    Study Notes

    Pulmonary Circulation

    • Pulmonary Artery: Major vessel transporting deoxygenated blood from the right ventricle to the lungs for oxygenation.

    Breathing Mechanics

    • Inhalation: Process of drawing air into the lungs, also known as inspiration.
    • Exhalation: Act of releasing air from the lungs, referred to as expiration.
    • Ventilation: General movement of air into and out of the lungs.

    Gas Exchange

    • External Respiration: Exchange of oxygen and carbon dioxide in the lungs; crucial for the perfusion process.
    • Internal Respiration: Oxygen and carbon dioxide exchange at the cellular level, where blood delivers oxygen to tissues.

    Oxygen and Carbon Dioxide

    • Oxygen (O2): Essential for cellular energy production, absorbed by blood in lung air sacs.
    • Carbon Dioxide (CO2): Waste product of metabolism, removed from cells by the blood and expelled by the lungs.

    Vital Signs

    • Respiratory Rate: Measurement of breaths per minute, indicative of respiratory function.
    • Newborn Respiratory Rate: 30-60 breaths/min.
    • 1-Year-Old Rate: 18-30 breaths/min.
    • 16-Year-Old Rate: 16-20 breaths/min.
    • Adult Rate: 12-20 breaths/min.

    Respiratory Conditions

    • Bronchitis: Inflammation of the bronchial tubes, often occurring after viral infections.
    • Asthma: Condition leading to bronchial constriction and breathing difficulties, often triggered by allergens, treated with inhalers.
    • Emphysema: Lung disease characterized by alveolar wall destruction, often linked to smoking.
    • Chronic Obstructive Pulmonary Disease (COPD): Progressive condition limiting airflow, often resulting from asthma or emphysema.
    • Pneumonia: Lung inflammation due to infection, causing fluid in alveoli and symptoms of hypoxia.

    Diagnostic and Treatment Tools

    • Bronchoscope: Tool used to visualize the bronchial tubes.
    • Oximeter: Device measuring blood oxygen levels; normal values are around 100%.
    • Ventilator: Equipment providing mechanical breathing support for patients unable to breathe adequately.

    Abnormal Breathing Patterns

    • Apnea: Temporary cessation of breathing.
    • Tachypnea: Rapid breathing rate.
    • Bradypnea: Slow breathing.
    • Dyspnea: Difficult or labored breathing.
    • Orthopnea: Discomfort in breathing while lying flat, requiring the patient to sit upright.

    Physical Symptoms

    • Cyanosis: Bluish skin color from oxygen deficiency and carbon dioxide excess.
    • Hemoptysis: Coughing up blood.

    Surgical and Emergency Procedures

    • Pleurocentesis: Procedure to remove fluid from the pleural cavity for diagnostic purposes.
    • Tracheostomy: Surgical creation of an opening in the trachea to facilitate breathing, particularly in emergencies.

    Anatomical Structures

    • Nasal Septum: Structure dividing the nasal cavity.
    • Nares: External openings (nostrils) of the nasal cavity.
    • Cilia: Hair-like structures in the nasal cavity and airways aiding in trapping pathogens.

    Medications

    • Antihistamines: Block histamine effects to alleviate allergic reactions.
    • Bronchodilators: Medications relaxing bronchial muscles, commonly used for asthma management.
    • Corticosteroids: Reduce inflammation within the respiratory tract.

    Pathology and Conditions

    • Pneumothorax: Presence of air in the pleural space causing lung collapse.
    • Aspiration: Inhalation of food or foreign objects into the airways, or withdrawing fluid from a cavity for diagnosis.
    • Croup: Pediatric respiratory condition presenting with barky cough and stridor.

    Important Respiratory Terms

    • Rales: Abnormal, crackling lung sounds indicating moisture in the airways.
    • Rhonchi: Musical sounds during breathing, associated with bronchial spasms.
    • Stridor: High-pitched sound indicating airway obstruction, often seen in croup cases.
