No results posted yet for this study

Summary

The RAD-57 pulse CO-oximeter is a lightweight device allowing non-invasive measurement of blood carboxyhemoglobin. Previous studies comparing RAD-57 measurements (SpCO) to standard laboratory blood gas analysis (COHb) have reported contradictory results.

the RAD-57 pulse CO-oximeter could be useful as a first-line screening test for acute CO poisoning, enabling rapid detection and management of patients with suspected CO poisoning in the prehospital emergency setting This study assesses the diagnostic value of pulse CO-oximetry, comparing SpCO to standard laboratory blood measurement for prehospital management of patients with suspected carbon monoxide (CO) poisoning.

Conditions

  • Carbon Monoxide Poisoning

Interventions

DEVICE

RAD57 measurement (SpCO)

SpCO measurement (Experimental) Non invasive pulse CO-oximetry will be carried out by prehospital emergency nursing staff trained in the use of the Rad-57 pulse CO-oximeter (Masimo, Inc., Irvine, CA, USA), using the adult sized sensor (Sensor, Rev. B) placed on the 3rd or 4th digit, according to manufacturer recommendations. Nail polish will be removed if necessary. SpCO was expressed in total percentage of hemoglobin.

DEVICE

CO-oximeter

COHb measurement (Active Comparator) Venous blood will be collected into EDTA treated tubes (Beckton Dickinson) prehospitally and sent to the toxicology laboratory for further carboxyhemoglobin testing. Blood carboxyhemoglobin will be analyzed by derivative spectrophotometry using an automated CO-oximeter (IL 682, Instrumentation Laboratory SpA V.le Monza 338-20128 Milan, Italy). Blood carboxyhemoglobin will be detected within a range of 0-100% and accuracy of 0.5% and reported as percentage of total haemoglobin.
