VAP rates range from 1.2 to 8.5 per 1,000 ventilator days and are reliant on the definition used for diagnosis [6]. Risk for VAP is greatest during the first 5 days of mechanical ventilation (3 %) with the mean duration between intubation and development of VAP being 3.3 days [1], [7]. This risk declines to 2 %/day between days 5 to 10 of ventilation, and 1 %/day thereafter [1], [8].

It is calculated by adding Base Hits, Bases on Balls and Hit by Pitches, and dividing by the sum of At Bats, Bases on Balls, Hit by Pitches and Sacrifices.ases on Balls (BB) - The number of bases on balls (walks) issued by the pitcher. This does not include Intentional Bases on Balls (where the manager effectively instructs the pitcher to walk a batter for tactical reasons).
