ATA (Atmospheres Absolute): A measurement of the total pressure inside the chamber. 2ATA represents a pressure level double that of standard atmospheric pressure at sea level.

Air Booster Module (Air Compressor): The mechanical engine responsible for pumping air into the chamber to achieve and maintain the required internal pressure levels.

Air Conditioning Module: A climate control system consisting of internal and external units designed to cool and dehumidify the chamber, preventing it from becoming too warm during pressurization.

Air Volume & Wind Speed: Technical metrics indicating how much air is circulated through the climate control system per hour and the velocity at which it moves to maintain a consistent internal temperature.

Aluminum Alloy: A high-strength, lightweight metal frequently used for the chamber shell to ensure it can withstand constant pressurization cycles safely.

BIBS (Built-In Breathing System): A specialized internal mask or hood system that delivers pure oxygen directly to the user, allowing the rest of the chamber to be pressurized with regular air.

Chamber Dimensions: The external measurements (Length, Width, Height) of the unit, used to determine the necessary floor space and ceiling height for installation.

Control Panel (HMI): The Human-Machine Interface, typically a touchscreen, used by the operator or user to select therapy modes, monitor real-time data, and manage the session.

Door Thickness: The specific measurement of the entry hatch. Thick, aviation-grade materials are used to ensure the door remains structurally sound and airtight under high pressure.

Emergency Stop & Pressure Relief: Critical safety mechanisms, including manual buttons and automatic valves, that allow for the immediate and controlled depressurization of the chamber in an emergency.

HBOT (Hyperbaric Oxygen Therapy): A medical or wellness treatment where a user breathes pure oxygen in a pressurized environment to increase oxygen levels in the blood and tissues.

Intercom: A dedicated audio communication system that allows the person inside the chamber to speak clearly with someone on the outside at any time.

Multiplace Chamber: A hyperbaric system designed with a larger interior to accommodate more than one person during a single therapy session.

Noise Level (dB): The volume of sound produced by the machinery during operation. Lower decibel ratings ensure a more peaceful and relaxing environment for the user.

Output/Outlet Pressure: The force at which oxygen or air is discharged from the support modules. This pressure must exceed the internal chamber pressure to ensure a steady supply.

Oxygen Flow (L/min): The volume of oxygen delivered through the breathing system, measured in Liters per minute.

Oxygen Module/Concentrator: The hardware unit that filters ambient air to remove nitrogen, delivering a concentrated stream of oxygen to the user.

Oxygen Purity: The percentage concentration of oxygen delivered to the user, with professional systems typically providing a purity of 93% ± 3%.

Pressure (ATA): Measured in Atmospheres Absolute, this is the sum of the standard atmospheric pressure (1ATA) plus any additional pressure generated by the chamber's compressor.

Voltage & Power (W): The electrical specifications (e.g., 240V/110V) and energy consumption (Watts) required to run the chamber's various modules and electronics.

Weight: The total mass of the chamber and its components, essential for calculating floor load capacity and planning delivery logistics.
