Oxygen is essential for animal life and measuring pulse oxygen levels can help establish physical health. Hemoglobin levels are important in measuring oxygen pulse, and pulse oxygen sensors use light rays to take measurements. Abnormal levels can signal health problems, but some conditions may misrepresent readings.
Oxygen is perhaps the most crucial element in building and maintaining animal life on earth, as it provides nourishment to body tissues and allows them to function properly. According to many experts, a healthy human being should have an oxygen intake level of between 90 and 100%. Pulse oxygen refers to the amounts of oxygen in the blood and is often measured with a device known as an oximeter. Measuring this vital statistic can help establish an individual’s physical health.
The amount of oxygen in the blood is important because the blood is the main distributor of oxygen throughout the body. A protein substance in red blood cells known as hemoglobin picks up oxygen from an organism’s respiratory organs. It then releases the oxygen to various cells within the body as the blood is pumped. Because of their importance in oxygen transport, hemoglobin levels are an important factor in measuring the oxygen pulse.
Pulse oxygen measurements can be made using sensors that target arterial vessels that carry blood. The heart contracts and dilates arterial vessels as it beats, which is why a pulse oxygen sensor will measure pulse rate and oxygen levels. Pulse oxygen sensors use light rays to take measurements. The amount of light that oxygen reflects can help determine the amount of oxygen particles in the hemoglobin.
A pulse oxygen meter, or pulse oximeter, measures an individual’s blood oxygen level. One end of the device connects to a patient’s finger and the other end connects to a medical monitor, where the readings can be viewed. Individuals can also track their stats at home by purchasing a portable oximeter.
Abnormal pulse oxygen levels can signal many problems. A patient recovering from any serious ailment will typically have blood oxygen monitoring, as a low reading can indicate any number of complications. In particular, conditions of the heart or respiratory system can negatively affect blood oxygen saturation, leading to symptoms such as fatigue, mental disability, and difficulty breathing. Individuals in critical environments, such as divers or pilots, can also benefit from efficient pulse oxygen readings. If blood oxygen impairment is found, assisted breathing devices may be required.
However, some conditions may misrepresent a pulse oxygen reading. For example, a disorder called anemia reduces the overall amount of red blood cells and can therefore cause the oxygen pulse reading to read normally when in reality the levels are low. Conversely, high altitudes can deflate pulsed oxygen levels, but not in a harmful way. Some individuals even have a lower than average oxygen pulse as the norm.
