    Study Notes

    Respiratory Disorders Overview

    • Respiratory disease affects 1 in 5 people.
    • It's the 3rd largest cause of death in England.
    • 25% of patients may have a respiratory disorder.
    • Common causes of death include lung cancer, COPD, and pneumonia (NHS England).
    • Smoking is a significant risk factor, particularly in lower socioeconomic groups.
    • Dental professionals must understand how respiratory disorders impact oral health.

    Aims and Learning Objectives

    • Students will learn the anatomy and physiology of the respiratory system.
    • Students will understand pulmonary ventilation and perfusion.
    • Students will define respiratory disorders and identify types of lung diseases.
    • Students will study the pathophysiology of common respiratory conditions (e.g., asthma).
    • Students will learn how to manage respiratory emergencies.
    • Students will understand how dental treatments might be affected by these conditions.
    • Students will be able to identify and understand the relevance of medications patients may be taking.

    Structure of the Lecture

    • Part 1: Revision of respiratory system anatomy, physiology, ventilation, and perfusion.
    • Part 2: Explanation of respiratory diseases, classifications, common conditions, signs, symptoms, and treatments.
    • Part 3: Detailed study of asthma and COPD, including pathophysiology, signs, symptoms, and treatments.
    • Part 4: Management of dental patients with respiratory diseases, and addressing clinical considerations, smoking, prevention, and medical emergencies.
    • Group discussion and MCQs: Reflective learning and assessment of understanding.

    Anatomy and Physiology of the Respiratory System

    • The respiratory system includes the trachea, bronchi, bronchioles, alveoli, and lungs.

    • Crucial functions like ventilation (breathing) and perfusion (oxygen exchange) are covered.

    Respiratory Disease Classifications

    • Respiratory diseases are categorized into airway diseases, lung tissue diseases, and lung circulation diseases.

    • Airway diseases include asthma and COPD, involving airway narrowing and inflammation.

    • Lung tissue diseases like tuberculosis and COVID-19 damage lung tissue, affecting expansion and breathing.

    • Lung circulation diseases like pulmonary hypertension impact blood vessel function around the lungs.

    Common Lung Diseases (Examples)

    • Asthma: A common chronic inflammatory condition affecting the airways, leading to wheezing, coughing, chest tightness, and shortness of breath.
    • COPD: A progressive lung disease (chronic bronchitis and emphysema), impacting the ability to breathe air out of the lungs.
    • Lung Cancer: A significant cause of death, often linked to smoking, with persistent cough, pain, coughing up blood, breathlessness, weight loss, and fatigue.
    • Pneumonia: Inflammation of lung tissue, with symptoms like cough, trouble breathing, fever, sweating, and loss of appetite.
    • Pleural Effusion: Fluid buildup around the lungs, causing problems with breathing and often related to other diseases.

    COPD: Key Points

    • COPD (Chronic Obstructive Pulmonary Disease) comprises chronic bronchitis and emphysema.
    • Smoking is a major factor in the development of COPD.
    • Prevalence increases with age (often diagnosed over age 50).
    • There are estimated 3 million people with COPD in the UK (2 million undiagnosed).

    Asthma: Key Points

    • Asthma affects people of all ages and is a common chronic inflammatory disorder of the airways.
    • Triggers can include allergens, stress, occupational exposure, and environmental factors.
    • Symptoms include wheezing, coughing, tightness in the chest, and shortness of breath and may lead to acute asthma attacks.
    • Medications can treat asthma symptoms.

    COPD Management

    • COPD management emphasizes prevention (stop smoking, vaccinations).
    • Treatment involves exercise programs and managing any coexisting health issues.
    • Medications can relieve breathlessness and help prevent exacerbations.
    • Oxygen therapy might be required in severe cases.

    Asthma - Medical Emergency

    • Asthma symptoms to watch for:

    • Breathlessness, expiratory wheezing

    • Severe inability to speak full sentences

    • RR (respiratory rate) > 25/min and Pulse >110/min

    • Life-threatening symptoms: cyanosis RR <8/min Pulse <50/min, exhaustion, confusion and decreased LOC

    • Asthma attack management: ABCDE.

    • Sit the patient upright.

    • Give 2 puffs of 100mcg bronchodilator inhaler.

    • Oxygen 15L/min and bronchodilator, via spacer if possible.

    • Supportive care with a senior colleague if necessary.

    Dental Management of Patients with Asthma

    • When was the patient diagnosed?
    • What medications are they taking?
    • Has the patient experienced hospitalizations related to their asthma?
    • What triggers their asthma attacks?
    • Are there any other allergies?

    Dental Management of Patients with COPD

    • Get a full medical history (including medications, triggers, disease severity, hospital admissions, and oxygen use).
    • Determine smoking status; offer cessation resources if applicable.
    • In invasive procedures: monitor SpO2/SATS during and after the procedure as needed.
    • If SpO2 is low, consult senior staff for support and possible oxygen administration.

    Medical Emergencies

    • Patient could collapse at any time, regardless of prior treatment.
    • Training and awareness of medical emergencies, including resuscitation, are crucial for all dental staff.
    • Plan ahead, using a multi-professional medical approach.
    • Take a full, accurate patient medical history.
