Cari’s Story
Question A: How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? The infection will spread into her sinuses because the pharynx, sinuses, larynx, and trachea are all connected and the infection is prone to spread to the surrounding areas if not treated in a timely manner.
Question B: What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. The cough reflex is a long and deep inhalation followed by the closing of the glottis, this causes a strong exhalation that pushes the glottis open and sends air through the respiratory passages. Stimulus for the reflex

Cari’s total lung capacity would be affected because the fluid buildup is not allowing the oxygen to get through the lungs.
Question G: How does the elevation of Cari’s respiratory rate alter her minute ventilation? Increasing her respiratory rate will increase the minute ventilation; this means Cari is taking in more breaths than needed causing her to hyperventilate (taking in more oxygen) and in turn cause hypocapnia (too little carbon dioxide). This will cause her blood gas levels to become unbalance and her body to become a hostile environment.
Question H: Normal blood oxygen saturation levels are great than 94%; Cari’s blood oxygen saturation level was 90% at the time of her exam and an initial arterial blood gas analysis done when she was admitted to the hospital revealed her arterial PO2 was 54mm Hg. How do these clinical findings relate to the internal respiration in Cari’s body? Because normal ranges of PO2 should be between 80-100 mm Hg and a normal O2 saturation level should be above 94% this means that the body is experiencing an unbalanced blood gas level and is becoming acidic. Internal respiration is the gas exchange between tissues in the body; this is not working properly causing the body to experience ketoacidosis.
Question I: Which of the symptoms Cari’s has described are due to lack of oxygen and reduce oxygen exchange at her tissues? Cari’s symptoms that are related to lack of oxygen are
