Aseptic Technique Protocol

A set of standardized, sequential procedures (e.g., handwashing, gowning, draping) designed to prevent the introduction of pathogens into the surgical wound site.

The statement of the theorem

Model the surgical environment as a state space S\mathcal{S}. Let Si\mathbf{S}_i be the state after step ii (e.g., handwashing, draping). The transition from Si−1\mathbf{S}_{i-1} to Si\mathbf{S}_i is governed by a contamination reduction factor ρi≜[0,1]\rho_i \triangleq [0, 1], where ρi\rho_i is the probability that the pathogen load LL remains below the critical threshold LcritL_{crit} after step ii. The overall safety state Sfinal\mathbf{S}_{final} is achieved when the cumulative reduction factor Π=∏i=1Nρi\Pi = \prod_{i=1}^{N} \rho_i ensures Lfinal<LcritL_{final} < L_{crit}.
