The factor in Fick’s law that has caused the patient’s oxygenation status to acutely worsen in this case. Introduction: A 78–year-old woman is admitted to the hospital. She has a medical history of chronic interstitial lung disease, alveolar fibrosis, and thickening. Her X-ray reports were taken and they showed signs of higher alveolar density. When brought into the hospital, she was found agitated and anxious. Her respiration rate was noted as 24 breaths per minute and heart rate as 105 beats per minute. Please refer to Clinical Application Case-2 for further information.

Match the Law/Effect with its definition/description A. Boyle’s Law B. Henry’s Law C. Dalton’s Law D. Haldane Effect E. Bohr Effect 1. The pressure of a gas is inversely proportional to its volume 2. A lower, more acidic pH promotes oxygen dissociation from hemoglobin 3. Hemoglobin saturated with oxygen has a low affinity for carbon dioxide 4. The concentration of a gas in a liquid is directly proportional to the solubility and partial pressure of that gas 5. The total pressure exerted by a mixture of gases is the sum of the partial pressures of the gases in the mixture

Scenario three I was working evenings in the emergency department of a seaside hospital. We admitted a 54-year-old man, whom I'll call Mr. Schmidt. He told me, “I just got here for vacation, and I'm not feeling so great. I had pneumonia at home, got treated, and thought I was better. Now my breathing feels lousy again." A check of his vital signs while he was sitting quietly revealed the following: T 99° C, P 138 beats/min, R 36 breaths per minute, BP 168/80 mm Hg. As I helped him to the stretcher, he became significantly more short of breath. I checked his lung sounds and heard a lot of congestion. I notified the doctor and voiced my concern that Mr. Schmidt seemed quite ill. The doctor examined him and ordered an electrocardiograph and chest x-ray study. During this time we got very busy. I was helping another patient when the doctor came to me and said, "I want you to give Mr. Schmidt 80 mg of furosemide (a diuretic) IV now and discharge him." I looked at him skeptically and said,…

A common laboratory test for a patient is to measure blood gases—that is, the partial pressures of O 2 and CO 2 in oxygenated blood. Normal values are 100 mm Hg for O 2and 40 mm Hg for CO 2. A high or low level of one or both readings has some underlying cause. Offer an explanation for each of the following situations. a. If a patient comes in agitated and hyperventilating—breathing very rapidly—the partial pressure of O 2 is normal but the partial pressure of CO 2 is 22 mm Hg. b. A patient with chronic lung disease has a partial pressure of O 2 of 60 mm Hg and a partial pressure of CO 2of 60 mm Hg.
