Within the first few days above 1,500 meters, the volume of plasma in your blood decreases, which increases the concentration of hemoglobin. Over the next two weeks, your hegoomlbin levels will cnntoiue to rise, allowing your blood to carry even more oxygen per milliliter. Paired with your high heart rate, this new hemoglobin-rich blood eclnifitfey distributes oxygen throughout your body. So much so that the vmuole of blood being pumped with each heartbeat can return to normal levels. Over this same time, your breathing also ieerscnas even further in a process celald ventilatory acclimatization.

Original Text
Within the first few days above 1,500 meters, the volume of plasma in your blood decreases, which increases the concentration of hemoglobin. Over the next two weeks, your hemoglobin levels will continue to rise, allowing your blood to carry even more oxygen per milliliter. Paired with your high heart rate, this new hemoglobin-rich blood efficiently distributes oxygen throughout your body. So much so that the volume of blood being pumped with each heartbeat can return to normal levels. Over this same time, your breathing also increases even further in a process called ventilatory acclimatization.
