Arterial pulsation which had long been studied for estimation of blood pressure or mean blood pressure was replaced by the measurement of systolic and diastolic blood pressure using Korotkoff sound detected by stethoscope in the beginning of the previous century. In the meantime, vast of modern knowledge of human hypertension from epidemiology to randomized clinical trial had been built on the Korotkoff sound and stethoscope methodology. Hypertension is very special clinical entity in terms of the diagnosis is solely dependent on the manual blood pressure measurement by a physician or nurse...

The aim of this study was to establish predictors for successfully planned extubation, which can be followed by medical personnel. The patients who were admitted to the adult intensive care unit of a tertiary hospital and met the following criteria between January 2005 and December 2014 were collected retrospectively: intubation > 48 hours; and candidate for extubation. The patient characteristics, including disease severity, rapid shallow breath index (RSBI), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), cuff leak test (CLT) before extubation, and outcome, were recorded...

 We utilized the information and communication technology to develop the physical assessment (PA) learning materials in the virtual experience type. This learning material consists of two parts which include case learning and basic learning. We created example scenarios about various conditions that a pharmacist may experience in medical scenes such as in a hospital ward, community pharmacy, home, and drugstore. Illustrations of a virtual patient's avatar before and after taking the medicines were incorporated in the learning materials...

Today it is well demonstrated that stethoscopes can be as contaminated as hands, which are a recognized source of Health-Care Associated Infections (HCAIs). Ultraviolet C (UVC) light has proven disinfection capacity and the innovative UVC technology of Light Emitting Diode (LED) shows several potential benefits. To verify whether the use of UVC LEDs is effective and reliable in stethoscope membrane disinfection after prolonged use, a pre-post intervention study was conducted. A total of 1668 five-minute cycles were performed on two UVC LEDs to simulate their use; thereafter, their disinfection capacity was tested on stethoscope membranes used on a previously auscultated volunteer...

Mobile phones, due to their audio processing capabilities, have the potential to facilitate the diagnosis of heart disease through automated auscultation. However, such a platform is likely to be used by non-experts, and hence, it is essential that such a device is able to automatically differentiate poor quality from diagnostically useful recordings since non-experts are more likely to make poor-quality recordings. This paper investigates the automated signal quality assessment of heart sound recordings performed using both mobile phone-based and commercial medical-grade electronic stethoscopes...

Acoustic source localization without knowing the velocity profile in anisotropic plates is still one of the most challenging areas in this field. The current time-of-flight based approaches for localization in anisotropic media, are based on using six high sampling sensors. The number of sensors and the corresponding large amount of data, would make those methods inefficient in practical applications. Although there are many different non-time-of-flight based approaches such as machine learning, or soft computing based methods that can be used for localization with a less number of sensors, they are not as accurate as time-of-flight based techniques...

BACKGROUND: Non-critical medical devices, as stethoscopes, have long been considered as vectors in microorganisms' transmission. Cleaning standards for non-critical medical equipment are often unclear. This study was designed to assess the attitude of General Practitioners (GPs) towards cleaning their stethoscope and the degree of microbiological contamination of doctor's instrument in outpatient setting. STUDY DESIGN: Observational, crossover study. METHODS: A structured questionnaire was administered to GPs to test their knowledge about medical instrument's cleanliness recommendations and the surface of the diaphragm of their stethoscopes was analyzed for bacteriological isolates using mass spectrometry technique...

OBJECTIVE: To determine differences in the recontamination of stethoscope membranes after cleaning with chlorhexidine, triclosan, or alcohol. METHODS: Experimental, controlled, blinded trial to determine differences in the bacterial load on stethoscope membranes. Membranes were cultured by direct imprint after disinfection with 70% isopropyl alcohol, 1% triclosan, or 1% chlorhexidine and normal use for 4 hours. As a baseline and an immediate effect control, bacterial load of membranes without disinfection and after 1 minute of disinfection with isopropyl alcohol was determined as well...

BACKGROUND: Access to asthma specialists is a problem, particularly in rural areas, thus presenting an opportunity for management using telemedicine. OBJECTIVE: To compare asthma outcomes during 6 months in children managed by telemedicine vs in-person visits. METHODS: Children with asthma residing in 2 remote locations were offered the choice of an in-person visit or a telemedicine session at a local clinic. The telemedicine process involved real-time use of a Remote Presence Solution (RPS) equipped with a digital stethoscope, otoscope, and high-resolution camera...

An intracranial dural arteriovenous fistula(dAVF)was incidentally detected in a 39-year-old man during a medical checkup. Except for a mild episode of pneumonia at the age of 22 years, his medical history was unremarkable. He had no family history of hereditary hemorrhagic telangiectasia(HHT). The dAVF was treated radically via ligation of the fistula, without any complications. Postoperative angiography demonstrated that the dAVF had completely healed, but showed an aberrant, dilatated, and tortuous internal mammary artery...

Many mobile phone or tablet applications have been designed to control cardiovascular risk factors (obesity, smoking, sedentary lifestyle, diabetes and hypertension) or to optimize treatment adherence. Some have been shown to be useful but the long-term benefits remain to be demonstrated. Digital stethoscopes make easier the interpretation of abnormal heart sounds, and the development of pocket-sized echo machines may quickly and significantly expand the use of ultrasounds. Daily home monitoring of pulmonary artery pressures with wireless implantable sensors has been shown to be associated with a significant decrease in hospital readmissions for heart failure...

BACKGROUND: Interventions to improve neonatal resuscitation are considered a priority for reducing neonatal mortality. In addition to training programs for health caregivers, the availability of adequate equipment in all delivery settings is crucial. In this study, we assessed the availability of equipment for neonatal resuscitation in a large sample of delivery rooms in Vietnam, exploring regional differences. METHODS: In 2012, a structured questionnaire on 2011 neonatal resuscitation practice was sent to the heads of 187 health facilities, representing the three levels of hospital-based maternity services in eight administrative regions in Vietnam, allowing national and regional estimates to be calculated...

BACKGROUND: Smartphones are ubiquitous and commonly used as a learning and information resource. They have potential to revolutionize medical education and medical practice. The iDoc project provides a medical textbook smartphone app to newly-qualified doctors working in Wales. The project was designed to assist doctors in their transition from medical school to workplace, a period associated with high levels of cognitive demand and stress. METHODS: Newly qualified doctors submitted case reports (n = 293) which detail specific instances of how the textbook app was used...

BACKGROUND: This study compared the diagnostic efficacy of the common suspended diaphragm stethoscope (SDS) with a new extensible diaphragm stethoscope (EDS) for low-frequency heart sounds. METHODS AND RESULTS: The EDS was developed by using an ethylene propylene diene monomer diaphragm. The results showed that the EDS enhanced both the volume and quality of low-frequency heart sounds, and improved the ability of examiners to auscultate such heart sounds. CONCLUSIONS: Based on the results of the sound analysis, the EDS is more efficient than the SDS...
