Efficacy and Ventilatory Responses to VHI in Atelectasis Patients

"Hyperinflation using a ventilator or ventilator hyperinflation technique (VHI) was developed from the manual hyperinflation (MHI) technique. There is no need to disconnect the patient when using the VHI technique and consequently there is no loss of PEEP and little or no risk of the adverse effects associated with MHI."

Conventional treatments are the routine treatment that patients were received from the physical therapist who take care them. The routine treatments are consist of chest physical therapy techniques (i.e. vibration, positioning, etc.) and others treatment (i.e. passive movement).
