Diagnosis of carbon monoxide exposure in clinical research and practice: A scoping review.

ABSTRACT:

Objective

To undertake a scoping review to identify methods and diagnostic levels used in determining unintentional, non-fire related carbon monoxide exposure.

Design

Online databases and grey literature were searched from 1946 to 2023 identifying 80 papers where carbon monoxide levels were reported.

Results

80 papers were included; 71 research studies and 9 clinical guidelines. Four methods were described: blood carboxyhaemoglobin (arterial or venous blood analysis), carbon monoxide oximetry (SpO2), expired carbon monoxide, and ambient carbon monoxide sampling. Blood analysis methods predominated (60.0% of the papers). Multiple methods of measurement were used in 26 (32.5%) of the papers. Diagnostic levels for carboxyhaemoglobin were described in 54 (67.5%) papers, r
