A unique and ideal integration of wavelet-based total variation (WATV) empirical Wiener denoising method is proposed in this article to significantly enhance the signal-to-noise ratio (SNR) while preserving characteristics a lung sound signal. While individual filters based on single basis function have been employed past, outcome has unsatisfactory because only significant (signal) wavelet coe...

a 21-year-old man was brought to the emergency department due to multiple trauma (mt) caused by a motor car accident (mca). on arrival, the patient was intubated by prehospital emergency medical services (ems) and had a glasgow coma scale (gcs) score of 6 on 10 (due to intubation, verbal score was omitted). physical examination revealed blood pressure of 150/70 mmhg, oxygen saturation (o2sat) o...

Although life saving, mechanical ventilation can cause complications such as ventilator-induced lung injury and bronchopulmonary dysplasia in very preterm babies. The ventilator-induced lung injury is multi-factorial. There has been an introduction of a number of newer forms of mechanical ventilation, which are aimed to reduce such complications. These are based on sound physiologic principles ...

A patient with pulmonary alveolar proteinosis underwent whole lung lavage of the right lung. Lavage of the left lung was not immediately possible because of severe hypoxemia. Three days later, after correction of hypoxemia, we re-attempted the left lung lavage. However, the patient had severe hypoxemia (SpO2 < 80%) within a few minutes of performing right one lung ventilation (OLV). On bronchos...

introduction: the respiratory system is both a route of entry and exit for toxins and injurious agents, as well as being a target for chemical substances and pathogens. therefore, an understanding of the structure and function of the migratory cell populations of pulmonary tissues including alveolar macrophages is central in a number of important disease processes. this study aimed to identify ...

During slow inflation of lung lobes, we measure a sequence of short explosive transient sound waves called "crackles," each consisting of an initial spike followed by ringing. The crackle time series is irregular and intermittent, with the number of spikes of size s following a power law, n(s) proportional, variants(-alpha), with alpha=2.77+/-0.05. We develop a model of crackle wave generation ...
