Transcranial Doppler of infants suffering hypoxia-ischemia may demonstrate high diastolic flow in the early postasphyxial and hyperemic phase of the insult. This increase in diastolic flow decreases the resistive index. The use of the resistive index to quickly assess the infant at the bedside may become more important with the advent of newer neuroprotective strategies.
缺氧缺血性婴儿的经颅多普勒检查可能显示，在窒息后早期充血阶段舒张期血流增加。舒张期血流的这种增加会降低阻力指数。随着更新的神经保护策略的出现，利用阻力指数在床边快速评估婴儿可能变得更加重要。
