Vq mismatch - Study guides, Class notes & Summaries

A-a gradient formula and normal range Correct Answer-PAO2- PaO2 PAO2 = FiO2 x (Patm- Ph20) - (PCo2/RQ) PAO2 = 150 - (PCO2/0.8) Normal is 10-250 Increased A-a gradient Correct Answer-- VQ mismatch (ex. COPD, PE, PNA) - responds to 100% O2 - Right to left shunt (ex. ARDs - Decreased diffusion (ex. ILD) Normal A-a gradient Correct Answer-- Low mixed venous O2 (ex. high altitude) - Hypoventilation (ex. drug OD) Acute vs chronic pH changes (hypercapnia/respiratory acidosis) Correct Ans...

Normal Blood Gas Values - ANS pH: 7.35 - 7.45 PaO2: 80 - 100 mmHg PaCO2: 35 - 45 mmHg ventilation - ANS ability to clear CO2 oxygenation - ANS the process of delivering oxygen to the blood causes for CO2 increase - ANS -CO2 is being produced but not being exhaled quickly enough -increase in CO2 by increased metabolism like fever or exercise -PaCO2 in ABG is increased therefore pH decreases -as CO2 accumulates, peripheral and central chemorece...

BCEN- respiratory Questions and answers, 100% Accurate. VERIFIED. ventilation - -movement of air in and out of the lungs Diffusion - -the process by which molecules of gas move from an area of higher concentration to an area of lower concentration (alveolar and capillary). if ventilation & perfusion match you get diffusion. If they don't match- VQ mismatch Perfusion (Q) - -the process of transporting gases to the body (capillary) via the circulatory system. dead space ventilation ...

Which of the following equipment is most helpful at measuring FRC in a patient who has significant non-ventilated lung spaces? A. peak flow meter B. plethysmograph C. helium analyzer for a helium dilution test D. nitrogen analyzer for a nitrogen washout test - correct answer The correct answer is : B Explanation : You can determine FRC in three different ways - body box, nitrogen washout, or helium dilution. If someone has non-ventilate...

NSG4330 Weeks 1-4 (Resp Failure, ACS, HF, Renal Failure) Practice Questions and Answers What are the 3 processes of effective gas exchange? - Correct Answer️️ -Ventilation, perfusion, diffusion - any problems can result in Hypoxemia or Hypercarbia What is Respiratory failure? - Correct Answer️️ --one of both gas exchanging functions are inadequate - amount of O2 transferred to blood is insufficient (hypoxemia) or amount of CO2 removed from lungs is inadequate (hypercapnia) Definit...

NURS 6501 Mod 1-4 Questions & Answers Solved 100% Correct!! Why is HDL considered good cholesterol? It's able to remove cholesterol from artery plaques and recycle it back to the liver. Why is HDL consider good cholesterol HDL is considered good cholesterol because it collects excess cholesterol in the body cells and transports it to the liver where it is excreted. HDL carries 20 to 25% of total plasma cholesterol. Explain the role inflammation has in the development of atherosclerosis ...
