Choose the correct statement regarding end-tidal carbon dioxide (ETCO2) measurement during resuscitation.Question 51Answera.During CPR, survival is increased if ETCO2 is kept below 10 mmHg.b.There is a strong correlation between coronary perfusion pressure and ETCO2.c.Return of spontaneous circulation (ROSC) results in an immediate decrease in ETCO2.d.In a normal patient, ETCO2 is approximately 15-20 mmHg lower than PACO2.

All statement concerning ETCO2 are true exceptMeasures oxygen status of patientProvide indication on effectiveness of CPR during cardiac arrestNormal level in perfusing patient is 35-40Monitors Endotracheal tube placement

The nurse is caring for a 70-kg patient in septic shock with a pulmonary artery catheter. Which hemodynamic value indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues?No sweat, you're still learning!Arterial lactate level of 1.0 mEq/LCardiac output of 2.5 L/minMixed venous (SvO2 ) of 40%Cardiac index of 1.5 L/min/m2

What are the partial pressures of oxygen and carbon dioxide in blood traveling via systemic arteries to tissues?Multiple ChoicePO2 = 40 mmHg and PCO2 = 45 mmHgPO2 = 95 mmHg and PCO2 = 40 mmHgPCO2 = 104 mmHg and PO2 = 40 mmHgPO2 = 95 mmHg and PCO2 = 75 mmHg

is the dissolved concentration of O2 in a normothermic patient, with a PaO2 of 90 mmHg?

In a healthy person, the partial pressure of carbon dioxide (pCO2) in systemic arterial blood is equal to the pCO2 in the alveoli.
