Pressure half time is the time required for the peak pressure gradient to reduce by half (1/2) which will correspond to a decrease in peak velocity by a factor of square root of two (21/2). Pressure half time of a regurgitant jet depends on the severity of the regurgitation and the compliance of the receiving chamber.
A deceleration is a decrease in the fetal heart rate below the fetal baseline heart rate. An early deceleration is defined as a waveform with a gradual decrease and return to baseline with time from onset of the deceleration to the lowest point of the deceleration (nadir) > 30 seconds. The nadir of the early deceleration occurs with the peak of a contraction.
