CAINZOS, R.P.; KOSCINCZUK, P.  and  FERREIRO, M.C.. Influencia de la temperatura ambiental sobre la presión arterial del perro. Rev. vet. [online]. 2014, vol.25, n.2, pp.154-157. ISSN 1669-6840.

In domestic animals the maintenance of the internal temperature within normal range is the result of the activation of many physiological responses that change vascular tone and blood pressure. The aim of this study was to evaluate arterial pressure in conscious dogs (not sedated) in an environment with temperature above 38°C and other with temperature of 24°C. For measurements of blood pressure, oscillometric method was used (vital signs monitor V6Vet®). The recorded variables were: systolic, diastolic and medium pressures (SP, DP, MP) in the right fore limb. When the temperature was above 38ºC, SP, DP and MP registered the higher means (136, 80 and 96 mmHg, respectively). When the temperature was 24ºC values were 123, 68 and 91 mmHg, respectively. Only SP registered significant difference (p<0.05). Although adverse climatic condition could affect blood pressure, SP could reflect those changes in a consistent way.
