Cardiopulmonary Resuscitation:
The artificial substitution of heart and lung action as indicated for Heart arrest resulting from electric shock, Drowning, respiratory arrest, or other causes. The two major components of cardiopulmonary resuscitation are artificial ventilation (Respiration, Artificial) and closed-chest Cardiac massage.

Normothermic Cardiac Arrest and Cardiopulmonary Resuscitation: A Mouse Model of Ischemia-Reperfusion Injury
1Department of Anesthesiology and Perioperative Medicine, Oregon Health & Sciences University, 2Department of Pharmacology, University of Colorado Denver
A powerful model for perioperative and critical care related acute kidney injury is presented. Using whole body hypoperfusion induced by cardiac arrest it is possible to nearly replicate the histologic and functional changes of clinical AKI.

A Swine Model of Neonatal Asphyxia
1Departments of Pediatrics, Pharmacology and Surgery, University of Alberta, 2Department of Surgery, University of Alberta
Large animal models have good translational values in the examination of physiology and pharmacology of neonatal asphyxia. Using newborn piglets, we develop an experimental protocol to simulate neonatal asphyxia which has advantages of studying the systemic and regional hemodynamics, oxygen transport with biochemical and pathologic pathways and correlations.

Tilt Testing with Combined Lower Body Negative Pressure: a "Gold Standard" for Measuring Orthostatic Tolerance
Department of Biomedical Physiology and Kinesiology, Simon Fraser University
We describe a "gold standard" for evaluating orthostatic tolerance (OT) using tilt testing with combined lower body negative pressure (LBNP). This can be combined with non-invasive evaluations of cardiovascular reflex control. Normal and abnormal responses are defined.

Colon Ascendens Stent Peritonitis (CASP) - a Standardized Model for Polymicrobial Abdominal Sepsis
Department of Surgery, University of Greifswald
The Colon Ascendens Stent Peritonitis (CASP) is a highly standardized model for polymicrobial abdominal sepsis in rodents. This article describes the surgical procedure of CASP. The CASP model and its variants allow the systematic investigation of various problems concerning the subject of sepsis.

Improving IV Insulin Administration in a Community Hospital
When compared to the previous paper protocol, implementation of a computerized glucose management system results in a substantial increase in blood glucose concentration measurements within the target range. Using a computerized glucose management system to monitor blood glucose levels, decreases in severe hypoglycemia (<40 mg/dL), clinical hypoglycemia (<70 mg/dL), and hyperglycemia (>180 mg/dL) also can be observed.

Pseudofracture: An Acute Peripheral Tissue Trauma Model
1Department of Surgery, University of Pittsburgh, 2Department of Orthopedic Surgery, University of Aachen Medical Center
Pseudofracture, a reproducible murine model of sterile musculoskeletal trauma, allows for evaluation of late term post-traumatic immune responses. This article describes the procedural execution of the model step by step, including the potential for experimental model combinations to permit study of multiple trauma.

In vivo Measurement of the Mouse Pulmonary Endothelial Surface Layer
Division of Pulmonary Sciences and Critical Care Medicine, University of Colorado School of Medicine
The endothelial glycocalyx/endothelial surface layer is ideally studied using intravital microscopy. Intravital microscopy is technically challenging in a moving organ such as the lung. We demonstrate how simultaneous brightfield and fluorescent microscopy may be used to estimate endothelial surface layer thickness in a freely-moving in vivo mouse lung.
