Final Jeopardy
Frequent, soft, gasp-like inhalations while speaking, like Dr. White in his IL videos, can indicate restrictive lung disease when spirometry confirms low FVC and a normal or increased FEV1/FVC ratio. If this progresses to chronic hypoxemia, certain cells in the posterior abdomen will directly respond to this hypoxemia by increasing release of what hormone?
Answer: Erythropoietin
In response to chronic hypoxemia, the kidneys sense decreased oxygen delivery and upregulate the synthesis of erythropoietin to stimulate red blood cell production.
