Normal Breathing Rate

Breathing is essential for life as it involves taking in oxygen into the body and expelling carbon dioxide from the body. It supplies our body with the oxygen we need to get energy from food during respiration. Carbon dioxide is the waste product of respiration. It is toxic, and breathing helps remove it from the body.

What is breathing?

Breathing is a physical process that involves inhalation, relaxation, and exhalation. It has two stages: gas exchange and ventilation. Ventilation is the movement of air in and out of the lungs, while gas exchange takes place in the air sacs or alveoli in the lungs. Two things happen during the gas exchange; carbon dioxide diffuses into the lungs from the bloodstream, while oxygen goes into the bloodstream.

Breathing rate

Breathing rate refers to how often you inhale and exhale per minute. The breathing rate of a healthy person is as follows:

Six weeks and below: 24 to 40 breathes per minute Six weeks to 2 years: 25 to 40 breathes per minute3 to 5 years: 20 to 30 breathes per minute6 to 9 years: 18 to 25 breathes per minute10 to 64 years: 12 to 18 breathes per minute65 to 79 years: 12 to 28 breathes per minute80 years and above: 10 to 30 breathes per minute

The concentration of oxygen and carbon dioxide in the blood

Chemoreceptors help detect the concentration of different substances in the blood. In the case of a high concentration of carbon dioxide and a low concentration of oxygen, the chemoreceptors in blood vessels signal the respiratory center in the brain, triggering an increase in breathing rate. Your breathing rate increases when you’re exercising because your body needs more oxygen to burn calories. In the process of burning calories to get energy, the concentration of carbon dioxide rises, resulting in an increased breathing rate. Emotional factors, such as happiness and sadness can also affect your breathing rate.

A change in breathing rate when you’re relaxed is a sign of an underlying health condition, such as a heart attack. The heart rate and breathing are connected. Your heart rate and breathing rate increase when you are exercising due to oxygen deficiency and an increased amount of carbon dioxide.

Monitoring your breathing rate using a breath rate monitor helps you predict some health conditions that are about to occur. An increase in breathing rate can be a sign of a heart attack. In case your breath rate per minute is below or above the average, you should consult your doctor as soon as possible.

There are many ways to monitor the breathing rate. Technology has made it possible for people to monitor their breathing rate at home. You don’t have to go to the nearby clinic or hospital each and every time you want to know your breathing rate. Equivital has a breath rate monitor that is easy to use at home. The device is not only easy to use but also reliable as it is accurate.

What is the difference between etching and engraving

An engraved souvenir is a beautiful gift for anyone. There is a wide variety of items which can be purchased and engraved with the words you want, which will remain embedded in the mind of the recipient forever. Some of these come in the form of watches, pens, photographs, jewellery and other small treasures that will bring happy memories every time seen. Engraved gifts can be given for special occasions such as graduations, anniversaries, weddings, baptisms or even a special birthday. Etching, on the other hand, is a form of an engraving made on hard surfaces, such as metals which use chemicals in the process.

Some of the most engraved gifts presented by people are:

Photo frame: it is the most used gift object. People collect photographs and give them away, but if you give it a personal touch when registering the purpose or good appointments, it will add value to that photograph. For example, if you give a picture on a birthday, you can record the date of birth, the name and a sweet message on it. This will make it more special than a pure gift.

Gravure gift items are available in a variety of specifications, sizes, quality, colours, etc. on the websites. Internet is the most convenient way to buy personalized, engraved gifts.

Through the Internet, you will find hundreds of personalized gift items for use. Different gifts such as engraved shelves, bottle openers, keys, pens, medals, jewels, laser photographs, plates, pieces of paper, books and the list will last, there is no end. You can record almost all the gift items available in the store. There are engraved soaps available, engraved beans, candlesticks, etc. With just the fingertips, you can order to record any item, at a very nominal cost.

Gift engraving has also taken an individualistic approach. There are gifts available for him and her, as well as for a baby. You have to look at these gifts and buy them online, ask them to print the same.

