Ventilation aid
Airway devices are easy to use tool for artificial respiration , which make direct contact with the mouth unnecessarily to breath receiver and thereby reduce any possible inhibitions on the part of the respiratory donor and the risk of infection. They are intended for non-medical use; professional helpers in the hospital and emergency services use resuscitators .
A distinction is made between masks and foils.
Ventilation mask
The ventilation mask has a circumferential, air-filled bead for sealing. Unlike when using a resuscitator, the respirator has both hands available, so that even inexperienced users can place the mask tightly on the recipient's face. The mask allows ventilation overhead or from the side (then one hand grips the top of the mask and presses it onto the nose, while the other hand grips the chin and holds the mask in place with the thumb). Working with both hands also allows you to fix the mask and stretch your head at the same time. The increased distance between the respiratory donor and recipient results in a further advantage that the donor can more easily observe the rise and fall of the recipient's chest.
Ventilation foil
The ventilation foil is smaller, lighter and more cost-effective than the mask and is therefore well suited for constant carrying in the first- aid kit , in the wallet or as a key ring. In order to ensure a certain protection against infection during use, a valve or a filter is incorporated into the film. The resuscitator places the foil on the patient's face and then ventilates either mouth-to-mouth or mouth-to-nose (as learned in the first aid course ). To prevent dropping or chutes of the film (eg. As at alternating with the artificial respiration performed cardiac massage ) are rubber strips on the left and (drawn to the right at the edge of the film over the patient's ears in the picture on the right is only the left elastic see ). In practice, however, it has been shown that such films wet through during ventilation and therefore cannot offer any protection against HIV infections.
