|Description of data elements available in PFT data mart|
|Parsed Numeric Columns||Spirometry (measures the airflow in and out of the lungs)||54|
|Lung volumes (assess the volume of air associated with different phases of the breath)||26|
|Diffusing Capacity for Carbon Monoxide (measures the ease with which a test gas (carbon monoxide) crosses the air sac membrane into the blood stream)||12|
|Pulse Oximetry (assesses the oxygenation of hemoglobin)||2|
|Anthropometric (height and weight)||2|
|Parsed Non-numeric Columns||Non-numeric data about patient (race, ethnicity, ordering physician, notes)||6|
|Data about measurements (date, technician, etc.)||5|
|Totals||Total number of potential measures parsed into discrete data elements||107|
Not all patients undergo all the components of each PFT so the PFT report within the electronic health record may contain fewer measures (Additional file 1: Figure S1).
