Q

What is pulse pressure?

A

the pressure in arterial system

19
Q

Pulse pressure in humans?

A

40 mmHg / 5.3 kPa

20
Q

Normal Diastolic pressure in humans?

A

75-80 mmHg / 10.0-11.0 kPa

21
Q

Why does edema happend with Ringer’s solution?

A

Protein free solution pass unhindered trough blood vessel walls to interstices

22
Q

What is the effect of pharmacological consentrations of epinephrine? And which receptors does it influence?

A

Vasoconstriction all over body, trough α1 adrenergic receptors

23
Q

Equation for effective filtration pressure?

A

Peff = Pheff – Poeff

24
Q

Equation for flow rate in the capillaries?

A

Q = Peff x CFC

25
Q

Factors of the diffusion rate?

A

conc. gradient and transit time of substance, and permability and diffusion area

26
Q

Method of measuring blood pressure?

A

Indirect, by auscultatory method, or by digital method

27
Q

How to determind diastolic pressure?

A

dissapperance of the tapping sound when releasing the cuff pressure

28
Q

ISF, what does it depend on?

A

blood pressure, hydrostatic pressure, oncotic pressure and tissue turgor

29
Q

Myogen, is it dependent on the CNS?

A

Independent

30
Q

What happens when you get a local hypoxia?

A

metatrioles contract due to increased hydrostatic pressure

31
Q

Is pulse pressure age dependent? Why?

A

Yes, because systolic increase and diastolic decrease by age

32
Q

Equation for mean arterial pressure?

A

(Pavarage = (Psystolic + 2xPdiastolic) / 3

33
Q

How to measure systolic pressure?

A

First sound when releasing pressure in cuff

34
Q

How to measure blood pressure by ausculatory method?

A

by using the Riva-Rocci sphygmomanometer

35
Q

Effect of prolonged perfusion with ringer’s solution?

A

Oedema

36
Q

How can you decrease edema in the Trendelenburg preparation?

A

..

37
Q

What blood cell type is mainly in mural flow?

A

White

38
Q

Effect of hypoxia after local blood perfusion

A

The higher the O2 consumption of a tissue, the faster

will be the drop of pO2 (partial pressure of oxygen).
