Maximal Inspiratory pressure (MIP) is an important clinical method used to assess respiratory muscle strength. The reliability and reproducibility of this measurement in mechanically ventilated patients is not certain. In 14 stable, mechanically ventilated patients, capable of spontaneous inspiratory efforts, we assessed maximal inspiratory efforts using(More)
In patients with severe expiratory airflow limitation, dynamic hyperinflation often occurs when inspiratory efforts are initiated at a thoracic volume above the relaxation point of the respiratory system. The result is intrinsic positive end-expiratory alveolar pressure (PEEPi). To determine whether PEEPi occurs in ambulatory patients, we measured alveolar(More)
With the advent of small inexpensive peak flowmeters, the at-home monitoring of peak flow rates has become an invaluable aid in the treatment of asthmatic patients. In this study, we evaluated the performance of the MiniWright and Assess peak flowmeters for accuracy and reproducibility. Measurements were made at varying peak flow rates and compared with(More)
Antenna Diversity Wireless engineers are generally familiar with the benefits to be gained of using antenna diversity in cellular base stations, although they are implemented as an overlay to the system and not part of the basic standard. The IEEE also recognizes these benefits and included provisions for primary and auxiliary antenna ports in its family of(More)
