International Journal of Audiology, 1977
Since 1971 an impedance-plethysmographic method was been used to record changes in the breathing pattern of 218 high-risk infants during acoustic stimulation. The results of this technique, known as respiration audiometry, show that acoustically induced changes in the breathing pattern can be used as a hearing test for very young children.

This chapter discusses the respiratory system of giraffes. The respiratory system supplies oxygen, removes of carbon dioxide and produces the airflow needed to make sounds. Giraffes do not have the velocity of airflow through the airways to vibrate vocal cords sufficiently to generate sounds able to be heard by humans but can produce sounds able to be ...

Archives of Ophthalmology, 1984
Retinas from 14 comatose patients, who had been sustained with a respirator for one or more days before death, had selective characteristic alterations (ie, autophagy, cell swelling, and coagulation necrosis) of inner nuclear layer in a patchy pattern in posterior fundus.

Obstetrical & Gynecological Survey, 1963
SummaryIn 32 cases the oxygen and carbon dioxide content of the umbilical vessels was analysed. In 17 of these cases pH, Pco2 and non‐respiratory acid base balance was also studied. The results show that the placenta, even at the final stage of delivery, is effective as regards O2 and CO2 diffusion.
