CPARLENE Mannequin - This Mannequin provides maximum student/instructor feedback in four practice modes: compression rate, compression depth, ventilation duration, and ventilation volume. Red light indicates improper hand placement. The performance of each skill is displayed separately while averages are stored in the memory. With the flip of a switch, memory unit evaluates performance based on child or adult CPR standards. The Mannequin with both memory and printer will print out test strips that plot and tabulate test performance skills indicating average rate, depth, and placement of compressions and average duration and volume of ventilations in either adult or child mode. Jaw thrust feature. Power saver feature automatically turns unit off, but retains previous data. Low battery indicator. Five-year warranty.
