Restrictive and Obstructive Pulmonary Disorders  Tell me what you know: ◈ Lungs anatomy- upper airway- lower airway right side of the heart ◈ Oxygenation Obstructiv Obstructive Increased resistance to Restrictive Reduced expansion of e and airflow lung tissue, decreased total lung capacity Restrictive Pulmonar Asthma Pulmonary fibrosis COPD Pneumoconiosis y Bronchiectasis Thoracic cage deformities Disorders: Sleep-disordered Overview breathing  Pulmonary Function: Overview Factor Characteristic Smoking Primary risk factor for some lung disease including secondhand smoke Occupational/Environmental Increase risk for some lung diseases exposure Bronchodilation Bronchioles dilate, increase airflow SNS: Beta-2 adrenergic receptors Bronchoconstriction Bronchiole smooth muscle constricts Reduced airflow PNS Leukotrienes/Histamine Released by WBCs Bronchoconstriction Compliance Flexibility of lungs Pleural membrane Lines chest cavity, envelops lungs  Lack of oxygen Hypoxemi Hypoxia: a: Lack of oxygen in bloodstre am Hypoxia and Hypercapni Elevated carbon a: dioxide Hypercapni levels a May Hypoxia occur together and Lungs cannot hypercapni exchange adequate a oxygen or carbon dioxide  Chronic Hypercapnia and Chronic Hypoxia Chronic Hypercapnia Chronic Hypoxia PaCO2 greater than 45 mm Hg Ideal PaO2: 90 to 100 mm Hg Headache, drowsiness, intellectual Mild hypoxemia: Few symptoms impairment Central chemoreceptors become PO2
