Comparative analysis of physiologic parameters in mechanically ventilated and spontaneously breathing sheep
We have acquired large datasets during in-vivo trials to illuminate the etiological relationships driving the development of Hydrocephalus, a neurodegenerative disease. To better process our results, this project's goal is to acquire a better quantitative understanding between spontaneous and mechanically ventilated breathing in the mean, pulse, and frequency domain.

Hydrocephalus is a disease characterized by an excess accumulation of cerebrospinal fluid (CSF). This accumulated CSF can lead to a slew of clinical sequelae, including impaired gait, memory loss, incontinence, etc. To better understand the precursors to this disease, we have conducted acute sheep trials with a slew of simultaneously recorded measurements to acquire a comprehensive understanding of how pressures relate. There isn't a defined consensus on how mechanical ventilation impacts these pressures when compared to the spontaneously-breathing counterparts. This project will quantify these variations over the time and frequency domain to acquire a case-specific understanding that we can then use to make our derived results more clinically relevant.

First, you will become acquainted with our wealth of data across 6 unique trials. This data includes intracranial (brain) and intrathecal (lumbar spine) pressure, carotid and femoral arterial, central and jugular venous, and abdominal pressures. Then, key metrics will be defined to compare datasets containing mechanically ventilated and spontaneously breathing sheep - which will be used to quantitatively compare the datasets. Finally, conclusions will be derived based on the findings.

Experience in coding (Python is preferred but MATLAB is also okay) and also are aware of standard signal processing techniques (filtering, frequency transformations, etc). An analytical mind is a plus and an ability to work with large datasets and recognize patterns within.
