What are the 3 main types of fluids?
colloids (contain large molecules that cant pass cell membrane, remain in intravascular compartment and expand intravascular volume - draw fluid from extravascular spaces due to increased oncotic pressure)
crystalloids (contain small molecules that flow easily across cell membranes, transfer from blood into cells and body tissues. Increase in interstitial and intravascular. Isotonic, hypotonic, hypertonic)
blood products
