The focus of the Health and Integrative Physiology (HIP) laboratory is on the interactions between the respiratory and cardiovascular systems. Work in our lab is directed at understanding the physiological basis and importance of cardio-respiratory interactions in different conditions such as exercise, disease, and hypoxia. We also perform studies in patient groups to further understand the potential therapeutic effects of exercise and physical activity.
The HIP lab is located in the Osborne Center on the campus of UBC. It is equipped with techniques and equipment necessary to study the respiratory and cardiovascular systems in humans at rest and during exercise. We use Doppler ultrasound to measure blood flow to limbs. We make continuous beat-by-beat measurements of arterial blood pressure. We have recently begun to record muscle sympathetic nerve activity. Techniques to measure ventilatory responsiveness to chemical stimuli (oxygen, carbon dioxide) are in place. Data collection/analysis hardware & software are available (PowerLab and LabView). The above methods permit simultaneous measures of blood flow, vascular resistance, autonomic activity, and the quantification of the temporal alignment between the neural, ventilatory and hemodynamic responses to physiological perturbations. In addition, standard exercise physiology equipment is housed within the lab (electronically braked cycle ergometer and open-circuit gas analysis system).
