The plethysmograph: a review of recent literature.
There is much research to support the claim that the penile plethysmograph is a reliable and valid method of objectively measuring and assessing the erectile response in male sex offenders. The authors have reviewed some of the most recent literature dealing with this subject. The conclusion is that although the penile plethysmograph is the best objective measure of male sexual arousal and can ...
متن کاملFrequency dependence of specific airway resistance in a commercialized plethysmograph.
Specific airway resistance (sRaw) measured by body plethysmography has been shown to decrease markedly with decreasing breathing frequency when the inspired air is not conditioned to body temperature, atmospheric pressure and saturation with water vapour (BTPS). The phenomenon has been attributed to noninstantaneous gas warming and wetting in the airways. The aim of this investigation was to as...

متن کاملApplications of Infrared Plethysmograph Waveform Time-Frequency Analysis
In the past, when patients were taking computed tomography (CT) scan, the physician usually monitored the patients on-site as a passive way; however, the entire physiological conditions of the patients couldn’t be fully comprehended this way. According to many clinical reports, the heart rates of the patients under tomography may fluctuate because of the injection of contrast medium. A standard...
متن کاملUnrestrained acoustic plethysmograph for measuring specific airway resistance in mice.
An acoustic whole body plethysmograph was developed to estimate specific airway resistance (sRaw) in unrestrained mice. The plethysmograph uses acoustic principles to measure the thoracic breathing pattern and simultaneously measures the airflow entering and/or leaving the plethysmograph. Similarly to traditional methods utilizing a double-chamber plethysmograph, these measurements were combine...
