BMED Capstone (Pulse Ox)
Transcript of BMED Capstone (Pulse Ox)
Background & Scope
Limitations & Future Work
does not adhere to the surface of the polymer and needs to be covalently bonded
cannot connect to enterprise network; must rebuild hardware to commercialize the device
Attachment probe and dye

OxiCore: The Fetal Monitoring Device
From a mother's perspective...
85% used fetal heart rate monitoring
Introduction & Background
Infection, future miscarriages, maternal mortality
32% delivered via c-section (many deemed unnecessary )
Current Clinical Standard for internal fetal monitoring is the Fetal Scalp Electrode (FSE)
Category II tracings, 80% of physicians do not agree on heart rate evaluation
Fetal heart rate alone is insufficient for the determination of fetal distress (lacking proper oxygen)
The current clinical standard for fetal monitoring, the fetal scalp electrode (FSE), gives many false positive readings for improper oxygenation of the fetus during labor.
Relevant Functions & Constraints
Viewing one or more of these parameters over time gives the physician more information than the FSE.
Limited to only the presenting part of the fetus
Cervix must be dilated at least a centimeter (monitor DURING labor)
Cost : Probe ~ $15.00
How are the oximetry and pH subsystems integrated physically?
How is the probe attached to the fetal scalp?
Circuit Schematic & Housing Unit
Dimensions based off of minimal cervical dilation (3-5 cm)
Encrypted & Secure (HIPAA Compliant)
Accessible and dynamically presented for different devices
Presents physician with multiple measured parameters over time

Operate for at least 72 hrs
Sensing probe must:
pH range: 3.00-8.00
6.0 - 8.0 with 1/100 unit accuracy
%O2 range: 30%-90%
while in use.
Be in contact with blood
(for pH sensing)
56% higher chance of infant mortality in the first 4 weeks
pH Bifurcated Cable
"I feel guilty that maybe I am being ungrateful for an otherwise successful delivery. What a lot of people don't realize is that you can be happy and grateful while also being very sad about the loss of the birth experience you wanted and planned for..."
"Does anybody who has had a C-section feel down? I wish I did not feel this way..."
"I feel the same. I had an emergency C-section. I still cry when I think about it now and it was 10 weeks ago..."
