Health and Integrative Physiology (HIP) Laboratory

The focus of the Health and Integrative Physiology (HIP) laboratory is to understand how the respiratory and cardiovascular systems interact, respond and adapt to physiological stressors such as exercise, disease, and hypoxia. The interactions between the heart, vasculature, lungs, and muscles of respiration are complex with many unanswered questions remaining. Moreover, the importance of biological sex is rarely considered when exploring the complexities of cardio-respiratory interactions. A number of ongoing research studies have been designed to blend these themes. An important aim of ongoing work is to provide significant training opportunities for highly-qualified trainees ranging from undergraduates to post doctoral fellows.

The HIP lab is located in the Chan Gunn Pavilion 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.
