In this blog, we will explore the opportunities and challenges that arise from the intersection of biomedical engineering and AI.

Opportunities

Medical Imaging: One of the most significant areas where AI is being applied in biomedical engineering is medical imaging. AI algorithms can be trained to analyze medical images such as X-rays, CT scans, and MRIs to identify abnormalities and provide a diagnosis. This can help radiologists to make more accurate and timely diagnoses, and can even help detect diseases before symptoms arise.

Drug Discovery: The drug discovery process is complex and time-consuming, but AI can help accelerate it. AI can be used to predict the interactions between drugs and specific biological targets, and to identify potential new drug candidates. This can help speed up the development of new drugs and make them more effective.

Personalized Medicine: AI can also be used to develop personalized treatment plans for patients. By analyzing a patient's genetic makeup, medical history, and other data, AI algorithms can identify the best treatment options for that particular patient. This can help improve patient outcomes and reduce healthcare costs.

Wearable Technology: The use of wearable technology such as fitness trackers and smartwatches is becoming increasingly common. AI can be used to analyze the data collected by these devices to identify patterns and trends that can help diagnose and prevent diseases.

Challenges

Data Quality: One of the biggest challenges in using AI in biomedical engineering is ensuring the quality of the data being analyzed. AI algorithms are only as good as the data they are trained on, so it is essential to ensure that the data is accurate, reliable, and representative.

Ethics and Privacy: The use of AI in healthcare raises ethical and privacy concerns. For example, who owns the data collected by wearable devices? How is that data being used? What happens if that data is used to deny someone healthcare coverage?

Regulation: As with any new technology, there is a need for regulation to ensure that it is used safely and effectively. In the case of AI in biomedical engineering, this means developing standards for data quality, privacy, and safety.

Bias: AI algorithms can be biased, just like human beings. This can lead to disparities in healthcare outcomes for different populations. It is essential to ensure that AI algorithms are developed and trained in an unbiased manner to ensure that they do not perpetuate existing inequalities.

Conclusion

The intersection of biomedical engineering and artificial intelligence offers exciting opportunities for improving healthcare outcomes. AI has the potential to revolutionize medical imaging, drug discovery, personalized medicine, and wearable technology. However, there are also significant challenges to overcome, including data quality, ethics and privacy, regulation, and bias. By addressing these challenges, we can ensure that AI is used to its fullest potential in improving healthcare for everyone. 

THERMOMETER

THERMOMETER

The thermometer is used as an “instrument for measuring temperature.” “Thermo” is a prefix related to heat, and “meter” is a suffix used for any measuring device.

What is a normal body temperature?

The normal body temperature is about 98.6 degrees in Fahrenheit (° F) or 37 degrees in Celsius (° C). Normal body temperature is usually lower in the morning and higher during the day. It reaches its peak in the late afternoon or in the evening.

Primary and secondary thermometers

Depending on how the measured gross physical quantity is assigned to the temperature, the thermometer is called primary or secondary. “For the primary thermometers, the measurement properties of the matter are well known, so that the temperature can be calculated without unknowns. For example, the thermometer based on the equation of state of a gas, the speed of sound in a gas , thermodynamics, noise voltage or current of a resistance, and the angular anisotropy of gamma rays emitted by certain radionuclides in a magnetic field .

Secondary thermometers are the most widely used due to their convenience. Furthermore, they are generally much more sensitive than primary thermometers. For  secondary thermometer, knowledge of a measurement properties is not sufficient to directly calculate the temperature. They should be calibrated to at least one set temperature or multiple temperatures using a primary thermometer. Such fixed points, such as the triple point and superconducting transition, can occur repeatedly at the same temperature.

Traditional thermometer

Traditional thermometers are non-register thermometers. In other words, after the thermometer is moved to a different temperature, the temperature reading is not maintained. Determining the temperature of a pot of hot liquid requires the user to leave the thermometer in the hot liquid until after the reading. If an unregistered thermometer is pulled out of the hot liquid, the temperature indicated on the thermometer will immediately begin to change to reflect its new condition temperature (in this case, air temperature). The recording thermometer is designed to hold the temperature indefinitely so  the thermometer can be removed and read later or in a more convenient location. The mechanical recording thermometer maintains the highest or lowest recorded temperature until it is manually reset, for example by shaking the mercury glass thermometer, or until a more extreme temperature is experienced. Generally the electronic recording thermometer can be designed to recall the highest or lowest temperature, or to recall any temperature that has occurred at a specific point in time.

