2. 1. Extreme hemodilution: Effects of inhalation anesthetics, hypoxia, and blood loss. An Experimental study in pigs

   Author : Henning Schou; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; oxygen saturation.; blood volume; coronary circulation; blood lactate; oxygen uptake; Anemia; oxygen delivery; intensive care; Anestesiologi; intensivvård;

   Abstract : Hemodilution reduces the need for blood transfusion and hereby the risk for transmission of infectious agents. The present study investigated effects on systemic and myocardial circulation and oxygenation, and blood lactate concentrations; induced by nitrous oxide, isoflurane, hypoxia, and uncompensated blood loss, in pigs hemodiluted to a hematocrit of 11%.

5. 3. Blood pressure, renal functional and structural changes, in normal and preeclamptic pregnancy

   Author : Helena Strevens; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; renal biopsy; renal function; pregnancy; preeclampsia; physiology; parity; endotheliosis; cystatin C; Blood pressure; BMI; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

   Abstract : The kidneys play a pivotal role in the adaptive physiology of the pregnant woman, presenting some changes at term similar to the changes found in preeclampsia – a state of increased risk of fetal and maternal morbidity and mortality. The aim of these investigations was to explore possible similarities in blood pressure regulation, renal function and structure in normal term and preeclamptic pregnancy, to ascertain whether both conditions in fact are different degrees of an adaptive process in reaction to pregnancy.

6. 4. Blood volume expansion following supramaximal exercise : occurrence and contribution to maximal oxygen uptake

   Author : Mirko Mandić; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Previously published research using various types of exercise has shown that central hemodynamic factors such as blood volume (BV) and maximal cardiac output (Qmax) are of large importance in the mediation of improvements in VO2max. Whether this is true for adaptations induced by sprint-interval training (SIT) is unclear. READ MORE

7. 5. Minimally invasive cardiorespiratory monitoring and lung recruitment manoeuvres. Studies in animals and humans

   Author : Helena Odenstedt; Göteborgs universitet; []
   Keywords : Monitoring; cardiac output; lung volume; lung recruitment manoeuvre; regional ventilation; acute lung injury; bronchoalveolar lavage; endotoxin; cardiac tamponade;

   Abstract : Background: The maintenance of adequate oxygen delivery is essential to preserve organ function. The circulatory and respiratory systems interact closely to accomplish this. Optimising the function of these systems is of fundamental importance in critically ill patients. This requires adequate monitoring techniques. READ MORE
