Zoll was recently been cleared by the FDA for a new E Series defibrillator with CO2 Monitor. The new product is designed to detect carbon monoxide (CO2) poisoning with the push of a button, enabling early treatment. The E Series features a see-through CPR filter, Real CPR Help for real-time feedback of chest compressions, and wireless 12-lead transmission.

Last August, Zoll received approval from the FDA to sell a new LifeVest defibrillator.