Thermometers are increasingly using electronic means to provide digital displays or inputs to computers.

What Are the Different Types of Thermometers?

Not every thermometer is made in the same way,  the following types are the different types of thermometer:

• Digital
• Mercury/Alcohol
• Liquid Crystal
•  Meat/Food Thermometer

Digital thermometer

Digital thermometers are the most common type of thermometer and are  considered the safest. It is either a traditional stick or contains a probe at the end that can be scanned on the forehead. Either way, the temperature will be displayed on an easy-to-read display.

A simple digital thermometer is a combination of a thermocouple, a battery-powered dual-slope digital voltmeter (used to measure the output of the thermocouple), and an electronic display. It provides a low-noise digital output that can resolve temperature differences as small as 0.1°C. The accuracy achieved depends on the accuracy of the thermocouple element, but the measurement error can be reduced to ± 0 5%.

features of digital thermometers:

• Digital thermometers rely on metal and electrical probes to function.
• Since the numbers are displayed on the screen, you can easily read the temperature. The
• Digital Thermometer provides faster results than mercury thermometers.
• Recommends that you use a digital thermometer to measure the temperature of children or babies, because they are safer to use.

Mercury/Alcohol Thermometer

The first mercury thermometer was invented in 1714. Basically mercury is a dense and toxic metal, so that the Environmental Protection Agency (EPA) recommends that you handle these thermometers with care.

In a mercury thermometer, the glass tube is filled with the mercury, and the tube is marked with a standard temperature scale. As the temperature changes, the mercury expands and contracts, and the temperature can be read on the scale. Mercury thermometers can be used to determine body temperature, liquid and vapour temperature. Mercury thermometers are used in households, laboratory experiments, and the industrial applications.

features of mercury thermometers:

• Mercury thermometers are based on the natural chemical reaction between mercury and hot or cold temperature.
• You can read the temperature by checking where the bar falls on the line. The largest line is 1 ° F and the smallest line is 0.2 ° F.
• The  Mercury Thermometer can withstand boiling and freezing temperatures, while the Digital Thermometer can be damaged in extreme conditions.
•  It is dangerous if the mercury thermometer breaks on the ground, because mercury is poisonous.

Liquid Crystal thermometer

Liquid crystal thermometer is a tool for measuring temperature range and heat transfer mode. The result is shown by the color change of the cholesteric liquid material made into the liquid crystal thermometer. These thermometers are used in a variety of applications, from reading patient temperature to accurately measuring air and liquid temperature ranges in chemical laboratories or breweries. The low cost of this instrument, coupled with its ability to accurately measure a wide range of temperatures, makes this thermometer an indispensable part of many medical and manufacturing processes.

As the room temperature rises and falls, the color of the cholesterol-based liquid in the entire strip changes. To read the LCD thermometer, the user only needs to pay attention to the color change of the thermometer. In some cases, the thermometer is also marked with temperature and digital names to improve the accuracy of the readings.

Liquid crystal thermometers are generally used as equipment for home brewing of alcoholic beverages or other chemical reactions that require temperature adjustment. One of the most common types of thermometers in use today is duct tape, which adheres to the outside surface of a bottle or laboratory equipment and produces accurate readings of the temperature of the container. For micro-brewing and other operations, the thermometer can accurately measure the temperature range in the brewing vessel. Although the measurement is not as accurate as laser thermometers or traditional liquid-immersed thermometers, the results produced by liquid crystal thermometers are accurate enough for reactions that must be kept within a certain temperature range, rather than a specific target temperature.

In a laboratory setting, liquid crystal thermometers can be used to measure temperature changes and transmission modes. The cholesterol-based liquid in the thermometer can be used to effectively track heat transfer through convection, radiation, and conduction. By heating the thermometer and then tracking the rate of evaporation or immersion of the liquid to reduce the temperature of the thermometer, the same principle can also be used to test the cooling characteristics of the liquid.

Meat/Food Thermometer

You can buy a special thermometer for cooking! The food thermometer is inserted directly into the meat to ensure that the internal temperature is fully cooked.

Cooking food to the required internal temperature ensures that you will not eat dangerous bacteria. When you want to know whether the required internal temperature has been reached, you need a food thermometer.

According to the U.S. Food and Drug Administration (FDA), the following should be the minimum internal temperature for meat:

Beef: 140°F

Pork: 145°F

Poultry: 165°F

Fish: 145°F

What Are the Different Ways a Thermometer Can Be Used?

