Patient Monitoring Equipment: Moving Toward an Optimal Design

Patient Monitoring Equipment: Moving Toward an Optimal Design

The growing ability to connect multiple technologies, devices, and the data they generate is likely to shape the future of healthcare.

Demand for real-time continuous data, including personal health information, early warning scores, and alerting when a patient’s condition is deteriorating, is driving the market for complete monitoring systems in hospital and home care settings globally.

Patient monitoring has evolved significantly since its inception. Not too long ago, remote monitoring represented a convenient alternative to frequent visits to the arrhythmia clinic. However, breakthrough advancements in technology have now enabled remote patient monitoring (RPM), virtual patient–clinician interactions, fitness, and activity tracking through passive home and body sensors. The growing ability to connect multiple technologies, devices, and the data they generate is likely to shape the future of healthcare. The latest technologies in patient monitoring equipments allow to record and transmit digitized vital signs in the form of signals from an individual device to the computer or handheld personal digital assistant (PDA) of a healthcare professional instantly, thereby reducing the duration of evaluation and treatment. The use of multiparameter patient monitoring equipment is transitioning from ICU units to transport and mobile applications. Vendors have established a new paradigm in the connectivity of monitoring devices by incorporating wireless technology, which allows devices to communicate directly and securely to the application downloaded onto a patient’s smartphone. Traditional remote monitoring requires bulky handheld or bedside transmitters, which limit patient mobility. The new interactive mobile application replaces these passive transmitters and empowers patients to participate in their own care.

In the near future, expect medical professionals to develop more holistic applications for patient monitoring technology. Instead of targeting a single condition, such devices could track patient health at a large scale – think of this as a yearly physical examination performed on a rolling basis, with no need for an in-office check-up until an issue actually arises.

If these technologies continue to advance at their current pace, one will likely see a widespread adoption across patient demographics in no time at all. As these monitoring applications become more widely implemented, they are poised to revolutionize both quality of life and quality of care one patient at a time.

 The Future is Already Here: Why You Should Choose Modular Patient Monitors

Patient monitors are found in virtually every care setting in a hospital especially so in critical care units where the patient’s health condition is monitored intensively for timely intervention. Monitors allow caregivers to track all relevant clinical parameters on a single dashboard to get a holistic view of the patient’s clinical condition. The right monitor would enhance the healthcare provider’s efficiency by predicting risk ahead of time.

Monitors are either pre-configured or modular. Most pre-configured monitors and associated central monitoring systems are economical in the short term but prove to be inflexible to accommodate other critical parameters and expanding needs. Therefore, when the hospital wants to upgrade and buy modular monitors with advanced features and parameters, many a times the preconfigured monitors end up being redundant because the central station supporting modular monitors and even accessories are different.

With advancing technologies and newer devices being brought into clinical practice, preconfigured monitors would prove to be a short-sighted solution. Typically, a pre-configured monitor from the same manufacturer will not have the same set of must-have clinical features such as multilead arrhythmia monitoring as they would have in their modular solution.

Modular monitors allow scalability in terms of connectivity to HIS, charting, and web viewing solutions as well as parameters to be measured. In an ICU it is very important to have modularity of parameters such as EtCO2 for patients with an artificial airway and invasive blood pressure measurements. Some studies have shown that failure to use capnography in patient’s dependent on an artificial airway contributed to more than 70 percent of ICU related deaths or persistent neurological injury.

Modular monitors allow better work flow between beds and aids in correct monitoring of patients from central stations, while preconfigured monitors require resetting parameters and changing service menu settings by the biomed engineer every time the monitor is moved across beds (because all monitors in the ICU do not have the same configuration) thus adversely impacting workflow in an already stressed ICU.

It is a wise decision to invest in a modular type of monitor that fulfills the clinicians’ requirements for now and for the future, delivering better healthcare outcomes and providing the right return of investment.

 The Past, Present, and Future

Patient monitoring has been around since the dawn of mankind, though there was no umbrella term for the methods used to track heart rate, body temperature, breath rate, and other factors. Compared to the 1600s when spirit thermometers were
used to measure body temperatures and pulse rate was timed with the help of a pendulum, patient monitoring has come a long way.

Today, technological advancements have made it possible to have sophisticated and detailed analysis, compact equipment etc., and have also led to the development of specialized monitoring systems – designed to suit healthcare professionals’ specific requirements like cardiac monitor which includes basic parameters with cardiac output, IBP; anesthesia monitor which can measure the depth of anesthesia, neuromuscular transmission etc.

The introduction of modular technology has enabled professionals to change the features of their monitor by simply changing the modules as per requirement. However, this was all in the past. What we look forward to now is to know what the future has in store for us.

