Question 6

key management for marfan

Answer 6

AVOID HTN
AVOID TACHY
AVOID VALSALVA

Question 7

ongoing IUP, untreated uterine rupture, unresolved inversion, current cervical cancer, uterine anomaly, purulent fluid, for CD- less than 3 cm dilated prior to placement

Question 8

how to measure preload left side of heart

Answer 8

pulmonary catheter wedge pressure

Question 9

how to measure afterload of LV

Answer 9

systemic vascular resistance, BP

Question 10

stroke volume controlled by?

Answer 10

preload
afterload
contractility

Question 11

how to measure preload of right heart

Answer 11

central venous pressure

Question 12

how to measure afterload of right heart

Answer 12

pulmonary vascular resistance

Question 13

what happens to mean arterial pressure in pregnancy

Answer 13

unchanged, typical is 80s
so use it! less than 65 …

Question 14

what antibiotics do you use for pyelonephritis

Question 15

what labs do you draw for sepsis?

Answer 15

CBC, CMP, lactate level, cultures

Question 16

definitiion of sepsis

Answer 16

life threatening organ dysfunction caused by dysregulated host response to infection

Question 17

septic shock

Answer 17

sepsis with persistent hypotension despite pressors or lactate > 2 despite adequate fluid

Question 18

potential risks of tocolysis when critically ill

Answer 18

pulmonary edema
hypotension
ARDS

Question 19

what is ards

Answer 19

lung injury that leads to “stiff damaged lungs that are not able to exchange air and have high pressure within them”
cant get oxygen in the blood stream
This is the PF ratio (FI O2 (putting in ) PO2 measured on blood gas.

Question 20

PF low numbers?

Answer 20

LOWER NUMBERS worse oxygen exchange

Question 21

indications for intubation/mechanical ventilation

Answer 21

failure to oxygenate (PO2)
failure to ventilate (PCO2)
unable to protect airway
unable to maintain work of breathing

Question 22

something special about ventilator use in pregnancy??

Answer 22

increase tidal volume to meet sats (because SV is increased in pregnancy)
O2 sat should be > 95

Question 23

ards management in preg

Question 24

indications for ecmo in pregnancy

Answer 24

sustained PF ratio less than 80
can’t get oxygen IN!

Question 25

ECMO indications in OB

Answer 25

hypoxemic respiratory failure despite maximum ventilation support
refractory cardiogenic shock with organ dysfunction
