What is Sleep Apnea?
Types of Apnea
•
Obstructive Sleep Apnea
• Most common form
• Physical obstruction of
airway
A common disorder in which
breathing either stops or is
shallow for any given period of
time while asleep
• Chronic disorder that leads to
poor sleep quality
Central Sleep Apnea
• Our focus
• Underdeveloped brain of
infants forget to tell child
to breathe
• Pauses may last a few
seconds to a few minutes
depending on severity
The Microcontroller
• The Microcontroller is a
small computer on a single
integrated circuit containing
a processor core, memory,
and programmable
input/output peripherals.
• Programmed in C coding
language.
Objective
• Babies
in
hospitals
frequently
die
from
central sleep apnea
• Nurses cannot constantly
check each child
• Our goal is to create a
system that alerts nurses
if apnea sets in
The MSP430
• A mixed-signal
microcontroller family
from Texas Instruments.
• Capabilities include
temperature indicator,
Red/Green LEDs, and
Micro-USB port.
• Capabilities include pH
sensor and Temperature
indicator.
• Applications: Remote
controls, Blood pressure
monitors, Lighting, Kitchen
appliances, and any key
entry product.
Our use of the microcontroller
•
Analyze an electrical
signal to determine
if Sleep Apnea has
set in
Pseudo Code
Clock On
Timer On
Green LED On
Analog-Digital Converter On
Threshold determined
If (voltage >= threshold)
Timer resets to 0
If (voltage < threshold)
Clock continues counting
Loop
When clock count = 10, Red
LED will indicate apnea
