CARDIAC

CCRN

QuestionAnswer
STROKE VOLUME/INDEX ASSESSES PUMP PERFORMANCE
CARDIAC OUTPUT ASSESSES BLOOD FLOW
CVP/ RAP ASSESSES RIGHT HEART FILLING PRESSURES
PAOP ASSESSES LEFT HEART FILLING PRESSURES
SvO2 ASSESSES TISSUE OXYGENATION.
SvO2 0.60 - 0.75
STROKE VOLUME 50 -100 mL/beat
STROKE INDEX 25 - 45 mL/beat/M2
CARDIAC OUTPUT 4 - 8 L/min
CARDIAC INDEX 2.5 - 4 L/min/M2
CVP 2 - 6 mmHg
PAP 25/10 mmHg
PAOP 8 -12 mmHg
SVR 900 - 1300 dynes sec/cm5
PVR 40 - 150 dynes sec/cm5
MAP 70 - 110 mmHg
SVRI 1900 - 2400 dynes sec/cm5
SvO2 level interpretation. < 0.60 represent a threat to tissue oxygenation. < 0.50 Threat is urgent > 0.80 may indicate oxygen is inadequate. > 0.90 ususally erroneous
SI level interpretation. < 25ml/beat/M2 indicate impaired ejection due to1. inadequate preload.2. reduced contractility, e.g. LV failure.3. increased resistance (AFTERLOAD).
CI level interpretation. < 2.2 L/min/M2 reflect threat to tissue oxygenation.- may be normal despite low SV/SI if heart rate increased.
PAOP level interpretation. - <8 mm Hg reflects possible hypovolimia if SI is low.- >12 mm Hg reflects possible LV failure if SI is low. ->25 relects threat of pulmonary congestion.
CVP level interpretation. < 2 mmHg reflects possible hypovolemia if SI is low. > 6 mmHg reflects possible RV failure if SI is low.
SVR level interpretation. < 900 dynes-sec/cm5 indicates low systemic vascular resistance. e.g. sepsis > 1300 dynes-sec/cm5 incicates high systemic vascular resistance. e.g. hypertension, compensation of low CI.
PVR level interpretation. < 40 dynes-sec/cm5 indicates low pulmonary vascular resistance. e.g. sepsis. > 150 cdynes-sec/cm5 indicates high pulmonary vascular resistance. e.g. pulmonary hypertentionprimarysecondary- chronic lung disease, ARDS, pulmonary emboli, LV failure.
Causes of low SvO2 (< 0.60). LOW CO/CI - HYPOVOLEMIA, LV FAILURE.LOW HEMOGLOBIN - BLEEDING, DISHEMOGLOBINEMIALOW SaO2 - PULMONARY DISFUNCTION.HIGH O2 CONSUMPTION - INCREASED METABOLIC RATE.
Causes of high SvO2 (> 0.80). SEPSIS, SYSTEMIC INFLAMMITORY RESPONSE SYNDROME (SIRS), CIRRHOSIS, ANATOMIC ARTERIOVENOUS SHUNT (AV FISTULA-DIALYSIS)
CORONARY SINUS It is the main venous drainage vessel of the heart.
The A wave on the CVP and PAOP tracing represents which physical event? ATRIAL CONTRACTION
The C wave on the CVP and PAOP tracing occurs due to which anatomic event? MITRAL AND TRICUSPID VALVE CLOSURE
Which hemodynamic waves are produced by the atria? A, C, and V waves
LACTATE 1-2 mmol/L
Creatine Kinase (CK) Total Value 0 - 170 IU/L
CK/MB 0 - 6 mg/ml
CK Index or Ratio 0 - 1.5%
Troponin I < 0.4 ng/mlBoarderline: .4 - 2 ng/mlElevated: > 2 ng/ml
BECK'S TRIAD CLASSICAL FINDING IN CARDIAC TAMPONADE. A. HYPOTENSION (DECREASED STROKE ) B. JUGULARVENOUS DISTENTION (IMPAIRED VENOUS RETURN TO THE RT. HEART) C. MUFFLED HEART SOUNDS (PERICARDIAL EFFUSION)
SYMPTOMS OF CARDIAC TAMPONADE. BECK'S TRIAD, DECREASE LOC, PULSUS PARADOXUS
CARDIAC CONTUSION BRUISING OF THE MYOCARDIUM RBBB VENTRICULAR ARRYTHMIAS
