1. 1. The new old normal : reassessing perioperative oxygen consumption and haemodynamics in the elderly

   Författare :Julia Jakobsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Perioperative haemodynamic instability and disturbances of global oxygen transport are associated with complications and organ injury after surgery. The continuously growing population of elderly in surgical care are at higher risk due to age-related cardiovascular alterations and increased prevalence of comorbidities. LÄS MER

   Sammanfattning : Ocean mixing related to rough bathymetry is highly dynamic and exhibits large spatial and temporal variability. Therefore, established in-situ methods as well as numerical models often lack the resolution to capture this type of mixing. In this thesis, acoustics are used to observe, map and quantify stratified mixing at unprecedented resolution. LÄS MER
