Product Description

1.What is an artificial nose?An artificial nose is a medical device used in the care of patients with a tracheostomy. It fulfils and replaces those important tasks of a natural nose, when breathing is no longer possible via nose, mouth and throat. It has the following function:Warming of the airParticle filtering of the airHumidification of the airRestoration of breathing resistanceAvoid cross infection2.Terms and classificationArtificial noses are so-called humidity and moisture exchangers. The following terms refer to the same thing:HME (Heat and Moisture Exchanger)Artificial noseArtificial noses belong to the class of medical devices of breathing air conditioners. Here, a distinction is made between active and passive methods. Active respiratory humidifiers actively bring heat and moisture into the air.  Artificial noses belong to the class of "passive respiratory humidifiers. These store heat and moisture from the exhaled air in order to emit these back into the inhaled air. These functions are carried out by the filter medium.3.Where and how are artificial noses attached?In tracheotomised, spontaneously ventilated patients, the artificial nose is attached to the connector at the tracheal cannula. In spontaneously ventilated patient, they represent the only effective means of taking over the functions of humidifying, heating and filtering the air, and to restore the breathing resistance.

During artificial respiration, an HME as a passive humidifier is an effective and inexpensive alternative to active humidifying systems. 4.Why are artificial noses so important?Without the use of an HME, air would be too cold and too dry to breathe, and breathing resistance would be too low. Even after only a few minutes of not using an artificial nose (e.g. immediately after surgery), the tracheal mucus membrane dries out and ossification occurs, drastically increasing the risk of infection. In addition, the HME is an efficient filter of foreign matter, such as dirt, dust particles and insects. An HME also partially recreates the lost resistance when exhaling. It keeps the alveoli open in order to improve the supply of oxygen to the blood. Thus, an HME helps to keep the pressure levels in the lungs similar to those before surgery.5.How does an HME work?Artificial noses are generally made of a plastic shell and a material that can assume the function of a natural nose, the so-called filter medium. This could be either paper or foam. The filter medium (also known as moisturizing medium) is covered in a layer of hygroscopic salt, which binds the moisture in the exhaled air and releases it again when inhaling.
