Give the Henderson-Hasselbach for blood pH, aka the bicarbonate buffer system
ph= 6.1 + log HCO3- / (0.03 x PCO2)
how do you convert barometric pressure in inches to mmHg?
multiply by 25.4, bc that's the number of mm in an inch
what anticoagulant is acceptable in a blood gas sample? what vessel is drawn from?
heparin, flushing the syringe with heparin is adequate, very little needed; arterial!
what is fiO2?
fraction of inspired O2
what are 4 primary blood buffer bases in order of concentration ?
BICARBONATE, deoxyHEMOGLOBIN, albumin, and monohydrogen phosphate
what equation can be used to accurately calculate the blood pH, using what values from the blood gas?
the Henderson-Hasselbach; the HCO3- concentration and the dissolved CO2 which is PCO2 x 0.03
