In this experiment, the photosynthetic ETR was determined in the leaf discs exposed to air, but the respiratory rate was determined in the leaf discs submerged in solution.
We found that the respiratory rate of Japanese medaka showed a downward trend initially when exposed in the copper ions solution, afterwards fluctuated repeatly arounding the lower rate, before death, the respiratory rate rised slowly for a while.
Anesthesia of the animals prior to the injection was obtained by its immersion in a solution of benzocaine (1 mM in MeOH 1%) until the animal showed a lack of motor coordination and reduced respiratory rate.
Increasing blood pressure, heart and respiratory rate.
The respiratory rate (rate of breathing) is modified by disease.
Processing the recordings allows the researchers to detect the sounds of the pulse and respiratory rate.
What's your respiratory rate, the number of breaths per minute?
For good measure, the chart includes supposed figures for her blood pressure (76/38), respiratory rate (18), and pulse (100).
Respiratory rate monitoring.
