NPB101L Exercise 4: Human Cardiovascular System (Flipping and dunking) Pre-experiment handout Objectives: 1. To investigate the cardio and vascular responses to Exercise Postural changes Cold water face-immersion 2. To familiarize yourself with detection techniques such as sphygmomanometer and ECG Lead Type 2 cardiogram. The above two objectives will be investigated through six experiments : Sphygmanometry (Blood pressure cuff) Posture change and blood pressure, ECG (abrupt change from supine to vertical position, using a tilt table) Reactive hyperemia after arm occlusion Finding valves in veins Venous capacitance (measure arm diameter changes post venous occlusion) ECG at different levels of strenuous exercise (bike machine) ECG and diving reflex (stick your face in icy water) Buzzwords: Electrocardiogram (ECG) {P-wave, QRS complex, T-wave}, systole, diastole, cardiac output (CO), stroke volume (SV), TPR (Total peripheral resistance), vasodilation, dive-reflex, MAP, baroreceptor. (In other words, this lab focuses more on systemic properties of the cardiovascular system than how a heart pacemaker
