|---|---|---|---|---|---|
| UTERINE BLOOD FLOW IS AT WHAT RATE | 500 - 700 ML/MIN
🗑
|
||||
| IS UBF AUTOREGULATED | NO IT IS NOT AUTOREGULATED
🗑
|
||||
| UBF | IS DIRECTLY PROPORTIONAL TO MEAN PERFUSION PRESSURE ACCROSS THE UTERUS AND INVERSELY PROPORTIONAL TO UTERINE VASCULAR RESISTANCE
🗑
|
||||
| WHAT DOES HYPOTENSION DO TO UBF | IT DECREASES UBF
🗑
|
||||
| WHAT DOES EPIDURAL OR SPINAL ANESTHESIA DO TO UBF | IT DOES NOT ALTERED UBF IF MATERNAL HYPOTENSION IS AVOIDED.
🗑
|
||||
| WHAT DOES UTERINE VASCUCLAR RESISTANCE (UVR) DO TO UTERINE | UVR CAUSES UTERINE CONTRACTIONS AND IT DECREASE UTERINE BLOOD FLOW. IT ALSO CAUSES ENDOGENOUS RELEASE OF CATECHOLAMINES R/T MATERNAL STRESS & PAIN
🗑
|
||||
| WHAT IS ANESTHESIA CONSIDERATION | EPHEDRINE IS NOT ASSOCIATED WITH SIGNIFICANT DECREASES IN UBF
🗑
|
||||
| PLACENTAL EXCHANGE OCCURS | PRIMARILY BY DIFFUSION
🗑
|
||||
| WHAT DOES THE DIFFUSION DEPEND ON | THE DIFFUSION DEPENDS ON MATERNAL-TO-FETAL CONCENTRATION GRADIENTS, MATERNAL PROTEIN BINDING, MOLECULAR WEIGHT, LIPID SOLUBILITY, AND DEGRESS OF IONIZATION OF SPECIFIC SUBSTANCE
🗑
|
||||
| WHAT DRUGS DO NOT CROSSES THE PLANCENTA | BARBS, OPIATE, LA, DO NOT READILY CROSSES THE PLACENTA BECAUSE THEY ARE (LOW MW). NDNM AGENT ARE (HIGH MW, POORLY LIPOID SOLUBLE) AND SUCC (HIGHLY IONIZED) DON NOT READILY CROSS THE PLANCENTA
🗑
|
||||
| DUCTUS VENOSUS | SHUNTS BLOOD FROM THE UMBILICAL VEIN TO THE INFERIOR VC (BYPASSING THE LIVER)
🗑
|
||||
| FORAMEN OVALE | SHUNTS BLOOD FROM THE RA TO LA
🗑
|
||||
| DUCTUS ARTERIOSUS | SHUNTS BLOOD FROM THE PULMONARY ARTERY TO DESCENDING AORTA (BYPASSING LUNGS).
BRAIN AND UPPER BODY RECEIVE WELL OXYGENATED BLOOD
ABDOMEN AND LOWER BODY RECEIVE LESS WELL OXYGENATED BLOOD
🗑
|
||||
| HOW DOES THE FETUS GET OXYGENATED BLOOD | WELL OXYGENATED BLOOD ENTERS THE FETUS FROM THE PLANCENTA VIA THE UMBILICAL VEIN
🗑
|
||||
| HOW MANY SOURCES DOES IVC HAS | IT HAS THRESS SOURCES
🗑
|
||||
| BLOOD ENTERS THE RA FROM THE IVC; BETTER SATURATED BLOOD ENTERS THE LA VIA THE FORAMEN OVALE (SHUNT BETWEEN RIGHT AND LEFT ATRIA) (TRUE OR FALSE) | TRUE
🗑
|
||||
| FROM WHEN DOES THE BLOOD ENTER THE ASCENDING AORTA. | BLOOD ENTER THE LV AND IS EJECTED INTO THE ASCENDING AORTA
🗑
|
||||
| BLOOD RETURNS TO THE HEART VIA WHAT? | BLOOD RETURNS TO THE HEART VIA THE SVC AND COMBINES WITH BLOOD IN THE RA
🗑
|
||||
| FROM THE RA WHEN DOES THE BLOOD GOES TO | IT ENTERS THE RV AND IS EJECTED INTO THE PULMONARY ARTERY; SMALL AMOUNT GOES TO THELUNGS REMAINDER SHUNTED ACROSS THE DUCTUS ARTERIOUSUS (PULM ARTERY TO AORTA)
🗑
