It has been reported that Covid-19 patients have presented to hospital with a significant drop in their blood oxygen levels, also known as silent hypoxia. Our fingertip Pulse Oximeter with Bluetooth connection can be used as a home monitoring tool to effectively show when blood oxygen levels decrease beyond normal levels.
### What are the correct blood oxygen levels?
The normal oxygen level in the blood is between 95% and 100%. A symptom of Covid-19 is low levels of oxygen saturation in the blood. It has been reported that Covid-19 patients have been admitted to hospital with oxygen levels as low as 70%. When the oxygen level drops below 93% or 94%, patients should speak to their GP. If the oxygen levels fall below 92%, patients could be at a greater risk of dying. The NHS has advised that medical intervention is needed immediately when blood oxygen levels begin to fall below 92%, and patients should go to A&E urgently.
### What is a Pulse Oximeter and how can it help fight Covid-19?
The oxygen levels in the blood can be measured using our [Fingertip Pulse Oximeter](https://www.fanninshop.co.uk/products/pulse-oximeter-bluetooth-digital-fingertip). This small device attaches to your finger and tells the user how much oxygen is in their blood.[Fannin’s Pulse Oximeter](https://www.fanninshop.co.uk/products/pulse-oximeter-bluetooth-digital-fingertip) is Bluetooth powered and automatically synchronizes blood oxygen level readings to a linked smartphone. Even if you do not feel breathless, your oxygen levels may be low, and if they continue to drop, you may fall seriously ill. A pulse oximeter can detect these changes before it is too late. Doctors in the UK recommend having a pulse oximeter at home for many reasons, including improvement in survival rates, decreased length of stay for hospital admissions and a reduction of pressure on the emergency services.
### How should I use a Pulse Oximeter?
The NHS recommends that a person who is displaying Covid-19 symptoms or a person who has tested positive for Covid-19 should record their blood oxygen levels 3 times daily to help monitor any deterioration in health. [Fannin’s Pulse Oximeter](https://www.fanninshop.co.uk/products/pulse-oximeter-bluetooth-digital-fingertip) can be used at home by both adults and children . Studies in the UK have shown that the device can be potentially life-saving and medics recommend that households purchase one to continuously monitor oxygen levels in the blood in the fight against Covid-19.
