How is swimming critical speed analogous to critical power?

Swimming CS (m/s) corresponds to the asymptote of the distance-time relationship, analogous to CP in cycling. D' is the finite anaerobic distance above CS. The model: Total Distance = CS × Time + D'. Used to predict performance and set training zones.

What field test is used to determine swimming CS?

Perform maximal swims of 2 or 3 different distances (e.g. 200 m and 400 m) or durations with full recovery between. Plot distance vs time; the slope of the regression line is CS and the y-intercept is D'.
