| Question | Answer |
| O2 Capacity Formula | Hemoglobin X 1.36 |
| Oxygen Content | O2 Capacity X O2 Saturation |
| Hemoglobin x 1.36 | O2 Capacity |
| O2 Capacity x O2 Saturation | Oxygen Content |
| AVO2 Difference | (AO sat X 1.36 X hemoglobin) - (PA sat X 1.36 X hemoglobin) |
| (AO sat X 1.36 X Hemoglobin) - (PA sat X 1.36 X hemoglobin) | AVO2 Difference |
| Fick Cardiac Output (L/min) | O2 consumption (ml/min) DIVIDED BY AVO2 difference X 10 O2 consumption ml/min DIVIDED BY AVO2 Content difference MULTIPLIED BY 10 |
| For the Fick CO what do you need to multiply the AVO2 by to convert from ml/min to L/min? | 10 |
| O2 consumption range | 220-290. 250 is considered the average. |
| Cardiac Index Formula | CO/BSA |
| Cardiac Output DIVIDED BY the Body Surface Area equals .... | Cardiac Index. The lower the # the sicker the patient. |
| Body Surface Area Formula | Height X Weight X Hemoglobin |
| Stroke Volume is what? | Amount of blood pumped by the left ventricle of the heart in one contraction |
| Stroke Volume (SV) Formula | Cardiac Output X 1000 DIVIDED BY Heart Rate SV=CO X 1000 / HR |
| CO X 1000 / HR | Stroke Volume |
| Pulse Pressure | The difference between the systolic # and the diastolic # |
| MAP (Mean Arterial Pressure) | Aortic Systole MINUS Aortic Diastole multiplied by 1/3 PLUS the Aortic DIASTOLE |
| Aortic Pulse Pressure X .33 + Diastole= | MAP (Mean Arterial Pressure) |
| MPA (Mean Pulmonary Artery Pressure) | Pulmonic Systole MINUS Pulmonic Diastole MULTIPLIED BY 1/3 PLUS Pulmonic Diastole |
| Pulmonic Pulse Pressure X .33 + pulmonic Diastole = | MPA (Mean Pulmonary Artery Pressure) |
| Why is the Hakkai Formula used | For quick approximation only of the valve area |
| Hakkai Formula | Valve Area = CO / Square Root of the mean gradient (aortic or mitral) |
| Cardiac Output DIVIDED by the Square Root of the mean gradient (aortic or mitral) | Hakkai Formula for Valve Area |
