Investigating Factors that Affect Heart Rate and Blood Pressure

Research factors influencing heart rate and blood pressure The pumped blood is constantly under pressure. This pressure is highest in the artery closest to the heart, and gradually decreases as blood moves around the body. Depending on the pressure difference in the blood vessel, blood moves around the body. Blood flows from the high pressure zone to the low pressure zone until it finally returns to the heart. Blood pressure is controlled by three factors: heart rate, stroke volume, and peripheral resistance.

In our experiment designed and implemented in the classroom, I wanted to examine various factors that affect blood pressure. I asked the question "Does hydration affect personal blood pressure and heart rate?" Then we made a verifiable hypothesis that consumption of water increases blood pressure and heart rate. I started experimenting by choosing two variables (dependency and independence). The independent variable ingested 16 ounces of water to moisturize the individual; the dependent variable is the measured heart rate and blood pressure. We also specified an experimental repeat group. There were 26 people in the experimental group. The overall experimental components were two groups. When blood pressure and heart rate are measured through experiments, they are measured by individual partners. We obtained 3 basal / resting BP measurements

In cardiovascular labs, students observe how physical activity affects blood pressure and heart rate. Together with the partner, the stress of the student lies down and is recorded at the basic (normal) rate after exercise. Normal blood pressure is systolic blood pressure 120, diastolic blood pressure 80. The normal heart rate is 60 heartbeats per minute. Systolic blood pressure is the contracting blood pressure and is considered to be the first convulsion of the stethoscope. Diastolic blood pressure is the intravascular pressure between heart beats at the relaxation point, the last convulsion before the needle completely falls into the stethoscope.

Measurement of Blood Pressure and Heart Rate Omron M2 Classic's brachial blood pressure monitor is used to measure blood pressure (systolic and diastolic). The pressure measured in millimeters of mercury (mmHg) and heart rate (HR) and heart rate (bpm) measured before and after the presence of a cat in the left upper arm. This is a non-invasive technique and fully automated. Participants Participants in this study (over 18 years old) were recruited in Cornwall. The cat's owner (n = 20) who agreed to participate filled in the pet scale Lexington (LAPS, Appendix 1) to judge the attachment to the cat. Owner samples include people aged 18 to 64 (average = 34.58, average = 3.39).
