Background:
Oral care is critical for preventing ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients. ICU nurses play a key role in delivering this care but often encounter challenges stemming from knowledge gaps and inconsistent practices.
Aim:
To assess ICU nurses' knowledge, attitudes and practices (KAP) in oral care for VAP prevention and identify demographic factors influencing these variations using random forest analysis.
Study Design:
A multi-centre cross-sectional study was conducted. Between April and June 2023, 291 ICU nurses from five ICUs across three public tertiary hospitals in Ganzhou City were surveyed using proportionate stratified sampling. Likert-scale questionnaires evaluated KAP, and statistical analyses, including t-tests, analysis of variance and random forest models, were used to determine demographic predictors of KAP scores.
Results:
The average KAP scores were as follows: knowledge 27.34 (±4.53), attitudes 31.89 (±4.24), and practices 43.13 (±9.0). Significant predictors of KAP included academic titles, professional positions, gender, ICU tenure and department. Common barriers to effective oral care included lack of formal training, time constraints and limited resources.
Conclusions:
ICU nurses demonstrate positive attitudes towards VAP prevention, but significant gaps in knowledge and practice remain. Targeted education, especially for less-experienced and lower qualified nurses, and standardized protocols are essential to improve adherence to oral care practices and reduce VAP incidence.
Relevance To Clinical Practice:
The findings highlight the need for tailored educational interventions to address knowledge gaps, particularly among male, less-experienced and lower qualified nurses. Implementing standardized training protocols can enhance oral care practices, improve patient outcomes and reduce VAP incidence.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
