Local Pressure Effects Clinical Trial
Official title:
An Open, Non-randomised, Study to Provide Data on the Arterial Pressure Wave Form Obtained Through the Proxima 3 in Patients Who Require the Insertion of an Arterial Line
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.
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.
Proxima 3 will enable clinicians to measure blood parameters without leaving the patient's
bedside. This will support the ability to respond rapidly to changing conditions in their
critically ill patients. The measurements made by the Proxima 3 system have the potential to
inform clinical decision support systems and to change, at a fundamental level, the ability
of clinicians to improve patient care.
In this study the Proxima 3 is a passive component. It will NOT be connected to the Proxima
3 monitor. NO blood will be taken and NO analysis of the blood analyte concentrations will
occur in this study.
