Early decrease of skin blood flow in response to locally applied pressure in diabetic subjects.
Pressure ulcers are common debilitating complications of diabetes that are caused by tissue ischemia. Skin blood flow in response to locally applied pressure might be impaired in diabetic patients because of the combined effects of a typically low skin temperature and alterations in microcirculatory function, and could be worsened by neuropathy. We measured skin blood flow by laser Doppler flow...
متن کاملUsing wavelet analysis to characterize the thermoregulatory mechanisms of sacral skin blood flow.
Pressure-induced skin blood flow responses measured via laser Doppler flowmetry are commonly reported in the time domain. The usefulness of spectral analysis in examining blood flow control mechanisms has been demonstrated, but traditional Fourier analysis does not provide sufficient resolution to reveal characteristic low frequencies. Time-frequency (wavelet) analysis was performed on 10 subje...
متن کاملPressure-support Ventilation in the Operating Room
To the Editor:—I read with interest the study by Jaber et al. and the accompanying editorial by Tantawy and Ehrenwerth regarding pressure-support ventilation (PSV). The Jaber study is noteworthy for documenting that the performance of PSV using modern anesthesia ventilators approaches the performance of an intensive care unit ventilator. The editorial correctly indicates that the testing was no...

متن کاملRelationship between Sacral Skin Blood Flow Oscillations and Vasodilatory Functions in People at Risk for Pressure Ulcers
The role of microvascular function in the risk for pressure ulcers can be assessed by studying the changes of skin blood flow oscillations (BFO) in response to causative factors of pressure ulcers such as local heating [1]. Previous studies, using either Fourieror wavelet-based spectral analysis, provide essential contributions to the understanding of the control mechanisms of BFO [2]. Wavelet ...
