Unit 5 Case Study 1: Cari’s story
1. How could an infection in Cari’s nasal passages and pharynx spread into her lungs?
That infection that was in the pharynx and is the nasal passages spread into the sinuses because that is where it should be draining for the nasal passages. (Tortora, 2013)
2. What is a cough reflex? Describe that process that Cari’s respiratory system is using to clear her lungs by coughing?
When you cough it clears sputum and other particles that are not supposed to be there. When there is too much mucus your body wants it out so it starts a coughing reflex. (Tortora, 2013)
3. Which structures found in the terminal bronchioles and alveoli normally would …show more content…
The minute ventilation is defining by the times in the respiratory rate by the total ventilation. (Tortora G. W., 2013)
8. Normal blood oxygen saturation levels are greater than 94 percent; Cari’s blood oxygen saturation level was 90 percent at the time of her exam and an initial arterial blood gas analysis done when she was admitted to the hospital revealed her arterial P02 was 54 mmHg. How do these clinical findings relate to the internal respiration in Cari’s body?
If Cari was at a normal resting oxygen level should be about 94% with no added oxygen. (Tortora G. W., 2013)
9. Which of the symptoms Cari has described is due to lack of oxygen and reduced oxygen exchange at her tissues?
When the oxygen carrying capacity of hemoglobin with a rising pC02 will lower since pCO2 that lower since CO2 will take over the o2’s.
10. As Cari’s Pc02 rose, how was the oxygen-carrying capacity of hemoglobin affected?
When the PH and Pc02 were lowered her rate of breathing would also lower so there is added oxygen in the hemoglobin. (Tortora G. W., 2013)
11. How would administration of oxygen enhance Cari’s central drive to
