Question

IABP waveform

Answer 1

rate of upstroke--contractility rate of downstroke--SVR exaggerated variations in size with Resp and Hypovolemia **Dicrotic notch: closure of Aortic valve

Answer 2

as the pulse travels from the arterial to the periphery increased SBP decreased DBP MAP not altered *Dicrotic notch: become less and appears later -pulse pressure widens

Answer 3

nerve damage, arterial aneurysm, retained guidewire, thrombosis, hematoma/hemorrhage, air embolism, vasospasm, skin necrosis, loss of digits, infection

Answer 4

``` measures R heart filling pressures if bigger gauge: rapid admin of fluid admin vasoactive drugs removal of air emboli pulm art cath transvenous pacing leads sample central venous blood ```

Answer 5

``` RIJ 15cm LIJ 20cm and can damage thoracic duct subclavian, fem veins **L plural higher 7 french, 20cm in length no xray confirmation in OR must aspirate from all ports...if problem consider X-ray Tip in SVC just above junction of vena cava and RA T4/T5 carina ```

Answer 6

R atrial tumor, infection at site, Contralateral pneumo

Answer 7

``` usually due to poor technique air/thromboembolism dysrhythmia hematoma carotid puncture pneumo vascular damage cardiac tamponade infection **guidewire embolism ```

Answer 8

R atrium CVP= RAP= RV preload *view of R side of heart mean RA pressure in a spont breathing pt= 1-7mmhg mech vent rises 3-5mmhg (10-12) should be measured at end-expiration 3 peaks: a c v 2 descents x y

Answer 9

``` R sided catheter used for direct assessment of: intracardiac presssures (CVP, PAP, PCWP) estimate LV filling pressures and LV function -CO, PVR, SVR -mixed venous oxygen saturation -pacing options -catheters: 7-9french 110cm length marked @ 10cm intervals 4lumens: 1st: *distal port PAP 2nd: 30cm more proximal CVP 3nd: lumen balloon 4th: wires for temp thermistor ```

Answer 10

``` LV dysfunction valvular disease Pulm HTN CAD ARF, ARDS/resp failure shock/sepsis surg procedures: cardiac, aortic, OB **who benefits? severe shock **also must need to know how to interpret data ```

Answer 11

**arrhythmias (v-fib, RBBB, complete heart block) **PA rupture catheter knotting thromboembolism air embolism pneumo pulm infarction damage to heart structures wall/valves balloon rupture

Answer 12

WPW syndrome, complete LBBB

Answer 13

``` thermodilation continuos theromdilation mixed venous oximetry-O2 consumption ultrasound pulse contour: flow trac ```

Answer 14

loss of a waves: a-fib, vent pacing giant a waves "cannon" a waves: junctional rhythms, complete HB, mirtial stenosis, diastolic disfunction, MI, vent hypertrophy lg V waves- mitral regard, acute increase in intravascular volume

Answer 15

7cardiac parameters observed: 1. ventricular wall characteristics and motion 2. disease ex thickening 3. valvue stricture and function 4. Estimation of end-diastolic and end-systolic pressures and volume 5. CO 6. blood flow characteristics 7. Intracardiac air and masses

Answer 16

``` unusual causes of Hypotension pericardial tanponade pulm edema aortic dissection myocardia ischemia valvular dysfunction ```

Answer 17

``` esophageal trauma dysrhythmisa hoarsness dysphagia *most common in awake pts* ```
