    Study Notes

    Oxygen Therapy Recommendations

    • Transition to a cannula at 2 L/min for more effective oxygen delivery.
    • Minimum flow of 5 L/min recommended to effectively wash out exhaled CO₂.

    Diaphragm Resilience

    • Contains mostly Type II A fibers, aiding in endurance.
    • More than half of its fibers are slow oxidative, which provides resistance to fatigue.

    Arterial Blood Pressure Assessment

    • The radial artery is the most commonly used site for assessing arterial blood pressure.

    Breathing Pattern Abnormalities

    • Abdominal paradox indicates diaphragmatic fatigue.
    • Breathing patterns associated with various lung diseases: restrictive vs. obstructive.

    Types of Chest Pain

    • Pleuritic pain: sharp, worsens with breathing.
    • Muscular pain: related to muscle strain or inflammation.
    • Costochondral pain: tenderness at rib junctions.
    • Intercostal neuritis pain: caused by nerve irritation.
    • Pericardial pain: associated with heart conditions.
    • Aortic pain: often radiates to the back, signifies serious conditions.
    • Myocardial pain: a hallmark of heart attacks, presents as pressure or tightness.

    Variables of Chest Pain (LIQOR)

    • Location: where the pain is felt.
    • Intensity: severity of the pain.
    • Quality: descriptive nature (sharp, dull, throbbing).
    • Onset: when the pain started.
    • Relief: factors that alleviate the pain.

    Sputum Characteristics

    • Analyzing sputum can help diagnose respiratory disorders based on color, consistency, and odor.

    Physical Assessment – Inspection Phase

    • First phase of physical assessment, focuses on visual evaluation of the patient.

    Cyanosis

    • Central cyanosis indicates systemic issues; peripheral cyanosis suggests localized problems.

    Thoracic Deformities & Clinical Implications

    • Barrel chest: often seen in COPD.
    • Kyphosis: can affect lung function and breathing.
    • Scoliosis: can lead to asymmetrical lung expansion.
    • Pectus carinatum: may compress lungs.
    • Pectus excavatum: impacts lung capacity; observed in congenital conditions.
    • Gibbus deformity: indicates severe vertebrae deformities.
    • Dhal’s sign: associated with respiratory compromise.

    Digital Clubbing

    • Indicative of chronic hypoxemia; can signal underlying pulmonary or systemic diseases.

    Vital Signs Assessment

    • Essential to verify heart rate, respiratory rate, blood pressure, and temperature.

    Body Temperature & Fever

    • Fever types and causes should be understood for accurate diagnosis.

    Lung Compliance & Fibrosis

    • A fibrotic lung exhibits decreased compliance and increased stiffness.

    Alveolar Gas Equation

    • Requires accounting for water vapor pressure to calculate PAO₂ accurately.

    Hemoglobin & Oxygen Affinity

    • Increased temperature decreases hemoglobin's affinity for oxygen, facilitating oxygen release to tissues.

    Breath Sound Characteristics

    • Normal sounds: tracheal, bronchial, bronchovesicular, and vesicular.
    • Abnormal sounds may indicate pathologies; characterized by varying pitch and amplitude.

    Clinical Signs of Respiratory Distress

    • Retraction indicates increased work of breathing.
    • Digital clubbing and its correlation with lung disease.

    Assessment Techniques

    • Palpation: feel for abnormalities.
    • Percussion: identifies fluid, air, or solid mass in lungs.
    • Auscultation: using a stethoscope for listening to heart and lung sounds.

    Oxygenation in Chronic Lung Disease

    • SaO₂ levels and their interpretation in patients with hypoxemia.

    Smoking History Calculation

    • Pack-years is calculated by multiplying the number of packs per day by the number of years smoked.

    Pulsus Paradoxus

    • Associated with significant changes in pulse during breathing, commonly seen in severe asthma.

    Capillary Refill Test

    • Demonstrates vascular health; delayed refill indicates circulatory issues.
