The influence of breathing various concentrations of carbon dioxide and oxygen upon minute volume, tidal volume, and respiratory rate were examined in acetylpromazine-tranquilized horses. Responses in the horses before (control period) and after tranquilization were qualitatively similar to increases in carbon dioxide and to alterations in oxygen. The quantitative responses to these changes were less in tranquilized horses than in the same horses studied in the untranquilized state. Tranquilization had its most prominent effect upon respiratory rate in horses breathing room air.
在乙酰丙嗪镇静的马匹中，研究了呼吸不同浓度的二氧化碳和氧气对每分通气量、潮气量和呼吸频率的影响。在镇静前（对照期）和镇静后，马匹对二氧化碳增加和氧气变化的反应在性质上相似。与未镇静状态下的同一匹马相比，镇静后的马匹对这些变化的定量反应较小。在呼吸室内空气的马匹中，镇静对呼吸频率的影响最为显著。
