Oxygen Saturation (SpO2) & Pulse Oximeters
Pulse oximeter is a non-invasive device for measuring arterial blood oxygen saturation (SpO2) level and pulse rate. Oximeters are used by people with breathing and heart problems, such as asthma and COPD.
Meaning of Blood Oxygen Saturation SpO2
Blood oxygen saturation level (SpO2) is a measure of the amount of oxygen carried in the blood. SpO2 is expressed as a percentage of the maximum amount oxygen that blood can carried.
Pulse Oximeter as a Sleep Apnea Monitor
A full-blown sleep apnea study can be expensive and inconvenient. Nowadays with the advances in pulse oxymetry one can adopt a do it yourself attitude and test at home sleep apnea. It just takes a good overnight recording pulse oximeter and reading about the characteristics of an apnea episode. It is recommended that you use a pulse oximeter to do a preliminary study and with your results you can talk to your doctor to determine if a polysomnogram is required. In many cases, using the pulse oximeter is sufficient except for borderline cases.
Understanding Heart Arrhythmia with your home ECG monitor
This article will give you a better understanding of what an ecg strip means and it shows you what to look for when analyzing results from a personal or hospital ecg / ekg. You will be able to see pictures and graphics of the most common conditions detected by an ecg machine. We show you from the normal sinus rhythm to the abnormal ecg strip examples like Tachycardia, Bradycardia, Premature beat, Bigeminy, Missed beats, and Ventricular arrest. This is a good starting point to familiarize yourself with some of the ecg terminology and diagnostics.
