Electrocardiographic Monitoring: What Is EKG Machine & How Does It Work

what is ekg machine

Many people experience irregular heartbeats from time to time, noticeable mainly during various activities, such as exercise, bowel movements, eating, sex, stress, and even sleeping. Thankfully, irregular heartbeats can be easily diagnosed and serious heart problems can be prevented by simply recording the electrical activity of the heart with the help of an electrocardiograph or EKG machine.

What is EKG machine?

Electrocardiograph, also called EKG, ECG, or simply cardiograph, is a medical instrument used for detecting and diagnosing common heart abnormalities by measuring heartbeat triggering electric potentials on the body surface and recording electrical currents associated with activity of a heart muscle. In other words, EKG machine is a galvanometric device that variations or contractions in the electrical conduction system of the heart, thus evaluating the heart’s health. The working principle of EKG is: to pick up the cardiac tissue-generated electrical impulses (polarization & depolarization), translate those impulses into a waveform (electrocardiogram), which is then used to measure the following:

The Importance of Kids’ Blood Pressure Control

High blood pressure or hypertension does not occur in adulthood only. More and more children are suffering from this disease. In many cases it is caused by obesity. It is vital to control child’s pressure because in future hypertension can even cause heart disease and stroke.

There are two methods of blood pressure measurement: invasive and non-invasive. The most accurate way is invasive. It is conducted by means of intra-arterial catheterization. However, you cannot do it at home yourself, so it is used under doctor’s supervision only. Non-invasive methods are more common because all you need is a blood pressure monitor.

Top Characteristics of Finger Blood Pressure Monitor

At present, millions of people are interested in their heart rate. The reasons for it are very diverse. Some people require this information because they go in for sports and it is vitally important to know heart rate before physical activities and after them. This information demonstrates how many physical activities people should do. For example, if the heart rate increases significantly as soon as the training is over, people should decrease the number of activities and increase them step by step. As a matter of fact, a high level of heart rate can cause a number of significant diseases, such as, for example, heart diseases, atrial fibrillation, heart rhythm disorders, cardiac arrhythmia, and others. Therefore, people should not exaggerate their abilities. Some people may have heart diseases and, as a result, they have to visit a doctor lots of times to keep fit and healthy. To avoid visiting doctors very often, people can use a finger blood pressure monitor and thus, they will be aware of their health conditions, which will let them take all the necessary medications on their own. This technological device has a number of benefits. The most common of them are the following ones: it saves a lot of time and thus, people can have a flexible time-table; people do not need to go to health care centers very often; people can regulate their activities appropriately; people can improve their healthcare outcomes on their own, and so on and so forth.

Vital Signs Monitor: Primary Characteristics

Nowadays, there are millions of people who have health problems. The reasons for it are very diverse: genetic problems; environmental situation and climate changes; injuries that can be caused by a car accident or other catastrophes; old age; chemicals that pollute the air and this list can be prolonged. More than that, we live in the technologically developed world, where each person is at a risk of getting injured. A risk to get injured is considered to be an inherent part of society. As soon as people feel pain, they turn for help to specialists to reduce the level of pain and come back to a normal style of life.

Physicians of the majority of well-developed healthcare centers prefer having a vital signs monitor due to its advantages: it simplifies the work process of physicians; it provides an opportunity to save a lot of time and, as a result, physicians can provide effective help to more clients; physicians can identify the place of pain and its cause; they can define the level of pain, which provides an opportunity to choose the required medications in an appropriate manner and provide effective help at once, and this list can be prolonged. Therefore, a lot of interesting questions arise: What is Welch Allyn vital signs monitor?, What advantages does it have?, Why should it be used in healthcare centers?

What Is Ambulatory Blood Pressure Monitoring: Reliable & Accurate Blood Pressure 24/7

ambulatory blood pressure monitor

Ambulatory blood pressure monitoring, or simply ABPM, is a relatively new and non-invasive method or technique of obtaining a patient’s blood pressure readings 24/7, while a patient stays in his/her own environment and represents a true blood pressure reflection. In the simplest terms, ABPM assesses or measures a patient’s blood pressure at regular intervals (every 20 minutes at daytime, every hour overnight). A device used for ABPM is called ambulatory blood pressure machine or monitor.

