Abstract:
Respiration exercises are an important part in the pulmonary rehabilitation of COPD (chronic obstructive pulmonary disease) patients. Furthermore, previous research has demonstrated that showing respiration pattern helps the patients to improve their breathing skills. We have developed a low cost and non-invasive prototype based on the Wii remote game controller infrared camera to provide BPM (breaths per minute) measurement as feedback. It can also be a comfortable solution without wires, batteries or any kind of electronics but just wearing passive markers. The lab evaluation with 7 healthy individuals showed that this approach is feasible when users are resting of their exercise. The BPM monitored during the tests presented less than 15% of maximum error and the RMSE (root mean square error) was lower than 6% in all the tests. Further research is needed to evaluate and adapt the system for COPD patients. In addition, more work is needed to develop applications that can be built to motivate and guide the users.

Physiological Control of Respiration
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...
Neural Control of Respiration
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...
Assessment of Respiration
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,...
Respiration
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,...

Assessment of Ventilation I: Respiratory Rate
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.
