Based on the Siggard-Andersen Acid-Base Alignment Nomogram, this handy chart allows you to comfortably interpret a neonatal blood gas result in seconds. The chart is 8.5 x 11 inches and is laminated so that it can be easily cleaned if used at a patient’s bedside. Instructors may supply a dry-erase pen during blood gas instruction so that students may mark on the nomogram chart, erase and start over. Color-coding is used to help students decide whether a blood gas is normal, compensated or uncompensated acidosis or alkalosis. Step by step instructions and blood gas interpretation rules are included on the backside of the card. (Dry-erase pen not included).
