- A 50-year-old female patient has an FEV1 of 1.8 liters and an FVC of 3.2 liters. What is the patient's FEV1/FVC ratio, and what does it suggest about the patient's lung function? 0.39, severe obstruction O 0.56, moderate obstruction 0.69, mild obstruction O 0.78, normal lung functionGiven the following ABG (arterial blood gas) values for an asthmatic patient, what is your diagnosis? Briefly explain how you came to that diagnosis. pH = 7.33 (normal range: 7.38-7.42 PaCO2 = 55 mm Hg (normal range: 38-42 mm Hg) HCO3– = 25 mEq/L (normal range: 22-28 mEq/L) PaO2 = 70 mm Hg (normal range: 75-100 mm Hg)103) Emphysema is an obstructive type of disorder that results in a person having normal lung volumes but decreased forced expiratory reserve rates Group of answer choices True False 104) The Bohr Effect says that O2 is more easily released from hemoglobin as more H+ ions bind to the hemoglobin molecule. Group of answer choices True False 105) When you have very low levels of carbon dioxide in the blood due to hypocapnia or hyperventilation, the immediate affect is a decrease in the breathing rate Group of answer choices True False 106) Decreased blood pressure results in a decrease of the heart rate. Group of answer choices False True
- How can the ideal gas law be applied in health sciences?Using the following lung volumes, calculate this persons FEV1 / FVC ratio. What this person's pulmonary function be clinically classified: normal, obstructive, or restricted? TLC = 5.2 L FVC = 3.8 TV = 0.5 L ERV = 1.1 L IRV = 2.2 L This person forcefully expired 2.4 L in one second. according to reference material, normal VC for this person is 3.6 L.The administration of oxygen at increased ambient pressures is now being used routinely to treat a variety of pathologic conditions. True or false?

What shift in the O2 - Hemoglobin curve occurs due to carboxyhemoglobin? Provide at least 3 clinical manifestations of carbon monoxide poisoningThere is a theory that suggests a patient with COPD might have a depression of ventilation following administration of high fiO2. Which of the following best summarizes the recommendations on how to address this concern? A. Never administer supplemental oxygen to patients with COPD as the risk of them stopping breathing is too great B. Treat acute hypoxemia with oxygen, but wean the oxygen as soon as possible C. Always double filter oxygen being delivered to a patient with COPD to ensure there are no particles that may be breathed in D. Supplement oxygen therapy with medical grade carbon dioxide to maintain dr to breatheMatch 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
