Pulse oximeter is a medical device that measures blood oxygen saturation and pulse of patients. Portable pulse oximeters more like a PC-60B2 medical Landon also measure blood volume changes in the skin for a photoplethysmograph. A blood oxygen monitor, the percentage of arterial hemoglobin in the oxyhemoglobin configuration. Generally, the acceptable normal range is 95-100 percent. What makes a portable pulse oximeter, such as PC-60B2 Medical Landon, is particularly effective is that they are the non-invasive measurement instruments that can be done with the patient wherever they go.

Oximeters work in a way that is quite simple. After inhalation of oxygen in the lungs pass into the blood where the oxygen bound to hemoglobin as a means of transport in the blood. The oxygenated blood is then distributed to various tissues throughout the body. oxygen in the blood absorbs light at different levels of deoxygenated blood. A pulse oximeter using properties of light absorption of hemoglobin and the diversity of pulsations of blood flow to measure the oxygen saturation level.

Pulse oximeters consists of two light-emitting diode light sensor and collect the two, which measures the amount of infrared and red light out of the light rays pass through the network. oxygen-rich hemoglobin absorbs more infrared light and hemoglobin without oxygen absorbed more than red light. The pulse oximeter and then calculate the change and provides a digital readout of SpO2 and pulse rate. Digital read and then given to a doctor to assess the amount of oxygen carried in the blood and determine whether the extra oxygen it needs.

Medical factors using pulse oximeter very diverse and varied, including but not limited to respiratory and cardiac problems. a patient’s need for oxygen is the most important element to sustain life, there is no human life evolved without the presence of oxygen. Pulse oximeters are the most accurate and cost-effective way to measure blood oxygen saturation and heart rate, both are very important in controlling many medical illnesses.
