# When doing 2 rescuers CPR what is the compression to breath ratio for children?

When two rescuers are preforming CPR on a child, the compression to breath ratio is 15:2. That is 15 compressions 1-1.5" deep at a rate of 100 compressions a min. Each rescue …breath should last about one second and make the chest clearly rise. The cycle is then repeated, fifteen compressions and two breaths. The rescuers should change positions about every 2min or about 10 cycles. (MORE)

# How To Calculate Cholesterol Ratios

In addition to tracking Total cholesterol, LDL (bad) cholesterol, and HDL (good) cholesterol, there are several cholesterol ratios that can help assess heart disease risk. Bey…ond the total numbers, it's a good idea to know your cholesterol ratios, as these can be strong predictors of coronary heart disease.There are two ratios that may help identify heart disease risk: the ratio of Total Cholesterol to HDL Cholesterol, and the LDL-to-HDL Cholesterol ratio. That these two ratios can predict heart disease risk was shown in the Framingham Heart study. As reported in Discovery Fit & Health, "In the Framingham Heart study, for instance, the ratio of total cholesterol to HDL and the ratio of LDL to HDL were found to have the strongest associations with coronary heart disease. The researchers suggested that a total-cholesterol-to-HDL ratio greater than six and an LDL-to-HDL ratio greater than four indicated a high risk for coronary heart disease."Although the American Heart Association recommends using the absolute numbers for Total and HDL cholesterol, they also note the usefulness of the Total Cholesterol to HDL Cholesterol ratio. "The ratio is obtained by dividing the HDL cholesterol level into the total cholesterol. For example, if a person has a total cholesterol of 200 mg/dL and an HDL cholesterol level of 50 mg/dL, the ratio would be 4:1. The goal is to keep the ratio below 5:1; the optimum ratio is 3.5:1." Said more simply, start with the Total Cholesterol number and divide by HDL. A good result is 5 or less, and 3.5 is optimal. If the result is 6 or greater, you should discuss with your doctor.The HDL/LDL ratio can be confusing because there are two different measures. Some divide HDL into LDL, and others divide LDL into HDL. For the ratio that starts with the HDL and divides that by the (usually larger) LDL figure, the goal is greater than 0.3, and ideal is over 0.4. This is the HDL/LDL ratio. As this can be confusing, eMedTV provides a good example: "...if a person has an HDL cholesterol of 50 mg/dL and an LDL cholesterol of 150 mg/dL, the HDL/LDL ratio would be 0.33. The goal is to keep the ratio above 0.3, with the ideal HDL/LDL ratio being above 0.4."Sometimes, the relationship of HDL and LDL is expressed in the opposite way: starting with the (usually larger) LDL figure and dividing that by HDL. The conclusion drawn in the published article, The LDL to HDL Cholesterol Ratio as a Valuable Tool to Evaluate Coronary Heart Disease Risk, is that until the tests (like apoliprotein B testing) than some consider to be better predictors of heart disease risk than current Total, HDL and LDL are more widely available, using the LDL/HDL ratio rather than just the actual numbers can be a strong predictor of heart disease risk.As stated above, this was borne out in the Framingham Report, where the goal for the LDL/HDL ratio is a score lower than 4. That said, this journal article reports a slightly more stringent goal: "The current NCEP guidelines recommend levels of LDL and HDL that represent a ratio of about 2.5. Current research suggests risk of death from cardiovascular disease begins to increase significantly around a ratio of 3.3-3.7." Net, if your ratio is between 3 and 4, you should discuss with your doctor.Some doctors might simply provide you with cholesterol ratio results. Be sure to ask for the actual numbers: Total Cholesterol, LDL and HDL Cholesterol and Triglycerides so you have the actuals and can calculate the ratios.Knowing all the elements of your lipid panel is important; make sure your doctor provides you with a printout of your Total Cholesterol, HDL, LDL and Triglycerides. Often the Total Cholesterol to HDL Cholesterol and the LDL-to-HDL Cholesterol ratios are included on the bloodwork report. If they're not, you can use the information provided here to calculate your own ratios to discuss with your doctor. (MORE)

# The Replacement Ratio Method of Determining Retirement Income Need

One of the key components to retirement planning is figuring out how much income you'll need during retirement. Besides helping you to determine the size of the nest egg that …can support your desired lifestyle, it will also make it possible for you to determine precisely how much you need to save on a monthly basis to make that a possibility.In general, the replacement ratio method of figuring out your retirement income need expresses the amount of income that you would need to maintain your pre-retirement standard of living during your retirement years as a percentage of your current earnings. So for example, if you currently make $60,000 a year, and believe that you would need only about $45,000 a year in retirement; your replacement income ratio would be 75 percent.One of the mistakes that many folks make is assuming that there is some form of a magic replacement income ratio that applies to everyone across the board. In reality, however, there is no such thing in retirement planning. Your replacement ratio will be directly related to how your personal expenditures are expected to change when you retire, compared to your years before retirement. While there are certainly some general rules of thumb, you should resist the temptation of basing your retirement income solely on a generic number.The most common oversight you are likely to make when figuring out your retirement replacement income ratio is by thinking that all of your expenditures will decrease during retirement, and by default, therefore, your ratio should be lower. Certainly some expenses like retirement account contributions, work-related uniforms, and commuting to and from work will fall off the expense sheet. However, certain expenses that are unique to retirement, including, health-care and pursuing certain hobbies may take over. The issue comes in when you fail to properly reflect the impact that any new items of expenditures will have on your overall outlay. That is why it is strongly recommend that you talk to a competent financial advisor who can help guide you through the process of properly assessing your situation.Because the underlying premise of the replacement ratio approach to forecasting your retirement income need is the assumption that your standard of living during retirement will be the same as your pre-retirement years, it will not work for those who intend on exceeding their pre-retirement standards during retirement. Also, if you expect certain drastic changes in your lifestyle during retirement that may cause you to have increased expenditures, this may not be the best way to determining your income need.Given that there are so many variables involved in retirement income planning, you should make it a point to review your replacement ratio number from time to time, especially as you get closer to retirement.One of the most significant injustices you can do to your future retirement comfort is by planning around income generalities. When it comes to this area of retirement, keep in mind that your specific set of circumstances, alone, should dictate what will be best for you. (MORE)
