No full textUncalibrated continuous cardiac output measurement in liver transplant patients: LiDCOrapidTM system versus pulmonary artery catheter
No full textObjective: The aim of the study was to assess the level of agreement between continuous cardiac output estimated by uncalibrated pulse-power analysis (PulseCOLiR) and intermittent (ICO) and continuous cardiac output (CCO) obtained using a pulmonary artery catheter (PAC).
Design: Prospective cohort study.
Setting: University hospital intensive care unit.
Participants: Twenty patients after liver transplantation. Intervention: Pulmonary artery catheters were placed in all patients, and ICO and CCO were determined using thermodilution. PulseCOLiR measurements were made using a LiDCOrapidTM (LiDCO Ltd, Cambridge, UK).
Measurements and Main Results: ICO data were deter- mined after intensive care unit admission and every 8 hours until the 48th postoperative hour. CCO and PulseCOLiR measurements were recorded simultaneously at these same time intervals as well as hourly. For the 8-hour data set (140 data pairs), the mean bias and percentage errors (PE) were, respectively, 0.10 L/min and 39.2% for ICO versus Pulse- COLiR and 0.79 L/min and 34.6% for CCO versus PulseCOLiR. For the hourly comparison of CCO versus PulseCOLiR (980 data pairs), the bias was 0.75 L/min and the PE 37%. To assess the ability to measure change, a 4-quadrant plot was produced for each pair of methods. The performance of PulseCOLiR was moderate in detecting changes in ICO.
Conclusions: In conclusion, the uncalibrated PulseCOLir method should not be used as a substitute for the thermo- dilution technique for the monitoring of cardiac output in liver transplant patients
Persistent hypoxemia after an asthma attack
No full textAbstract The presence of an unknown intracardiac shunt due to a patent foramen ovale may be an unusual cause of hypoxemia. We report the case of a patient who presented persistent hypoxemia after an adequate treatment for a severe asthma attack requiring intensive care unit admission. The patient underwent a transthoracic microbubbles contrast echocardiography that showed a massive patent foramen ovale. The favorable clinical course and the absence of major signs and symptoms related to patent foramen ovale allowed a conservative approach with a follow-up program. Patent foramen ovale should be suspected in case of persistent hypoxemia after a severe asthma attack had resolved
Design and development of group 13 precursors for improved vapour deposition of metal nitride thin films
No full textAtomic layer deposition (ALD) and chemical vapour deposition (CVD) are important techniques to deposit thin films for a variety of applications. Metal oxides and nitrides are used as passivation layers and as dielectrics, and due to the increasingly small sizes of microelectronic devices, their depositions must be precise, conformal, and of high purity. This work examines how precursor design can reduce impurities in deposited films. Several novel precursors have been designed, synthesized, and characterized, and used to deposit a variety of group 13 nitride thin films. Bidentate ligands such as guanidinates, NacNacs and azenides have been explored, as have simpler ligand systems such as amides and hydrides. The importance of precursor design is emphasized due to the fact that it enables the development of new, volatile, and thermally stable compounds and ALD processes that will deposit pure, high-quality films in a cost- and time-efficient manner
