accuracy of respiratory rate monitoring using a non invasive Acoustic Method after general anaesthesia
BJA: British Journal of Anaesthesia, 2012Co-Authors: Olivier Mimoz, Thierry Benard, A Gaucher, D Frasca, B DebaeneAbstract:Background Respiratory rate should be monitored continuously in the post-anaesthesia care unit (PACU) to avoid any delay in the detection of respiratory depression. Capnometry is the standard of care but in extubated patients requires a nasal cannula or a face mask that may be poorly tolerated or can be dislodged, leading to errors in data acquisition and false alarms. The value of a new non-invasive Acoustic monitor in this setting has not been fully investigated. Methods Adult patients admitted to the PACU after general anaesthesia were included. After tracheal extubation, an adhesive sensor with an integrated Acoustic transducer (RRa™) was placed on the patient's throat and connected to its monitor while the patient breathed through a face mask with a carbon dioxide sampling port (Capnomask™) connected to a capnometer. Both the Acoustic monitor and the capnometer were connected to a computer to record one pair of data per second for up to 60 min. Results Fifty-two patients, mean (range) age 54 (22–84) yr and BMI 26 (19–39) kg m−2, were studied. Compared with capnometry, the bias and limits of agreement of the Acoustic Method were 0 (−1.4–1.4) bpm. The Acoustic sensor was well tolerated while the face mask was removed by eight patients, leading to study discontinuation in two patients. Conclusions In extubated patients, continuous assessment of respiration rate with an Acoustic monitor correlated well with capnometry.

Full-Scale Hot Cell Test of an Acoustic Sensor Dedicated to Measurement of the Internal Gas Pressure and Composition of a LWR Nuclear Fuel Rod
IEEE Transactions on Nuclear Science, 2013Co-Authors: J-y. Ferrandis, Gaël Leveque, J. C. Segura, G. Cécilia, D. Baron, Etai Rosenkrantz, O. ProvitinaAbstract:A full-scale hot cell test of the internal gas pressure and composition measurement by an Acoustic sensor was carried out successfully between 2008 and 2010 on irradiated fuel rods in the LECA-STAR facility at CADARACHE Centre. The Acoustic sensor has been specially designed in order to provide a non-destructive technique to easily carry out the measurement of the internal gas pressure and gas composition (mainly Helium-Xenon mixture, with a small amount of Krypton) of a LWR nuclear fuel rod. This sensor has been achieved in 2007 and is now covered by an international patent. We performed the gas characterisation contained in irradiated fuel rods. The Acoustic Method accuracy is now ±5 bars on the pressure measurement result and {±}0.3% on the evaluated gas composition. The results of the Acoustic Method were compared to puncture results (destructive sampling). Another significant conclusion is that the efficiency of the Acoustic Method is not altered by the irradiation time, and possible modification of the cladding properties. The sensor-operating characteristics have not been altered by a two-year exposure in the hot cell conditions. These results make it possible to demonstrate the feasibility of the technique on irradiated fuel rods. The transducer and the associated Methodology are now operational.

Full-scale hot cell test of an Acoustic sensor dedicated to measurement of the internal gas pressure and composition of a LWR nuclear fuel rod
2011 2nd International Conference on Advancements in Nuclear Instrumentation Measurement Methods and their Applications, 2011Co-Authors: J-y. Ferrandis, Gaël Leveque, J. C. Segura, G. Cécilia, D. Baron, Etai Rosenkrantz, O. ProvitinaAbstract:A full-scale hot cell test of the internal gas pressure and composition measurement by an Acoustic sensor was carried on successfully between 2008 and 2010 on irradiated fuel rods in the LECA-STAR facility at CADARACHE Centre. The Acoustic sensor has been specially designed in order to provide a nondestructive technique to easily carry out the measurement of the internal gas pressure and gas composition of a LWR nuclear fuel rod. This sensor has been achieved in 2007 and is now covered by an international patent. The first positive result, concerning the device behaviour, is that the sensor-operating characteristics have not been altered by a two-year exposure in the hot cell ambient. We performed the gas characterisation contained in irradiated fuel rods. The Acoustic Method accuracy is now ±5 bars on the pressure measurement result and ±0.3% on the evaluated gas composition. The results of the Acoustic Method were compared to puncture results. Another significant conclusion is that the efficiency of the Acoustic Method is not altered by the irradiation time, and possible modification of the cladding properties.
