1) Why would the ETCO2 be decreased in a patient with a big pulmonary embolism? I can understand why in a small PE the ETCO2 would be a lower value due to hyperventilation, but shouldn't the ETCO2 be high in a big PE due to a severe V/Q mismatch?
2) The ETCO2 will match the PaCO2 in a healthy patient. Why might it not correspond in a person with cardiovascular issues?
3) It is correct that in a patient with severe pulmonary edema the ETCO2 would be elevated, right?
