Systolic pressure= maximum instantaneous pressure
Diastolic pressure= minimum pressure
Mean Pressure= the area under the wave form |

| Manual BP Monitoring Vs. Direct Techniques |
|
Definition
| Usually systolic pressure is lower and diastolic pressure is higher |
|
|
Term
| Oscillometric BP Monitoring |
|
Definition
At pressures approximating systolic pressure, the needle begins to oscillate
Maximum oscillation responds with the mean pressure
Diastolic pressure is a calculated value |

Term
| Penaz Technique Of BP Monitoring |
|
Definition
Uses a small cuff to fit around finger
Has an infrared light source which sends light through the digital arteries
The signal is used to rapidly inflate and deflate the cuff to near systolic pressure
Systolic pressure corresponds with cuff pressure |
|
|
Term
|
Definition
Low flow rates can reduce the useful signal
Constant inflation of the cuff to near systolic levels greatly reduces the blood flow distally
Prolonged use can result in ischemic pain |
|
|
Term
| Arterial Tonometric BP Monitoring |
|
Definition
Places transducer directly over an artery
Infers pressure from changes in slight amplitude
Method is very sensitive to motion artifact |
|
|
Term
| Pulse Transit Technique of BP Monitoring |
|
Definition
Pulse transit time is inversely proportional to systolic pressure
Pulses are measured at two different sites with optical transducers
Usually the finger and forhead arteries
Accuracy of this technique is yet to be determined in a variety of clinical settings |
