PEEP valves and adapters to them

PEEP (Positive End Expiratory Pressure – peep – Positive Pressure at the End of Exhalation). PEEP – valve design was invented to fight expiratory closure of the Airways, which in English sounds like air trapping (literally – air trap). In patients with chronic obstructive pulmonary disease bronchial lumen decreases due to the swelling of the mucous membrane. When you exhale the muscular force of the respiratory muscles through the fabric of light is transmitted to the outer wall of the bronchus, further reducing his height. Part of the bronchioles, not having a skeleton of cartilaginous half-rings, clamps down completely. The air is not exhaled, and locked in his lungs, like a trap (there is air trapping). Consequences – violations of gas exchange and hyperinflation (hyperinflation) of the alveoli. Peep (PEEP) is measured in inches of water column (cm H2O) and millibar (mbar or mbar). 1 millibar = 0,9806379 cm of water column. Currently, there are a large number of devices for respiratory therapy and create the effect of PEEP that are not medical ventilators, including the PEEP valve manual ventilation devices.
