Abstract:
Objective:To explore the risk stratification of pulse oxygen saturation (SpO2) in patients with emergency hypoxemia patients, and to provide evidence for the identification of critical illness.
Methods:Self-designed clinical data registration form for patients with emergency hypoxemia, and prospective collection of 344 hypoxemia patients in the emergency department of Peking Union Medical College Hospital from March to April in 2018, including baseline data (name, gender, age, ID number, date, registration time), hospitalization method, past history, patient complaint and diagnosis, triage level, SpO2, whether to enter the rescue room, etc.
Results:All of 344 emergency hypoxemia patients, there were 163 cases (21.2%) of ambulances, and 107 cases (31.1%) of patients requiring immediate rescue. There were 54 cases (25.7%) and 53 cases (39.6%) in need of immediate rescue in day shift (8:00-20:00) and night shift (20:00-8:00 next day), with 9:00-10:00, 14:00-15:00, 20:00-24:00 in the majority. There was a statistical difference in the way of hospitalization, triage, and SpO2 (χ2=29.537, 25.780, t=4.722, all P<0.05) . SpO2 risk stratification was 0.905 in patients without pulmonary disease, and SpO2 risk stratification in patients with lung disease was 0.765.
Conclusions:Patients with hypoxemia account for a certain proportion in the emergency department and are in critical condition. The degree of critical condition of patients can be evaluated based on whether they have lung diseases, and the risk stratification of patients can be accurately determined with the help of SpO2, so as to further guide the hierarchical treatment measures for patients with emergency hypoxemia and rationally optimize the allocation of emergency resources.
