The Important Use Of Pulse Oximetry

Pulse oximetry is a non-invasive method of monitoring individual's oxygenation. Whenever a person oxygenation level is unstable, oxygen level assessment is necessary. This kind of scenario is usually seen in intensive care units, emergency and wards areas of a medical facilities. Oximeter reading is usually intended to individuals having respiratory and cardiovascular diseases. Aside from its use in oxygenation monitoring, it could also possibly determine ventilation abnormalities. However, detection of hypoventilation is not likely.

Pulse oximeter is proven to be helpful in the medical field. However, the oximeter also has its limitations. Although it can measure the oxygenation level, sad to say it cannot determine oxygen metabolism. Oxygen metabolism is the amount of oxygen used up by an individual. Because of this, carbon dioxide monitoring is necessary. Oximeter could not be also a good substitute for checking of blood gases levels in laboratories since it gives no indication of base deficit, carbon dioxide levels, blood pH, and bicarbonate concentrations.

Oximeter readings may sometimes be inaccurate as it only reads the percentage of bound hemoglobin. It is important for you to know that hemoglobin could be bound to other gases as well such as carbon dioxide and monoxide. False low readings may occur when there is hypoperfusion of the extremity. This usually occurs when the port is cold or there is vasoconstriction. Erroneous readings can also result from incorrect application of the sensor, a thickly calloused skin and unnecessary movements. Therefore, it is important that the oximeter sensor must be in positioned properly to ensure accuracy. The patient must be warned to avoid any sudden movements. False high or low readings may also take place due to physiologic factors. It is when the hemoglobin binds to something other than oxygen which can eventually lead to cyanide and carbon monoxide poisoning. Cyanide poisoning can yields a false high reading because it reduces the oxygen extraction from the arterial blood.

Even though there are limitations and flaws in this device, it is still good to know how this simple tool brought a tremendous impact in our everyday lives. With its use, the standard of care of medical institutions worldwide is vastly improved since way back in the 90's and until in the present wherein modern technologies made the device more sophisticated, improved and refined. Oximeter is one of the medical devices that are essential to human life. Our world may have a hard time coping without it.

Solar power battery chargers

The history of solar power battery chargers has to begin with the advent of solar power. Attempts to capture the power of the sun have been made since the dawn of man. Realizing its power to give heat and light, intrigued man from the beginning of time. Leonardo da Vinci studied the sun and ways to harness it in the fifteenth century.

Although modern science has taken away the romance of sun gods, mystical beings and other myths and tales, it has not lost its curiosity. Harnessing the suns power to be used in batteries has been around since France decided it needed an alternate energy source long before the fuel shortage of the seventies.

Charles Fritz managed to turn the suns rays into electricity with the first solar cell in 1883. It wasn't until later in the 1880's that a solar cell was used to warm water in his house. The studies went on. The possibilities of using up all of the nonrenewable resources was well known in the nineteenth century. People around the world still chose to use coal and other nonrenewable energy sources as though they would never end, or have any consequences.

Three scientists from Bell Labs, Calvin Fuller, Daryl Chaplin and Gerald Pearson made the discovery that silicon was a very good semiconductor. Today solar cells and panels are usually made of silicon.

These small yet applaudable steps were baby steps to the many uses of solar energy today. Now, solar energy is influencing the production of energy much more than those in history ever imagined. It is no longer history, it is the future that depends on solar power and the ability to use the sun as an energy source and to not deplete the earth of nonrenewable resources.

Then the price of oil doubled in the seventies, the government of the United States finally decided to invest time and funds into the development of the solar cell. This is the same solar electric cell that was produced in 1953 by the scientists at Bell Laboratories.

Today the assortment of solar powered battery chargers is amazing. When you inventory your electronic gadgets, you know that everyone needs to be charged in one way or another. You will find out that most of those electric chargers can be replaced by solar battery chargers.

The solar charger contains solar panels. When these panels are placed in direct sunlight, the panels will convert the energy from the sun and store it in your battery. The more energy you want, the larger the solar panel you will need. Portable solar chargers are available and built into many small devices. Solar powered calculators have been around for decades. At first large and cumbersome, they are now pocket sized and more efficient.

