Study Notes
Introduction to the Respiratory System
- The respiratory system's function is to supply oxygen to the blood and remove carbon dioxide.
- It maintains the balance of oxygen and carbon dioxide in the body.
- The main organs of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, and lungs.
Combining Forms in Respiratory Terminology
- Pulmon/o, Pneum/o, Pneumon/o: Relates to the lungs.
- Pulmonology: The study of lung diseases.
- Pneumonia: Lung inflammation caused by infection.
- Bronch/o, Bronchi/o: Refers to the bronchial tubes.
- Bronchoscopy: Examining the bronchi visually.
- Bronchitis: Bronchial inflammation.
- Trache/o: Relates to the trachea (windpipe).
- Tracheotomy: Surgical opening into the trachea.
- Thorac/o: Refers to the chest.
- Thoracotomy: Surgical incision into the chest.
Prefixes in Respiratory Terminology
- Tachy-: Fast (e.g., tachypnea - rapid breathing).
- Brady-: Slow (e.g., bradypnea - slow breathing).
- Dys-: Difficult or painful (e.g., dyspnea - difficulty breathing).
- A- or An-: Absence of or without (e.g., apnea - temporary cessation of breathing).
Suffixes in Respiratory Terminology
- -pnea: Refers to breathing (e.g., eupnea - normal breathing, hyperpnea - increased breathing rate and depth).
- -oxia: Refers to oxygen (e.g., hypoxia - low oxygen levels, anoxia - absence of oxygen).
- -thorax: Refers to the chest cavity (e.g., pneumothorax - air in the chest cavity causing lung collapse).
- -itis: Refers to inflammation (e.g., rhinitis - inflammation of the nasal mucous membranes).
Common Respiratory Conditions
- Asthma: Chronic airway inflammation and narrowing causing wheezing and shortness of breath.
- Chronic Obstructive Pulmonary Disease (COPD): Progressive lung disease obstructing airflow.
- Emphysema: A form of COPD damaging the alveoli (air sacs) in the lungs.
- Pneumonia: Alveoli inflammation due to infection.
- Tuberculosis (TB): Bacterial lung infection.
Respiratory System Diagnostic Procedures
- Spirometry: Measures lung function and airflow by measuring the volume of air exhaled.
- Chest X-ray: Examines the lungs and chest cavity.
- Bronchoscopy: Visualizes the inside of the airways.
- Pulse Oximetry: Measures oxygen saturation in the blood.
Medical Terminology Related to Respiratory Disorders
- Bronchiectasis: Chronic dilation of the bronchi.
- Pleurodynia: Pain in the pleura (lining of the lungs).
- Hemoptysis: Coughing up blood.
- Orthopnea: Difficulty breathing while lying down.
- Pleuritis: Inflammation of the pleura.
Respiratory Treatments
- Inhalers: Deliver medication to the lungs for conditions like asthma and COPD.
- Nebulizer Therapy: Converts liquid medication into a mist for easier inhalation.
- Ventilation Support: Use of ventilators to assist or replace breathing.
Case Study (Patient John)
- Presenting Symptoms: Difficulty breathing, persistent cough, occasional chest tightness (for 2 months). Fatigue and shortness of breath, especially with exertion/climbing stairs.
- History of Present Illness: Increasing dyspnea (difficulty breathing) over the past few months, especially during physical exertion. Chronic productive cough with thick yellow sputum. 20-year history of smoking one pack per day.
- Wheezing and Tachypnea: Experiences wheezing (whistling sounds) and tachypnea (rapid breathing).
- Physical Examination: Respiratory rate: 26 breaths per minute (tachypnea). Oxygen saturation: 88% (hypoxia). Lung auscultation: Wheezing and crackles heard in lower lobes.
- Chest X-ray: Hyperinflated lungs with evidence of bronchiectasis and emphysema.
- Diagnostic Procedures: Spirometry revealed reduced forced expiratory volume (FEV1), confirming COPD. Pulse oximetry showed low blood oxygen levels. Sputum culture was negative for infections, ruling out pneumonia.
- Diagnosis: Chronic Obstructive Pulmonary Disease (COPD) with coexisting chronic bronchitis and emphysema.
- Treatment Plan: Smoking cessation program, bronchodilators, inhaled corticosteroids, oxygen therapy, and pulmonary rehabilitation.
