A few squats to get her going... but you know what made her race more..?

Woke up a bit early yesterday so decided to do some squats with the 3 leads - I then this morning thought that editing before medicating was a brilliant idea.... if you want my heart pounding and anxiety going try editing like this...

Still a noob with the video editing so I think I still didn't perfectly line it up but we will get there. I was standing so not the cleanest lines around, but it was interesting to see the waves change with exercise.

What do you think? I personally think it's fascinating seeing the waves of electricity required to keep her pumping and keep me alive and how it just knows that is needed in the moment.

An overview of the Philips MP5 from the outside from an engineer’s perspective

I’ll explain everything in the most basic and interesting way as I can I’ll go over everything on all 4 sides of the monitor, if people like this then we’ll take a look at the insides of the monitor as well

Front View:

1: Mount release button. Pushing this button unlocks the internal mechanism that locks onto the quick release mount.

2: Speaker. I have tape over it to try to make it not as loud, I think it goes without saying that all the sound the monitor produces comes through here

3: Mains AC indicator light. Just an LED to tell you if the the monitor is plugged into mains power

4: Battery indicator light. Lights up green when the monitor is running on battery or when there is mains power and the battery is fully charged. Lights up red when the battery is charging

5: Power indictor light. Lights up when the monitor is turned on

6: Power button. White rubbery plastic button that turns the monitor on or off

7: Alarms Off/ Paused indicator light. A red led that lights up if alarms are paused or off to remind hospital personnel that they are off/ paused.

8: Alarm indictor LEDs. Flash red or yellow or stay solid red, yellow, or blue depending on the severity of the alarm. Blue is low priority things like no pulse oximeter connected, no ecg leads connected, low battery, or can’t analyze. Yellow is medium priority alarms, things like HR, SPO2, RR, Temp, BP going out of the set alarm minimum or maximum, minor arrhythmias (skipped beats, Afib, tachycardia, bradycardia, etc…) Red is high priority (the sound that turns on most people who are into resus) things like: SVT, Extreme tachycardia, extreme bradycardia, VFIB, V-Tach, Asystole

And then there’s obviously the large 8 inch touch screen LCD. This one is a resistive touch screen as opposed to the capacitive touch screens in most phones, tablets and other devices. There’s 2 reasons for using a resistive touch screen: 1 is that they are far more reliable and durable compared to capacitive touch screens, capacitive touch screens usually always use glass where as resistive screens use plastic. The second reason is that resistive touch screens can be pressed with anything so it makes it really easy to use with thick gloves, isolation suits, the back of pen, or anything else, as opposed to capacitive touch screens which require the thing pushing it to have natural capacitance like human flesh.

Right side view

1: IEC mains input. This is where the power goes into the monitor, I’ve read the whole service manual and it says that in order to comply with regulations you must use a hospital grade power cord. I was lucky the monitor came with a hospital rated power cable but to be honest it makes no difference what type of cable you use for home use the regulations are just there because they are required in hospitals. There isn’t much of a difference between hospital grade and regular service rated power cables. A hospital grade power cable is usually 16AWG-3 SJTW (16 American wire gauge, 3 conductors, Service Junior Thermoplastic Weather resistant insulation) whereas standard household rated IEC cables are 18AWG-3 SJT (18 American wire gauge, 3 conductors, Service Junior Thermoplastic insulation (not rated for wet locations)). This monitor has a universal switch mode power supply in it, which means it can take any voltage from 100 volts AC to 240 volts AC at 50 to 60 Hz frequency, which is the range of all electrical systems worldwide. I’m surprised it has a switch mode supply in it, they tend to be very noisy (produce a lot of electromagnetic interference that interferes with the sensitive components in the rest of the device) and they generally aren’t used because they don’t always provide full isolation from mains or they don’t provide as much isolation as a standard medical rated transformer-rectifier supply.

2: On board recorder. This is a 50mm monochrome thermal printer. It can print status reports, ECG recordings, and a few other things. I haven’t tested it because the paper is hard to find for a decent price.

3. Battery compartment. This compartment holds an M4605A Lithium-ion 10.8 volt battery. (That part number is probably a roll over from the HP Viridia line of patient monitors because Phillips bought the rights to all of HPs patents for the Viridia line so a lot of the stuff for intellivue and Viridia are backwards compatible. The only reason I say that is an HP part number is because they really liked to put an A at the end of almost every model number of something they made) The monitor didn’t come with a battery so I bought a used one for $20, a new one directly from Philips is $700. The 6th pic is the battery itself, it has a built in state of charge display. It’s a 65 watt hour (6000mAh) capacity battery using 18650 cells. The capacity of mine has dropped to 5700mAh. The monitor uses about 1.1 amps from the battery during normal operation so I can get about 5 and half hours of battery life.

