What are vital signs?
Vital signs are measurements of the body's most basic functions. The top four vital signs routinely monitored by healthcare professionals and healthcare professionals include the following:
- body temperature
- respiratory rate (respiratory rate)
- Blood pressure (Blood pressure is not considered a vital sign, but is usually measured with vital signs).
Vital signs are useful for detecting or monitoring medical problems. Vital signs can be measured in a medical setting, at home, at a medical emergency facility, or elsewhere.
What is body temperature?
A person's normal body temperature varies based on gender, recent activity, food and fluid intake, time of day, and, in women, the stage of the menstrual cycle. Normal body temperature for a healthy adult can range from 97.8 degrees F (or Fahrenheit, equivalent to 36.5 degrees C or Celsius) to 99 degrees F (37.2 degrees C). A person's body temperature can be measured in one of the following ways:
- Oral.Temperature can be taken orally using the classic glass thermometer or the more modern digital thermometers that use an electronic probe to measure body temperature.
- Rectal.Temperatures taken rectally (with a glass or digital thermometer) are typically 0.5 to 0.7 degrees Fahrenheit higher than when taken orally.
- armpit.Temperature can be measured with a glass or digital thermometer under the arm. Temperatures measured this way are typically 0.3 to 0.4 degrees Fahrenheit lower than temperatures measured orally.
- With the ear.A special thermometer can quickly measure the temperature of the eardrum, which reflects the body's core temperature (the temperature of the internal organs).
- through the skin.A special thermometer can quickly measure the temperature of the skin on the forehead.
Body temperature may be abnormal due to fever (high temperature) or hypothermia (low temperature). According to the American Academy of Family Physicians, a fever is indicated when the body temperature rises about one degree or more above the normal temperature of 98.6 degrees Fahrenheit. Hypothermia is defined as a drop in body temperature below 95 degrees Fahrenheit.
About glass thermometers containing mercury
According to the Environmental Protection Agency, mercury is a toxic substance that poses a risk to human health and the environment. Due to the risk of breakage, glass thermometers containing mercury must be disposed of and disposed of properly in accordance with local, state, and federal laws. Contact your local health department, waste disposal authority, or fire department for information on proper disposal of mercury thermometers.
What is the pulse rate?
Pulse rate is a measure of heart rate, or the number of heartbeats per minute. When the heart pushes blood through the arteries, the arteries expand and contract with the blood flow. Pulse measurement not only measures heart rate, but can also display the following:
- heart rhythm
- wrist strength
The normal heart rate for healthy adults is between 60 and 100 beats per minute. Heart rate can fluctuate and increase with exercise, illness, injury, and emotions. Women over the age of 12 generally have a faster heart rate than men. Athletes such as runners who do a lot of cardiovascular training can have heart rates close to 40 bpm and not have any problems.
How to check your pulse
As the heart forces blood through the arteries, you feel the beats pressing hard on the arteries, which are close to the surface of the skin in certain parts of the body. The pulse is on the side of the neck, on the inside of the elbow, or on the wrist. For most people, the easiest way is to measure the pulse on the wrist. When using the lower neck, be careful not to press too hard and never press the wrists on both sides of the lower neck at the same time to avoid blocking blood flow to the brain. When measuring heart rate:
- Use the first and second fingertips to press firmly but gently against the arteries until you feel a pulse.
- Start counting your heart rate when the second hand on the watch points to 12.
- Count your heart rate for 60 seconds (or for 15 seconds and then multiply by four to calculate beats per minute).
- When counting, do not constantly look at the clock, but focus on the pulse beat.
- If you are not sure of your results, ask someone else to tell you.
If your doctor has told you to check your own pulse and you are having trouble finding it, contact your doctor or nurse for further instructions.
What is the respiratory rate?
Respiratory rate is the number of breaths a person takes per minute. Rate is usually measured when a person is at rest and simply involves counting the number of breaths taken per minute, counting the number of times the chest rises. Respiratory rate may increase with fever, illness, and other medical conditions. When checking for breathing, it is important to also note whether a person is having trouble breathing.
Normal breathing rates for an adult at rest range from 12 to 16 breaths per minute.
What is blood pressure?
