PEEP EXAM QUESTIONS WITH 100% CORRECT ANSWERS LATEST UPDATE . Functional residual capacity - Answer Amount of air remaining in lungs at end of exhalation lung and chest wall compliance - Answer FRC is determined by _____ anything that reduces outward mobility - obesity, ascites, constrictive bandages - Answer What reduces chest wall compliance? anything that reduces volume of the lungs - pulmonary edema, fibrosis, consolidation, increased intra-abdominal pressure - Answer What reduces lung compliance average pressure above baseline during a total respiratory cycle - Answer What is Mean airway pressure increase Mean airway pressure - Answer What is one approach to improving oxygenation after FiO2 has already been increased Pip, Peep, I:E ratio, RR, inspiratory flow pattern - Answer 5 factors that affect MAP affects mean alveolar pressure increasing alveolar recruitment and oxygenation - Answer Why is Map important flow resistors & threshold resistors - Answer 2 devices used to apply PEEP expiratory flow, expiratory retard devices - Answer Flow resistors direct __________ through an orifice or resistor (such as a screw clamp) and acts as _________. pressure - Answer Flow resistors generate a higher _____ w/ a higher rate of flow. Flow - adjusts pressure based on flow, pressure - constant pressure - Answer Main difference between flow resistors and pressure resistors. pressure resistor - Answer Device that provides a constant pressure throughout expiration regardless of the rate of gas flow. pressure in patient's lungs matches preset PEEP - Answer Threshold resistors stops gas flow when _____ PEEP EXAM QUESTIONS WITH 100% CORRECT ANSWERS LATEST UPDATE Underwater seal, weighted ball, spring loaded valves, magnetic valve, Balloon-type exhalation valve - Answer What are the different types of threshold resistors? Underwater seal - Answer Type of threshold resistor where expiratory limb is submerged in a reservoir of water a distance equal to the amount of PEEP required evaporation causes lower PEEP levels - Answer Main problem w/ Underwater seal the higher the PEEP - Answer For Underwater seal, the further the tube is inserted in the water, ______________ Bubble CPAP systems in NICUs - Answer Where are Underwater seals still used today
