A ventilator is configured to assist a user with breathing, while eliminating the need for extraneous sensors and tubing normally found in prior art ventilators. The ventilator relies on a predetermined relationship between a measurable quantity associated with a compressed gas and the maximum pressure of that compressed gas upon delivery to the user. The measurable quantity may be mass flow rate of the compressed gas or pressure within a delivery lumen used to transport the compressed gas, among others. Based on the predetermined relationship, the control logic within the ventilator determines whether the pressure of compressed gas delivered to the user exceeds a maximum allowable pressure. When the maximum pressure is exceeded, the control logic initiates corrective action to reduce the pressure of the compressed gas.

A portable gas fractionalization system with built-in administrative and self-diagnostic functions is provided. The system includes a multiple mode programmable controller which has a operations mode and a diagnostic mode that can be activated by a triggering event. The triggering event can be when a user enters a command input, when one or more process parameters deviate from a nominal value, or when the system is scheduled to perform self-diagnostics. The system also includes a multi-level user interface which is integrally formed with the system. The user interface includes a multi-level display screen and a plurality of user command functions. The diagnostic information displayed on the display screen can be in an abbreviated code form so that only technicians would be able to interpret meaning of the code.

The additional compressors can also be removed when not in use so as to reduce weight of the system. In some implementations, the system housing reserves a certain amount of space for accommodating additional compressors and related components, which can be added to the system as after market parts. In other implementations, the additional compressor can be located external to the system.
