  1. 1. Blood pressure-dependent changes in plasma volume, glycocalyx and platelet function during anaesthesia -Clinical and experimental studies

    Author : Tor Damén; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; blood pressure; hypotension; norepinephrine; haematocrit; plasma volume; atrial natriuretic peptide; glycocalyx; platelet aggregation;

    Abstract : Background: Worldwide, more than 300 million surgeries are performed each year. General anaesthesia provides the surgical patient with a state of controlled loss of sensation and awareness. It is common that general anaesthesia causes hypotension. Anaesthesia-induced hypotension is associated with haemodilution and increased plasma volume (PV). READ MORE

  3. 3. Blood pressure in very old age : determinants, adverse outcomes, and heterogeneity

    Author : Bodil Weidung; Yngve Gustafson; Håkan Littbrand; Bo Carlberg; Peter Nordström; Sölve Elmståhl; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; aged 80 and over; hypertension; hypotension; mortality; stroke; gait speed; cognition disorders; dementia; cohort study;

    Abstract : Background: High blood pressure (BP) is the leading risk factor for disease and mortality worldwide. However, risks associated with high BP in very old age (≥ 80 or ≥ 85 years) are not entirely understood, as the majority of scientific studies have been performed with younger populations and existing scientific knowledge about very old individuals is sometimes contradictory.

  4. 4. Posture and brain function in dementia. A study with special reference to orthostatic hypotension

    Author : Ulla Passant; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; falls and fractures.; white matter disease; hypoperfusion; frontal lobes; regional cerebral blood flow; blood pressure; orthostatic hypotension; Organic dementia; normal subjects; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

    Abstract : Orthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. READ MORE

  5. 5. Signal Modeling and Detection in Nephrologic and Cardiac Applications

    Author : Kristian Solem; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heart rate turbulence HRT ; Heart rate variability HRV ; Electrocardiogram ECG ; Pulse oximetry.; Biomedical signal processing; Intradialytic hypotension; Hemodialysis; Ectopic beats;

    Abstract : This doctoral thesis is comprised of five parts in the field of biomedical signal processing with focus on methods for use in hemodialysis as well as in cardiac applications. The problem of predicting hypotension is the main concern in the parts were data from patients undergoing hemodialysis are used. READ MORE
