Both the OxyArm™ and Capnoxygen mask provide clinically useful capnographic monitoring capability in volunteers

PurposeTo compare the capnography monitoring performance of the new OxyArm™ (OA) with the Capnoxygen mask (CM), a conventional oxygen mask with a carbon dioxide sampling port.MethodsEleven healthy volunteer adult subjects underwent capnographic monitoring (in a non-randomized, un-blinded crossover study) at baseline and while receiving oxygen at seven different flow rates (0.5, 1.0, 2.0, 4.0, 6.0, 8.0, and 10 L· min−1), applied first with the …