Talking about patient comfort, remote patient monitoring will gain more prominence. As of 2016, India’s aging populace comprises 13.39 percent of the total population and is expected to go up in the coming years. This gives rise to the need for monitoring patients where they live. Telemonitoring in India is not yet commonplace, despite its adoption worldwide. In those rare cases which require remote monitoring, medical institutions still rely on old technologies. The very near future will see a change in the way a remote patient’s data is transmitted, mainly through a 3G (and hopefully 4G) cellular network. Also, transport patient monitors will be further lightweight with massive battery backup.

For medical institutions, acquiring a patient monitor is a huge investment. Rapid technological advancements result in a discovery that attempts to change the face of healthcare. At the same time, it also increases the cost of monitors. This is where professionals end up choosing cheap alternatives that are neither reliable nor a medical marvel. Subsequent years need to focus on lowering the price without compromising on technology.

To conclude, monitors are a prime source for doctors to understand their patients’ live condition. These and various other developments in patient monitoring technology have the potential to improve medical outcomes. Here is to hoping that 2018 is the year of significant breakthroughs.

Recent Trends in Blood Pressure Monitoring Devices

India’s healthcare spend as a percentage of GDP (2.5 percent) is still amongst the lowest globally and there are significant challenges to be addressed, both in terms of accessibility of healthcare services and quality of patient care at an affordable price. In the recent years, the burden of cardiovascular diseases has increased exponentially in emerging economies creating a huge need for diagnostic equipment of good quality that can help in early detection and diagnosis of disease and thus facilitate suitable and timely treatment.

Patient monitoring is a dicey game wherein monitoring remotely becomes immensely important as the symptoms may set in well after the patient leaves the physician’s set up. Just like Holter monitors being used in patients with suspected cardiac arrhythmias, the need for remote continuous monitoring is the need of the hour when it comes to blood pressure monitoring.

The traditional auscultatory measurement of BP has limitations such as momentary BP values that are influenced by external circumstances, observer bias, or whitecoat hypertension. Many patients with controlled hypertension at the medical settings show BP levels above the thresholds of out of the medical settings and vice versa.

Recent advancements in technologies have helped us solve exactly this problem by helping us measure BP continuously within a 24-hour time period. An ambulatory blood pressure monitor (ABPM) is a device that measures blood pressure, tracks the changes, and reports the trend. An ABPM can be provided to the patient to carry along and thus helping with 24-hr BP measurement outside of a standard hospital or outpatient care setting. ABPM correlates more closely with end-organ complications than BP levels measured in the clinic. Especially for patients with uncontrolled hypertension, ABPM turns out to be a handy tool. With the varying levels of BP measured over different time intervals, it gives as many data points as possible to the physician to diagnose the conditions and circumstances that lead to varying levels of blood pressure.

Newer technologies are on the rise which helps consumers measure BP through a wrist band. While the increasing trend in monitoring is welcome, whether or not a wrist type measurement will be accurate remains to be tested.

 Clinical Assistive Applications: An Ideal Associate

In today’s scenario, patient monitoring in high-acuity areas provides enormous data to the clinicians for decision making but it is troublesome to draw inference regarding its full strength from this complex data. As the interpretation of these complicated and interlinked parameters is a tedious job, so the result is only half of the displayed parameters are taken into account for further diagnosis.

In ICU, the biggest challenge for clinicians is to focus on three important aspects, hemodynamics, ventilation, and sepsis control. Each aspect is flooded with bundles of numerical data, which create a lot of mental workload
to draw a conclusion on implementation in patient treatment.

This problem can be handled in an effective way by transforming these numerical values into more informative visual graphics and step-by-step guided procedures. It is obvious that graphical displays absorb the large amount of data quickly and allow a faster detection of changes in physiologic variables as compared to alignical numerical display. So, this need has created a demand for support tools such as Clinical Assistive applications.

These applications are designed as per clinical workflow in different care areas, which help clinicians to achieve their goal directed therapies in a time saving and convenient way. These tools are meant to track the patient progress, which aids in detecting critical conditions earlier and improving the outcome. CAA tools like graphical representation of ST, QT/QTc analysis, 24 hours ECG summary make a difference in the cardiology segment.

For tracking real time patient progress on the hemodynamic and ventilation front, Hemosight is an ideal companion to trust. SepsisSight, is a vigilance tool which continuously checks the patient data and if required, it prompts the user for necessary interventions indicated by protocol.

Balance of anesthesia display reveals the patient’s response to changes of anesthesia conditions by an intuitive triangle and may help in titrating analgesia requirement of each individual.

These tools are designed with an intention to provide enormous benefits to clinicians in the sense that they allow a check of hundreds of criteria and act as an ideal associate to help in decision making.
