Inhaled Medications

1.1K
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

COPD: Management Using Bronchodilators and Corticosteroids

1.2K
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Crossover Experiments01:16

Crossover Experiments

3.4K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Asthma I: Introduction01:28

Asthma I: Introduction

311
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma III: Clinical Manifestations

73
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

BreatheBuddy, a gamified training system, significantly improved children's asthma inhalation techniques and adherence. This innovative approach enhances treatment effectiveness and reduces anxiety in pediatric patients.

Area of Science:

  • Pediatric respiratory medicine
  • Human-computer interaction
  • Behavioral intervention

Background:

  • Asthma is a common childhood respiratory illness globally.
  • Inhalation therapy is standard treatment, but poor technique and adherence hinder effectiveness.
  • Novel interventions are crucial to improve pediatric asthma management.

Purpose of the Study:

  • To develop and evaluate BreatheBuddy, a gamified system for enhancing children's asthma inhalation skills and adherence.
  • To assess the impact of gamified feedback on inhalation accuracy, adherence, and user satisfaction.
  • To investigate BreatheBuddy's potential in reducing anxiety and improving focus during training.

Main Methods:

  • A single-factor repeated-measures design involving 20 children (6-8 years old) with prior inhaler experience.
Keywords:

  • Experimental group used BreatheBuddy with real-time animated feedback; control group used conventional methods.
  • Assessment via respiration sensor, Player Experience of Need Satisfaction, GUESS, and SUS scales.

    • Main Results:

    • The experimental group showed significant improvements in inhalation accuracy, breath-holding duration, and breathing stability (P<.001).
    • Higher engagement and motivation observed in the experimental group, with superior Player Experience of Need Satisfaction and GUESS scores.
    • Superior usability (SUS score=88.96) and reduced anxiety/improved focus reported in the BreatheBuddy group.

    Conclusions:

    • BreatheBuddy effectively optimizes inhalation skills, boosts adherence, and alleviates anxiety in children with asthma.
    • The system integrates breathing behaviors into core game mechanics, offering a novel approach to skill training and emotional regulation.
    • Provides empirical evidence for gamified interventions in pediatric respiratory care and a practical tool for clinical training.
