Question

PCO, (partial pressure of carbon dioxide) pO2 (partial pressure of oxygen) Hemoglobin - O, saturation [HCM] 40 mm Hg 90 - 100 mm Hg 94 - 100% 24 meq/liter Case study 1: A 14-year-old girl with cystic fibrosis has complained of an increased cough productive of green sputum over the last week. She also complained of being increasingly short of breath, and has sounds in her lungs on physical examination. Arterial blood was drawn and sampled, revealing the following values: pH pCO2 PO 7.30 50 mm Hg 55 mm Hg 45% 28 meq / liter Circle: High, Normal or Low Circle: High, Normal or Low Circle: High, Normal or Low Circle: High, Normal or Low Circle: High, Normal or Low Hemoglobin - O saturation [HCO3) Questions: 1. Briefly describe how cystic fibrosis affects the lungs? 2. What does green sputum" indicate? What "sounds in her lungs" would you expect this patient to have? 3. What type of acid-base disturbance does she have? 4.. Draw the acid-base equation and show (with arrows) the acid base imbalance.

Answer 1

o Cystic fibrosis is a genetic disease. Gf causes the mucus to become thick and sticky which germs cannot be filtered from lungs. This causes the lungs infections because bacteria becomes trapped. Which causes inflammation, infections, respiratory failure. in lungs. | Green sputum or phlegm indicates the presence of WBC, proteins, cells, gearms which are produced during the robust immune response chich this all give green colours This usually indicates the progression of illness from viral to bacterial (b) Rhonchi is a lowo pitched ratting lung sounds which we can expect from this patient. It often resemble sound of snore. © The patient have respiratory acidosis. Because the girl have lower pH than normal level.
