Comparing Diaphragm Tissue Between Healthy and Ill Patients

The human diaphragm is one of the primary muscles used in respiration, contracting and expanding to control breathing. To measure how much diaphragms move for critically ill patients (in an Intensive Care Unit) compared to diaphragms in a healthy subject, patients at “Papageorgiou” General Hospital in Thessaloniki, Greece were measured using Tissue Doppler Imaging (TDI). TDI uses electrocardiography to measure tissue velocity, and were measured in conjunction with Polydispersity index (PDI), which tracks the molecular weight of gas released, in this case each breath out. PDI was tracked in this study using a TSD104A Pressure Transducer.

Measuring how Stress Affects Respiration with Kinect & BIOPACMeasuring Pulmonary Function with BIOPAC

Psychological stress is a well known trigger to affect respiration, or breathing rate. This study induced psychological stress in subjects and measured their reactions using a Microsoft Kinect depth sensing camera, commonly used as a periphery device for the Xbox game console. True respiration was measured using BIOPAC’s wireless respiration transducer and belt connected to an MP-series Data Recorder.

Associating Neural Activity with Suicidal/Self Harm Tendencies

Existing research shows that there are specific, similar cognitive states and behavioral traits for people at risk for self harm or suicide. While most of these traits (e.g. depression, anxiety, and other common indicators) can often be readily diagnosed, researchers wonder if there are deeper cognitive patterns that can be identified as commonalities between those deemed at-risk. A large study was run utilizing functional near-infrared spectroscopy on the prefrontal cortex during a series of cognitive tests.