Left side view

1: Output for Non invasive blood pressure (blood pressure cuff) pretty simple, but interestingly after reading the service manual, you can stick a hex key in the slot and actually replace just that connector

2: SPO2 input (pulse oximeter) input for a pulse oximeter, fast SPO2 is a trademark of Masimo referring to some kind of “special” technology they use. (I put that in quotes because I’m pretty sure it’s the same as all other pulse oximeters) you can get a few different types of pulse oximeters for Philips monitors. There’s 2 types of finger pulse oximeters, clip on, or adhesive/ Velcro (the Velcro and adhesive ones tend to be disposable and more often used for long term monitoring or for pediatric patients, they can also go on a toe) There are also ones that clip onto the lobe of the ear, but they aren’t used very much, probably due to not as good accuracy.

3: ECG input. This connector is the input for ECG electrodes. It’s a 12 pin connector (service manual actually gives a pinout) the reason it’s 12 pins is because this connector can support 3, 5, 6, 10, and 12 lead cables. This connector is used on all Philips monitors, and it’s actually backwards compatible with Hewlett-Packard/ Agilent technologies Viridia line of patient monitors (something of which my grandfather who recently passed away built prototype parts for when they were being developed) I think Philips bought the right to use all of HP’s patented connectors and hardware for patient monitors that also includes the classic alarm sounds I much prefer over the standard ISO alarm sounds. The modern intellivue line of Philips monitors evolved from the HP/ Agilent Viridia line of patient monitors.

Rear side view

This is where things get interesting because this is different on a lot of MP5 monitors, that’s due to this rear I/O being a card inside the monitor that can be swapped out. This card happens to be the full configuration card with every I/O option available for this monitor.

1. USB port. Used to connect a mouse and keyboard, or a barcode reader. The barcode reader can be used to quickly scan barcodes on medications so they can be input into the huge amount of info the monitor can collect. It can also be used to scan patient wrist bands or staff ID cards

2. Nurse call relay output. This is where things get a little more technical. This 3.5mm jack is connected to a relay that turns on every time an alarm goes off. What’s a relay? It’s basically a switch that can be turned on and off with an electromagnet, this allows me to wire up just about anything so that when an alarm goes off it turns on too. This was a really interesting part in the service manual because it said to change the relays configuration from normally open to normally closed you literally have to desolder a surface mount resistor from the PCB. I’ve never seen a service manual say to desolder something to change its configuration.

3. RJ45 LAN Ethernet Jack: this is used to connect the monitor to the hospitals network infrastructure including data storage servers, patient data servers, others monitors on the network, telemetry consoles, and much more. I’ve done a little playing around with this but unfortunately haven’t gotten very far because I’m currently taking care of my grandmother at her house and my servers that I have to mess around with things like this are at my house so I can’t play around with any of the software options currently.

4: Video Output: Just a standard VGA video output to connect it to a larger external monitor. My old monitor had this but it wasn’t setup on the stock configuration and I had to tap into it with a molex connector on the motherboard.

5: Ground connection for ECG: This is used for testing and calibration but if I had to guess it’s on the outside of the monitor and not hidden away inside for compliance reasons.

6: Mains earth connection. This is also here for testing purposes. The inside of the monitor has a metal frame that serves 2 purposes. 1 is added rigidity to help it stand up to being dropped and abused (which happens a lot in hospitals because things are so high stress all the time). And 2 is EMI shielding. EMI is electromagnetic interference, basically all the different frequencies of radio waves that are constantly surrounding us. The amplification circuitry responsible for amplifying the tiny electrical signals put out by the heart that are tiny fractions of a single volt is quite venerable to any interference because the electromagnetic waves can have higher power than the signal you’re trying to amplify thus making the signal appear noisy (when it looks like it has a bunch of fuzz or something instead of a thin line). To counter EMI we can use the idea of a faraday cage. A faraday cage is a simple concept, you surround whatever you are trying to protect from EMI in an electrically conducive material (usually some kind of metal) and you connect that thing to the ground (quite literally shoving a wire in the ground). This works because all electromagnetic waves want to find their way back to the earth somehow, so by putting our sensitive circuits inside a grounded metal box all the electromagnetic waves that hit the metal will immediately be absorbed and led to the earth where they want to go completely bypassing our sensitive circuitry. According to the electrical code of pretty much any country, any electric device with metal exposed to touch must have a connection to mains earth. That’s why most cords have 3 wires instead of just the 2 you normally need to complete a circuit. This connection to mains earth is because in almost all mains electrical systems the neutral wire (the wire that the electrons return to the source from) is the earth or is at least bonded to the earth. That means that if you touch a live wire and you are standing on the ground the electricity can travel through you and electrocute you. Sometimes you don’t even have to be touching the ground to still get a shock and that’s due to the natural capacitance your body has. You are capacitively coupled to the electrical grid at all times and that means you can draw tiny amounts of current from your body, not anywhere near enough to do any damage to your organs as it’s only a few micro amps, but this is the reason for an ECG signal appearing noisy if the filters aren’t set correctly. If the live wire connected to the device accidentally makes contact with the metal housing then there’s a possibility you could be electrocuted because you are touching ground or at least capacitively coupled to it. To counter this is that green ground/ protective earth wire that is connected to the devices metal housing will carry the current back to earth because it is much less resistive than you and electrons always take the path or least resistance. This will result in a short circuit and will trip a circuit breaker but it’s much better than being electrocuted.

