Going to a hospital for vital care can be unpleasant and burdensome, as it is a stressful place, always crowded, and sufferers need to wait before care. The healthcare sector is always interested in new developments that can be used to improve patients’ care and quality of life.

Providing high-quality medical care requires close corporation with many entities and it is also an expensive and time-consuming process. Adding to that medical staff shortage, the ever-increasing aging population, and the growing number of patients with chronic diseases make the task more difficult.

Moreover, during consulting, there are lots of wires, tapes, and Velcro to hold sensors making it difficult and uncomfortable to move. Additionally, the number of tests that can be performed at a time remains limited.

The aim of medical providers is to reduce readmission, shorten hospital stays and improve outcomes. And to achieve that a solution is necessary to effectively monitor and engage high-risk cases. And the solution may lie in the ever-increasing devices in circulation.

Nowadays almost everybody has a mobile phone in their pocket and wearable devices that have some kind of sensor in them. These small wireless communication devices that peoples carry around every day is enabling remote patient monitoring (RPM).

What is remote patient monitoring?

RPM is a subset of telehealth that allows healthcare providers to monitor, analysed, and report patient conditions outside a hospital setting. Remote monitoring enables patients to engage and understand their health conditions.

Remote patient monitoring is a technology that facilitates the performance of medical acts through sensors and communication technologies. RPM makes it possible to analyze health data or patient issues remotely. 

This telehealth service uses devices such as wearables and trackers to collect specific information on the care-receiver’s health. The data is sent to a practitioner for analysis which reduces outpatient visits as well as improves healthcare workflow.

Moreover, RPM allows doctors to interpret data collected by sensors through medical follow-up of a patient. And base on the information, practitioners can make decisions concerning care and treatment. All done remotely.

Why do we need remote patient monitoring?

Remote patient monitoring service helps doctors and nurses monitor their patients remotely, resulting in improved outcomes. It allows caregivers to view a customized dashboard of patient vital signs from anywhere.

This medical monitoring allows physicians to monitor patients remotely, with the use of sensors placed on their bodies or in the environment. It provides practitioners with real-time data on their status, including heart rate, breathing, and blood pressure all done remotely. And this brings on a lot of benefits such as:

  • Collect real-time data
  • Reduced wait time for physician feedback
  • Improved patient comfort and compliance
  • Reduced costs associated with patient care
  • Improve access to healthcare

This system opens the door to new possibilities for clinical teams to assess the condition of sufferers without requiring a physical presence in the same room. Moreover, mobile phones have high-resolution cameras that practitioners can use to see real-time footage about patient health and issue.

When people are unwell or have questions, they can book an online appointment, where a practitioner can access current readings to provide advice. Doctors can enter patient notes, write prescriptions and add other data that pharmacists and specialists can easily access.

Remote monitoring allows healthcare teams to provide smooth routine checkups and give more face-to-face attention where it’s needed most. It enhances the ability of health providers to care for an increased volume of patients without being present in person. 

Remote patient monitoring devices

Blood pressure monitor

Blood pressure monitor is a device that is used to calculate blood pressure and heart rate by measuring changes in artery motion. It is a cuff that is placed around the arm and is inflated to measure the pressure in the blood vessels. The cuff is then released and the pressure is recorded.

Using a bluetooth blood pressure cuff can send the data in real-time to the clinician for review. The American Heart Association research has shown that remote cardiac monitoring can greatly reduce patient blood pressure.

At-home blood pressure monitoring can assist with the management of many conditions and symptoms of hypertension and high blood pressure can be easily detected through regular data collection.

Day-to-day monitoring offers regular insight into the status of the heart as opposed to one point-in-time reading. Remote blood pressure monitoring allows practitioners to perform regular virtual treatment on high blood pressure/hypertension nursling.

Moreover, regular data collection can give more accurate information than one-time check-ups. And patients with hypertension or at risk of hypertension can keep tabs on their blood pressure and manage them over time.

ECG and Stethoscope

A stethoscope is a medical device that is used to listen to the heart and lungs. It is also used to measure heart rate and blood pressure. Electrocardiography (ECG or EKG) is a procedure used to measure the electrical activity of the heart. The test is usually performed while the person is resting.

The stethoscope captures heart and lung sounds while the ECG captures heart function. Smart detection systems like the Eko DUO can capture heart and lung sound virtually.

The digital stethoscope can self-monitor patients and send readings directly to a practitioner for clinical reviews which can enable early detection and more personalized care delivery. This can also reduce hospitalization or readmission following a hospital discharge.

A pulse oximeter is a medical device that measures light wavelength to determine oxygen levels in the blood. It is often used to check a person’s pulse, and blood pressure, diagnose heart problems, and monitor a patient’s response to treatment.

The pulse oximeter can be deployed to help healthcare providers monitor changes in any individual lung function. It can gather useful information from people with chronic heart or lung issues.


A glucometer is a device that is used to measure blood sugar levels. It is a handheld device that can be used to estimate blood sugar levels from the sample that is taken. The patient places a small drop of blood on a test strip that is connected to a device that produces the blood glucose reading.

The reading is then sent in real-time to a practitioner to evaluate and provide a review. For someone with type 1 and type 2 diabetes, using a glucometer daily is essential. It is often used multiple times a day to keep tabs on their blood sugar.

Collecting data from glucometer regularly allows practitioners to understand factors (such as stress, illness, diet, and exercise) affecting the person’s blood sugar and diabetes symptoms. Blood glucose level is the most common remote patient monitoring application.

Practioner can capture data from remote blood glucometers to detect changes in glucose levels and alert the patient when there is a potential risk. The data also provide insight to guide the practitioner’s recommendation for dieting, exercising, and medications.


A thermometer is a device used to measure temperature. A thermometer provides body temperature and essential information for the next steps of care. A bluetooth thermometer can provide a fast and accurate picture of patient conditions like fever.

Fever is a key indicator for many conditions and symptoms. Using thermometers in-home monitoring can track patient recovery as well as signal providers when there is a symptom.

Smart scales

Smart scale uses sensors to detect the weight of the person being weighed, and then send the information to a smartphone app. The app tracks changes in weight over time, and practitioners can monitor those changes to ensure everything is correct, and intervene if needed.

It is essential that a practitioner can observe weight changes since weight gain can be a key indicator of different symptoms. Patients with obesity can use scales to enable self-management and motivate themselves to take responsibility and identify trends.


A spirometer is a medical device used to measure respiratory rate and lung function. A spirometer is inserted into the airway to measure the amount of air that is inhaled and exhaled. The spirometer is worn on the chest and uses an algorithm to calculate the respiratory rate.

Remote spirometry can monitor a patient’s lung conditions and send the data to a practitioner for virtual assessment. This can be useful for helping the care receivers better manage breathing issues.

Medical alert system

A medical alert system is a service that provides patients with a way to be notified in case of an emergency. If the sufferer has an implantable medical device, such as a pacemaker, a medical alert system can notify if something goes wrong. These devices can provide immediate intervention by alerting the wearer’ doctor, the nearest medical facility, or a family member.

Medication monitoring

Medication monitoring is the practice of monitoring a patient’s medication levels to identify potential side effects and potential interactions. It also helps guide the dosage of medications to be given to a sufferer.

Connected pill dispensers are now available to monitor patient medication intake as well as an alert when it’s the right time for intake. Intelligent dispensers can connect patients and providers to allow real-time communication.
