Patient Monitors: What are their components, uses and how are they providing quality patient care?

Consistent developments and innovations in sensor and interconnect technology have revolutionized methods to monitor patient wellbeing in medical establishments. As the methods become easier for healthcare providers, the devices are now much more complex to their predecessors.

Let’s analyse what are the different components of a patient monitor, their uses and how they are providing quality health care.


What is a patient monitoring system?

Patient monitoring systems are any set of systems and/or processes that enable healthcare providers to monitor a patient’s health.


What are the different types of patient monitoring systems?

There are two main types of patient monitoring systems. They are as follows:

  1. Single Parameter Monitoring Systems:

These kind of patient monitoring systems measure the blood pressure of the human body, SpO2, ECG etc.

  1. Multi Parameter Monitoring Systems:

These patient monitoring systems monitor multiple critical physiological vital signs like respiration rate, electro cardiograph, blood pressure etc. Within Multi Parameter (or Multi Para) patient monitors, there are different types of systems like 2 Para Patient Monitor, 3 Para Patient Monitor, 5 Para Patient Monitor and 7 Para Patient Monitor.


What are the components of a patient monitoring system?

Each patient monitoring system could be unique, i.e. a pulse oximeter will not have the same construction as a glucose monitor. However, the components of a patient monitoring system are classified into three general categories: the actual patient monitoring device, the capital equipment, and the software.


Patient monitoring device:

Although, the term “patient monitoring device” refers to the complete monitoring system, but for understanding purposes the piece of equipment that makes contact with the patient can be referred to as the patient monitoring device.

The patient monitoring device generally contains a sensor for capturing important patient information and an interconnect solution that transmits the information to the capital equipment.


For example, in a pulse oximeter the piece that clips to the patient’s finger and senses and transmits their pulse to the capital equipment is an example of the patient monitoring device component.


The Capital Equipment

The patient monitoring device collects important patient data, that data is then sent to the equipment where it is processed, stored, and displayed. The equipment that processes, stores and display this data is called the capital equipment.


Most capital equipment deployed in patient monitoring apply a complex interconnect system of connectors, PCBs, and wire harnesses as well as some kind of screen/monitor where the data is shared in a useable format. A computer screen that exhibits the information of a patient’s ECG P-Wave is an example of the capital equipment used in a patient monitoring system.


The Software

After the patient data is transmitted from the device to the capital equipment, it needs to be processed. While the hardware gathers the data, the software makes the data useable. The drivers, applications, and programs that process, store, and visually transform the information are vital parts of any patient monitoring system.


What are the uses and applications of patient monitoring systems?

There are a number of applications where patient monitoring systems are used.

Patient monitoring systems are crucial to any surgical operation inside hospital and clinical walls.

During an operation, the surgeon must have continuous access to a patient’s vital signs to mitigate the risk of something negative happening. In an operating room, you will typically find some form of thermometer to track a patient’s temperature, a pulse oximeter to measure oxygen levels, a capnography machine for monitoring CO2 levels, and a sphygmomanometer to measure blood pressure.

After an operation, many of these same monitoring devices are used by doctors, nurses, and other healthcare providers to ensure that post-operative recovery is going smoothly. Beyond the clinical setting, remote patient monitoring systems are used in a variety of applications, such as diabetes care.

Glucose monitoring devices have been used outside of the hospital by diabetes patients for years, enabling both the patient and their physician to prevent dangerous health events.


How are patient monitoring systems improving patient care?

During treatment, it is highly imperative to continuously monitor the vital physiological signs of the patient. Patient monitoring systems hold an important position in patient care. The consistent developments in technology not only help us in transmitting the crucial physiological signs to healthcare workers and also simplifies the measurement and therefore results in raising the monitoring efficiency of patients. Multi-parameter Patient Monitoring Systems are used to transmit vital data like electro cardiographs, respiration rate, blood pressure etc.

Medical treatments delivered in the intensive care unit make it necessary for constant monitoring of patients. For constant observation of the patient, patient monitoring systems provide continuous visibility of the subject’s physiological condition and provide immediate treatment whenever required.


Patient Monitoring systems are all around us, and they are highly adaptable in the medical establishment. Used in all kinds of treatments, if you are looking to buy patient monitors at best price online, then you must explore the extensive range of medical devices and equipment on Medikabazaar.
