(I will only briefly note that the expression of discomfort describes an emotional reaction that may or may not be concordant with a logical and factual analysis of the situation at hand. In this case I suspect it has something to do with the availability heuristic, where dramatic events [gushing blood] are estimated to have higher probabilities than they warrant.)
The discomfort seems to stem from a concern that the patient will deteriorate on the regular medical ward and require interventions that are not available there, prompting readmission to the ICU and incurring the risk of a missed opportunity to provide necessary care during any delays in executing the transfer. Factors that may raise that concern are marginal hemoglobin values (7-8) especially considering a baseline of almost twice that several months before, the size of the GIB and the resulting hemodynamic instability, the marginal MAPs at the time of transfer. Mitigating factors are the absence of ongoing bleeding, the inference that any marginal MAPs must be from a residual volume deficit (she does not have coincident sepsis), that the vessel was successfully clipped, and the patient is up and walking about in spite of the measured MAPs. But how are we to integrate this into an estimate of the risk that may be incurred from transfer?
