Positive effort dependence of maximal expiratory flow
, 1987 The maximal expiratory-flow volume (MEFV) curve in normal subjects is thought to be relatively effort independent over most of the vital capacity (VC). We studied seven normal males and found positive effort dependence of maximal expiratory flow between

, 1983 The first major advance in understanding expiratory flow limitation of the lungs came with the description of isovolume pressure-flow curves. These curves documented the existence of a volume-dependent limit to maximal expiratory flow and led directly ...

Airway dynamics in transition between peak and maximal expiratory flow
, 1985 Expiratory flow-volume curves with periodic interruption of flow showed flow transients exceeding maximal flow (Vmax) measured on the maximum expiratory flow-volume (MEFV) curve in a mechanical lung model and in five tracheotomized, vagotomized, open ...

Discriminant analysis of asthmatic patients and healthy adults using maximal expiratory indices [PDF]
, 1989 The selection of effective maximal expiratory was evaluated using discriminant analysis of asthmatic patients and healthy adults in this review. Maximal expiratory volume-time and flow-volume (MEVT and MEFV) curves were drawn for young non-smoking ...

Advanced Functional Materials, EarlyView.Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

Maximal expiratory flow-volume patterns in airway allergy. [PDF]
, 1983 We considered upper and lower airway allergies as different phases of airway allergy and MEFV patterns to vary according to the intensity of airway obstruction in maximal expiratory flow-volume and volume-time tests on fourteen patients with nasal ...

Fiber‐Based Wearable Electronics as Adaptive Biointerfaces for Healthcare Applications
Advanced Functional Materials, EarlyView.Fiber‐based wearable electronics have been extensively studied as adaptive healthcare biointerfaces. In this review, we classify and introduce fiber‐based systems according to biointerface design, conductive materials, transduction mechanisms, and healthcare applications, and provide a perspective on their translation toward reliable, continuous ...

Computerized method for analyzing maximum and partial expiratory flow-volume curves
, 1975 Computerized instrumentation and software have been developed to obtain maximum expiratory flow-volume (MEFV) and partial expiratory flow-volume (PEFV) curves.

Advanced Materials Technologies, EarlyView.A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...
