An in vivo value of pH < 6.9 or pH > 7.8 can be life threatening. Differences in only a few tenths of a pH unit can cause illness or death. So it is important for our body system to maintain its physiologic pH. Acidosis is the condition when pH drops too low. Alkalosis results when the pH is higher than normal. Two species are required in a buffer solution. One is capable of reacting with OH- and the other will react with H3O+ and they must not react with each other. Many buffers

Thermoregulation is a critical physiological function that is closely associated with the neonate’s survival. Extremely low birth weight infants have inefficient thermoregulation due to immaturity and care giver procedures such as umbilical line insertions‚ intubations‚ and chest xrays can lead to heat loss as well. As a result‚ infants may exhibit cold body temperatures after birth and during their first 12 hours of life. Thermoregulation plays a unique and crucial role in the nurturing and development
