It generally takes about ten minutes and pressurize and de-pressurize the chamber, so please plan on an hour and fifteen-minute window for your appointment. Please be on time, otherwise, your pressured time in the chamber will need to be reduced. Please be aware of our 24-hour cancellation policy. If an appointment is canceled within 24 hours, or the patient is a no-show, they are responsible for the cost of the appointment. Additionally, same day appointment requests cannot be guaranteed, please attempt to schedule at least one day in advance.
