Summary
This study maps deep-breathing exercises (DBE) research, revealing key themes in education, cardiac surgery, and postoperative care. Findings highlight collaboration gaps and future research priorities for perianesthesia nursing.
Area of Science:
- Bibliometrics and Topic Modeling
- Medical Research Analysis
- Perianesthesia Nursing
Background:
- Deep-breathing exercises (DBE) are increasingly studied for various applications.
- Understanding the research landscape is crucial for guiding future investigations.
- A systematic mapping of DBE research is needed to identify trends and gaps.
Purpose of the Study:
- To systematically map the intellectual structure of deep-breathing exercises (DBE) research.
- To analyze the thematic evolution and collaborative patterns in DBE studies.
- To identify dominant research themes and potential areas for future investigation.
Main Methods:
- Bibliometric analysis of 2,017 publications (1940-2024) from Web of Science, Scopus, and PubMed.
- Latent Dirichlet Allocation (LDA) topic modeling to identify dominant research themes.
- Analysis of publication trends, leading journals, authors, countries, and collaboration networks.
Main Results:
- Publication numbers steadily increased, peaking in 2020, with the US, Italy, and Germany as leading countries.
- Limited international and interinstitutional collaboration was observed.
- Three main themes emerged: DBE in education/training, post-cardiac/thoracic surgery application, and postoperative complication prevention/rehabilitation.
Conclusions:
- Bibliometric and topic modeling analysis provides a structured overview of DBE research in surgical and perioperative care.
- Findings highlight research priorities, collaboration gaps, and underexplored areas, rather than clinical effectiveness.
- Insights can inform future research agendas, encourage interdisciplinary collaboration, and guide strategic development in DBE studies for perianesthesia nursing.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
2.8K
Respiratory Depth
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:

50.4K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

1.2K
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

01:30Alterations in Respiration II
2.5K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Introduction
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...

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
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...
