Sepsis in Sweden causes ~1000 deaths per year21. In sepsis diagnostics delay in appropriate antibiotic therapy increases the mortality by 7.6% with each passing hour22. To date, blood culturing is considered as the gold standard in identifying the Bioparticle Manipulation using Acoustophoresis and Inertial Microfluidics BAKGRUND Sepsis och septisk chock är livshotande tillstånd som kräver omedelbart omhändertagande.Sepsis medför en livshotande infektionsutlöst systempåverkan och organdysfunktion. Septisk chock föreligger om patienten har hypotension (medelartärtryck 2 mmol/l trots adekvat vätsketillförsel. Multipel organsvikt orsakad av sepsis utgör en vanlig dödsorsak på 2018-06-14 · Sepsis is a systemic response to an infection, and the severe form is a common condition with a yearly incidence rate of 0.3% in the US, and mortality as high as 29% 1.This makes sepsis one of the Sepsis is an acute and sometimes deadly reaction to an infection, usually caused by bacteria. Identifying the bacteria by blood culture often takes several days, which may be too long to save the patient. We have previously developed an acoustophoresis-based method to directly extract bacteria from a blood sample for analysis without culture [1].

88, Suspected sepsis was defined according to the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) Consensus Conference as an infection and the presence of at least two of the systemic inflammatory response syndrome (SIRS) criteria: temperature >38 °C or <36 °C, heart rate >90 beats/min, respiratory rate >20 breaths/min, or white blood cell count (WBC) >12 000 or <4000 cells/L.

the unmet clinical need for rapid sepsis diagnostics. The blood sample is first processed in an acoustophoresis chip, where red blood cells are focused to the center of the channel by an acoustic standing wave and

This loss of precious time used for identification process 2018-06-14 Acoustophoresis, the ability to acoustically manipulate particles and cells inside a microfluidic channel, is a critical enabling technology for cell-sorting applications. However, one of the major impediments for routine use of acoustophoresis at clinical laboratory has been the reliance on the inherent physical properties of cells for separation. Acoustophoresis is a label-free separation technique where particles exposed to an acoustic standing wave field are affected by an acoustic radiation force. A microchannel having a width matched to a half-wavelength of the actuation frequency displays a single pressure node along the … Acoustophoresis: the art of combining acoustics and microfluidics. The manipulation of particles is an essential feature of Lab-on-a-chip (LOC) devices. LOC-systems provide a platform where biochemical assays can be miniaturized, integrated and automated in a simple, portable, fast and cost-efficient way [1].

This paper describes an integrated microsystem for rapid separation, enrichment, and detection of bacteria from blood, addressing the unmet clinical need for rapid sepsis diagnostics. The blood sample is first processed in an acoustophoresis chip, where red blood cells are focused to the center of the channel by an acoustic standing wave and sequentially removed. The bacteria-containing plasma

Almost any type of infection can lead to sepsis. Sepsis is a serious infection that causes your immune system to attack your body. As a result of that attack, septic shock can occur and result in death.

The objective of ACUSEP was to develop a disposable ready-to-use cartridge enabling rapid analysis of sepsis-causing organisms directly from suspected blood samples. Acoustophoresis, as an alternative microfluidic cell handling technique, offers a label-free and continuous cell separation that provides both high throughput and good separation performance for Final Report Summary - ACUSEP (Integrated whole blood acoustophoresis and homogeneous nucleic acid detection cartridge for rapid sepsis diagnostics) Executive Summary: The aim of the ACUSEP project was to provide a proof-of-concept of a new method for sepsis diagnostics that would enable the identification of sepsis causing bacterium directly from a blood sample within a couple of hours. The blood sample is first processed in an acoustophoresis chip, where red blood cells are focused to the center of the channel by an acoustic standing wave and sequentially removed. The bacteria-containing plasma proceeds to a glass capillary with a localized acoustic standing wave field where the bacteria are trapped onto suspended polystyrene particles. Sepsis is a common and often deadly systemic response to an infection, usually caused by bacteria. The gold standard for finding the causing pathogen in a blood sample is blood culture, which may take hours to days. Shortening the time to diagnosis would significantly reduce mortality.
