It is designed to be operated in conjunction with a laptop computer, and derives its operating power entirely through a USB port. #Spirometry#Lung function test #Respiratory health #Pulmonary function test #Spirometer device #Forced vital capacity (FVC) #Forced expiratory volume in one second (FEV1) #Peak expiratory flow rate (PEFR) #Respiratory conditions #Asthma #Chronic obstructive pulmonary disease (COPD) #Pulmonary disorders #Lung volume #Lung capacity #Spirometry interpretation #Spirometry guidelines #Spirometry training #Spirometry technique #Spirometry results #Spirometry accuracy #selangor #johor #rental #aros #seremban #wheelchair #breathing
