Data and Curve Storage and Recall

Last Updated: March 16, 2017

Definition - What does Data and Curve Storage and Recall mean?

In spirometry, data and curve storage and recall relates to a computer software system containing patient information that covers personal identification details including test session results which indicate separate breathing maneuvers displayed on a graphical chart as a curve that assesses the lung capacity volume. This corresponds to a standard numerical range value measuring forced expiration (breathing out) during an examination. During a test, a patient blows into a spirometer as hard and fast as possible and then the output is translated into the database interface showing a curve on a chart, combined with previous numbers from previous sessions, and is used for comparison in determining whether the representative curve is accepted or rejected.

WorkplaceTesting explains Data and Curve Storage and Recall

In spirometry, data and curve storage and recall pertains to a computerized database comprised of patient information concerning personal identification recognition in addition to test session results. It illustrates expiration (breathing out) patterns measured by a chart displaying a curve that represents the airflow volume released from the lungs to determine normal or erratic breathing habits. During testing, patients are provided with a spirometer in which they are instructed to blow a forceful rush of breath, depleting all the air from their lungs. The results are then transmitted to a software interface that specifies the maneuver(s) conducted in terms of measuring variables such as, forced expiratory volume (FEV), forced vital capacity (FVC), and peak expiratory flow (PEF).

These factors are presented visually in a graphical chart format comparing differences between the most recent testing curve in proportion to previous test indicators that fall within a standard range of regular airflow produced by the lungs. A technician observes the curve results for comparative analysis from repeated sessions before determining if a curve is accepted or rejected based on a standard numerical value that means a successful clearance according to the software database system.
