Your medical history and safety check will be performed by one of our HBOT certified clinicians. They will go over a list of Do's and Don'ts like not wearing lotions, hair sprays, lip balm, metal jewelry, etc, not taking in flammable devices like lighters or hand warmers, not smoking before entering or wearing perfumes (the odors linger in the chamber), and what devices you are allowed to bring in like books or phones or headphones. And we will pat you down every time you enter because people say "yeah, yeah, yeah." but then do it anyway and it puts us all at risk. We do it because we take your safety seriously.
