What is the A-a gradient, and why is it significant?The A-a gradient is the alveolar-arterial oxygen gradient and represents the driving force of oxygen from the alveolar sac into the artery. JavaScript is disabled. /Rotate 0 /Creator Oxygen consumption varied directly with Vt and inversely with compliance, increasing from 4.8 +/- 0.07 L/min with the HC-500 mL Vt model to 6.2 +/- 0.05 L/min The oxygen consumption is the amount of oxygen that is used up by the organism's body over time. endobj Patients who are on long-term ventilation may require a feeding tube directly inserted into the nose or mouth, or through a hole made in the stomach. A cardiac index below what value can be life-threatening?< 2.2, 36. FiO. Use this heart rate recovery calculator to determine the change in your heart rate after the first minute of rest after exercise. To determine your VO2 max if your resting heart rate is 60 bpm and you're 30 years old: Calculate your maximum heart rate by multiplying your age by 0.7 and deducting it from 208, which equals 187 bpm.

A respirometer measures how much oxygen is used during cellular respiration. Enter Total Supply Step 3. Numerous studies reveal that high-intensity interval training (HIIT) workouts are associated with increased VO2 max. "VE" stands for the volume of air expired in mL/min, "VI" represents the volume of air inspired in mL/min, "FeCO2" stands for the fraction of CO2 in expired air and "FiCO2" stands for the fraction of CO2 in inspired air.
