Asthma-I: Introduction01:29

Asthma-I: Introduction

2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Adrenergic Agonists: Mixed-Action Agents01:28

Adrenergic Agonists: Mixed-Action Agents

701
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Assessment of Ventilation II: Respiratory Depth and Rhythm

1.5K
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:

Respiratory Assessment: Purpose and Indications

1.1K
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...

Area of Science:

  • Digital Health
  • Respiratory Medicine
  • Human-Computer Interaction

Background:

  • Asthma affects millions in the UK, with a significant gap in accessing basic care, leading to high mortality rates.
  • Chatbots offer a potential solution to extend asthma support and connect patients with healthcare services.

Purpose of the Study:

  • To evaluate 'Brisa', a chatbot designed to enhance self-assessment and self-management for asthma patients.
  • To assess the usability, effectiveness, and user satisfaction of the 'Brisa' chatbot.

Main Methods:

  • 150 adults with asthma used the 'Brisa' chatbot via WhatsApp or website for 28 days.
  • Evaluated user experience, asthma control, symptom tracking, interaction metrics, and qualitative feedback.

Main Results:

  • 74% of participants engaged with the chatbot, with high task completion rates for risk assessment (86%) and control tracking (95.5%).
  • An 8% improvement in asthma control was reported post-use, alongside positive user feedback on helpfulness, privacy, and functionality.
  • Areas for improvement included conversational depth and personalization.

Conclusions:

  • Chatbots are effective tools for asthma support, evidenced by high feature usage and improved asthma control.
  • User satisfaction indicates a need for more advanced conversational capabilities in health-focused chatbots.
  • Future chatbots must balance conversational fluency with accuracy and safety for sustained engagement and effectiveness.
