A.) How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? - Since Cari is a smoker, cigarette smoke has paralyzed her cilia and stimulated the goblet cells lining her respiratory passages to secrete excess amounts of mucus. Ducts from the sinuses open into the internal nose providing a passageway for microorganisms to travel into the sinuses. B.) What is the couch reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by couching. - A long drawn and deep inhalation followed by a complete closure of the glottis, which results in a strong exhalation that suddenly pushes the glottis open and sends a blast of air through the upper respiratory passages. Stimulus for this…show more content…
The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well. G.) How does the elevation of Cari’s respiratory rate alter her minute ventilation? - The higher her respiratory rate the more liters of oxygen needed to supply for the loss in her lungs. To get the minute ventilation you take the breaths per min times 500mL/breath and that gets your liters of oxygen per min. H.) How do the the clinical findings relate to the internal respirations in Cari’s body? - Cari’s po2 is 54 mm Hg so therefore her lungs were working as if she was doing intense exercise although she wasn’t. Decreased oxygen saturation and PO2, decrease the efficiency of gas exchange between the arterial blood and tissues of the body. I.) Which of the symptoms Cari’s has described are due to the lack of oxygen and reduced oxygen exchange in her tissues? - Cari’s states, “I feel like I’m panting like a dog, and my chest hurts” Her shortness of breath, fatigue and headache are all results of the lack of oxygen exchange to her tissues. The pH of her blood was rising due to the hyperventilation also. J.) As Cari’s Pco2 rose, how was the oxygen-carrying capacity of hemoglobin affected? - As Pco2 rises, hemoglobin releases O2 more readily. Pco2 and pH are related factors because low blood pH (acidity) results from high Pco2. K.) How would you have expected Cari’s decreased Pco2 and alkaline blood pH to have affected her
