How a Durasensor Detects Low Blood Oxygen

Do you have low blood oxygen? If so then you should consider a durasensor such as at The device can detect when your blood’s oxygen level has dropped below a critical threshold, which is 90%.

It’s also helpful if you can detect the various symptoms of low blood oxygen or hypoxia. There are various symptoms to watch out for.

In particular, watch out for a fast drop in oxygen saturation level. This can happen during particular times such as when you have a bad cold or flu. It can be a sign that your blood’s oxygen level is dangerously low. If you have long-term oxygen therapy you should contact your doctor if your durasensor’s oxygen setting isn’t containing your saturation effectively and you feel ill. You should also contact the supplier of the device if it’s not functioning properly.

What figures should you watch out for? If your resting pulse rate is higher than 100 or your low pulse is lower than 40 it’s important to contact your doctor as soon as possible. Your doctor can inform you of your personal pulse ranges.

If you experience a serious breathing attack you still might have an oxygen level that is normal. If you experience major shortness of breath, high pulse rate, or wheezing contact your doctor immediately. Even if your oxygen saturation level is normal it’s important to contact your physician in that case.

Here are some steps to consider if you experience such symptoms:

  1. Lower shortness of breath

If your lungs are over-inflated this puts your breathing muscles at a big disadvantage. That, in turn, boosts the load to breathing. This is often referred to as “dyspnea” or more effort to breathe. You can lower the shortness of breath often by using slow and deep breathing/exhaling.

Practice using the oximeter using pursed-lip breathing. Breathe in for 2-3 seconds, then exhale for 5-6 seconds. Find a breathing rate that’s comfortable. Observe your oxygen saturation level rise at a particular oxygen setting.

You might also want to try this process inhaling room air. The oxygen saturation will be acquired by stopping the oxygen for 10-20 minutes. That’s how long it takes up to use the extra oxygen in your lungs after you exhale.

  1. Pursed lip breathing

This involves exhaling slowly against your tightened lips like you’re whistling. This act can improve your breathing efficiency in several different ways. If you use pursed lip breathing, you can breathe in a way that’s deeper and slower. It also helps to empty your lungs more thoroughly. This is very important in the case of COPD/emphysema. In that case over-inflating, the lung is a big problem.

Some patients want to learn how long the oxygen saturation level stays above 90% after the oxygen is switched off. This provides more confidence when there’s a short-term stoppage of oxygen flow.

After you’ve completed mastered the pursed lip breathing it’s time to try it with exercise. Use the oximeter to walk around your house then around the block. Use pursed lip breathing for a minimum of 100 yards. This method will treat your shortness of breath and boost your oxygen saturation level.