Internal solar batteries are usually what you will find in these small hand held devices. Price counts. There are some that are too small to charge the device with just the sun, but can charge the internal battery. Internal batteries will most likely have to be replaced before the device wears out. Replacement of an internal battery will most likely occur every couple of years and is a danger to the ecosystem. A weak battery in a new device is also a potential issue.

External solar chargers are great when you aren't anywhere close to an electric outlet. You can plug the charger into your device on a beach, in a foreign country or out in a boat with no AC power. They are also great if you are camping. You can get solar panels large enough to keep everything in your camp charged and usable without tapping into electrical power supplies. They are great for any emergency, survival or your pleasure when electricity is not available.

Before you invest in a solar charger, it will be important to see if your appliances and devices can be used with one. The additional purchase of cables may be necessary in some instances.

In order to charge rechargeable batteries you will need a separate solar power charger. Since this will most likely be used outdoors, it is important to buy one that is weatherproof. Keep the connections clean and free from anything that may clog them and the panels themselves will function more efficiently if they are also kept clean and free from dust and grime.

Recent Articles On Single Black Parents

The number of single-parent families is increasing everywhere. The 2002 US Census found that three of every ten children were living in a single-parent home. Experts believe the number to be steadily increasing and expect the trend to continue for years to come.

Increasing acceptance of divorce as a solution to marital problems is one social factor supporting the increase in single-parent families. With that acceptance has come greater tolerance for parents without partners.

Single parents face many challenges. They must earn a living and raise their children without the help and support of another adult at home. They face financial difficulties if they don't receive child support or have a big salary. Their time is over-booked with work, household duties, parent-teacher conferences and PTA meetings, and attempts at private time for rest and relaxation.

Support systems for single parents are growing, but they still frequently feel isolated and alone. New single-parents must cope with children who are having their own problems adjusting to the new lifestyle. They may face anger, feelings of abandonment, and rebelliousness from children who feel they don't get enough attention.

Although there are no clear census data on the number of single black fathers, experts assume the number to be increasing as well. They express concern that single black fathers may face more pressure than other single parents due to continuing social discrimination, despite less political or legal discrimination.

Many experts assume that males are less equipped to be single parents than females, arguing that men don't receive the same level of training in domestic tasks and that women are naturally more nurturing care-givers. However, other professionals assert that men are more likely to be objective and logical in their decision-making for the household and that they are more consistent in disciplining their children that women are.

Interviews of African American full-time single fathers conduced by Robert Coles of Marquette University explored why they wanted to be full-time fathers. When the men talked about their motivations, they listed fulfilling their responsibilities, reworking their own feelings about their absent fathers, being a role model, and maintaining an established relationship with their children.

Several new studies have been conducted by experts and psychologists trying to learn more about black single-parenting. There are also a number of websites containing information and advice focusing on the black male's single-parenting experience.

The following articles are examples of the literature available on the Internet targeting black male single parents.

1. "Parent Trapped: Dating for Single Parents." Penned anonymously by a male single parent, this article talks about the author's experiences with dating as a single parent. Assuming his experiences can be generalized to other men and to black single fathers, readers can relate to his joys and challenges.

2. "The Bad Rap Against Mothers." This article was published in a popular main-stream magazine several years ago, but it remains fresh and relevant. Its author is a single mother who was abandoned by her black male partner.

3. "The Bad Rap Against Mothers, Part 2." A second part to the previous article, Part 2 more carefully describes and analyzes the challenges presented by single parenthood for mothers. The author imagines what life might have been if she had been the one to leave the relationship. Explaining her argument, the author believes that single parents are well-positioned to raise "exceptional men" who have good manners and lofty principles.

4. "Come Back Home" inspiring excerpt is from the popular "Chicken Soup for the Single Parent: Stories of Hope, Healing and Humor." This selection acknowledges that everyone's experience with single parenting is highly personal and that each single parent has their own story to tell.

5. "Get More Time with your Children and Manage Your Child Support" was written for black single-parent males, but it will be equally touching and valuable for white single fathers. The article gives insights into the personal and financial issues single-parent males face.

6. "Dreaming Through the Twilight" is as sweet and mushy as its title but at the same time profound. It is also available as a book that compiles personal diary-type articles on black single-parent males having difficulty coping with their life as single parents.
