Clinical Medicine Exam 4
Hypersensitivity Pneumonitis
"Extrinsic allergic alveolitis" Pulmonary disease that occurs due to inhalational exposure to a variety of antigens leading to an inflammatory response of the alveoli and small airways "Nonatopic, nonasthmatic inflammatory pulmonary disease" Generally caused by the inhalation of organic dusts. This results in a T cell mediated hypersensitivity alveolitis. Acute phase prodrome - often resolves when exposure is eliminated.
FEV1
( Forced Expiratory Volume in One Second) The volume of air forcefully exhaled in One second from a maximal inhalation.
FVC
(Forced Vital Capacity) This is when a pt takes a full inhalation and then forcefully exhales all the volume of air they can get out.
FRC
(Functional Residual Capacity) This is the volume of air in the lungs at the end of a normal exhalation.
RV
(Residual Volume) At the end of a maximum exhalation this is the volume left over.

Blue bloater
What bloater is bronchitis prominent COPD? is a person where the primary underlying lung pathology is chronic bronchitis. Chronic bronchitis is caused by excessive mucus production with airway obstruction resulting from hyperplasia of mucus-producing glands, goblet cell metaplasia, and chronic inflammation around bronchi. Unlike emphysema, the pulmonary capillary bed is undamaged. Instead, the body responds to the increased obstruction by decreasing ventilation and increasing cardiac output. There is a dreadful ventilation to perfusion mismatch leading to hypoxemia and polycythemia. In addition, they also have increased carbon dioxide retention (hypercapnia). Because of increasing obstruction, their residual lung volume gradually increases (the "bloating" part). They are hypoxemic/cyanotic because they actually have worse hypoxemia than pink puffers and this manifests as bluish lips and faces.

What other treatment is done for COPD?
Pink puffer
What puffer is emphysema prominent COPD? emphysema is the primary underlying pathology. Emphysema results from destruction of the airways distal to the terminal bronchiole--which also includes the gradual destruction of the pulmonary capillary bed and thus decreased inability to oxygenate the blood. So, not only is there less surface area for gas exchange, there is also less vascular bed for gas exchange--but less ventilation-perfusion mismatch than blue bloaters. The body then has to compensate by hyperventilation (the "puffer" part). Their arterial blood gases (ABGs) actually are relatively normal because of this compensatory hyperventilation. Eventually, because of the low cardiac output, people afflicted with this disease develop muscle wasting and weight loss. They actually have less hypoxemia (compared to blue bloaters) and appear to have a "pink" complexion and hence "pink puffer". Some of the pink appearance may also be due to the work (use of neck and chest muscles) these folks put into just drawing a breath.

pH 7.4, glucose 90, protein 0.04 mg/dl, LDH Transudative or Exudative?
Exudative (protein over 0.5 and LDH over 0.6)
pH 7.4, glucose 90, protein 8 mg/dl, LDH 220 Transudative or Exudative?
Alkalosis Metabolic Uncompensated
pH 7.48 PaCO2 40 HCO3 28 PaO2 90 Acidosis or Alkalosis? Respiratory or Metabolic? Is it compensated?
Hering-Breuer reflex
protective reflex initiated by extreme overinflation of the lungs; initiates expiration
Simple Mask
ran between 5-8 L/M DO NOT RUN BELOW 5 L/M The less flow is not enough to flush CO2 from the mask. Delivers 30-55% FiO2 Great for patients that are mouth breathers
Voriconazole (Vfend)
reserved for serious refractory disease. What med is this for histoplasmosis?
Amphotericin B
reserved for severe or refractory disease due to its potential toxicity. What med is this for histoplasmosis treatment?
Medullary Respiratory Centers
responsible for respiratory rhythm nerve impulses travel along the phrenic and intercostal nerves to excite the diaphragm and external intercostal muscles respectively
Positive airway pressure
splints the upper airway open and is generally considered first-line therapy for OSA CPAP (continuous positive airway pressure) Delivers pos. airway pressure at a constant level It is used most often b/c it's the simplest, most studied and associated with the most clinical experience *Only about 75% of patients continue to use CPAP regularly > 1 year* Supplemental oxygen may be added for severe desaturations, but may lengthen apnea
Pneumotaxic Center (pons)
take deep breath and then stops it exerts inhibitory effects on the medulla
Right Axis Deviation
tall R waves in the right precordial leads (V1-V3), and deep S waves in the left precordials (V4-V6) What is this on EKG for PE?
P pulmonale
tall, narrow, peaked P waves usually in leads II, III and AVF What is this on EKG for PE
Surgery
treatment appears to be most effective in patients who have OSA due to severe, surgically correctable, obstructing lesion (i.e.: tonsillar hypertrophy) There is no consensus regarding the role of surgery in the absence of such a lesion Uvulopalatopharyngoplasty (UPPP) is the most common surgical procedure that is performed in this context
Bronchodilator Therapy
β Adrenergic agonists Albuterol short acting Salmeterol long acting Albuterol decreases the amount of damage occurring to the mucosal layer of the lungs. There is a significant amount of bronchodilation However, there is not significant evidence to show improvement long term in the FVC or FEV1 Both improve mucus transport in the lungs.
