Summary
This study presents a low-cost, non-invasive system using a Wii remote camera to measure breaths per minute (BPM) for pulmonary rehabilitation. Lab tests show feasibility and accuracy for healthy individuals, paving the way for COPD patient applications.
Area of Science:
- Biomedical Engineering
- Rehabilitation Technology
- Respiratory Medicine
Background:
- Respiration exercises are crucial for COPD pulmonary rehabilitation.
- Visualizing respiration patterns enhances patient breathing skills.
- Existing methods may be costly or invasive.
Purpose of the Study:
- To develop a low-cost, non-invasive prototype for measuring breaths per minute (BPM).
- To provide real-time feedback on respiration patterns for rehabilitation.
- To assess the feasibility and accuracy of the system in healthy individuals.
Main Methods:
- Utilized a Wii remote infrared camera for non-invasive BPM measurement.
- Employed passive markers, eliminating the need for wires or electronics.
- Conducted lab evaluations with 7 healthy individuals during resting conditions.
Main Results:
- The prototype demonstrated feasibility for monitoring BPM in healthy subjects.
- Measured BPM showed a maximum error of less than 15%.
- Root Mean Square Error (RMSE) was consistently below 6% across all tests.
Conclusions:
- The developed system is a feasible and accurate approach for BPM monitoring.
- Further research is required to adapt and validate the system for COPD patients.
- Future work should focus on developing motivating and guiding applications for users.

01:23Physiological Control of Respiration
Introduction
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

01:18Neural Control of Respiration
The neural regulation of respiration is a meticulously coordinated process primarily controlled by the respiratory centers located within the brainstem. These centers, composed of specialized neurons, transmit nerve impulses that control the contraction and relaxation of our respiratory muscles.
Respiratory Centers in the Brainstem
Two primary areas comprise the respiratory center: the medullary respiratory center in the medulla oblongata and the pontine respiratory group in the pons. The...

01:23Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

Overview of the Respiratory System and Energy Production
Energy production in the human body is primarily fueled by oxidation, a process where food molecules are burned by combining with oxygen to produce carbon dioxide and water. This vital metabolic process sustains life, and is supported intricately by the respiratory system.
Structure and Function of the Respiratory System:
The respiratory system is a complex network of structures that includes the nose, oropharynx, larynx, trachea,...

01:24External and Internal Respiration
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
