Heart rate variability and heart rate asymmetry analysis: does the inspiration/expiration ratio matter?
TO THE EDITOR: In the Journal of Applied Physiology, Wang et al. (2) published their studies on the effects of paced breathing at different inspiration/expiration (I/E) ratios on spontaneous baroreflex sensitivity (BRS), heart rate variability (HRV), and heart rate asymmetry (HRA). The authors concluded that the I/E ratio need not to be set in BRS or spectral HRV analysis. In our recent work (1...
متن کاملFormation of CdS Nanoparticles in Microemulsion Using Different Co-surfactant and Water to Surfactant Molar Ratio
Cadmium Sulphide (CdS) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. The obtained nanoparticles structures were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) whereas optical characterization was done by Ultra Violet-Visible absorption. XRD result shows that CdS nanopart...
متن کاملEndotoxin impairs cardiac hemodynamics by affecting loading conditions but not by reducing cardiac inotropism.
Acute myocardial dysfunction is a typical manifestation of septic shock. Experimentally, the administration of endotoxin [lipopolysacharride (LPS)] to laboratory animals is frequently used to study such dysfunction. However, a majority of studies used load-dependent indexes of cardiac function [including ejection fraction (EF) and maximal systolic pressure increment (dP/dt(max))], which do not ...

Critical Care Medicine www.ccmjournal.org e65 Objective: Cyclic recruitment and derecruitment of atelectasis can occur during mechanical ventilation, especially in injured lungs. Experimentally, cyclic recruitment and derecruitment can be quantified by respiration-dependent changes in Pao2 (ΔPao2), reflecting the varying intrapulmonary shunt fraction within the respiratory cycle. This study inv...
متن کاملChest tube removal: end-inspiration or end-expiration?
BACKGROUND Recurrent pneumothorax is the most significant complication after discontinuation of thoracostomy tubes. The primary objective of the present study was to determine which method of tube removal, at the end of inspiration or at the end of expiration, is associated with a lesser risk of developing a recurrent pneumothorax. A secondary objective was to identify potential risk factors fo...
