Pulse oximeter devices have been around for a long time. In reality, more than four decades have passed since the first devices were manufactured for the hospital setting. However, what you may have seen in hospital settings over forty years ago is definitely not what you see today. There has been a complete transformation that has completely changed the entire landscape of the medical device market. The old systems were very large and bulky and could not be easily moved. They used to be assigned to a patient’s room and offered functions such as measuring pulse rate and oxygen saturation. In fact, this is something that is common to all pulse oximeter devices in which they all accurately measure pulse rate and blood oxygen saturation.
Then, through generations of technological advances in pulse oximeter devices, they became significantly more portable and mobile. Today’s devices are so small that you can simply put them in your pocket. They allow you to easily go where you want to go while still having easy access to your vital signs measurement. Some of the people who have particularly benefited from this device are actually those with heart conditions. This allows them to be on the move without worries and whenever they consider it appropriate they can take their pulse to check their heart. If their levels are at an abnormal reading, an alarm will sound to alert them to take additional steps to remedy the situation. The most beneficial aspect of the device is that it offers a continuous reading of pulse rate and oxygen saturation. This means you can leave it on your finger and it will work continuously to give you real-time readings.
