A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery.
Various other methods to measure respiratory rate are commonly used, including impedance pneumography, [4] and capnography which are commonly implemented in patient monitoring. In addition, novel techniques for automatically monitoring respiratory rate using wearable sensors are in development, such as estimation of respiratory rate from the ...
The pulse oximeter is a small device that clips to the body (typically a finger, an earlobe or an infant's foot) and displays its reading, or transfers it to another device. Oxygenated and deoxygenated hemoglobin differ in absorption of light of different wavelengths.
An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rate. Monitoring of vital parameters can include several of the ones mentioned above, and most commonly include at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate.
Measuring the dissolved oxygen through a multi-parameter photometer Oxygen saturation (symbol S O 2 ) is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium at the given temperature.
RR: respiratory rate blood pressure measured with a specific sphygmomanometer relative risk RRMS relapsing-remitting multiple sclerosis: RRP: Recurrent Respiratory Papillomatosis: RRR: regular rate and rhythm (see pulse) RRT Renal replacement therapy: r/r/w: rales, rhonchi, wheezes (lung sounds) RS cell: Reed–Sternberg cell: RSB: Right ...
[1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3] A conventional pulse oximeter monitors the perfusion of blood to the dermis and subcutaneous tissue of the skin. Finger pulse oximeter. With each cardiac cycle the heart pumps blood to the periphery. Even though ...
