This Concept Map, created with IHMC CmapTools, has information related to: Pulmonary Hypertension, COPD Interstitial fibrosis Obesity-hypoventilation Syndrome . Chronic hypoxemia, Pulmonary artery vasoconstriction . Increased pulmonary artery pressure, Chronic acidosis . Pulmonary artery vasoconstriction, 55 y/o Female Pulmonary Hypertension Defined Prolonged elevation of the mean pulmondary artery pressure (PAP) at or above 25mm Hg with a pulmonary capillary wedge pressure of 15 mm Hg or higher, both measured at rest., Right Heart Failure Nursing Dx Activity intolerance r/t imbalance between oxygen supply/demand AEB weakness, fatigue, and changes in vital signs., Captopril, Digoxin, Doxazosin, Nifedipine, Polyethylene glycol Increased urine output Chloride 99 BUN 32 Creatinine 1.3 Glucose 141, Right Heart Failure Medications Captopril, Digoxin, Doxazosin, Nifedipine, Polyethylene glycol, 55 y/o Female Pulmonary Hypertension Nursing Dx Risk for diarrhea r/t pharmacological therapy (opiates, narcotics, laxatives), Chronic hypoxemia Nursing Dx Impaired gas exchange r/t altered oxygen supply and alveoli destruction AEB abnormal ABG values, changes in vital signs, and reduced tolerance to activity., Chronic acidosis Abnormal ABGs pH blood 7.38 pO2 49 pCO2 58 Bicarb 34.3 O2sat 83, Chronic pulmonary hypertension . Cor Pulmonale (hypertrophy and dilation of right ventricle), Pulmonary artery vasoconstriction Medications Albuterol-ipratropium, Bosenton, Increased pulmonary artery pressure Progression of pulmonary hypertension can be reversed at this point with effective treatment of primary or underlying disease Intimal fibrosis and hypertrophy of medial smooth muscle layer of pulmonary arteries, pH blood 7.38 pO2 49 pCO2 58 Bicarb 34.3 O2sat 83 Lab results lead to Compensated Respiratory Acidosis, Chronic hypoxemia . Chronic acidosis, Cor Pulmonale (hypertrophy and dilation of right ventricle) . Right Heart Failure, Intimal fibrosis and hypertrophy of medial smooth muscle layer of pulmonary arteries . Chronic pulmonary hypertension, Captopril, Digoxin, Doxazosin, Nifedipine, Polyethylene glycol Possible Side Effect Risk for diarrhea r/t pharmacological therapy (opiates, narcotics, laxatives), 55 y/o Female Pulmonary Hypertension Starts with COPD Interstitial fibrosis Obesity-hypoventilation Syndrome
