High frequency chest wall compression
WebHigh-frequency chest wall oscillation (HFCWO) is commonly used by cystic fibrosis (CF) patients for airway clearance. The primary objective of this study was to determine whether the use of a newer HFCWO device that generates oscillations with a triangular waveform results in greater sputum production than a commonly used device that generates … Web1 de abr. de 2024 · High-frequency chest wall oscillation and compression devices represent an alternative method of airway clearance in non-compliant subjects, where mucus localization is peripheral. The pressure variations generated by the device act on the chest and consequently on the airflow, favoring the expiratory phase and the interaction …

WebTen anesthetized, paralyzed adult cats were ventilated by high frequency chest wall compression (HFCWC) at 3, 5, 7, and 9 Hz by means of a single chamber cuff enclosing the thorax from the axillae to the xyphisternum. The effects of HFCWC in terms of gas exchange, end-expiratory lung volume, and res … WebWe investigated the effects of high-frequency chest wall compression (HFCWC) on peripheral and tracheal mucus clearance in anesthetized spontaneously breathing dogs. HFCWC was achieved by oscillating the pressure in a thoracic cuff with a piston pump. Regional lung retention of a technetium-99m sulfur colloid aerosol was monitored with a …
WebA high frequency chest wall oscillation therapy system includes an air pulse generator. The air pulse generator includes control circuitry and a fluid chamber carrying a fluid. A motor is configured to generate compression and expansion of the fluid in the fluid chamber to generate pressurized fluid. A pressure sensor detects a pressure of the … WebAbstract. The authors developed a high-frequency chest compression (HFCC) device to aid in mucous clearance for patients with obstructive lung disease. The device, designed for self-therapy, consists of a large-volume variable-frequency air-pulse delivery system and a nonstretchable inflatable vest worn by the patient.
