CARDIAX® PC-EKG
Dieser Report beschreibt die Entwicklung des CARDIAX® PC-EKGs vom Beginn der Markt-Präsentation im Jahre1990 bis hin zur heutigen Version. CARDIAX®, das PC-EKG im Wandel der Zeit.
Das CARDIAX® EKG-Gerät ist ein PC-EKG. Mit moderner Mikroelektronik, kombiniert mit validierter kardiologischer Software ist das CARDIAX PC-EKG der ideale Baustein für einen hochwertigen CARDIAX 12-Kanal EKG-Arbeitsplatz mit einem Belastungs-EKG und optionaler Pulsoximetrie (SpO2-Messung). Konsequent wird den Anforderungen der PC-Technik Rechnung getragen. Der CARDIAX PC-EKG USB-Anschluss zur Datenübertragung und Stromversorgung oder die Wireless-Verbindung der WiFi Version mit Akkubetrieb ermöglichen zusätzlich den mobilen EKG-Einsatz …

Oximetry in Aviation
Fundamentals, aspects and recommendations for use of Pulse Oximetry in Aviation
Hypoxia is could be one of the more insidious hazards of flight. Pilots are learning in primary flight training that the higher they are flying, the less oxygen is available in the atmosphere. Additionally it is a fact that one of the effects of hypoxia is a feeling of being well. Measuring blood oxygenation level is critical to flagging hypoxia before it is too late. In non-pressurized aircrafts, the pilot will know to either use supplemental oxygen or descend to a safer altitude. In airplanes with a pressurized cabin, the pilot will be alerted to possible failures of the pressurization system…

Abstract QT-Zeit
Abstract on QT time, QTc time calculation, general principles and psychotropic drug-associated QTc interval prolongation
The determination of the QT interval is particularly difficult if the amplitude of the T-wave is low and therefore the end of the T-wave is difficult to be defined.
The intervals should be measured manually from a 12-lead ECG (usually from limb lead II) and then the mean value from three to five beats is to be calculated. Since the repolarization period shortens with increasing heart rate, a frequency correction of the QT interval should be done…
