The OxyHeal® 4000-Omega is oriented as a horizontal semi-cylindrical (flat bottom) hyperbaric oxygen therapy (HBOT) chamber system. It is typically a two or three compartment system designed to treat 6-18+ patients simultaneously depending on the model type selected. This unique multiplace design (?) allows more usable space inside the chamber for patients, staff, and medical monitoring equipment as required. Patients are treated in the main compartment(s) and this sophisticated HBOT system is designed to increase a patient's level of care because healthcare staff will be inside the chamber attending to patients at all times during treatments. Additionally, healthcare staff have the ability to enter or exit the chamber if necessary during a treatment via the transfer compartment without interrupting the current HBOT treatment session. The OxyHeal® 4000-Omega can be customized enabling chamber doors, viewports, diameter, length, seating, patient capacity, ATA, etc. to meet precise customer specifications. The OxyHeal® 4000-Omega is designed, fabricated, assembled, inspected, tested, and certified in accordance with the Safety Standards for Pressure Vessels for Human Occupancy (PVHO).