That was a long one but I hope you learned something. I think I’ll do a walkthrough of the software side of things and a look at the parts inside. Throughout this whole thing I referenced the service manual several times. A service manual is a manual provided to a repair technician that explains how to, setup, test, calibrate, and take apart the device, and sometimes they go as deep as including the schematics of all the circuits in the device. These days they are pretty hard to get your hands on because companies don’t want you to fix your stuff and would rather you just buy a new one. However I found the service manual for the MP5 very easily with 1 Google search. It’s about 300 pages long and is filled with information about these monitors that not even most health care professionals know. It lists the passwords for all different operating modes in the software, how to connect the thing to a network, pinouts of all connectors, info on how to test it, a whole section dedicated to how to take the thing apart, a list of the part number of each component in case you need to order a new one, the layout of the channels for the short range radio module inside, and so much more.

What Do You Need to Know Before Trying an ECG at Home? 

The rise of home-based ECG devices has captured the public's interest in India. A recent study by the Indian Institute of Public Health suggests a surge in demand, particularly among those concerned about heart health. But for cardiologists and general physicians, questions remain.  

Can these devices offer reliable data when taking ECG at home? How can we integrate them effectively into patient care? Through the medium of this informative piece, we'll sneak peek into the latest research, explore the potential benefits and limitations of home ECGs, discussing how to best utilize them for optimal patient outcomes. 

Examining the ECG at Home Trend from a Doctor's Perspective 

The convenience and accessibility of devices to take ECG at home are undeniable. Patients with suspected heart conditions, particularly those in remote areas or facing mobility challenges, can now monitor their heart rhythm with greater ease. It empowers them to take a more active role in their health and potentially detect arrhythmias earlier. 

However, for doctors, integrating home ECG devices requires a critical assessment. Here are some key considerations: 

Accuracy and Interpretation 

While home devices have improved significantly, concerns remain regarding their accuracy compared to clinical-grade ECGs. A 2023 study published in the Journal of the American College of Cardiology found that single-lead devices might miss certain arrhythmias. 

Additionally, proper interpretation of ECG results requires expertise. False positives can lead to unnecessary anxiety for patients and increased workload for doctors. 

Optimizing Patient Care 

To leverage home ECGs effectively, clear communication with patients is crucial. Doctors need to educate patients on proper device use, potential limitations, and the importance of not relying solely on home ECGs for diagnosis. 

Establishing protocols for interpreting data and flagging abnormal results is essential. This might involve using telemedicine platforms for remote consultations or setting thresholds for triggering in-person follow-ups. 

Collaboration and Future Directions 

Devices that allow you to take an ECG at home are a valuable tool, but they shouldn't replace traditional consultations and diagnostic procedures. Collaboration between patients, doctors, and potentially, AI-powered analysis platforms can optimize their use. 

Further research is needed to explore the accuracy of multi-lead devices and the development of user-friendly interpretation tools for patients and doctors alike. 

Benefits Beyond Arrhythmia Detection 

While arrhythmia detection remains a primary focus, home ECGs offer broader potential. They can be used for: 

Monitoring the Effectiveness of Heart Medications. This allows for timely adjustments and potentially reduces the need for frequent clinic visits. 

Pre- and Post-Operative Cardiac Care. Home ECGs can provide valuable data for managing patients undergoing heart surgery or procedures. 

Screening High-risk Populations. Individuals with a family history of heart disease or those with pre-existing conditions like diabetes might benefit from regular home ECG monitoring. 

A Balanced Approach with SanketLife Portable ECG Device-

Devices to take ECG at home offer a promising avenue for empowering patients and enhancing cardiac care delivery. However, navigating the complexities of accuracy, interpretation, and integration into existing workflows remains crucial. 

The SanketLife portable wireless ECG device, developed by Agatsa, stands out for its innovative touch-based technology. This user-friendly approach simplifies data collection and eliminates the need for cumbersome electrode placement. Moreover, SanketLife's AI-powered analysis provides real-time insights and facilitates doctor consultations through the integrated app. 

While further research is necessary to solidify the role of home ECGs in clinical practice, devices like SanketLife demonstrate the potential to bridge the gap between patient convenience and physician oversight. As the technology matures and integrates seamlessly into healthcare ecosystems, home ECGs have the potential to revolutionize the way we monitor and manage heart health in India.
