Objective:
To develop a supportive care needs questionnaire for patients with COPD and respiratory failure who are on a noninvasive ventilator, and to test its reliability and validity.
Methods:
The questionnaire was based on the short form of the Supportive Care Needs Scale. Its dimensions and items were formulated through literature analysis, semi-structured interviews, the Delphi method, and group discussions, resulting in the initial draft. The reliability and validity of the questionnaire were then evaluated.
Results:
The authority coefficients from two rounds of expert consultation were 0.875 and 0.888, with entry variation coefficients ranging from 0.05 to 0.42 and 0.05-0.21. Kendall's W-values were 0.551 and 0.487 (P < 0.05). Exploratory factor analysis identified five factors with 32 items, explaining 82.523 % of the variance. The content validity index S-CVI/Ave was 0.92, while S-CVI was 0.91. The total Cronbach's alpha coefficient was 0.982, with individual dimensions ranging from 0.924 to 0.976, and a test-retest reliability coefficient of 0.912.
Conclusion:
The developed questionnaire for assessing supportive care needs in COPD patients with respiratory failure using noninvasive ventilation demonstrates good reliability and validity, making it a suitable assessment tool.

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...
01:29Assessment 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:

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.
