NURS 223 Respiratory || Well-Enlightened.

It is the VOLUME of oxygen physically dissolved in the plasma in the arteries. The higher the _______, the higher the amount of oxygen dissolved in the blood. correct answers The partial pressure of oxygen. the PERCENTAGE of oxygen that could be carried if all hemoglobin held the maximum possible amount of O2. correct answers Oxygen Saturation The amount of oxygen that actually COMBINES with hemoglobin depends on both the ____________ and the ________________ in the blood. correct answers partial pressure of oxygen amount of hemoglobin Define: The percentage of oxygen participating in gas exchange. correct answers Fraction of Inspired Oxygen Conversely, the Partial pressure of oxygen is the physically dissolved oxygen in the blood. Therefore, the ration compares the amount of oxygen dissolved in the blood divided by the the amount of blood actually participating in gas exchange. What should the PaO2/FIO2 ratio be (number)? correct answers Greater than 350 mm Hg How is FiO2 expressed? correct answers As a decimal. Should be less than .5 to avoid oxygen toxicity. It is the decimal version of SpO2. What does the P/F ratio measure? correct answers The extent of the ventilation/perfusion mismatch. What's the Bicarbonate range? correct answers 24-28 Less 24 = acidosis More 28 = alkalosis What's the pH range? correct answers 7.35-7.45 What's the CO2 range? correct answers 35-45 < 35 = alkaline > 45 = acidosis This equation helps determine degree of respiratory failure. It is MINUTE VENTILATION..what is it? correct answers TV X RR = MV the VOLUME of air inspired/expired per minute. The VOLUME of air inspired/expired per minute. correct answers Minute Ventilation Inflate the lungs by exerting positvie pressure on the airway, pushing air in, similar to a bellows mechanism, forcing alveoli to expand during inspiration. Expiration occurs passively. correct answers Positive Pressure Ventilators
