In modern healthcare, electrocardiogram (ECG) monitors have become essential devices in hospitals, clinics, ambulances, and home care. They can continuously monitor patients’ ECG, heart rate, blood pressure, oxygen saturation, and other vital signs, alerting medical staff to abnormalities and providing accurate data for diagnosis, ensuring patient safety.
This article will introduce you to the main series of electrocardiogram (ECG) monitors, well-known brands, their battery types, and usage precautions.
1. Main Series of ECG Monitors
ECG monitors are generally categorized into three main types based on usage scenarios, functions, and portability:
ICU/Critical Care ECG Monitors
These monitors are most commonly used in intensive care units (ICU). They offer comprehensive monitoring, including ECG, blood pressure, oxygen saturation, respiratory rate, and temperature. High-end models also feature multi-lead ECG monitoring and real-time data transmission, allowing doctors to perform remote monitoring.
Typical models include:
Philips IntelliVue MX Series
GE Healthcare CARESCAPE Monitor Series
Mindray BeneVision N Series
These monitors are typically larger and require a fixed power source, but they come with rechargeable batteries to ensure short-term continuous monitoring during power interruptions or transport.
General Ward/Operating Room ECG Monitors
These monitors are used in general wards, operating rooms, and post-operative recovery units. They provide essential monitoring of ECG, heart rate, and oxygen levels. Compared with ICU monitors, they are smaller, easier to operate, and more convenient for bedside use.
Typical models include:
Nihon Kohden Life Scope G9
Mindray iMEC Series
Schiller ARGUS Series
Most of these monitors feature built-in or removable lithium batteries for short-term mobility and operating room transitions.
Portable/Home ECG Monitors
With the growing demand for home health monitoring, portable ECG monitors have become popular. These devices are compact, rechargeable via USB or dedicated chargers, and some models support Bluetooth or Wi-Fi connectivity to smartphone apps for remote monitoring.
Typical models include:
Omron HeartGuide
AliveCor KardiaMobile
Withings Move ECG
These devices typically use lithium-ion rechargeable batteries, with battery life ranging from several days to weeks, suitable for daily heart rate and rhythm monitoring.
2. Popular Brands and Market Overview
Globally, ECG monitor brands are diverse, with major players from Europe, the US, and Asia:
-
Philips: Known for the IntelliVue series, ideal for ICU and operating rooms, with reliable performance and long-lasting batteries.
-
GE Healthcare: CARESCAPE series is widely used in critical care, equipped with replaceable lithium batteries for continuous monitoring.
-
Mindray: A leading Chinese brand, BeneVision and iMEC series offer cost-effective solutions for hospitals and community healthcare centers.
-
Nihon Kohden: Specialized in ECG monitors, the Life Scope series supports multi-parameter monitoring with stable batteries for ward mobility.
-
Schiller: ARGUS series is compact, suitable for operating rooms and outpatient monitoring, with removable batteries for easy replacement and charging.
These brands share common features: high reliability, accurate data, and high-performance lithium batteries that ensure short-term monitoring even during power interruptions.
3. Battery Types for ECG Monitors
The type and capacity of batteries directly affect mobility and continuous monitoring. Common types include:
Rechargeable Lithium-Ion Batteries (Li-ion)
Advantages: compact, high energy density, no memory effect, long lifespan
Typical capacity: 2000–6000mAh
Usage: portable monitors, ward mobility
Nickel-Metal Hydride Batteries (NiMH)
Advantages: affordable, environmentally friendly
Disadvantages: lower energy density, shorter runtime
Usage: some older monitor models
Lead-Acid Backup Batteries
Advantages: stable and cost-effective
Disadvantages: bulky and heavy
Usage: large ICU monitors as backup power
Hospitals usually keep 2–3 spare batteries for each monitor to ensure uninterrupted operation during power outages or patient transport. Battery maintenance and charging follow strict protocols to extend lifespan and ensure safety.
4. Battery Maintenance and Usage Tips
To ensure the stable operation of ECG monitors, battery care is essential:
1. Regularly check battery health: Monitors often display battery capacity; replace aging batteries to prevent sudden power loss.
2. Avoid overcharging or deep discharge: Lithium batteries should not be consistently used at low levels or overcharged to extend lifespan.
3. Storage environment: Keep batteries in a dry, temperature-controlled area to prevent heat or moisture damage.
