In the second thought experiment, let us consider a patient with significant blood volume loss that is replenished with a series of blood transfusions. Operating point guided resuscitation How do we make sense of this? The trick, I believe, lies in ‘operating point guided resuscitation’ [OPGR].

Four-year-old Ed is being resuscitated for presumed Invasive Group A Streptococcal Sepsis from tonsilitis. Obviously, one also needs to address the cause of the shock, or any efforts in resuscitation will only bring a temporary improvement. The amount of blood that comes from the heart with each contraction is the stroke volume (SV).

Neonatal hypotension can result from inadequate cardiac output, low systemic vascular resistance, or a combination of both, which are influenced by: Cardiac Output: Neonates, particularly preterm ones, may have compromised cardiac output due to myocardial immaturity, leading to reduced stroke volume and heart rate.
