Subpleural concentrations of He and SF6 were measured during multiple-breath washouts from isolated dog lungs. Tidal volume, inspiratory flow, and frequency were in the normal range of canine ventilation. For each gas, there was a local minimum in co

Interference in the electrocardiogram (ECG) signal in an operating room environment is common. Interference from a variety of sources, including electrosurgical units and blood warmers, have been reported. We report the occurrence of an ECG signal th

It is generally accepted that a stationary concentration front is established in the tracheobronchial tree during the inspiratory phase of single- and multiple-breath washouts. The anatomic position of this front, which is determined by the balance b

Histogram equalization for display of clinical CT images was evaluated. In theory, histogram equalization makes optimal use of an available grey scale to display an image, and its use could circumvent the problem of selecting specific window settings

Simultaneous washouts of He, N2, and SF6 were monitored during jet ventilation with tidal volumes of 50-200 ml and rates of 1-2 Hz. Gas concentrations were measured from the trachea and from a lower lobe bronchus in six baboons by mass spectrometry.

The present rationale for clinical defibrillation is empirically based, and the technique is the same for different paddle locations and anatomical configurations. Using a two-dimensional finite element model, we studied the effects of such variation

Radiology information systems (RIS) have developed over the past 20 years as a specialized area of medical informatics. Although an increasing number of radiology departments utilize such systems, the majority do not. Perhaps this is because no comme

The Gould-Statham P23id transducer with disposable dome was tested for accuracy between 0 and 20 mm Hg. With a criterion of +/- 2 mm Hg, 16 per cent of 74 systems failed. Inaccuracies were relatively large (SD, 6.02 mm Hg). The source of the unreliab
