30
Q

Calculate afterload

A

SVR = (Map - CVP) x 80 / CO

31
Q

Drugs to increase SVR:

A

32
Q

Drugs to decrease SVR:

A

Nitroprusside
NTG

33
Q

Calculate PVR:

A

1/6 of SVR

34
Q

What is normal PVR

A

100-250 dynes/sec/cm5

35
Q

a naturally occurring phenomenon in which the arterial pulse pressure falls during inspiration and rises during expiration due to changes in intra-thoracic pressure secondary to negative pressure ventilation (spontaneously breathing).

A

SVV

36
Q

Normal SVV

A

10-15%

37
Q

Oxygen Sat of venous blood is called

A

SVO2

38
Q

Normal SVo2

A

60-80%

39
Q

The nurse caring for a patient with an arterial line notes the reading of 182/130. The priority action at this time will be:

  1. Notify the MD
  2. Increase the nitroprusside IV gtt
  3. Verify the transducer level
  4. Verify the flush solution
A

3 is my guess

40
Q

The patient with a FloTrac monitor is noted to have a SVV of 19%. The nurse can anticipate which treatment ordered?

  1. Fluid bolus
  2. Dopamine IV gtt
  3. Nitroglycerine IV gtt
  4. Lasix per IV
A

1

41
Q

The nurse notes a SVR of 550 dynes/sec/cm-5. This is an indicator of:

  1. Vasoconstriction
  2. Increased right heart preload
  3. Increased left heart preload
  4. Vasodilation
A
