Study Notes

Respiratory Disorders Overview

Respiratory disease affects 1 in 5 people, and is the 3rd largest cause of death in England.
25% of patients may suffer from respiratory disorders.
Lung cancer, COPD, and pneumonia are major causes of death.
Smoking is a significant risk factor, particularly prevalent among low socioeconomic groups.
Dental professionals need to understand how respiratory disorders impact oral health.

Aims & Learning Objectives

Explain the various parts of the respiratory system
Describe pulmonary ventilation and perfusion.
Define respiratory disorders and identify the different types of lung diseases.
Explain the pathophysiology of common respiratory disorders like asthma
Outline how to manage respiratory medical emergencies.
Explain how dental treatments can be affected by respiratory conditions and medications.
Describe medications patients with respiratory conditions might take and their role in dentistry.

Structure of the Lecture

Part 1: How the respiratory system works (revision) — covers anatomy, physiology, ventilation, and perfusion.
Part 2: How respiratory disease occurs — delves into classifications, common lung conditions, symptoms, and treatments.
Part 3: Asthma and COPD — discusses pathophysiology, signs, symptoms, and treatments for these conditions.
Part 4: Dental patient management with respiratory disorders — focuses on patient management, clinical considerations, smoking and prevention, medical emergencies for lung conditions.

Anatomy & Physiology of the Respiratory System

Diagram of respiratory system components (including trachea, primary, lobar, and segmental bronchi, superior/middle/inferior lobes, cardiac notch, lungs) is provided.
Diagram of pulmonary arteries and veins.
Four main parts of the respiratory system: the airway, the lungs, the muscles of respiration, and the blood vessels.
Respiratory system function involves breathing air in and out and receiving oxygen to cells.

Alveoli

Tiny air sacs in the lungs where gas exchange occurs.
A diagram shows the alveoli, alveolar sacs, pulmonary artery, and pulmonary vein, where the air exchange occurs.

Respiratory Tract

Parts of the upper respiratory tract, including nasal cavity, pharynx, and larynx.
Parts of the lower respiratory tract, including trachea, primary bronchi, and lungs .

Ventilation

Movement of air into and out of the lungs. Diagrams depict the process of breathing in and breathing out, detailing the role of ribs and diaphragm. Increased/decreased volume/pressure.

Perfusion

Process of moving oxygen into the blood vessels and removing carbon dioxide from blood vessels, also explained in a diagram.
Gas exchange process in the lungs between alveoli and pulmonary capillaries.

Common Lung Diseases

Diseases such as asthma, COPD (chronic obstructive pulmonary disease), chronic bronchitis, emphysema, lung cancer, pneumonia, and pleural effusion.
COPD is classified into airway diseases, lung tissue disease, and lung circulation disease.

Asthma: Key Points

A chronic inflammatory condition affecting airways (12% people in UK affected)
Symptoms like wheezing, coughing, tight chest, and shortness of breath.
Triggers include allergens, stress, workplace exposure, viruses, cold air, and exercise.
No cure, but medications can treat and prevent symptoms.
Acute asthma attack = worsening symptoms.

COPD: Key Points

Chronic lung disease causing narrowed/damaged airways.
Common causes include chronic bronchitis and emphysema.
Difficulty expelling air from lungs.
Prevalence increases with age, with diagnosis typically occurring after 50.
Smoking is a major risk factor.

Bronchitis:

Inflammation and narrowing of airways.
Excessive mucus production.

Emphysema:

Affects the alveoli (air sacs) leading to damage and breakdown.
Prevents effective air intake and output.

COPD Management

Prevention (stop smoking programs, vaccinations).
Exercise programs.
Individualized management plans addressing overall health and comorbidities.
Medications to treat breathlessness and prevent exacerbations.
Further care, such as oxygen therapy, for severe cases.

Asthma - Medical Emergency

Symptoms: breathlessness, expiratory wheeze, severe symptoms (inability to complete sentences, RR>25/min, Pulse>110/min).
Life-threatening symptoms include cyanosis, RR <8/min, Pulse <50/min, exhaustion, confusion, decreased level of consciousness (LOC).
Management: ABCDE (airway, breathing, circulation, disability, exposure).
Treat with appropriate asthma medication (inhaler – 2 puffs 100mcg bronchodilator)
Additional oxygen, further medical intervention as necessary.
Adrenaline doses

Anaphylaxis

Sudden onset, flushing, respiratory distress, hypotension, tachycardia.
Rapid progression, skin/mucosal changes, sense of impending doom.
Management: ABCDE, emergency services, lie down/elevate legs, oxygen (15L/min), adrenaline IM.
Detailed adrenaline dosing is provided (adult and pediatric).

Dental Management of Asthma and COPD Patients

Collect patient history details (diagnosis date, medication types/dosage, hospitalizations, triggers, other allergies, smoking history).
Understand severity of condition.
Identify suitable dental materials/tools.
Advice of triggers to avoid.
