The vibrations move mucus from the surface of the airways. Also create vibrations when a patient breathes out.They use resistance to make it more difficult during the breath out, like non-oscillating PEP devices.Commonly known by their brand names (Flutter®, Acapella®, AerobikA®, and RC-Cornet®), these types of oscillating PEP devices work in two ways. The person blows all the way out many times through a device. An oscillating (or vibratory) positive expiratory pressure (OscPEP) device is a form of PEP that combines high-frequency air flow oscillations with positive expiratory. Examples of this type of device include the TheraPEP®, Resistex PEP Mask, and the Pari RC Cornet Mucus Clearing DeviceTM.Ģ.A PEP device increases resistance to expiratory airflow to promote mucus clearance by preventing airway closure and increasing collateral ventilation.Two types of airway clearance devices are the positive expiratory pressure device (PEP) and the oscillating positive pressure device. Effective airway clearance promotes movement of mucus proximally.Retains airways from collapsing and prolongs expiratory flow.Promotes collateral ventilation, allowing pressure to build up distal to the obstruction (collateral ventilation is a phenomenon found in the human lungs where alveolar structures are ventilated through channels that bypass normal airways).The increase in pressure is transmitted to airways creating back pressure stenting them during exhalation, preventing premature airway closure and reducing gas trapping. This page takes a look at some of the latest PEP devices available on the market. eg.according to CDC (the Centres for Disease Control and Prevention), in 2018, around 9 million adults were diagnosed with chronic bronchitis which eventually leads to higher requirements for PEP devices, fueling the market.Increasing prevalence of chronic obstructive pulmonary disease (COPD) along with asthma is one of the major driving factors for the industry.Increased geriatric population coupled with higher incidences of chronic conditions drive the PEP devices market growth. The therapy, which is administered by breathing through a special device helps: One of the most frequently prescribed airway clearance therapy (ACT) options for patients with chronic lung conditions or decreased lung volumes are positive expiratory pressure therapy (PEP) devices.ĭuring PEP therapy, the patient exhales against a fixed-orifice resistor, generating pressures during expiration that usually range from 10 to 20 cm H2O.(14-24) PEP does not require a pressurized external gas source.
