The vast majority of cardiac monitors are electrical devices attached to a patient. The place where electrodes are placed is usually cleaned and shaved thoroughly. In some cases an arm cuff is used as well, when the blood pressure is monitored.
Such monitors provide a visual display of the patient’s parameters. Some of them are set to sound an alarm in case any of the parameters changes outside of the range that is determined by a physician.
There is a whole set of different parameters, including:
- arterial blood oxygen saturation
- cardiac output
- intravascular pressures
- noninvasive blood pressure
- blood temperature
The equipment that is generally required for continuous monitoring includes the cardiac monitor and cables, pressure transducers and electrode patches, arterial blood saturation probes and a pulmonary artery catheter.
