   Follow these steps: Turn on the pulse oximeter and place it on your fingertip, ideally the middle or index finger. Sit still and avoid moving while the device reads your oxygen levels and heart ...

3. Bradycardia - Wikipedia

   en.wikipedia.org/wiki/Bradycardia

   Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block. Resting heart rates of less than 50 BPM are often normal ...

4. Hypoxemia - Wikipedia

   en.wikipedia.org/wiki/Hypoxemia

   Hypoxemia refers to the low level of oxygen in blood, and the more general term hypoxia is an abnormally low oxygen content in any tissue or organ, or the body as a whole. [2] Hypoxemia can cause hypoxia (hypoxemic hypoxia), but hypoxia can also occur via other mechanisms, such as anemia .

5. Hypoxia (medicine) - Wikipedia

   en.wikipedia.org/wiki/Hypoxia_(medicine)

   Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. [1] Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. [2] Although hypoxia is often a pathological condition, variations in arterial oxygen concentrations ...

6. Athletic heart syndrome - Wikipedia

   en.wikipedia.org/wiki/Athletic_heart_syndrome

   Athletic heart syndrome (AHS) is a non- pathological condition commonly seen in sports medicine in which the human heart is enlarged, and the resting heart rate is lower than normal. The athlete's heart is associated with physiological cardiac remodeling as a consequence of repetitive cardiac loading. [3] Athlete's heart is common in athletes ...

7. Oxygen saturation (medicine) - Wikipedia

   en.wikipedia.org/wiki/Oxygen_saturation_(medicine)

   Oxygen saturation (medicine) Oxygen saturation is the fraction of oxygen -saturated haemoglobin relative to total haemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1]

8. Pulse pressure - Wikipedia

   en.wikipedia.org/wiki/Pulse_pressure

   A pulse pressure is considered abnormally low if it is less than 25% of the systolic value. [2] If the pulse pressure is extremely low, i.e. 25 mmHg or less, it may indicate low stroke volume, as in congestive heart failure. [3] The most common cause of a low (narrow) pulse pressure is a drop in left ventricular stroke volume.

9. Can Dehydration Cause Heart Palpitations and Racing Heart Rate?

   When blood pressure lowers, a person's heart beats faster to ensure oxygen-rich blood reaches vital organs like the brain and kidneys. This increase in heart rate can be perceived as heart ...
