Description
Mechanical percussion devices and high-frequency external chest compression devices provide external chest wall compressions through the use of a device such as a vest (e.g. ThAIRapy™ Vest, The Vest™, Hayek Oscillator, InCourage system, SmartVest). The generator produces an alternating flow of air into and out of the vest that rapidly compresses and releases the chest wall within a range of selectable frequencies and pressures. These devices or techniques can be applied by the patient.
