Can /fit/ educate me on some of the possible effects of blood loss at high altitude (say 18k feet, using this here chart)? Say a reasonably acclimatized lowlander got shivved, but not fatally. How long would it take them to clot? Would they? Would they die of oxygen deprivation from blood loss first or from hypoxia? About how long do you think it would take? What if they were moved to a lower altitude quickly?

Oh, well that's all right. I was afraid the stabbing had already taken place.

How reasonably acclimatized? After 10 days someone has begun to adapt to high altitudes by producing more red blood cells and myoglobin and capillaries. I don't know how long it would take to get totally accustomed to it, but they would probably bleed out at a normal rate if they had been there for any longer than a couple of weeks.

>>Pathophysiology Character and Clinical Signs of Wounds at High Altitude: The adverse circumstances with harsh climates at low atmospheric pressure cause pulmonary artery hypertension, low capacity of lungs, hypoxemia, and overload of the right heart. As a result, pulmonary edema appears. At sea level, the percentage of oxygen in the atmosphere is 20.95% and the pO2 at sea level is 159.2 mmHg. At an altitude of 10,000 feet (3,048 meters), where the barometric pressure is 523 mmHg, the percentage of oxygenremains 20,95%, but the pO2 decreases to 109.6 mmHg (pO2 = 20.95% X 523 mmHg = 109.6 mmHg).

>>The main clinical appearance of victims are due to hypoxemia. It is caused by an inadequate pO2 in inspired air and a ventilation defect with the result of in an oxygen deficiency in the tissues. The condition of victims is usually serious due to a majority of them presenting with penetrating wounds. Penetrating wounds cause this form of hypoxia with blood loss and anemia. The initial respiratory system response to hypoxia in the wounded, is an increased rate and depth of ventilation. Hyperventilation results in reduction of pCO2 causing respiratory alkalosis and a shift of the oxyhemoglobin association curve to the left. The result allows an increased binding of oxygen with hemoglobin for transport to the tissue.

>>At an altitude of 20,000 feet (6,096 meters), the oxygen saturation of the hemoglobin, drops to 70%, and the physical findings include an inability to remain upright, jerking of upper limbs, seizures, unconsciousness, coma, and death. For these reasons, then, the general condition of the wounded is quite serious.

tl;dr they would not be doing very well at all
