All of your cells need oxygen to create energy efficiently, and your body needs energy to fulfill all of its processes, such as digestion and even thinking. In the first couple of days at altitude you want to see a lower Peripheral Saturation of Blood Oxygen (SpO2) and an elevated heart rate (HR) and respiratory rate (RR). A small device called a pulse oximeter (image 1) measures the oxygen saturation level and pulse/HR. Below is an altitude oxygen chart that extrapolates oxygen percentages to real altitude, which you can use in conjunction with our high altitude tents and mask-based training systems. Clinical Infectious Diseases. Oxygen saturation levels below 90% are considered abnormal. . So a 40 year old should have an A-a gradient less than 14. A pulse oximeter reveals your oxygen saturation level within seconds.

PMC If your results are not normal, your healthcare provider will have you undergo more tests to confirm or rule out a diagnosis. Although the percentage of oxygen in inspired air is constant at different altitudes, the fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen and hence the driving pressure for gas exchange in the lungs.

The sample is then either processed by the respiratory therapist or sent to a lab very quickly where medical laboratory scientists process the sample. Glass KL, Dillard TA, Phillips YY, Torrington KG, Thompson JC. The chart is based on the ideal gas law equation for pressure versus altitude (Barometric Formula), assuming a constant atmospheric temperature of 32 degrees Fahrenheit (0C), and 1 atmosphere pressure at sea level. By quitting, you not only start to protect the lungs from the toxic chemicals, you also start to get rid of that non-functional Haemoglobin that doesnt carry oxygen, boosting efficiencies all round. For instance, we know that the readings of all pulse oximeters around the world are potentially affected by nail varnish, cold fingers and pigmented skin. When they then return to lower elevations, their higher blood count can help boost their performance.
