  • Primary function of respiratory system is transport of O2 and CO2. This requires the four processes collectively known as respiration: 1.      Pulmonary ventilation is the movement of air into and out of the lungs (breathing). This involves gas pressures and muscle contractions.2.      External respiration is the exchange of O2 (loading) and CO2 (unloading) between blood and alveoli (air sacs). 3.      Transport of respiratory gases between lungs and tissues. 4.      Internal respiration is gas exchange between blood and tissue cells.  Cellular respiration - the includes the metabolic pathways which utilize O2 and produce CO2, which will not be included in this unit.

    heparin is Mrs Perkins receiving each hour?
  • 161. Heparin Infusion
    880 units
    20,000 divided by 500 = 40 units
    If 22 ml are infused per hour, then 880 units
