About the test types

FVC Perform new Forced Vital Capacity test

“FVC” stands for forced vital capacity. The goal of an FVC effort is to measure the volume
forcefully.

Continue saved test

ECG

A test that provides data to compare with pre-test data. Sometimes called post-Rx or post­BD (bronchodilator). A post-test must follow a pre-test within 24 hours.

Change test type:

Auto ECG

• A report typically showing a 10-second acquisition of 12 leads of ECG information
combined with patient data, measurements, and optional interpretation. Auto ECGs
can be saved to the electrocardiograph’s test directory or to a USB mass-storage
device.

Rhythm ECG

• A continuous, real-time printout of rhythm strips with a user-defined lead
configuration. Rhythm ECGs are printouts only. They cannot be saved.

Stat ECG

• An auto ECG that starts without waiting for you to enter patient data.
