Diaphragm Electrical Activity

Christer Sinderby Diaphragm Electrical Activity: Post 1 October 26, 2012 - Post 1: The basics About the EAdi blog Having spent my career on topics involving the acquisition, processing, physiology, and implementation of Electrical Activity of the Diaphragm (EAdi), I initiated this blog to try to create a community for those
Christer Sinderby Diaphragm Electrical Activity: Post 2 November 11, 2012 - Post 2: Acquisition and processing of the EAdi signal The EAdi signal processing is a fascinating area of development where new materials and increased processing power have allowed us to make endless decisions in real time. The blog below describes
Christer Sinderby Diaphragm Electrical Activity: Post 3 December 17, 2012 - Post 3: Physiological interpretation of the diaphragm electrical activity (EAdi) waveform. Breathing is an extremely complex process and we are still learning. The EAdi waveform adds a new dimension to interpreting breathing at the bedside. It provides information about central
Christer Sinderby Diaphragm Electrical Activity: Post 4 May 6, 2013 - Post 4: Esophageal vs. Surface EMG measurements Introduction Electrical activity (also referred to as the electromyogram – EMG) of respiratory muscles has been used for decades, to for example asses activation and fatigue. I have previously described the signal principles

Clinical Implementation of NAVA

Leo Heunks Use of NAVA in Clinical Practice: “The Nijmegen Experience” January 8, 2013 - Introduction The Radboud University Nijmegen Medical center is a 1000-bed teaching hospital with 35-bed adult ICU. Our ICU offers a broad spectrum of ICU care including neuro-ICU, medical and surgical ICU, cardiac ICU, extracorporeal CO2 removal, ECMO, expertise center for

Jennifer Beck Year In Review (2014) May 15, 2015 - To begin, a graphical presentation of the publications (PUBMED) over the years (revised December 11, 2014) During the past year, 17 scientific publications, 3 case reports, 6 editorials, and 8 reviews were published, for a total of 33 papers on
Jennifer Beck Growth of NAVA Over the Years: Post 1 September 19, 2012 - They say it can take up to 30 years between the time a product is “invented” to the time it is commercially available.  And then, there is user acceptance, and widespread implementation and continuity of usage which takes even longer.
Jennifer Beck Growth of NAVA Over the Years: Post 2 December 28, 2012 - It’s the end of 2012 and we have reached 34 publications about Edi technology and/or NAVA. (A recount of 2011 indicated 33 publications). This year, there was an increase, and the papers included: 2 case reports, 8 reviews, 21 scientific
Jennifer Beck Publications List (updated December 28, 2012) December 28, 2012 - Sinderby C., Ingvarsson P., Sullivan L., Wickström I., Lindström L. The role of the diaphragm in trunk extension in tetraplegia, Paraplegia, 30: 389-395, 1992 Sinderby C., Ingvarsson P., Sullivan L., Wickström I., and Lindström L. Electromyographic registration of diaphragmatic fatigue
Jennifer Beck Year in Review (2013) NAVA and Edi Monitoring February 5, 2014 - Happy 2014! May this year be filled with new science and improvements in mechanical ventilation!  In 2013, nearly the same number of peer-reviewed papers were published (33 articles in PUB MED) compared to 2012 (35 articles). Over the last 20

Patient Ventilator Interaction

Christer Sinderby Patient Ventilator Interaction: Post 1 April 20, 2013 - Post 1: Proportionality and NAVA level Patient ventilator interaction has generally two dimensions: timing of assist (temporal interaction) and magnitude of assist (interaction in space), both in relation to patients effort. Temporal interaction relates to synchronization of assist delivery to
Christer Sinderby Patient Ventilator Interaction: Post 2 October 2, 2013 - Post 2: Timing of assist As mentioned in my previous blog on patient ventilator interaction: “Patient ventilator interaction has generally two dimensions: timing of assist (temporal interaction) and magnitude of assist (interaction in space), both in relation to patient effort.
