Document Summary
Nitrogen narcosis - going down: gas pressures increase with depth, pn2 increases and n2 is dissolved in the blood, high [n2] decrease nerve conduction, n2 solubility isn"t high because there is so much of it in the atmosphere. Nitrogen narcosis - going up: there is high pn2 in blood as you start to go up, nitrogen will bubble in the body if you go up to fast. If breathing is irregular, pressure between blood and lungs mat become too similar. 11:05 am ph and h: ph scale (1-14) is logarithmic, 1 unit change in ph is a 10x change in h+ Stomach acid (hcl) = 1. 0: blood = 7. 1, co2 + h2o h2co3 h+ + hco3, buffering occurs because h+ has a high affinity to hb when po2 is low. Additional control of ph: kidneys also buffer, remove h from blood - slow process, phosphate buffering system, forming sodium phosphate and adding another h to it as blood passes through.
