Minitracheostomy for effective pulmonary toilet was performed on day 5. However, he maintained a saturation of 94%, PaO2 of 64 mmHg and respiratory rate of 35–40 on ventimask. He was advised HFNC oxygenation with a peak inspiratory flow of 50 L/min and FiO2 of 60% initially by device (AIRVO 2 ® Fisher Packel, Auckland, New Zealand). Initially, the patient showed improved saturation to 100% with...

INTRODUCTION The need to reduce pollution emissions in the operating room and to reduce treatment costs motivates more frequent use of general anaesthesia with a small or minimal fresh gas flow rate. Nevertheless, the reduction of the delivery of fresh gases should not influence the quality and safety of the anaesthesia. MATERIAL AND METHODS A total of 105 elective laparoscopic cholecystectom...

We present a numerical analysis of an implicit time discretization method applied to Richards’ equation. Written in its saturation-based form, this nonlinear parabolic equation models water flow into unsaturated porous media. Depending on the soil parameters, the diffusion coefficient may vanish or explode, leading to degeneracy in the original parabolic equation. The numerical approach is base...

when the degree of saturation at intersection approaches one, webster’s optimum cycle length equation becomes inapplicable, because the cycle length will becomes very big when the degree of saturation approaches one and will be fully unrealistic when the degree of saturation becomes greater than one. this is not a problem for hcm2000 method. but optimum cycle length calculation in this method h...

A major challenge in runoff and soil erosion modelling is the adequate representation of most relevant processes models while avoiding over parameterization. In European loess belt, progressive crusting during rainfall events, resulting infiltration-excess runoff, usually considered dominant process generating on catchments covered with silty soils. Saturation-excess may also occur affect their...

We measure tissue blood flow markers in breast tumors during neoadjuvant chemotherapy and investigate their correlation to pathologic complete response in a pilot longitudinal patient study (n  =  4). Tumor blood flow is quantified optically by diffuse correlation spectroscopy (DCS), and tissue optical properties, blood oxygen saturation, and total hemoglobin concentration are derived from conc...
