## Dynamic Compression Ratio Formula

The following formula is used to calculate the Dynamic Compression Ratio.

**DCR = IVC / TDC**

- Where DCR is the Dynamic Compression Ratio (IVC:TDC)
- IVC is the volume at IVC
- TDC is the volume at TDC

## How to Calculate Dynamic Compression Ratio?

The following example problems outline how to calculate Dynamic Compression Ratio.

Example Problem #1:

- First, determine the volume at IVC.
- The volume at IVC is given as: 30.

- Next, determine the volume at TDC.
- The volume at TDC is provided as: 40.

- Finally, calculate the Dynamic Compression Ratio using the equation above:

DCR = IVC / TDC

The values given above are inserted into the equation below and the solution is calculated:

DCR = 30 / 40 = .75 (IVC:TDC)

Example Problem #2:** **

For this problem, the variables required are provided below:

volume at IVC = 60

volume at TDC = 20

Test your knowledge using the equation and check your answer with the calculator above.

DCR = IVC / TDC** = ?**
