Investigation of non-uniform airflow signal oscillation during high frequency chest compression
BACKGROUND High frequency chest compression (HFCC) is a useful and popular therapy for clearing bronchial airways of excessive or thicker mucus. Our observation of respiratory airflow of a subject during use of HFCC showed the airflow oscillation by HFCC was strongly influenced by the nonlinearity of the respiratory system. We used a computational model-based approach to analyse the respiratory...
متن کاملHigh frequency chest wall oscillation in cystic fibrosis.
Airway clearance is considered an integral component of the management of cystic fibrosis (CF).RecentCFpulmonaryguidelines made recommendations using the US Prentative Service task Force (USPSTF) grading scheme (a system which provides a mechanism toweigh the quality of evidence and the potential harms and benefits) on airway clearance. 2 These guidelines recommended thatairwayclearanceshouldbe...
متن کاملVolume delivery during high frequency oscillation.
AIM To examine the delivered volume during "high volume strategy" high frequency oscillation, used as rescue treatment in preterm infants; and to identify factors, other than frequency and oscillatory amplitude, influencing the magnitude of volume delivery. METHOD Twenty infants (median gestational age 29 weeks) were studied on 45 occasions. Two oscillator types were used (SensorMedics and SL...
متن کاملHigh-frequency chest wall compression therapy in neurologically impaired children.
BACKGROUND Children with neurological impairment often suffer from insufficient airway secretion clearance, which substantially increases their respiratory morbidity. The goal of the study was to assess the clinical feasibility of high-frequency chest wall compression (HFCWC) therapy in neurologically impaired children with respiratory symptoms. METHODS This was a single-center, investigator ...
متن کاملEffects of positive end-expiratory pressure on oscillated flow rate during high-frequency chest compression.
OBJECTIVE To investigate the effects of positive end-expiratory pressure (PEEP) on end-expiratory lung volume (EELV) and mean oscillated flow rate (VOSC) during high-frequency chest compression (HFCC) in normal subjects and patients with severe COPD. DESIGN Comparative study. SETTING Pulmonary function and lung mechanics laboratory, University of Alberta Hospitals. PARTICIPANTS Six normal...
