Abstract

The aim of this study was to evaluate the use of whole-body plethysmography as a non-invasive method to determine the respiratory parameters and profiles in two tortoise species belonging to the genus Testudo. Pulmonary functions and volumetric parameters were determined in 10 adults of Testudo hermanni and in seven Testudo marginata animals, using whole-body plethysmography. A profile pattern was regularly observed: an inspiratory flow peak, an expiratory peak, an apnoea phase and a second expiratory peak, previous to the beginning of the next respiratory cycle. Positive and significant correlation was observed between the inspiratory time, weight and length of the tortoises. Larger tortoises showed a higher time of inhalation. The peak of inspiratory flow was correlated with the sex, being longer in the females. T. marginata had an inspiratory time longer than that of T. hermanii. In T. hermanii, differences related to the sex were observed in the tidal volume, peak inspiratory flow, peak expiratory flow, expiratory flow of 50 per cent and enhanced pause, which could be related to the smaller size of males. The results suggest that additional information on new technologies currently used in pet medicine or even in human medicine should be developed and adjusted as alternative ways to support the rehabilitation of turtles and tortoises.

摘要

本研究旨在评估体描法作为一种非侵入性方法,用于确定属于 Testudo 属的两种龟类的呼吸参数和特征。使用体描法测定了 10 只成年 Hermann 龟和 7 只 Testudo marginata 龟的肺功能和容积参数。观察到一种规律的模式:吸气峰、呼气峰、呼吸暂停期和下一个呼吸周期开始前的第二个呼气峰。吸气时间、体重和龟的长度之间存在正相关和显著相关性。较大的龟吸入时间更长。吸气流量峰值与性别相关,雌性的吸气时间更长。Testudo marginata 的吸气时间长于 Testudo hermanni。在 Testudo hermanni 中,观察到与性别相关的潮气量、吸气峰流量、呼气峰流量、50%呼气流量和增强性暂停的差异,这可能与雄性体型较小有关。结果表明,应该开发新的技术,并调整其作为支持海龟和陆龟康复的替代方法的信息,这些新技术目前在宠物医学甚至人类医学中得到应用。
