Prediction of pulmonary arterial wedge pressure from arterial pressure or pulse oximetry plethysmographic waveform.
To assess the possibility of using arterial pressure waveform or pulse oximetry plethysmographic waveform variation to estimate the pulmonary arterial wedge pressure (PAWP). ⋯ During positive pressure mechanical ventilation, APR, SPV, dDown, SPV(plet) and dDown(plet) can be used to estimate PAWP effectively.

Diagnostic significance of ultrasonography and CT for large upper abdominal mass.
To assess the effect of ultrasonography and computerized tomography (CT) in the diagnosis of large upper abdominal mass. ⋯ Because upper abdomen organs are closely connected with each other, correct imaging localization of a large mass in this region is not easy. In this study, we compared the accuracy of ultrasonography and CT in diagnosing large upper abdominal masses, and found that ultrasonography works better for adrenal rather than liver or kidney. Neither ultrasonography or CT could accurately diagnose a large mass in the spleen.
