giai đoạn thư giãn có độ dài hơn so với giai đoạn nén. False, cả hai nên được mịn màng và bình đẳng. T / F: nén ngón tay cái hoặc ngón tay không nên được nâng lên khỏi xương ức trong giai đoạn thư giãn. True. Khi nào bạn nên chấm dứt nén? Khi nhịp tim đạt đến 60 hoặc nhiều hơn bpm | CHAPTER 9 Newborn Resuscitation 119 o What is the depth of neonatal compression 1 3 1 2 the diameter of the chest. o What is the rate of neonatal compressions 120 times per minute. o T F The relaxation phase should be longer than the compression phase. False they should both be smooth and equal. o T F The compressing thumbs or fingers should not be lifted off the sternum during the relaxation phase. True. o When should you cease compressions When the heart rate reaches 60 or more bpm. o A rate of compressions of 120 bpm with breaths interposed at a 3 1 ratio will result in provision of how many compressions and how many breaths each minute. 90 compressions and 30 breaths each minute. o What is the most common cause of bradycardia and shock in the neonatal period Profound hypoxemia. o When should medications be administered in cases of bradycardia and shock If despite adequate ventilation with 100 oxygen and chest compressions the heart rate remains less than 60 bpm. o What is the preferred site for vascular access during neonatal resuscitation The umbilical vein because it is easily located and cannulated. o What preparation is required prior to umbilical catheterization Skin prep draped appropriately and the cord trimmed with a scalpel blade 1 cm above the skin attachment and held firmly with a ligature to prevent bleeding. o How do you identify the umbilical vein It is a thin walled single vessel. In contrast the umbilical arteries are paired have thicker walls and are often constricted. The lumen of the vein is larger than that of the arteries thus the vessel that continues to bleed after the cord is cut is usually the vein. o What size catheter should be used A F or a 5 F umbilical catheter. o How is the catheter prepared for insertion It is flushed with heparinized saline 1 U ml and attached to a three-way stopcock. 120 PALS Pediatric Advanced Life Support Review o How far should the catheter be inserted So that the tip is just below the skin and blood