The thermometer is designed to measure body temperature in many different ways. In fact, some thermometers are designed for certain parts of the body.

• Axillary thermometer (under the arm)
•  Oral thermometer (under the tongue)
• Tympanic thermometer (in the ear)
• Rectal thermometer (in the rectum)
• Infrared or temporal artery thermometer (above the forehead)

Axillary Thermometer

For this method, a thermometer is placed in the armpit for use by young children or adults who cannot safely measure body temperature through their mouth. This method is not as accurate as the oral or rectal method, but can be used as a quick first check.

Oral Thermometer

For this method, the thermometer is placed under the tongue. This method is suitable for adults and children 4 years and older who can hold a thermometer in their mouth.

Tympanic Thermometer

This type of thermometer measures the temperature in the ear by reading the infrared heat in the ear. For best results, be sure to follow the device’s instructions for proper tip placement. For babies and older children, ear thermometers can be used faster and easier. However, if your baby is less than three months old, they are not recommended. If your child has excess earwax or earaches, they should not be used.

Rectal Thermometer

It can be difficult to take the temperature of younger children since they don’t sit still, so that rectal thermometer is a good solution and is often recommended for infants.

Temporal Artery Thermometer

In recent years, infrared or temporal artery thermometers have become very popular. This type of thermometer is very comfortable to use and one of the most comfortable options.

 Forehead thermometers are also used to measure temperature, but they may not be as reliable as digital thermometers and are usually more expensive. They are placed in the temporal artery of the forehead and measure the infrared heat emitted from the head.

Which Type of Thermometer is Most Accurate?

Using an oral thermometer will give you the most accurate results. Make sure to place the thermometer under your tongue and keep your mouth tightly closed.

If you are using a digital thermometer, it is also important to keep the thermometer in place for at least 30 seconds. You should avoid eating or drinking for at least 20 minutes before taking your temperature for best results.

Can I Use a Food Thermometer to Check My Body Temperature?

If things get complicated, you can use a meat thermometer to measure your body temperature. It is definitely not as accurate as a medical or clinical thermometer, but it will work when necessary. The  Coronavirus (COVID19) pandemic has caused a severe shortage of digital and mercury thermometers in stores across the country. Meat thermometers became a good substitute during the crisis. If you use this method, be sure to place the thermometer under your tongue and keep it still. If you have a high fever, contact your doctor as soon as possible.

Can a Smartphone Be Used as a Thermometer?

Do you need to take your temperature? There is an app! You will find options to track fever on Android and iPhone.

The following apps will measure your body temperature and can be used on Android and iPhone:

 Fingerprint Thermometer

•  iThermonitor
• Real Thermometer
• Smart Thermometer
• Vick’s SmartTemp
• Thermometer ++
• EasyBBQ
•  iCelsius

This is not an exhaustive list, but these apps are the most popular. They work through a digital scanner, which reads your temperature when you place your index finger on the screen.

 Please note that these applications may not be as accurate as glass or electronic scanners, so proceed at your own discretion. When in doubt, it is best to use a doctor-approved thermometer to measure your body temperature.

 If  Your Mercury Thermometer Breaks then what do you do?

If your mercury thermometer  gets break, don’t panic. The Environmental Protection Agency (EPA) has created these easy-to-follow tips to make you safe:

• Immediately  Get your kids and pets out of the room
• You should open up the window and leave it open for at least 15 minutes
• You must wear rubber gloves and old clothes to clean up the mercury beads and glass.
• You should Collect the mercury beads with an eyedropper. Note: You should not use a broom or vacuum.
• You can use torch lights to make sure that you have found all the beads.
• If you still see small beads, put shaving cream on top of a paintbrush and then you can “dot” the affected area. You can then use the duct tape to grab those tiny beads.
• You should Wipe the affected area with a damp cloth, making sure to get every inch
• You should Put the  beads, your gloves, the duct tape, the eyedropper, and the cloth inside of a garbage bag. Tie the bag carefully and securely closed.
• Then you can Contact your local health or fire department to find out how to properly dispose of the bag.
• Make sure to Let the room ventilate for the next 24 hours

 Do Thermometers Expire?

The thermometer will not expire, but will eventually need to be replaced. Digital thermometers will last 3-5 years, while mercury thermometers will be used indefinitely as long as they are not broken or damaged.

