Tracheal and lung sounds repeatability in normal adults

Tracheal Sounds Acquisition Using Smartphones

Tracheal sounds have received a lot of attention for estimating ventilation parameters in a non-invasive way. The aim of this work was to examine the feasibility of extracting accurate airflow, and automating the detection of breath-phase onset and respiratory rates all directly from tracheal sounds acquired from an acoustic microphone connected to a smartphone. We employed the Samsung Galaxy S...

Tracheal sounds in upper airway obstruction.

A boy with subglottic narrowing secondary to laryngotracheitis presented with noisy breathing. Acoustic measurements of tracheal sounds at standardized air flows correlated well with the clinical course and with spirometric assessments. This indicates the potential value of respiratory sound characterization in patients with upper airway obstruction.

Evaluation of executive functions and emotional impulsivity in Adults with ADHD and normal Adults

The present study aimed to compare the executive functions and emotional impulsivity between adults with hyperactivity disorder/attention deficit and normal adults. This research was ex post facto design. The study population was patients referred to the center of counseling and psychotherapy in Tabriz. The sample consisted of 60 subjects (30 adults with hyperactivity disorder/attention deficit...

Lung Sounds

Abnormal lung sounds in patients with asthma during episodes with normal lung function.

Even in patients with clinically stable asthma with normal lung function, the airways are characterized by inflammatory changes, including mucosal swelling. In order to investigate whether lung sounds can distinguish these subjects from normal subjects, we compared lung sound characteristics between eight normal and nine symptom-free subjects with mild asthma. All subjects underwent simultaneou...
