation with attention to minimizing adverse hemodynamic ...

A method of recording pulmonary ventilation
Journal of Physics E: Scientific Instruments, 1968By use of a simple chopper-disk and electronic circuitry a respiratory type gasmeter may be modified quite simply and provide permanent records on a chart recorder. Visual presentation of ventilation by means of a moving coil meter and electromagnetic counter is available when paper records are not required.

2008
Gas imaging has opened the new field of direct imaging of pulmonary ventilation by MRI. The use of hyperpolarised 3He gas for MRI of the lung has been pioneered by a number of groups worldwide. Due to the enormous progress in the fields of hyperpolarisation technology, administration of hyperpolarised 3He, MR hardware, and MR pulse sequences ...
