Capnography is a noninvasive method for monitoring the level of carbon dioxide in exhaled breath (EtCO2) to assess a patient’s ventilatory status. An inherent property of CO2 is to absorb infrared radiation at a very specific wavelength. Capnographs contain sensors that produce infrared sources of blackbody radiation at these wavelengths. These sensors enable the calculation of CO2 levels in a breath sample. Capnographs produce both waveforms and numeric values of the patient’s exhaled breath and are used to identify adverse ventilation events. This helps clinicians diagnose specific medical conditions, leading to important treatment decisions.

Till date I didn’t had any idea about various colors of the noise . I used to consider that noise are of some basic types like shot noise, thermal noise, flicker noise. Basically these are the fundamental noise signal , But we have defined various colors to the noise. Noise has 10 different colors which have been defined and presented below.
The Origin of Biopotentials
(Review of physiological concepts)
• Bioelectric phenomenon is of immense importance to
biomedical engineers because these potentials are routinely
recorded in modern clinical practice.
• ECG (Electrocardiogram), EMG (Electromyogram), EEG
(Electroencephalogram), ENG (Electroneurogram), EOG
(Electro-oculogram), ERG (Electroretinogram), etc. are some
examples of biopotentials.
• As engineers, we should have a good physical insight into the
nature of electromagnetic fields generated by bioelectric
sources. Therefore we could contribute to quantitative solution
of biological problems.
To understand the origin of biopotentials we need to focus on:
• Bioelectric phenomena at the cellular level
