Test to determine lung volumes using gas dilution or washout

This test measures lung volumes by either diluting or washing out a known amount of gas in your lungs. You'll breathe in a harmless gas, then exhale. The exhaled air is analyzed to assess your lung capacity and function.

This service was performed 13 times for 13 patients

Test to determine lung volumes using sensors

This test, called spirometry, measures lung capacity using sensors. You breathe into a mouthpiece attached to a device that records the amount and rate of air you inhale and exhale. It helps diagnose and monitor lung conditions.

This service was performed 23 times for 23 patients

Test to examine how well the lungs exchange gases

This is a test called a pulmonary function test, which helps understand the efficiency of your lungs. It measures how much air your lungs can hold, how quickly you can move air in and out of your lungs, and how well your lungs put oxygen into and remove carbon dioxide from your blood.

This service was performed 40 times for 40 patients

Test to measure expiratory airflow and volume

NPI NPI Number Validation

How NPI Validation Works

The NPI validation process uses the ISO-standard Luhn algorithm, a mathematical "handshake", to ensure that a provider's 10-digit ID is authentic and free of common typing errors.

To verify the NPI 1144297748, we treat the final digit (8) as the Check Digit—the target answer we need to reach. The process begins by taking the first nine digits and adding a constant value of 24, which accounts for the "80840" prefix required for all U.S. health identifiers. We then double every other digit starting from the right and sum the individual digits of those results together. For this specific NPI, that total comes to 72. The final step is to find the difference between that total and the next multiple of ten (80 - 72 = 8).

Digit-by-digit view

Use the first nine digits for the calculation. Starting from the right, double every other digit. The last digit is the check digit and is not part of the calculation.

Step 1: Double every other digit from the right

Starting with the rightmost digit of the first nine digits, double every other value. If doubling creates a two-digit number, add those digits together.

1 → 2 4 → 8 2 → 4 7 → 14 → 5 4 → 8

Step 2: Add all digits plus the NPI constant

Add the transformed values, the unchanged digits, and the constant 24.

2 + 1 + 8 + 4 + 4 + 9 + 1 + 4 + 7 + 8 + 24 = 72

Step 3: Find the amount needed to reach the next multiple of 10

The next multiple of ten after 72 is 80. The difference is the calculated check digit.

80 - 72 = 8
This NPI is valid
The calculated check digit is 8, which matches the last digit of 1144297748.
