Peak and trough are methods used to establish the effectiveness of a drug. Peak is drawing the serum blood levels after the drug is administered as it distributes rapidly and reaches its peak in therapeutic range. Trough is drawing the serum blood levels right before the next dose. Trough is the lowest drug level that is needed to reach therapeutic range. If trough is > than normal, the patient is at risk for adverse effects. Therefore, the doctor should expand the time interval before ordering the next dose or decrease drug dose. In general, a trough is usually drawn one hour prior to start infusion and the peak about one hour after the infusion finished. The are times when the physician orders the trough drawn immediately prior to an infusion (ie Vancomycin).
peak then trough
It is the distance from peak to peak (or trough to trough) of a wave.
It measures the length of a wave, from peak to peak or trough to trough.
In science, the height of a peak or a trough is the maximum distance from the peak to the baseline or from the trough to the baseline. It represents the amplitude of the wave or signal at that point.
Are peak, recession,trough, and expansion
Trough. A wave has a crest as its peak, just as it has a trough as its low point or dip.
ATV the peak because the employment situation is better then at the trough
The distance between the crest and trough of a wave is the peak-to-peak amplitude of the wave.
Trough.
The lowest level of medicine in the human body is referred to as the trough. On the contrary, the highest level of medicine is called as the peak.
To determine peak and trough levels in a process, one must monitor the highest (peak) and lowest (trough) points of a cycle or pattern. This can be done by collecting data at regular intervals and tracking the high and low points over time. Analyzing peak and trough levels can help in understanding patterns, trends, and variations in the process.
The peak-to-peak amplitude is the distance from the trough to the crest. The wavelength is the distance from one crest to the next crest.
