2. 1. Extracting Cardiac Information From the Pressure Sensors of a Dialysis Machine

   Author : Mattias Holmer; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemodialysis; extracorporeal pressure signals; cardiac pressure signal; heart rate; ventricular premature beats; venous needle dislodgement;

   Abstract : This doctoral thesis in biomedical engineering deals with cardiac monitoring using the built-in extracorporeal blood pressure sensors of a hemodialysis machine. Patients treated with hemodialysis often suffer from cardiovascular disease. READ MORE

4. 2. Intracranial Pressure in Traumatic Brain Injury

   Author : Sima Shahsavari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain Swelling; Cerebral Autoregulation; Secondary Brain Injury; Traumatic Brain Injury; Cerebral Compliance; Intracranial Dynamics; Intracranial Pressure;

   Abstract : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainely focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity (ICP) has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. READ MORE

5. 3. Myocardial Topical Negative Pressure

   Author : Sandra Lindstedt Ingemansson; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary blood flow; microvascular blood flow; topical negative pressure TNP ;

   Abstract : The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. READ MORE

6. 4. Splanchnic perfusion in cardiac surgery

   Author : Anders Thorén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Splanchnic circulation; jejunal mucosal perfusion; laser Doppler flowmetry; cardiopulmonary bypass; cardiac surgery; inotropic agents; gastric tonometry; sympathetic reflex;

   Abstract : Splanchnic ischemia in cardiac surgery is considered a risk factor in the development of the Multiple Organ Dysfunction Syndrome (MODS), which is the leading cause of morbidity and mortality in the intensive care unit. Splanchnic ischemia/reperfusion may lead to an injury of the intestinal mucosa and induce a systemic inflammation (SIRS), which is proposed to precede MODS. READ MORE

7. 5. Cardiovascular and respiratory effects of apnea in humans

   Author : Johan Andersson; Funktionell zoologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

   Abstract : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. READ MORE
