Systems, assemblies, and methods of trauma management

A method for extracorporeal blood treatment of recovered blood, the method comprising:

• receiving an indication of a patient state including the patient having lost greater than a first specified threshold value of blood from a body cavity;
• drawing, upon receiving the indication, a first portion of the recovered blood from a body cavity of a subject and into a reservoir via a first fluid inlet, the reservoir fluidly sealed relative to an external ambient environment and configured to maintain a negative internal pressure relative to the external ambient environment;
• regulating a flow rate of at least the first portion of the recovered blood at a greater rate than a second specified threshold value, received from the first fluid inlet or the reservoir, via an inline pump fluidly coupled to an outlet of the reservoir;
• monitoring an indication of blood state over time, the indication of blood state including an indication of blood lactate concentration of at least the first portion of the recovered blood received via at least the first fluid inlet;
• and
• conditioning the recovered blood including removing lactate, the conditioning including at least one of reoxygenating hemoglobin (Hb) included in the recovered blood or selectively controlling a temperature of the recovered blood, before at least intravenous delivery back to the subject via at least a first fluid outlet;
• and
• delivering the conditioned, recovered blood back to the subject at least intravenously.
