What Is A Normal Pulse Oximeter Reading
Around 95%...: Between exacerbations, an asthmatic's pulse ox is normal since airway obstruction in asthma is reversible by definition. During an asthma exacerbation, the airways are obstructed/inflamed to a certain degree depending on the severity of the exacerbation and the pulse ox may decrease. Supplemental oxygen may then be necessary to maintain oxygen delivery to vital organs/tissues. ...Read moreSee 1 more doctor answer
95-100%: In normal healthy patients with normal lungs and hearts, pulse oximetry doesn't start to really drop until the anaerobic threshold is reached, and that only happens during very intense exercise. But be careful - pulse oximetry readings during exercise are problematic due to motion artifact and altered perfusion in the fingers (where it's usually measured). ...Read more
If someone is having a heart attack. Would the pulse oximeter show an oxygen sat level below normal range?
Not necessarily: If the heart attack is huge, the heart will not pump effectively and blood will not circulate normally, causing a low oxygen saturation. More commonly, the heart attack will be smaller and the heart will continue to pump effectively enough to get blood to the lungs and then to the body, keeping the oxygen saturation normal. ...Read moreSee 1 more doctor answer
Same as Exercise: This will vary from one person to another but you can think of hyperventilation as being similar to an episode of strenuous exercise, with a heart rate that will be similar to a state of exertion. For adults, heart rates in the 120s to 150s would not be unusual, sometimes higher. ...Read more
Looking good: On Feb 5, 2014, the guidelines were updated for blood pressure: 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults those younger than 30 years recommends a BP of less than 140/90 mm Hg for those groups based on expert opinion. ...Read moreSee 1 more doctor answer
Depends on Norms: Pft normals are based on your age, height, weight, race with what is normal for this group. Normals change with age. What may be.Normal for you, could be different from published normals. With lung conditions, following the lung functions over time is often very useful. With pfts we often look at forced vital capacity (fvc), and various flow rates as well as the shape of the curves on graphing ...Read moreSee 1 more doctor answer
Normal For You: An "average" blood pressure is 120/80 which means 120 mm mercury systolic (full heart pump) and 80 mm mercury diastolic (heart at rest between beats). Many other factors enter into the number which makes it higher or lower, but normal for you. Example: athletes BP is usually lower, the elderly have higher bp's but both are prefectly fine. Find what is normal for you. Extremes are bad. ...Read more

Maybe: A little high is not a big deal if you have no other risk factors, and can probably be taken care of with increased activity and a better diet. If you are diabetic, already have coronary disease, or a history of premature coronary artery disease in your family - medication may be needed. ...Read more
