Monitoring Breathing Signals in Sleep Apnea Patients Using LabVIEW
Allison CampbellBearden High School
Young Scholars Summer Program23 July 2015
University of Tennessee
Sleep Apnea Defined:
• Disruption of breathing during sleep
• Chronic disorder
• Disruptions may last up to a few seconds to
several minutes depending on severity
5-2
Types of Sleep Apnea:
Obstructive Sleep Apnea
• More common type
• Temporary collapsed airway
Central Sleep Apnea
• Our focus
• Underdeveloped brain of infant
neglects to send signals to the
respiratory system during sleep
5-3
The Problem:
• Sleep Apnea is a common, life-threatening health
issue.
• Infants often succumb from Central Sleep Apnea,
and nurses and hospital staff cannot constantly
monitor each and every child.
One of the leading causes of death infants

Current Treatment

Mandibular Advancement Device (MAD)
Tongue Retaining Device
Objective
To create a system that alerts caregivers when
pediatric patients’ breathing signals are shallower
than normal.

• Defined: A Visual
Programming System
• Used for Data Acquisition

Project Overview
5-8
In this project I developed a program on the Block Diagram
(back panel) that will continuously monitor the simulated breathing
signals (from the DAQ card-waveform generator) of sleep apnea
patients. If a signal is not detected for longer than 20 seconds, the
code will trigger an alarm that would awake the sleep apnea
conditioned child in the hospital bed. I created a LabVIEW front panel
from where the caregiver in the hospital can easily monitor the child’s
current breathing signals.

Why is the Program Important?
• Sleep Apnea affects 48 million people nationwide.
• It is a chronic disorder that may lead to other
serious health risks, such as stroke.
5-11
The Path Forward
• Pairing this program with the proper sensors to
attach to the patient and connected to the monitor
• Clinical Trials
• Using this method to monitor other types of
patients5-12
