Hey guys, Will you please help me on my math. I am having a hard time with this, and if someone can show me the steps to get the answers and where I pug in the answers in the problem that would help me with the rest of the questions. Thank you.

% of Dead Space Equation (symbolized by VDVTVDVT):

VDVTVDVT = PACO2PETCO2PACO2PACO2-PETCO2PACO2

  • PACO2 is the partial pressure of carbon dioxide in the arterial blood.
  • PETCO2 is the partial pressure of carbon dioxide the patient exhales.
  • Answers will be in decimal form, which can be converted to % dead-space.
  • Pressures are expressed in millimeters of mercury or mmHg.

This equation is used to determine the percentage of ventilation the patient inhales that does not participate in gas exchange. Gas exchange is the transfer of oxygen from the lungs to the blood and the transfer of carbon dioxide from the blood to the lungs. After the percentage of dead-space is calculated, it can then be multiplied by the patient's tidal volume VT to determine the exact volume VD (expressed in mL) that is considered dead-space or wasted ventilation. Some dead-space ventilation is normal. Abnormal values are values that are greater than .33 or 33%.

Using the equation above, first calculate the % Dead Space using the given information below. Express that answer as a percent. Then, calculate the Dead Space Volume or wasted ventilation. Lastly, calculate the Volume Not Wasted (Volume Not Wasted = Tidal Volume - Dead Space Volume). Round your answers to the nearest hundredth, if necessary, and be sure to pick the correct labels for your answer.

PACO2 = 42 mmHg

PETCO2 = 37 mmHg

Tidal Volume = 350 mL
