BACKGROUND
FREE-ASPIRE is a electromedical machine for removing broncho-alveolar mucus. It is a new technology called VAKUM that can improve the removal of secretions in a non invasive way by accelerating the expiratory flow .
The secretions are mobilized into the upper airways in patients inable to expectorateor swallow them .
Its effectiveness in improving the ventilation , also in peripheral pulmonary zones , and redistribuiting the blood perfusion has been documented by pulmonary scintigraphy from ventilation and perfusion .
METODOLOGIA
6 patients (5 m, 1 f), average 70,67 ± 8,41 with sencondary light-moderate pulmonary hypertension due to COPD or heart failure in stable phase (EF > 40%) underwent ECHOCARDIOGRAPHY
before and after FREE-ASPIRE treatment (20 minutes), during a medium follow-up period of 72 hours, to evaluate PAPS and IT.
THE AIM OF THIS STUDY WAS TO EVALUATE THE IMPACT
OF THIS TRAITMENT ON THE REDUCTION OF PULMONARY
PRESSION TROUGHT THE REDUCTION OF PERIPHERAL PULMONARY RESISTANCES
CONCLUSIONI
Free-aspire is an effective and safe treatment to reduce PAPS and to increase right ventricle inflow.
This results was maintained for 72 hours.
Furter studies with greater numbers of pts are required in order to confirm tath this apparatus, by means of expiratory flow acceleration, increase the cardiac output, reduces pulmonary resistance and vascular pulmonary resistances determinimg a redistribution of the blood perfusion and therefore reducing pulmonary hypertension
PAPS = Pulmonary sistolic pressure
TI = tricuspidal inflow
CO = cardiac output