Many medical studies have already confirmed that 24/7 ambulatory blood pressure monitoring is superior to blood pressure monitoring in a clinical setting in estimating cardiac risk factors, like predicting future target organ damage and cardiovascular events. ABPM is able to provide the information that will be fundamentally different from the one got by a doctor out of a patient’s blood pressure readings taken in the office. For example, ambulatory blood pressure monitoring is believed to be helpful in reducing the effect of white coat hypertension, according to which a patient’s blood pressure gets elevated during a medical examination as a response to a simple anxiety or nervousness caused by being in a clinical environment. For this reason almost all hypertension organizations highly recommend to use ABP or out-of-office measurements as an adjunct to office measurements. Let’s take a deeper look at the main guidelines of ambulatory blood pressure monitoring technique.

The Primary Characteristics of Non Invasive Blood Pressure Monitor

non invasive blood pressure monitor

A non invasive blood pressure monitor is much used in medical practice. This device is used in healthcare and medical centers. Patients who have healthcare problems that are connected with blood pressure always use this device to measure their blood pressure. This device is not used under home conditions for a number of reasons: the prices for a device are rather high and not all people can afford buying this device; the instructions are rather complicated and, as a result, professionals study the instructions very carefully to use the device appropriately; the results that are shown by the device cannot be easily evaluated and interpreted by ordinary people.

Regardless of the fact that the device shows the results on the screen of the monitor, people should be aware of the minimum and maximum blood pressure rates to understand whether their results are within a norm or whether they are above or below a norm. More than that, as soon as people get the results, appropriate medical treatment should be applied. People are not recommended to choose medications on their own or on the request of their acquaintances, as these medications can cause severe complications. Only physicians who have examined patients have the right to prescribe appropriate medications. Physicians often use the device to get to know whether patients are ready for an operation. As a rule, people with too low blood pressure cannot be operated. Therefore, as soon as physicians get the results, they can take measures to prepare patients for an operation.

What Is a Sphygmomanometer: Definition & History of Invention

what is a sphygmomanometer

Sphygmomanometer, also called a blood pressure meter or sphygmometer, is an instrument or device that is specifically designed to measure arterial blood pressure. It is composed of an inflatable air-bladder rubber cuff that is wrapped around an upper arm and restricts any blood flow, and a mercury or pressure gauge (mechanical manometer) that actually measures the pressure. It’s a very simple but rather effective medical instrument with the help of which one can accurately measure one’s blood pressure, which, in fact, should be around 120/80 (normal blood pressure reading for adults).

Blood pressure sphygmomanometer (from the Greek ‘sphygmos’ – the pulse or beating of the heart, plus manometer – a tension or pressure measuring device) was firstly introduced in 1881 by Samuel Karl Ritter von Basch, and in 1896 an Italian physician Scipione Riva-Rocci invented a more easily-used version of this device, which in 1901 was modernized and popularized within the medical community by Harvey Cushing. At present, it is one of the most common medical instruments.

Finger Pulse Oximeter

A finger pulse oximeter is a device that measures oxygen saturation. A blood-oxygen monitor shows the percentage of blood that is loaded together with oxygen. To be more specific, the device measures the percentage of protein in blood that can be carried by oxygen only or the percentage of hemoglobin. A norm for people who have no pulmonary or lung diseases is 95 – 99 percent. As a matter of fact, there are a number of symptoms that indicate that people have a low level of hemoglobin.

The most common of them are the following ones: people fill dizzy; they have constant headaches and no antispasmodic medications are effective; people can lose coordination; they can lack air, and this list can be prolonged. As soon as people notice some of the aforementioned symptoms, they should turn for help to specialists, who will examine them and give all the necessary medications. At first sight, the symptoms that are connected with a low level of hemoglobin seem to be insignificant. However, that is not so. If no medical treatment is provided and patients’ outcomes do not improve, the healthcare outcomes may worse, which can cause severe complications or even lead to the death.

What Is a Pulse Oximeter? Common Types and Reasons of Regular Use

what is a pulse oximeter

What is a pulse oximeter? This is a non-invasive device that is commonly used both by specialists and non-professionals for measuring the blood-oxygen saturation level as well as pulse rate in patients. Oximeters and their sensors ensure the proven accuracy of results in a pretty wide range of patients, regardless of sex and age. However, these aren’t the only reasons why the devices are so popular. To additional benefits also belong:

  • compact size
  • non-invasiveness
  • the ability to detect hypoxemia earlier than when using eyes to see cyanosis
  • affordability

A comparatively small probe is attached to a computerized unit. It is clipped to the spot on one’s body that is characterized by a good blood flow (usually the earlobe or finger). There is a light emitter insides the probe. It sends out two streams of light – infrared and red. Opposite this emitter there’s a photodetector that receives the streams and measures them as they pass through.
