|Blood pressure drop in humans considering the effect of ambient temperature variation due to various climatic and environmental changes is such a phenomenon which is still unexplored. By implementing the developed algorithm in the blood pressure measuring devices can improve their performance. In this study, a comparison is made between the blood pressure drop readings for both men and women considering the effect of ambient temperature change and employing various heat transfer modes. For a group of healthy individuals within the age group of 27±4 years, height ranging 170±5 cm and weight 73±5 kg (means±SD), the results presented and discussed here are for both men and women with same height 170.6 cm and weight 73 kg. According to the mathematical model created and after the implementation of the developed algorithm, it is observed that ambient temperature variation certainly affects arterial blood pressure drop in the brachial artery with length 22.22 cm. The range of systolic blood pressure drop values in case of men lies between 2.7561 mmHg to 6.5470 mmHg and the range of diastolic blood pressure drop lies between 0.3802 mmHg to 0.9032 mmHg. For women, the range of systolic blood pressure drop values lies between 2.4996 mmHg to 5.9356 mmHg and for diastolic blood pressure drop, this range lies between 0.40233 mmHg to 0.95539 mmHg. The obtained values for blood pressure drop can be added as a correction factor to the readings presented as final output by the current blood pressure measuring devices in order to obtain the correct systolic and diastolic blood pressure values. Hence, this study is termed as blood pressure drop-correction factor (BPD-CF). This analysis helps to infer about the functioning of the heart and its cardiac cycle.
