The Effect Of Oxygen On The Heart Rate

In conclusion, the respiratory and cardiovascular systems are directly related in a complex manner, relying on one another to perform their physiological functions. Only together can both systems work to maintain the body’s internal balance, this is evident when physical demand is higher than normal. In order to meet this demand, the heart must pump more nutrient-rich blood around the body; however it needs oxygen to do this, in response the

Hypoxia is one of the major problems associated with this increase in altitude. This is due to the fact that the partial pressure of oxygen decreases proportionately with increases in altitude. Carbon dioxide that is continually excreted from the pulmonary blood to the alveoli along with water vaporizing in the inspired air from the respiratory surfaces dilute the oxygen in the alveoli which cause the oxygen concentration to decrease.

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

In addition a small rise in breathing rate and this is called anticipatory rise, this happens when exercising. The average reading for breaths per minute during exercise is 23-30. This shows that with more blood pumping through the body more oxygen is needed to keep the body at a sustainable rate to help our body create more energy. Our breathing rate will keep increasing until

Before the exercise the breathing decreased when I was counting how many breaths I can take in a minute. However whilst breathing, my breathing rate was not normal but it was essential for me to keep the results reliable.

The altitude that this stage could happen in is between 5000 to 11400 ft.(3) "The body generally has the ability to stave off further effects of hypoxia by increasing the rate and depth of ventilation and cardiac output ".(1) The respiration rate, blood pressure, and the heart rate can rise up in this stage.(2) the arterial oxygen saturations in this stage is between 80 and 90 percent.(1)

“The BSL Respiratory Effort Xdcr SS5LB was attached to the Biopac Systems MP36 and then was attached to the participant’s chest, underarms, and above the nipple line” [4]. Respiratory monitoring was done throughout the experiment. The subject was seated upon a Gold’s Gym 390R Cycle Trainer stationary bike. The Nonin Pulse Oximeter was used to monitor oxygen saturation levels in subjects’ blood and to measure changes

Benjamin Levine M.D. discusses the advantages of altitude training for elite athletes such as Olympians. While altitude training does not give a drastic advantage or improvement in performance, less than one second can be the difference between winning and losing in the Olympics. However, noncompetitive athletes most likely will see little to no improvement from altitude training even though gimmicky products such as “high elevation” training masks say so otherwise. Training at high altitude delivers less oxygen to the muscles, which increases the mass of red blood cells. The mass of red blood cells allows the blood to carry more oxygen; this allows the blood expanding effect to enhance an elite athlete’s performance by 1 to 2 percent.

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

In subjects who have acclimatized to altitude over a period of more than 3 weeks, exercising at the

As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

Investigating the Effect of Exercise on Pulse Rate Aim: To see what happens to the pulse rate during exercise. Prediction: I predict that the pulse rate will increase in order to take more oxygen for respiration. The heartbeat will increase and become stronger to transport oxygen and carbon dioxide to and from the muscle cells. The breathing rate will increase in order to get rid of the extra waste such as Carbon dioxide. Respiration is the release of energy.

To start off the experiment, a baseline was needed in order to be able to compare the different variables through out the experiment. The subject was instructed to sit and relax quietly while the blood pressure cuff and pulse plethysmograph were placed properly. After the blood pressure was taken and analyzed, it was found that the subject’s blood pressure was 122/64 mm Hg and a pulse rate of 60 bpm. Now that the baseline was obtained, continuing with the changing variables could take place. Starting with the variable of postural changes, the subject first reclined for three minutes. After the two minutes, the

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.
