    Buy pulse oximeter should be considered

    A pulse oximeter is a medical device specifically designed to measure the level of oxygen of the blood. It is a very simple device and saves you a lot of time in going to doctor to have this procedure done. What the pulse oximeter basically does is connect to one end of the finger and the hemoglobin saturation is measured and is compared to normal levels (which are usually between 95 to 100% saturation). When looking at pulse oximeters for sale, there are a few factors to consider.

    You should know that there are many types of oximeters and that you should select the one that is appropriate for you and fits your needs. These oximeters range from small to large, but the larger ones are used mainly in hospitals. The smaller, handheld oximeters and the portable fingertip pulse oximeters are ideal for use at home and even for sport and fitness applications.

    Oximeters also differ in prices and when looking at pulse oximeters for sale, you should determine how much you are willing to spend. Luckily, there are oximeters to fit just about anyone’s budget (not to mention the fact that there’s a good chance that your health insurance plan will cover the purchase). The price range for these oximeters vary across the board in terms of less than a hundred dollars up to a couple thousand dollars. You must keep in mind that the higher priced oximeters do not necessarily mean better quality. However, what you should be looking for is an oximeter which gives an accurate, saturation readings and pulse rates.

    Another factor to note is that if you are going to be using the pulse oximeter on your own and in the privacy of your home, you will need to make sure that the device is quite simple for you to use and understand. You should also ask for a demonstration from the seller of the device to clarify any questions which may arise when you reach home and are trying to use the pulse oximeter. If this isn’t available, some online sellers provide sufficient information through tutorials and videos.

    When you purchase your oximeter, be sure to find out the terms and conditions of returning and refund in the event of you not being satisfied with the product. Most manufacturers will be more than happy to exchange the oximeter you bought with one that better fits your requirements and personal likes.

    Based on the previous point, if you choose to purchase your pulse oximeter online, you should make sure that you do the necessary research. A trustworthy website will include testimonials from customers expressing their real views on using the oximeters. Some sites also offer discounts and better warranties than others. Be sure to buy from a company that has reliable customer service for helping you get started with your oximeter.

    When looking at available oximeters for sale, it’s highly recommended to use the internet to research the different types of finger oximeters. In a few minutes, you can find out the exact specifications and prices in just about every model on the market.

    What’s Kinds Of People Should Having An ECG Machine

    An ECG machine, also known as an Electrocardiogram machine, is a diagnostic device used in patients with heart-related problems. Physicians usually order this test for patients who report anxiety, dizziness, weakness, difficulty in breathing, chest pain and shortness of breath, to name just a few.

    What Can an ECG Machine Do?

    This machine works by recording the electrical impulses emitted by the heart. This non-invasive diagnostic procedure can detect the following:

    ¡¤ Heartbeat rate and regularity

    ¡¤ Positioning and size of the cardiac chambers

    ¡¤ Diseased or damaged tissue, as well as structural abnormalities

    ¡¤ Pacemakers and surgical repairs, as well as the effects of certain drugs on the heart

    One thing that this machine cannot measure is blood flow.

    Parts of an ECG Machine

    This machine is comprised of different structures. The biggest part is the circuitry box which houses the machine. It is linked to a number of electrodes, depending on the type of machine. These electrodes detect impulses, which are then recorded in pairs. Each pair is called a lead.

    How To Read The Regular Heart Wave Patterns Of ECG Monitor Testing

    When you are in charge of purchases for a large medical center, a clinic, or a hospital, you may feel an overwhelm with the price range of the available electrocardiography, ECG simulators, and the ECG simulation features.

    On one hand you feel that simulation is essential in keeping patient monitors in great working shape since the livelihoods of many of your patients depend on them. On the other hand, you dislike the complexity of the multitude of the features that some simulators provide and you are not sure that you really need them all.

    Testing patient monitors on actual patients, even though it might technically be the best possible solution, is quite impractical – who has the nerve to test the equipment in a potentially life threatening situation!

    In this article we will go over three standard ECG simulator features that no hospital ECG simulator can do without. When your chosen human patient simulators contain these features, you can rest assured that the ECG analysis part of your patient monitor checks will go well and will produce meaningful results, providing ongoing safety of your patients.

    The three must-have standard ECG simulator features are Regular heart wave simulation, Arrhythmic heart wave patterns, Electric noise patterns.

    Regular heart wave patterns

    A variety of regular heart wave patterns is included with each ECG simulator. It provides a baseline for the testing procedure. While synthetic or real patient heart waves will do in this situation, a mix of both is preferred, for a more realistic assessment.

    Synthesized or real patient arrhythmic heart wave patterns

    Depending on where in the heart muscle the problems arise, there are several dozens of different types of particular arrhythmias of the heart that can be present in the ECG printout. The heart is basically divided into left and right side, and into the atrium portion (top, smaller), and ventricular portion (bottom, larger). Electrically, the origin of the electric impulses is at the top of the heart, in the atrium walls, and the signal then travels through the walls of atrium, through the AV region (atrium-ventricular region) where it gets appropriately delayed, and finally reaches the ventricular walls.

    Abnormal heart patterns are named by the region in which the anomaly originates, and whether it represents faster than normal or slower than normal motion. Every ECG simulator will therefore produce patterns such as ventricular tachycardia, or speedup of ventricular chamber beats, bradycardia or slowing down, missed beat, asystole or no heart beat, SVT, or supra ventricular tachycardia, or faster than normal beating of the heart above the ventricule, and so on. Altogether, there will be three dozens or more of such test patterns included with every ECG simulator machine.

