Active clinical trials for "Signs and Symptoms, Respiratory"

This cross-sectional survey study is intended to describe the characteristics of adults in 4 US states with regards to respiratory symptoms and tobacco exposure, utilizing an existing state-administered, CDC overseen Behavioral Risk Factor Surveillance System telephone health survey. The primary goal of study is to describe the sociodemographics, health behaviors, and presence of chronic diseases in persons with or at risk of having chronic obstructive pulmonary disease.

To evaluate the level of control of Asthma (GINA : controlled, partially controlled, not controlled) of asthmatic patients consulting their general practitioner for a seasonal increase of respiratory symptoms (high and / or low) whether an inhaled corticotherapy is taken or not.

The VRI technology provides a radiation free dynamic image of the lung, by using a combination of well-known technologies, i.e. acoustic sensors, and a proprietary algorithm. The aim of the study is to determine if the VRI examination may contribute to the diagnosis and follow up of pneumonia in children, and therefore reduce the number of chest radiographs and the exposure to ionizing radiation. Children referred by ED for chest x-ray,for the evaluation of pneumonia, will undergo VRI as well. The two modalities will be read independently and then the findings will be compared, in order to asses the potential role of the VRI to the management of pneumonia in children.

The investigator intend to perform an observational study, by adding Respiratory Rate monitoring to an already existing Patient SafetyNet system with SpO2 (Oxygen Saturation) and PR (Pulse Rate) monitoring. RRa will be blinded to the clinicians and all RRa alarms will be deactivated. Retrospective analysis of the observational data collected will be utilized to evaluate the potential benefits of additional continuous respiratory rate monitoring.

The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
