Comparison of O2 and EtCO2 achieved by the polypropylene and conventional polyvinyl chloride face mask in healthy individuals

Published:February 29, 2016DOI:
      The polyvinyl chloride (PVC) type face mask has been a standard model for administering oxygen postoperatively. Recently, a polypropylene-based face mask, EcoLite (“EcoLite”; Sentri Intersurgical Ecolite adult mask with CO2 monitoring and tube, Intersurgical, Berkshire, UK), which has a new shape, was developed. We conducted a prospective crossover study in healthy individuals to evaluate the efficacy of oxygenation with the EcoLite and conventional PVC medium concentration face mask with a luer lock connector enabling the connection of a monitoring line, the other end of which is connected to a capnometer.
