[Correct Ans Is: - B Wave
Normal Icp Has A Pressure Of 5 To 15 Mm Hg. An Elevation Of Icp To 20 To 50 Mm
Hg Occurring Every 30 Seconds To 2 Minutes Is A B Wave. An Elevation Of Icp To 50
To 100 Mm Hg Lasting Longer Than 2 Minutes Is An A Wave. An Elevation Of Icp To
20 To 25 Mm Hg Every 4 To 8 Minutes Is A C Wave.
What Three Things Tell You Heart Catheter Has Flipped Back Into Right Ventricle?