Photochemical etching

Photochemical etching or Photochemical machining is ideal manufacturing to process precise fabric components. Chemical etching is achieved with a photoresist template as a method of elimination in selected areas. The first photoresist was developed in the eighties. However, the photochemical machine industry did not take off until the middle nineties.

The photochemical machining process begins with the manufacture of a photographic tool. There are several methods to produce photographic tools. The most common way is to create a photographic tool of the appropriate size and precision by using a laser photo machine to selectively display a photographic film based on data from computer projects.

The next step is to select and prepare the metal for photochemical engraving. The challenge with which a hard surface can be etched will mostly depend on the chemical content of the material since the process is a controlled chemical process. Before it can be laminated with the photoresist, the surface is cleaned with electrolytic alkali to remove dirt, rust, grease and oils. This pretreatment ensures excellent adhesion to the photoresist. Surface cleaning with electrolytic alkali is fast and reliable.

Introduction to the process of Chemical Etching

Chemical etching is a subtractive process of manufacturing metal parts in which baths of etching chemicals under controlled temperature conditions are used for producing metal parts of any shape with high precision. It is a more design flexible, cost-effective, and faster technique of manufacturing micro metal parts as compared to EDM Stamping, Laser cutting, Water jetting and CNC. Most of the manufacturers of industrial products or prototypes are using this method for manufacturing metal parts more accurately.

Working of etching chemical in the process of chemical etching

The process of chemical etching can be completed in various steps like cleaning, laminating, exposing, developing, etching and stripping. After all these steps all the components are rigorously checked to ensure their quality and precision.

A layer of light-sensitive material is first laminated on the sheet of the substrate, the material to be etched. This layer is exposed selectively to UV rays to get an image of the product you want to make. The patterned substrate is then exposed to etching chemicals to get the metal part as the chemical removes its unexposed parts. In order to produce high precision metal parts, every step is performed under strictly controlled conditions.

Benefits of etching chemical

Etching chemicals can help in producing high precision multi-layered and complex metal parts by using the process of chemical etching. The process of chemical etching can be used suitably for creating sharp edges, round holes, and profiled or straight edges while creating metal parts.

The etching chemical used in chemical etching makes this process the most affordable alternative for any manufacturing process from prototype to commercial production as compared to the traditional process of machining like electro-discharge machining, N machining, pressing, stamping, laser cutting, and wire erosion, etc. Chemical etching can help in producing a prototype from your drawings rapidly within a few days due to the flexible scalability and tooling of this process.

Materials that can be etched with etching chemicals

Etching chemical can etch a wide range of materials including various types of stainless steels, carbon steel, mild steel, spring steel, tool steel, molybdenum, aluminum of different grades, various alloys of nickel, oxygenated and oxygen-free copper, phosphor bronze, brass, nickel silver and beryllium copper along with a number of other materials.

Monitoring CBRN Workers for Heat Stress

CBRN workers are at particular risk for heat stress. CBRN, which stands for chemical, biological, radiological and nuclear, requires that everyone who works in it wear heavy protective gear. Quite often this clothing is not breathable and as result bodies get overheated leading to heat stress. Heat stress, when it is mild, can be easily treated and an employee can get back to work relatively quickly, but if it is extreme it can lead to coma and even death. This exposes you to massive lawsuits that could have easily been avoided if you dealt with the problem of heat stress effectively in the first place.
The first step is to let your employees know that heat stress is a real danger and they can easily find themselves in danger. They should all be familiar with the signs of an overheating body and they should know what to do when it happens. It is important that they understand that sometimes one may not know they are in trouble so they should watch out for each other.
Your employees should understand the importance of proper clothing in the workplace. The gear that they work in is going to overheat sooner or later but if they have the right clothing beneath it can go a long way in lowering their body temperatures. Do some research into some of the best fabrics for people who wear heavy gear and let your employees know so that they can invest in the right kind of clothing. Make sure that they know the value of hydration and frequent breaks while on the work floor.
Additionally you can invest in heat stress monitoring equipment. At a glance you will be able to see every employee’s vitals and you can step in whenever intervention is needed.