Has your mercury thermometer stopped working? Put it in the fridge or freezer. The cold will cause the mercury to vibrate a bit, which may fix the problem. If not, it may be time to look for alternatives.

Can You Recycle a Thermometer?

Thermometers are considered hazardous waste and which are cannot be recycled. Your best option is to wait for your community to host a hazardous waste collection day or find a facility near you. If possible, please avoid throwing hazardous waste into the trash can. This includes not only thermometers, but also for the lighters, pesticides, paint, batteries, and electronic products such as mobile phones and TVs.

Conclusion

The thermometer is a great invention! You can easily check for a fever, and you can do this in a number of ways. Your health should always be the number one priority, so make sure you always have a working thermometer in your home.

   

VIDEO LARYNGOSCOPE

 

VIDEO LARYNGOSCOPE

What does Larynx do?

The larynx is a hollow tube that connects the rest of the respiratory system to the throat (pharynx).

It is also called as voice box since it helps in swallowing and protects the vocal cords. The major

role of larynx is assisting you in speaking, breathing, and swallowing. Larynx is located at the rear

of your throat and the top of your trachea, or windpipe. It is home to your vocal cords, which

vibrate to produce sounds when you talk.

Overview of laryngoscope:

Laryngoscope is an endoscope of the larynx. A laryngoscope is a small hand instrument that

doctors use to see into your larynx and other neighboring regions of your throat, or to introduce a

tube into your windpipe to help you breathe. A small video camera is frequently included in

modern versions of the laryngoscope gadget.

• Indications for laryngoscopy

15. Suspension of carcinoma

Therapeutic:

1. Intubation

2. Foreign body removal

3. Biopsy

4. Micro-laryngeal surgery

5. Placing gastric tube, Transesophageal echocardic probe

Video Laryngoscope:

Video laryngoscopy is a type of indirect laryngoscopy in which the doctor does not look at the

larynx directly. Instead, a fiberoptic or digital laryngoscope (a camera with a light source) is

inserted trans nasally (through the nose) or trans orally (through the mouth) to see the larynx

(through the mouth).

During video laryngoscopy, images and recordings taken during the process can be seen on a

monitor by physicians, patients, and others. It can also be recorded and watched at a later date. The

photos and video can also be used to track the evolution of the disease and its treatment. When the

pictures are presented on the monitor, they are enlarged, which aids in a thorough study of the

larynx. Fiberoptic intubation is based on video laryngoscopy.

Technique

Video laryngoscopy is a relatively recent technology that was developed to improve tracheal

intubation success rates. A high-resolution micro camera fitted on the tip of a curved blade and

coupled to a small portable digital monitor improves the view of the vocal cords and, as a result,

the direct laryngoscopy success rate. The larynx is visualized from outside the mouth orifice during

direct laryngoscopy. The distance between the laryngoscopist's eye and the vocal cords is

considerable (30–40 cm). With a traditional laryngoscope, this decreases the angle of view to about

15°. Direct viewing of the airway might be difficult or impossible due to improper alignment of

the oral, pharyngeal, and laryngeal axes, as well as a variety of anatomic or pathologic reasons.

Since the digital camera, video laryngoscopy has substantially increased the angle of vision.

Because the digital camera and light source are put so close to the larynx (2–3 cm), video

laryngoscopy considerably increases the angle of vision.

Video laryngoscopy in the pre-hospital setting

Due to severe facial trauma, neck or cervical spine injuries, or oropharyngeal edema attributable

to angioedema or anaphylaxis, emergency care providers may be faced with a quickly deteriorating

airway status. Pre-hospital patients typically have simultaneous head injuries, multi-system

trauma, or suspected cervical spine injuries, and EMS providers are frequently involved in

maintaining the most challenging airways.

As a result, the safest and most efficient approach with the lowest morbidity rate should be used

to secure a definitive airway. As a result, VL could be an excellent option for safer laryngoscopy

and intubation.

Advantages of using video laryngoscope

• Because the eye and airway do not have to be aligned up as in direct laryngoscopy,

laryngeal visibility is improved.

• When compared to direct laryngoscopy, less force is used.

• Less cervical spine movement.

• Short learning curve.

• Laryngoscopy and intubation may cause less hemodynamic stress.

• Useful teaching tools.

• When compared to flexible fiber optic laryngoscopes, portability and cost are improved.

• Higher success rate in general, especially in tough conditions.