    Electric noise patterns

    In real life there is always electric noise present everywhere around us. One such important noise component is the 60 Hz noise that is present in the electric wiring of the buildings in the USA, and 50 Hz noise in Europe. Such noise, as well as other noises, perhaps microwave level noise from the cell phones and wireless networks can be incorporated reasonably into the signal of a basic ECG simulator.

    There Are Four Main Types Of Pulse Oximeter

    Pulse oximeter is a device that are used to measure amount of oxygen in the blood. It consists of a monitor in which oxygen levels is seen in percentage values. Red blood cells absorb the light which is measured by the other side of the probe. An average amount of several pulses must be detected in order for the oximeter to work. Low blood and a weak pulse leave the pulse oximeter to detect inaccurate results.

    There are four main types of pulse oximeter: bedside, wrist, hand held and finger type. Each type has several of models to choose from. A bedside oximeter is typically used in stationary medical facility and suited for non ambulatory patients such as those who are chronically ill. Wrist oximeter is those usually used by individuals involved in sports activities and is used for sleep monitoring.

    The handheld type can be seen in hospital. It is commonly used in doctor’s offices and emergency medical services because of its portability and affordability as compared to bedside units. It is similar to the fingertip device but it has a more versatile clip with a cord connecting to a computer. It is clipped onto a patient’s fingertip or earlobe and it uses light to measure blood’s hemoglobin. It is usually used in the cases where patient’s extremities are compromised and blood flow is impeded. In cases of extreme emergency, health professionals clip handheld oximeter at the patient’s toe.

    Fingertip oximeter is the most known and is widely used in medical institutions and even at homes. It is appealing to individuals since it is easy to operate, affordable and handy. It is clipped on the patient’s fingertips in which a light is emitted and measured from one side and another. The computer measures the light over several pulses and renders a value reading of the blood-oxygen level. However, pulse oximeter may not give an accurate reading if there is blood flow occlusion due to injury.

    There are still other kinds of oximeter. One type is the fetal pulse oximeter which is used to assess the oxygen level of a fetus and can also measure the baby’s heart beat. Probes are inserted into the birth canal and placed on the baby’s skull. The sensor shoots light across the probe and measures the hemoglobin level on the scalp.

    You can choose among these types of oximeter best suited to you. However, medical consultation with your health provider is essential to attain a correct interpretation of the results.

    Some Questions About Fingertip Pulse Oximeter

    Fingertip Pulse Oximeter

    What is a fingertip pulse oximeter?

    What does a pulse oximeter measure?
    What does oxygen saturation level means?
    Reasons for measuring oxygen saturation level.
    Types of oximeter readings.

    What is a fingertip pulse oximeter?

    It is a device used for measuring blood oxygen saturation using electrical sensors placed on a fingertip.

    How does a fingertip pulse oximeter work?

    An oximeter uses two light-emitting diodes generating red and infrared lights to a translucent part of body like fingertip. Tissues and blood vessels within the fingertip normally absorb a constant amount of light over time. The ratio of light absorbed as the heart contracts and relaxes and blood volume increases and decreases is translated into an oxygen saturation measurement.

    What does a pulse oximeter measure?

    Pulse oximeter measures the oxygen saturation of haemoglobin in arterial blood described as SpO2. Most oximeters also display pulse rate and a pulse waveform/bar graph depicting the strength of the pulse

    What does oxygen saturation level means?

    Red blood cells contain haemoglobin. One molecule of haemoglobin can carry up to four molecules of oxygen after which it is described as “saturated” with oxygen. If all the binding sites on the haemoglobin molecule are carrying oxygen, the haemoglobin is said to have a saturation of 100%.

    Most of the haemoglobin in blood combines with oxygen as it passes through the lungs. A healthy individual with normal lungs breathing air will have an arterial oxygen saturation of 95% – 100%.

    Reasons for measuring oxygen saturation level.

    Human life can not be sustained without oxygen. All body organs require oxygen for metabolism but the brain and heart are particularly very sensitive to lack of oxygen and a serious shortage of oxygen ( Hypoxia) for a few minutes can be fatal.

    In a clinical setting pulse oximetry may be performed to assess the adequacy of oxygen levels (or oxygen saturation) in the blood in a variety of circumstances such as heart attack, congestive heart failure, chronic obstructive pulmonary disease (COPD), anaemia, lung cancer, asthma, pneumonia, cystic fibrosis,emphysema, cystic fibrosis, occupational lung diseases like asbestosis, silicosis, farmer’s lung, There may be other reasons for your doctor to recommend pulse oximetry

    Types of oximeter readings.

    Spot-check

    These compact finger tip devices can be used to obtain a single reading quickly usually in about 30 seconds and is easy to carry and increasing number of health care professionals carry this in their coat pocket.

    Continuous readings

    Some wrist worn type of oximeters with small finger tip probes allow for continuous reading and commonly used by athletes, joggers, in adventure sports, during mountain climbing and also in health care settings like sleep studies.

    Continuous Remote Monitoring

    Some oximeters commonly used in hospitals can be used for remote monitoring where readings can be transmitted through cable or bluetooth wireless connectivity to a remote display unit where readings for several patients are monitored in a central unit.
