Monitoring
The appropriate selection of the specific physiologic parameters that should be monitored during the MRI procedure is vital for patient safety. They consist of MRI safe Pulse oximeter, Electrocardiograph and respiratory bellows or pneumatic capsules.
This physiologic parameter is measured using pulse oximetry, a monitoring technique that measures the oxygenation of tissue. Due to which oxygen saturated blood absorbs differing quantities of light compared with unsaturated blood, the amount of light that is immersed by the blood can be used to calculate the ratio of oxygenated hemoglobin to total hemoglobin and shown as the oxygen saturation. Moreover, the patient's heart rate may be calculated by taking the frequency that pulses occur as the blood travels through the vascular bed. Thus, this pulse oximeter can be used to determine oxygen saturation and pulse rate on a nonstop basis by taking measurement of the transmission of light through a vascular site such as the ear lobe, finger-tip, or toe. The used of fiber-optic technology have been established through this pulse oximeter to acquire and transmit the physiologic …show more content…

Monitoring the patient's electrocardiogram (ECG) in the MRI environment is mostly challenging because of the inherent distortion of the ECG waveform that happens using MR systems operating at high field strengths. The use of proper ECG electrodes for example those tested and estimated to be acceptable for patients is required to confirm patient safety and appropriate recording of the electrocardiogram in the MRI environment. Therefore, ECG electrodes have been specifically established for use during MRI procedures to protect the patient from possibly hazardous conditions. These ECG electrodes were also designed to reduce MRI-related
