研究概览
简要总结
The purpose of the trial is to confirm that the presence of the Proxima 3 disposable in the arterial line doesn't significantly attenuate the arterial pressure wave form. The principal aim of the trial will be:
• To obtain quantitative data allowing investigation of the pressure wave form obtained in a standard arterial line compared to various arterial lines fitted with the Proxima 3.
详细描述
The purpose of this study is to examine the transmission of the arterial pressure wave form through Proxima 3 disposable attached to a configurable parts of the patient's arterial line. The Proxima device has been tested by Intertek as part of the Proxima 2 project and found to comply to BS EN 60601-1 2nd edition "Medical electrical equipment - Part 1: General requirements for basic safety and essential performance". Additional internal tests have also been carried out for clause 51.103, frequency response, from BS EN 60601-2-34(2001).
This study part of the on-going development of the Proxima system which monitors metabolic parameters in critically ill patients using a disposable sensor array. This study builds upon the four clinical trials carried out in the past two years by Sphere Medical in partnership with the NHS (REC references: 10/H1308/53, 10/H0308/113, 11/SW/0166, 12/SW/0175).
This study forms part of the development process for the Proxima family of devices.
The Proxima 3:
- Is a disposable multi-parameter microanalyser
- Is connected into the patient's arterial line.
- Will measure all or some of blood gases, haematocrit and electrolytes and is connected to a small bedside monitor, which displays the results.
- Microanalyser can perform an unlimited number of analyses over a period of up to seventy two hours.
- Will be used as part of a closed system, reducing infection risk and preventing blood loss.

结局指标
主要结局
To confirm that siting Proxima 3 in the arterial line does not affect the pressure wave form
时间窗: 10 minutes maximum
The data traces collected from the arterial pressure waveform monitor will undergo quantitative assessment to determine the effect on the pressure wave, if any, by introducing the Proxima 3 device in the system.
