Pulse oximetry
Pulse oximetry is a noninvasive method for monitoring a person’s oxygen saturation (SO2). Though its reading of peripheral oxygen saturation (SpO2) is not always identical to the more desirable reading of arterial oxygen saturation (SaO2) from arterial blood gas analysis, the two are correl...Read more -
What is ECG/EKG?
ECG, also referred to as EKG, is the abbreviation of the word electrocardiogram – a heart test that tracks the electrical activity of your heart and records it on a moving paper or shows it as a moving line on a screen. An ECG scan is used to analyze the heart’s rhythm and detect irregularities a...Read more -
The Benefits of Physical Activity
Regular physical activity is one of the most important things you can do for your health. If you’re not sure about becoming active or boosting your level of physical activity because you’re afraid of getting hurt, the good news is that moderate-intensity aerobic activity, like brisk walking, is...Read more -
Blood pressure chart
Blood pressure readings have two numbers, for example 140/90mmHg. The top number is your systolic blood pressure. (The highest pressure when your heart beats and pushes the blood round your body.) The bottom one is your diastolic blood pressure. (The lowest pressure when your heart relaxes betwe...Read more -
Effects of Skin Pigmentation on Pulse Oximeter Accuracy at Low Saturation
PULSE oximetry theoretically can compute arterial hemoglobin oxygen saturation from the ratio of the pulsatile to the total transmitted red light divided by the same ratio for infrared light transilluminating a finger, ear, or other tissue. The derived saturation should be independent of skin pig...Read more -
What Are the Four Parts of the EKG Machine?
The EKG, or Electrocardiogram, is a machine used to monitor and evaluate possible heart problems in a medical patient. Small electrodes are placed on the chest, sides, or hips. The electrical activity of the heart will then be recorded on special graph paper for a final result. There are four pri...Read more -
Holter monitor
In medicine, a Holter monitor is a type of ambulatory electrocardiography device, a portable device for cardiac monitoring (the monitoring of the electrical activity of the cardiovascular system) for at least 24 to 48 hours (often for two weeks at a time). The Holter’s most common use is f...Read more -
How to clean a Pulse Oximeter and Reusable SpO2 Sensors
Cleaning oximetry equipment is just as important as proper use. For surface-cleaning and disinfecting the oximeter and reusable SpO2 sensors we recommend the following procedures: Turn off the oximeter before cleaning Wipe exposed surfaces with a soft cloth or a pad moistened with a mild deter...Read more -
What does SpO2 mean? What is a normal SpO2 level?
SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen in the blood. More specifically, it is the percentage of oxygenated haemoglobin (haemoglobin containing oxygen) compared to the total amount of haemoglobin in the blood (oxygenated and non-oxygenated haemo...Read more -
why you need to monitor your ECG
An ECG test monitors your heart’s electrical activity and displays it as moving line of peaks and dips. It measures the electrical current that runs through your heart. Everybody has a unique ECG trace but there are patterns of an ECG that indicate various heart problems such as arrhythmias. So w...Read more -
Wireless sensor technology
The iconic image of a hospital patient is a frail figure lost in a tangle of wires and cables connected to large, noisy machines. Those wires and cables are beginning to be replaced by wireless technologies similar to those that have cleaned up the thicket of cables in our office workstations. ...Read more
