Theoretical Considerations of Pulmonary Percussion Notes
نویسنده
چکیده
The subject may best be prefaced by a brief consideration of a few characteristics of sound production, especially of those that apply to the percussion of a membrane. When a drum is struck a certain note is produced, and the four cardinal characteristics of this note are pitch, intensity, quality and duration.

Introduction & Objective: passive respiratory exercises are used to prevent from accumulation of secretions, lung collapse and the incidence of ventilator-associated pneumonia in ICUs. This study is aimed to compare the effects of manual percussion and mechanical vibrations on cardiopulmonary functions of mechanically ventilated patients. Materials &Methods: This randomized crossover clinical...

متن کاملTheoretical percussion force of the periotest diagnosis.
The Periotest percussion force acting on a dental implant was estimated by assuming a mass-spring-dashpot model of the implant-bone system constructed on the basis of a clinical experiment. A theoretical value of about 10 N, comparable to hitherto reported experimental values, was obtained for an osseointegrated implant of about 1 g. The percussion force would probably be smaller for a heavier ...
متن کاملA comparison of manual to mechanical chest percussion for clearance of alveolar material in patients with pulmonary alveolar proteinosis (phospholipidosis).
To our knowledge, there are no studies that compare the effectiveness of manual chest percussion (MN), mechanical chest percussion (MC), and no percussion (NP) for removing the proteinaceous material found in the alveoli of patients with pulmonary alveolar proteinosis (PAP) while undergoing whole-lung bronchopulmonary lavage (BPL). We analyzed the optical densities (OD) of 27 bottles of effluen...
