4. What is PEEP? PEEP stands for Positive End Expiratory Pressure. PEEP is a setting used for ventilation in which positive pressure is maintained during expiration to increase the volume of gas remaining in the lungs at the end of expiration. This helps to reduce the shunting of blood through the lungs and improves gas exchange (Kacmarek 2017). 5. Which measurements are used to evaluate the presence of each of the four types of hypoxia’s below? Provide the normal values for each of the measurements used to evaluate their presence. Blood gas analysis and oximetry is used to measure the levels of oxygen in the blood. a. Hypoxic- caused by low levels of oxygen supply due to altitude and airway obstruction. There is a reduced amount of O2 in the inspired air, so there will be a reduced PO2 in arterial blood. b. Anemic- caused by reduced oxygen being carried by the blood. The amount of O2 in arterial blood is normal but there is a reduced amount of hemoglobin available to carry O2, so the arterial PO2 is normal. c. Stagnant- caused by diminished blood flow and transport issues such as a decrease in cardiac output. There is a normal PO2 and hemoglobin concentration but

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