Blood pressure, measured by a nurse or other health care professional using a blood pressure cuff and stethoscope, is the force of blood against the artery walls. Each time the heart beats, it pumps blood into the arteries, resulting in the highest blood pressure when the heart is contracting. You can only measure your own blood pressure when using an electronic blood pressure monitor. Electronic blood pressure monitors can also measure heart rate or pulse.
When measuring blood pressure, two numbers are recorded. The top number, or systolic pressure, refers to the pressure in the artery when the heart contracts and pumps blood throughout the body. The lower number, or diastolic pressure, refers to the pressure in the artery when the heart is at rest and filling with blood. Systolic and diastolic pressures are recorded in "mm Hg" (millimeters of mercury). This record represents the height of the mercury column in an old-fashioned manual sphygmomanometer (called a mercury manometer) raised by blood pressure. Today, your doctor's office tends to use a simple scale for this measurement.
High blood pressure, or high blood pressure, directly increases the risk of coronary artery disease (heart attack) and stroke (stroke). With high blood pressure, the arteries can have a greater resistance to blood flow, causing the heart to pump harder to get the blood circulating.
According to the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, high blood pressure in adults is defined as:
- 140 mm Hg or higher systolic pressureor
- 90 mm Hg or higher diastolic pressure
In a 2003 update of the NHLBI guidelines for hypertension, a new blood pressure category called prehypertension was added:
- 120 mm Hg - 139 mm Hg systolic pressureor
- 80 mm Hg - 89 mm Hg diastolic pressure
NHLBI guidelines now define normal blood pressure as follows:
- Systolic pressure less than 120 mm Hge
- Diastolic pressure less than 80 mm Hg
These numbers are to be used as a guide only. A single high blood pressure reading is not necessarily indicative of a problem. Your doctor will want to see several blood pressure readings over several days or weeks before diagnosing hypertension (high blood pressure) and starting treatment. A person who normally has lower than normal blood pressure may be considered hypertensive with blood pressure readings less than 140/90.
Why should I monitor my blood pressure at home?
For people with high blood pressure, home monitoring allows your doctor to monitor how much your blood pressure is changing throughout the day and from day to day. This can also help your doctor determine how effective your blood pressure medication is.
What special equipment is needed to measure blood pressure?
Blood pressure can be measured using an aneroid monitor, which has a dial indicator and is read by looking at a pointer, or a digital monitor, where the blood pressure reading flashes on a small screen.
About the aneroid monitor
Aneroid monitor is cheaper than digital monitor. The cuff is manually inflated by squeezing a rubber bulb. Some devices even have a special feature that makes it easier to apply the cuff with one hand. However, the device can easily be damaged and become less accurate. As the person using it must listen to the heartbeat with the stethoscope, it may not be suitable for the hearing impaired.
About digital monitor
The digital monitor is automatic, with measurements appearing on a small screen. As the records are easy to read, this is the most popular blood pressure monitor. It is also easier to use than the aneroid, and since there is no need to listen to the heartbeat through the stethoscope, it is a good device for the hearing impaired. One downside is that body movement or an irregular heart rate can change the accuracy. These units are also more expensive than aneroid monitors.
About finger and wrist blood pressure monitors
Tests have shown that finger and/or wrist blood pressure monitors do not measure blood pressure as accurately as other types of monitors. Also, they are more expensive than other monitors.
Before measuring your blood pressure:
- Rest without speaking for three to five minutes before taking a measurement.
- Sit in a comfortable chair with your back supported and your legs and ankles uncrossed.
- Sit still and place your arm on a table or hard surface at heart level.
- Wrap the cuff gently and snugly around your upper arm. The cuff should be sized to fit comfortably, but still leave enough room for the fingertip to slip underneath.
- Make sure the lower edge of the cuff is at least 2.5 cm above the crease of the elbow.
It is also important that when measuring blood pressure, you record the date and time of the measurement, as well as the systolic and diastolic measurements. This is important information for your doctor. Ask your doctor or other healthcare professional to teach you how to use the blood pressure monitor correctly. Check the meter's accuracy routinely by taking it to your doctor. It's also important to make sure the hose isn't twisted when you store it and keep it away from heat to prevent cracking and leaking.
Proper use of blood pressure monitor will help you and your doctor to monitor your blood pressure.
