Measurement Of The Frequency Response Of Clinical Gas Analysers, Kabita Shakya, Catherine Deegan, Fran Hegarty, Charles Markham
Measurement Of The Frequency Response Of Clinical Gas Analysers, Kabita Shakya, Catherine Deegan, Fran Hegarty, Charles Markham
The ITB Journal
A technique for the time and frequency response measurement of clinical CO2 analysers has been established. The time and frequency response of several analyser systems has been determined. This paper presents the case for the routine measurement of the dynamic performance of such systems in the context of their application in high-frequency ventilation schemes. The importance of these measurements has been demonstrated in the comparison of older and newer systems in the sense that older systems demonstrate significant deterioration in peiformance. In the context of the use of capnographs in life-support systems, it is essential to measure and monitor the …

The decreasing costs of microprocessor systems and increasing range of “Smart Sensors” have led to a boom in Assistive Device Technology. The annual rate of expenditure for mobility related devices has reached $1 billion dollars in the United States alone. The industries current focus is to develop a wider range of Independent Mobility Controllers to allow, even the most severely disabled person, the ability to control an Electric Powered Wheelchair (EPW). Advances in Autonomous Robot Design have led to corresponding improvements in EPW technology. This paper outlines user interfaces and input device technologies used at present to navigate an EPW.

In a health care environment, mechanical ventilation is used to support patients during acute illness and surgery. Mechanical ventilation is the process by which the patient’s respiratory function is artificially supported using a respirator. During mechanical ventilation, it is necessary to ensure the adequacy of ventilation. The patient is thus monitored for several ventilatory parameters. The end-tidal CO2 (EtCO2) is one of the primary monitoring parameters. EtCO2 is the partial pressure or maximal concentration of carbon dioxide (CO2) at the end of an exhaled breath, which is expressed as a percentage of CO2 or mmHg . Capnography is the technique …
