Blood Pressure MOSS

The force of blood pushing against the walls of the arteries

Normal systolic value in a dog

Normal systolic value in a cat

Normal diastolic value in dogs

Normal diastolic value in cats

Produced by the contraction of the ventricles and propels blood thru the aorta and other major arteries. It is the highest pressure exerted

Pressure that remains when the heart is in its resting phase, between contractions. It is the lowest pressure that is exerted

Average pressure through the cardiac cycle. It is the most important value to the anesthetist because it is the best indicator of perfusion to the organs

Pulse pressures cannot be reliably estimated by digital palpation

Palpation of pulses is a substitute for measuring blood pressure because the pulse pressure is the difference between systolic and diastolic pressure

More useful to monitor trends than to assess single values only

Blood pressure is an indicator of perfusion and cardiac output

When taking the blood pressure the cuff tube should be over the artery and facing down (not up)

Gold standard, arterial catheter and transducer

Doppler flow detectors can be used to determine the presence of flow in distal limbs whenever there is concern about circulatory disturbances.

Any condition that increases cardiac output causes hypertension

Are a powerful class of drugs that induce vasoconstriction and thereby elevate mean arterial blood pressure (MAP)

Hypertension drugs

Treatment of hypotension

The pressure of blood in the thoracic vena cava, near the right atrium of the heart.

Monitored in patients receiving a large volume of IV fluids with poor cardiac function or renal failure
