Accuracy of tidal breathing measurement of FloRight compared to an ultrasonic flowmeter in infants.

INTRODUCTION Monitoring breathing pattern is especially relevant in infants with lung disease. Recently, a vest-based inductive plethysmograph system (FloRight®) has been developed for tidal breathing measurement in infants. We investigated the accuracy of tidal breathing flow volume loop (TBFVL) measurements in healthy term-born infants and infants with lung disease by the vest-based system in comparison to an ultrasonic flowmeter (USFM) with a face mask. We also investigated whether the system discriminates between healthy infants and those with lung disease. METHODS Floright® measures changes in thoracoabdominal volume during tidal breathing through magnetic field changes generated by current-carrying conductor coils in an elastic vest. Simultaneous TBFVL measurements by the vest-based system and the USFM were performed at 44 weeks corrected postmenstrual age during quiet unsedated sleep. TBFVL parameters derived by both techniques and within both groups were compared. RESULTS We included 19 healthy infants and 18 infants with lung disease. Tidal volume per body weight derived by the vest-based system was significantly lower with a mean difference (95% CI) of -1.33 ml/kg (-1.73; -0.92), P < 0.001. Respiratory rate and ratio of time to peak tidal expiratory flow over total expiratory time (tPTEF/tE) did not differ between the two techniques. Both systems were able to discriminate between healthy infants and those with lung disease using tPTEF/tE. CONCLUSION FloRight® accurately measures time indices and may discriminate between healthy infants and those with lung disease, but demonstrates differences in tidal volume measurements. It may be better suited to monitor breathing pattern than for TBFVL measurements.

Betriebsanleitung zum Schweizerischen Strafgesetzbuch. Allgemeiner Teil. 1. Auflage

Die Betriebsanleitung zum Allgemeinen Teil I des Strafgesetzbuches versteht sich als neue Form von Lehrmittel. Sie will Studierende zur Arbeit mit dem Gesetzestext anleiten, den sie ob all der Grundlagenprobleme gerade zu Beginn ihres Studiums im Strafrecht vielfach vernachlässigen. Das StGB ist jedoch Grundlage und Ausgangspunkt jeden Nachdenkens über das geltende Recht. Seine Vorschriften enthalten, so knapp sie mitunter auch sein mögen, wichtige Informationen, mit deren Aneignung sich der ebenso abstrakte wie differenzierte Stoff der Straftatkonzeption besser meistern lässt. Das Kurzlehrbuch behandelt die wichtigsten theoretischen Lehren des Aufbaus der allgemeinen Verbrechenslehre, veranschaulicht sie mit Gesetzesauszügen und demonstriert die Gesetzesanwendung anhand zahlreicher Praxisbeispiele. Ein Glossar am Ende rundet das Lehrmittel ab.
