Objective:
This study aims to assess the latent profile characteristics of Chinese nurses' knowledge, attitudes, and practices regarding excessive oxygen therapy and explore the influencing factors of different profile types.
Methods:
From November to December 2025, convenience sampling was used to select nurses from secondary and tertiary general hospitals in Zunyi City, Guizhou Province, as the study participants. A self-designed demographic characteristics questionnaire and the Knowledge, Attitudes and Practice Scale of Healthcare Professionals on Excessive Oxygen Therapy (KAP-HPEOT) were used as survey tools. Latent profile analysis (LPA) was performed on the nurses' KAP regarding excessive oxygen therapy. Univariate analysis of factors influencing different profiles was performed using the chi-square test and ANOVA, and multivariate analysis was conducted using logistic regression.
Results:
A total of 743 questionnaires were collected, with 687 valid responses, yielding an effective response rate of 92.46%. Latent profile analysis revealed that nurses' knowledge, attitudes, and practices regarding excessive oxygen therapy could be categorized into three profile types: "Low Knowledge-Moderately Attitude-Moderate Practice" (19.65%), "Moderate Knowledge-Moderately Attitude-Moderate Practice" (20.23%), and "High Knowledge-Positive Attitude-High Practice" (60.12%). Logistic regression analysis indicated that age, work experience, professional title, education level, hospital level, participation in oxygen therapy training, and department were significant influencing factors of nurses' KAP regarding excessive oxygen therapy (P < 0.005).
Conclusion:
This study confirms that nurses' KAP regarding excessive oxygen therapy can be categorized into three profiles, and demographic-related characteristics significantly influence their KAP. The findings provide an important theoretical basis for nursing managers and educators to develop relevant training programs.

Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
