| Question | Answer |
| Normal oxygen sat. | 92 to 99 |
| On the oxyhemoglobin dissociation curve a shift to the left means | hypoxemia, hypothermic, alkalosis the hemoglobin is holding onto oxygen |
| On the oxyhemoglobin dissociation curve a shift to the right means | patient is hyperthermin or pao2 is slightly highter, hemaglobin lets go of oxygen easier |
| You do not want your pao2 less than | 60 |
| how is the right bronchi different than the left | shorter and more direct angle |
| The movement of air between the alveoli and the atmosphere | Ventilation |
| Movement of CO2 and O2 between alveoli and capillaries | Diffusion |
| movement of O2 from the lungs to the tissues and from the tissues to the lung | transport |
| a measurement of the distensibility of the pulmonary tissue | Lung compliance |
| a measurement of the opposition of flow of gases through the airway | airway resistance |
| increases the work of breathing and requires more pressure to ventilate the patient | todecreased compliance or increased resistance |
| tidal volume X resp rate = | minute volume |
| air moved in and out of the lungs in one min | Minute volume |
| normal VE (minute volume) | 6-10 |
| results when resp rate or tidal volume are inadequate and there is an increase in PaCO2 and hypoventilation occurs | low VE less than 6 |
| response to high CO2 production, CNS response in attempt to maintain normal PaCO2 | high VE greater than 10 |
| High VE and and increase in PaCO2 equals | patient cant meet ventilatory demand leading to resp failure |
| optimal gas exchange occurs when thre is ideal matching of | ventilation and perfusion |
| shunt blood from the right heart to the left heart with out picking up O2 | anatomic shunt |
| not enough ventilation but good perfusion | Physiologic shunt |
| more ventilation with poor perfusion | physiologic deadspace |
| primary cause of hypoxemia | shunting |
| treatment for a VQ mismatch | cough, suction, lung expansion therapy and mobilize the patient |
| esitmated shunt refers to | PaO2/FiO2 ratio |
| the oxygen dissolved in the serum is refered to | PaO2 |
| the oxygen combined with Hgb is refered to as | SaO2 |
| this tells the amount of tissue perfusion | SvO2 |
| the measure of total amount of O2 carried in the blood including the plasma | CaO2 |
