Chapter 7, Problem 1CAQ1

Summary Introduction

To review:

The given blank space in the statement, “In the emergency department, even though the patient’s ${\text{Pa}}_{{\text{CO}}_2}$ was very high ($\text{539 mm Hg}$), the ${\text{CO}}_{\text{Hb}}$ level of 47 percent (enhanced……; impaired…….) the hemoglobin’s ability to carry oxygen”.

Introduction:

The measurement of the partial pressure of carbon dioxide (${\text{Pa}}_{{\text{CO}}_2}$) and carboxyhemoglobin (${\text{CO}}_{\text{Hb}}$) in blood is important to test the function of the lungs and the risk of any future lung diseases. The level of high carbon dioxide and carbon monoxide will cause a decrease inflow of oxygen into the blood through the alveoli, which leads to less binding of oxygen with the hemoglobin molecule. This condition could cause conditions like anemia.
