Document Summary
Muscles can use hemogloblin for muscle contraction. If co2 is low, and conditions are alkaline, curve will shift to the right. If co2 high, it helps o2 unloading & vice versa. If temp is high, curve will shift to right. When you heat a gas, it expands and pressure falls. Apnea: no breathing due to co2 buildup (co2 regulates breathing not o2), sleep apnea. O2 will play a role only if po2<60mmhg (hypoxia --> less o2 in the air, New born respiratory disease (sids) breathing control centers in medulla fail to dectect or respond to low co2. Dysphea: air hunger (laugh, hiccup, sneeze, cough, yawn) Shallow water blackout: person may pass out and no breath because they do not have enough co2 before diving in water. Person going up, nitrogen turn into bubbles that choke the capillaries (n2 narcosis, dysbarism, diver"s sickness, caissanis disease, bends) In scuba diving, you replace nitrogen with helium (thermal conductivity is high)
