Changes

We had a patient who used one of these masks with a pacemaker and reported to us that, as every morning when he got up he felt really strange in the chest. we discovered that this was because, when he took off his mask, the <big>'''magnetic strap would pass near his pacemaker and reset it to 120 beats per minute'''.</big> Needless to say, we took that mask away from him and found an alternative. It can also interfere with hearing aids, cochlear implants and similar. If in doubt be cautious and do some research.
