A comparison of the visual field restrictions with the M17 series protective mask and the MCU-2/P chemical-biological mask.
The U.S. Air Force and U.S. Navy recently adopted the MCU-2/P Chemical-Biological Mask to replace the M17 series of protective masks. Visual field plots were generated on a patient wearing each of these respirators. Although both resulted in a decrease of the visual fields, the magnitude of restrictions was far less with the MCU-2/P Chemical-Biological Mask.
