Evaluation of the Neonatal Resuscitation Program's recommended chest compression depth using computerized tomography imaging

Proper compression landmark and depth for cardiopulmonary resuscitation in patients with pectus excavatum: a study using CT

“…When we apply the recommended compression depth according to the current guidelines (at least 5 cm, but not exceeding 6 cm), the remained IT was 3.3–4.3 cm in controls and 1.0–2.0 cm in PE patients. Some previous studies defined the remained IT of less than 10 mm as a risk depth in children for the risk of myocardial injury 12 13. The range of 1.0–2.0 cm of remained IT in PE patients would result in intrathoracic organ damage.…”

The 3:1 is superior to a 15:2 ratio in a newborn manikin model in terms of quality of chest compressions and number of ventilations

“…Thus, providers vary widely in the depth achieved during a 2-min paradigm, and some are unlikely to achieve the ‘desired one-third anterior posterior diameter depth’ 13. Moreover, significant decay occurs over time particularly with a 5:1 and 15:2 ratio and for all ratios during the last phase of compressions.…”

Part 13: Neonatal Resuscitation

“…3 Compressions are delivered on the lower third of the sternum [153][154][155][156] to a depth of approximately one third of the anteriorposterior diameter of the chest (Class IIb, LOE C-LD). 157 Two techniques have been described: compression with 2 thumbs with the fingers encircling the chest and supporting the back (the 2-thumb technique) or compression with 2 fingers with a second hand supporting the back (the 2-finger technique). Because the 2-thumb technique generates higher blood pressure and coronary perfusion pressure with less rescuer fatigue, the 2 thumb-encircling hands technique is suggested as the preferred method [158][159][160][161][162][163][164][165][166][167][168][169][170][171][172] (Class IIb, LOE C-LD).…”
