29 The technique is based on the use of a loudspeaker to send small-amplitude oscillatory pressure waves at the entrance of the airway and, from the recording of the pressure and flow variations that these impulses impose to the respiratory system, to be able to calculate the impedance (Zrs)...
Peak expiratory flow rate is the measurement of how much the patient can blow out of their lungs in one breath. It is a crude measurement and not as accurate as Spirometry. However it is useful for patients to perform themselves, especially when they are
Home-monitoring of peak expiratory flow rate using the mini-Wright peak flow meter is a useful technique for determining whether or not unexplained respiratory symptoms are caused by asthma. It is of particular value when airflow obstruction cannot be demonstrated at the time of consultation.关键词...
