The 840 Ventilator System with ET/Tracheostomy Tube Compensation, TC, Option is used to provide continuous ventilation to patients requiring respiratory support. This device is used for a wide range of patients from infant to adult and for a wide variety of clinical conditions.

The 840 Ventilator System is a "Continuous Ventilator", a Class II device, per 21 CFR Part 868.5895. This device is designated as Class I, Type B equipment, per IEC 601-1. The 840 Ventilator's gas delivery system consists of two proportional solenoid valves, PSOLs and an active expiratory valve. Previously cleared modes of ventilation include Assist Control, AC, Synchronized Intermittent Mandatory Ventilation, SIMV and Spontaneous, SPONT. The 840 Ventilator System supplies mandatory or spontaneous breaths with a preset level of positive end expiratory pressure, PEEP, trigger sensitivity and oxygen concentration. A mandatory breath can be either pressure or volume controlled, except in the optional BiLevel mode, when it is always pressure-controlled. A spontaneous breath type allows patient inspiratory flows of up to 200 L/min, with or without pressure support. This 840 Ventilator modification comprises the addition of a new ET/Tracheostomy Tube Compensation, "TC", feature. This feature is implemented on the 840 Ventilator through additional functionality in software and by using the existing User Interface panel. "TC" has been added as a Breath Type choice in the Touch Screen SPONT Type menu. The ventilator's pneumatic design and electrical circuitry remain functionally unchanged.

The Puritan-Bennett Helios Portable Liquid Oxygen System is intended to provide supplemental oxygen to oxygen therapy patients who may have difficulty extracting oxygen from the air that they breathe. It is intended to be used as an ambulatory source of oxygen both inside and outside the patient's home. It is not intended as life sustaining or life supporting device. The device has no contraindications.

The Helios portable liquid oxygen system consists of a vacuum insulated cryogenic container and plumbing that includes pressure relief valves, heat exchanger tubes and a pneumatic conserving device. The vacuum insulated container allows oxygen to be stored in its liquid state under pressure where the system pressure is controlled by the relief valve. When the patient opens the flow control valve, the liquid oxygen is withdrawn from the container into a vaporizing coil. Once in the vaporizing coil, ambient heat is absorbed by the liquid oxygen, converting it into a gas and warming it to near room temperature. The gas finally passes through the flow control valve and on to the patient at the prescribed metered rate. The device is intended to be used in conjunction with a larger liquid oxygen reservoir where it is filled by mating it to the fill connection on the top of the larger system. The Helios device is a purely mechanical device and contains no electrical or electronic components.

The Puritan-Bennett Aeris 590 oxygen concentrator with OCI is intended to provide supplemental oxygen to patients who may have difficulty extracting oxygen from the air that they breathe. It is intended to be used with both pediatric and adult patients. It is not intended as life sustaining or life supporting device. The device has no contraindications.

An oxygen concentrator takes in room air, filters it and separates the nitrogen from the air under pressure, allowing only oxygen and trace gases to pass through to the oxygen outlet connection to the patient while exhausting a nitrogen-rich air mixture back into the room. The principle components of the Aeris 590 oxygen concentrator include a compressor, two molecular sieve containers, a valve system and a printed circuit board. The compressor draws in room air, pressurizes it and forces it through the pneumatic circuit of the device. As the air passes through one sieve container, the nitrogen bonds with the molecular sieve material within the pressurized container and allows only the oxygen and trace gases to flow out of the container. This oxygen rich mixture (+90% oxygen) is then delivered to the patient at a regulated pressure and flowrate. The valve system regulates the airflow through the sieve containers alternately. While one is pressurized and producing oxygen, the other is being depressurized and exhausting the nitrogen in preparation for the next cycle. A programmable logic device on the printed circuit board controls the timing of this cycling process. The OCI (Oxygen Concentration Indicator) provides an indication of the oxygen concentration of the output gas and includes alarm features.
