The monitoring of physiologic variables is an integral part of the diagnosis and management of the critically ill patient. Restoration of tissue perfusion and oxygen delivery is the ultimate goal for any state of circulatory collapse. Insight into a patient's intravascular volume status and cardiac performance, particularly in the early stages of shock, can help guide management and potentially...

OBJECTIVE Many studies have indicated that intra-abdominal pressure (IAP) is positively correlated with central venous pressure (CVP) in severe cases. However, although elevated IAP is common in patients with severe acute pancreatitis (SAP), its relationship with CVP remains unclear. Our study aimed to investigate the association of IAP with CVP in early-phase SAP patients. METHODS In total, ...

OBJECTIVES To assess the effectiveness and cost-effectiveness of oesophageal Doppler monitoring (ODM) compared with conventional clinical assessment and other methods of monitoring cardiovascular function. DATA SOURCES Electronic databases and relevant websites from 1990 to May 2007 were searched. REVIEW METHODS This review was based on a systematic review conducted by the US Agency for Hea...

the present study is an attempt towards remodeling cost, revenue and profit relationship within the network process. the previous models of data envelopment analysis (dea) have been too general in their scope and focused on the input and the output within a black box system, therefore they have not been able to measure various phases simultaneously within a network system. by using these models...

OBJECTIVE The objective of our study is to assess the correlation between inferior vena cava (IVC) diameters, central venous pressure (CVP) and the IVC collapsibility index for estimating the volume status in critically ill patients. METHODS This cross-sectional study used the convenient sampling of 100 adult medical intensive care unit (ICU) patients for a period of three months. Patients ≥ ...

BACKGROUND AND AIMS Cardiac function may differ after valvular (VS) and coronary artery (CAS) surgery and this may affect assessment of fluid responsiveness. The aim of the study was to compare VS and CAS in the value of cardiac filling pressures and volumes herein. METHODS There were eight consecutive patients after VS and eight after CAS, with femoral and pulmonary artery catheters in place...

STUDY OBJECTIVES A transpulmonary thermal-dye dilution (TDD) technique using cold indocyanine green dye was utilized to monitor cardiac index (CI) and preload in patients after heart transplantation. Preload, determined by intrathoracic blood volume index (ITBVI) and global end-diastolic volume index (GEDVI), was compared to central venous pressure (CVP) and pulmonary artery occlusion pressure ...

Introduction: Maintaining low central venous pressure (CVP) is an effective strategy to reduce blood loss during hepatic resection. As alternative measuring CVP, which requires the placement of a catheter, bioelectrical impedance analysis (BIA) noninvasive method recently used for monitoring volume status in critically ill patients. Methods: We investigated 192 patients who underwent resection ...

The bounded distance decoding (BDD) is a fundamental problem in lattice-based cryptography which derived from the closest vector (CVP). In this paper, we adapt lattice enumeration with discrete pruning, burgeoning method for shortest (SVP), to solve BDD various cryptanalysis scenarios using direct method. We first transfer basic definition involved pruning technique SVP CVP, prove corresponding...
