Article: You could either do this first, or wait until you've gathered some information on your own. Whichever option you choose, make sure to consult your doctor at some point in this process before making a final purchase. He can suggest which oximeter will work best for you and decide if you require any special features. While consulting with your doctor, decide what your goals are for using a pulse oximeter. There are several varieties of oximeter, so your intended use for it will help you pick one. If you only want to check your oxygen levels periodically, a small clip-on oximeter will probably work fine. If you have a chronic illness that requires continuous monitoring, you'll need a model capable of constant use. If the doctor also wants to measure your heart rate, he may want you to get an oximeter with a heart rate monitor. By talking with your doctor, you can narrow down your specific needs and make finding the right oximeter much easier. All pulse oximeters perform the same basic function: measuring the level of oxygen saturation in the blood. There are various types, however, all of which have specific advantages and drawbacks.   Portable or finger oximeter. This version is most commonly used at home. It is small, rectangular shaped and clipped on the finger. The display screen is on the probe itself. This type is usually battery operated. It is commonly used to spot check oxygen saturation by clinicians, caregivers, or patients themselves.  Handheld oximeter. This is mostly used by medical institutes and hospitals since it is slightly more sophisticated and gives more accurate readings. The probe is attached to a cable connected to the screen. In order to get a reading, the probe must be attached to the person’s finger — ideally the index finger. This type of oximeter is utilized for spot checks, but is also capable of continues oxygen saturation monitoring. It is usually utilized by hospitals, ambulatory health settings, home, or EMS.  Tabletops with sensors. This model is usually bigger than a handheld pulse oximeter. It is capable of spot checks and continuous monitoring. Its size makes it ideal for hospitals, medical facilities, home care and subacute settings.  Wrist-worn sensors. This model is wireless, and usually used for continuous monitoring. Your doctor may want to monitor your oxygen levels on a daily basis or while you sleep, making this model ideal. This instrument is designed like a wristwatch. A small wire connects the probe, placed on the index finger, to a small monitor on the wrist. The readings will appear on this wrist monitor.  Fetal pulse oximeters. If you need  to asses the oxygen saturation for children, you need to look for a brand that specifically indicated for children. Children’s pulse oximeters are  designed to fit snugly on small  fingers. There are also varieties that can attach to the foot or head that may work better if your child's fingers are very small. Besides different types, oximeters can include a variety of different features. Keep all of this in mind while gathering information to decide which are necessary for you.  Levels of accuracy. Some devices feature warning light, which would indicate whether there is interference or inaccurate reading. This will help you determine if your oxygen levels are low or if your device is malfunctioning. Alarms. Certain pulse oximeters would give out audible sound to alert users of low oxygen saturation. This is helpful for those who do not have a medical background and are not familiar with the normal range of oxygen saturation and heart rate. Readability of displayed measurements. Screen color and size can make a difference in reading the displayed data. Pick a display that you can read with no trouble. Durability and battery life. You intended use will help determine how durable of a machine you'll want. If it's just for personal use, you don't need an especially rugged machine. If you need only intermittent  oxygen readings, your device doesn't need a long battery life.For continuous oxygen saturation reading, you'll need either a very long battery life or a plug-in-device. This would prevent you from having to replace batteries often. Most probes come in the 0.3 inch to 1 inch size range, which can accommodate most adult fingers. You'll only need to seek another option if your fingers are either very large or very small. The probe should fit snugly around your finger. If your finger bulges out or protrudes in any way, the probe is too small. Consult a store employee for a larger size. If ordering online, measure your finger from the top of the nail to the bottom of the pad on the tip of your finger. Use this measurement to search for your specific finger measurement. After purchasing the oximeter, you should test it with your doctor. If it proves to be inaccurate, you'll want to be able to return it and get a more accurate one. When you decide on an oximeter, you'll need to check it for accuracy. Tests indicate that various defects can make oximeters vary widely in accuracy. To check yours, take it to your doctor's office. Compare the readings from his pulse oximeter to yours. If they are the same, your oximeter is in good working order. If not, return it and get another one.
Question: What is a summary of what this article is about?
Consult your doctor before making a purchase. Investigate different types of oximeters. Learn different features pulse oximeters offer. Check the sizing of the probe on your oximeter. Buy a pulse oximeter with a good return policy. Test the pulse oximeter with your doctor.
Article: Most sports analysts start off as sports fans. Once you’ve decided to pursue a career as a sportscaster, absorb as much knowledge about sports as you can. Keep up with collegiate as well as professional teams, and follow multiple sports rather than just one or two. A good sports analyst is expected to be like a walking encyclopedia of sports information. It is not enough to know all about one team, or even one sport. Sports analysts have to possess a thorough knowledge of all the most sports, including football, basketball, baseball, soccer, hockey, golf, boxing and even Olympic and extreme sports. Start paying close attention to game outcomes, player stats, win-loss records and other statistical information. Commit as much of these facts as you can to memory. Statistics is the language of sports analysis. As an analyst, your job will be to make authoritative assessments and predictions based on statistical models. There is far more use of mathematical principles in sports analysis than most people realize. Taking a formal statistics course or two will help further your understanding of how these principles come into play. Go to school and work towards a degree in journalism, communications or broadcasting. While it’s not strictly necessary to have one of these degrees in order to land a job in sports journalism, most employers prefer that applicants hold a bachelor’s degree or higher. Online programs are also available for those who are unable to attend university classes.  Holding a degree, along with the right experience, can give you an advantage over those without an education when it comes to getting hired. Many online programs can be completed in less time than a full term at a university, and include all the most relevant courses, such as news reporting, media ethics, sports psychology and broadcasting. Once you’ve earned an undergraduate degree, think about channeling your efforts into a post-graduate master’s or doctorate level certification. Many graduate programs include courses that focus more specifically on sports analytics and broadcasting, meaning you’ll be getting an education in your chosen field of expertise. These credentials will be very impressive to potential employers. A graduate degree will require you to significantly narrow your area of focus, which may not help you get your first job but can make you a commodity for special positions later on.
Question: What is a summary of what this article is about?
Learn as much as you can about sports. Become well-versed in statistics. Earn an undergraduate degree in a related field. Consider going for a graduate degree.
