Bi-Level - Bi-Level system makes breathing easier and more natural for adult patients with Obstructive Sleep Apnea (OSA) who are having difficulty complying with continuous positive airway pressure therapy.

Continuous Positive Airway Pressure (CPAP) : One of the most common sleep disorders is sleep apnea - a disorder that causes a person's airway to close several times during one night's sleep. For those with sleep apnea, relief usually comes with continuous positive airway pressure (CPAP). Continuous Positive Airway Pressure (CPAP) devices deliver a prescribed level of positive pressure non-invasively to the upper airway for the treatment of sleep apnea. Extremely easy to use, CPAPs come with different features such as ramping to allow comfortable adjustment to the pressure; software to capture specific usage and breathing events; and automated altitude adjustment. Accessories, such as nasal interface applications and humidification devices are provided to afford maximum comfort to ensure patient compliance.

Defibrillator:   A device used to correct a dangerously abnormal heart rhythm, usually ventricular fibrillation, or to restart the heart by depolarizing its electrical conduction system and delivering brief measured electrical shocks to the chest wall or the heart muscle itself.

Diabetes (Type 2):  Type 2 diabetes is the most common form of diabetes. Having type 2 diabetes means that your body doesn't make enough insulin, or doesn't properly use the insulin your body makes. Insulin, which is made in your pancreas, helps your body's cells use sugar from your bloodstream, which comes from foods and drinks. Sugar is a source of energy for cells.

Helios Portable Oxygen Systems and Reservoirs:  small, lightweight, and long-lasting, encourages an active lifestyle for long-term oxygen therapy patients. No tubes, heavy canisters or batteries are required. The system is also extremely economical. Its pneumatic oxygen conserving device gives it a conservation ratio over continuous flow oxygen of approximately 4:1. This provides up to 10 hours of use at a setting of 2. The portable unit can be refilled in about 40 seconds from the home reservoir, which typically lasts four to six weeks between refills.

Infusion Pump:  Infusion pumps and controllers are used extensively for delivering intravenous fluids and drugs as part of the care of patients in hospital. These are usually pumpss but the term is often used loosely to describe an infusion controller which relies on the head of the fluid reservoir for its motive force, and merely controls the rate at which the fluid is dispensed.

Liquid oxygen systems - consist of a large main tank and one or two portable units. The portable units are used as needed for travel outside of the home. When they are empty, they can be refilled from the large tank. Portable units can be carried with a shoulder strap or cart. Liquid oxygen will evaporate if not used frequently. Therefore the portable units should be filled just prior to use.

Nebulizer:  is a type of inhaler that provides a fine mist of medication to the lungs. This is performed by breathing the medicated mist through a mouthpiece or mask attached to the nebulizer device, which is driven via a plastic tubing, attached to the compressor unit. The medications used in nebulizers help you by loosening the mucus in the lungs so it can be coughed out more easily, and by relaxing the airways so that more air can move in and out of the lungs. Nebulizer treatments take approximately 15 minutes to deliver the medication and are prescribed by your physician.

Oximeter:  This is usually a device which can distinguish between oxyhaemoglobin and reduced haemoglobin by measuring and comparing the absorption of red and infrared light. Bench models exist which take blood in a cuvette, but the technique can also be applied in vivo. In vivo models usually clip on to the ear and shine light through the ear-lobe (the heat from the lamp also acts to increase the blood circulation in the ear). On the other side of the ear-lobe are filters and photocells.

Oxygen:  Oxygen is a colorless, tasteless, odorless gas that is necessary for life. When we take a breath, we draw air containing 21% oxygen into our lungs. The oxygen passes from our lungs into our bloodstream, where it is carried in the red blood cells to all the organs and tissues of our bodies. Oxygen is needed by our organs and tissues to convert the food we eat into heat and energy, to maintain life.

Oxygen Concentrator:  An alternative to using piped or bottled oxygen to enrich the air supply to patients with lung disorders is to use an oxygen concentrator. This employs a 'molecular sieve' which is a mechanical filter which allows smaller molecules through more easily. Air is drawn through the sieve and the initial gas mixture delivered has an enhanced oxygen level. This mixture is retained, the system purged, and the process repeated. The retained gases are fed through the sieve repeatedly to progressively enhance the oxygen concentration. Usually two sieves are in use which work alternately. Portable units are available which are suitable for use by the patient at home, thus removing the need for bottled gas deliveries.

Pacemaker:  Pacemakers may be external devices connected to the heart via long catheters passed through a vein or even by selectrodes placed in the oesophagus, but more commonly they are implanted devices operating from internal batteries or via an inductive link to an external power source. There are two basic types of device, the fixed rate pacemakers, and those which provide pacing pulses only when required. These latter types are called non- competitive or demand pacemakers because they pulse only when intrinsic activity fails.

Respirator:  This is a device for artificial ventilation of the lungs, also known as a resuscitator. The term is normally applied to an emergency apparatus consisting of a self-inflating bag, valves, and face mask, perhaps with provision for an oxygen supply. Common types are the Ambu, Air Viva, Cardiff inflating bellows, Oxford inflating bellows and the Samson infant resuscitator.

Ventilation, positive pressure: The provision of oxygen under pressure by a mechanical respirator, a machine designed to improve the exchange of air between the lungs and the atmosphere. The device is basically designed for administering artificial respiration, especially for a prolonged period, in the event of inadequate spontaneous ventilation or respiratory paralysis.

The mechanical ventilator was invented in 1927 by Philip Drinker and Louis Agassiz Shaw. It consisted of an iron box (and so was called an iron lung) plus a bed and two vacuum cleaners. The next model was made by Warren Colins and was inaugurated on October 12, 1928 at the Children's Hospital in Boston to help a girl with polio breath.

Ventilator: A ventilator is a machine which mechanically assists patients in the exchange of oxygen and carbon dioxide (sometimes referred to as artificial respiration).
