|
Calculate Pulse Pressure.
|
Systolic pressure - Diastolic pressure
|
|
|
Define the Systolic pressure.
|
The pressure in the arteries at the peak of ventricular ejection
|
|
|
Define the Diastolic pressure.
|
The pressure during ventricular relaxation

Define the Apical Pulse.
|
Actually the counting of heartbeats
|
|
|
Define the Pulse Deficit.
|
When there is any large difference between the apical pulse and the radial pulse -> indicates cardiac impairment (ex. a weakened heart)
|
|
