Values to know Flashcards
Cardiac index (what is, avg at rest)
Cardiac index normalizes cardiac output for size. Avg at rest is 3.1 liters/min/sq m
Venous pressure
5 mmHg
Right atrial pressure (avg)
2 mmHg
Right ventricle pressure (systolic)
25 mmHg
Right ventricle pressure (end diastolic)
2 mmHg
Pulmonary artery pressure (systolic)
25 mmHg
Pulmonary artery pressure (diastolic)
10 mmHg
Pulmonary artery (avg, also, closer to systolic or diastolic pressure and why?)
15 mmHg (it’s closer to diastole b/c we spend more time in diastole)
Pulmonary wedge (avg, also, what is?)
Pulmonary wedge is a balloon that occludes the pulmonary artery and is equivalent fo the L atrial pressure. 6mmHg
Left atrial pressure (avg)
6 mmHg
Left ventricle pressure (systolic)
120 mmHg
Left ventricle pressure (diastolic)
6 mmHg
Brachial artery pressure (avg)
95 mmHg
Nl PR-interval
0.12 - .20 seconds
Nl QRS interval
0.07 - 0.10 seconds
Nl QT-interval
0.25 - 0.43 seconds
Tachycardia
100 bpm (less than 3 boxes between R waves)
Bradycardia
60 bpm (more than 5 boxes between R waves)
Nl blood potassium levels, hyperkalemia, and hypokalemia
Nl blood K: 3 - 5 mmol. Hyperkalemia: >5.5, Hypokalemia: <3
Nl hematocrit level
35-50% hematocrit in blood is nl
