The present application relates to the technical field of component detection, in particular to a
rapid detection system for
respiratory tract sputum components of severe patients based on
mass spectrometry. The
system can realize the following steps through the cooperation between multiple modules: obtaining a target
mass spectrum corresponding to a
respiratory tract sputum sample of a patient to be detected, and identifying a target characteristic peak and its corresponding
isotope peak cluster in the target
mass spectrum; determining a
pathogen compliance index,
protein flooding possibility and
isotope peak distribution rationality corresponding to each target characteristic peak; screening
protein flooding characteristic peaks from all target characteristic peaks; segmenting target
pathogen peaks from the
protein flooding characteristic peaks, and detecting
respiratory tract sputum components according to the target characteristic peaks and the segmented target
pathogen peaks. The present application realizes the segmentation of protein flooding characteristic peaks by analyzing the protein flooding condition in the characteristic peaks, thereby facilitating the identification of the flooded pathogen, and further improving the accuracy of respiratory tract sputum component detection.
