The experiment consisted of a BIOPAC MP3X unit that was prepared with a Respiratory Transducer plug that was placed around the chest below the armpits and above the nipples, the respiratory transducer must be slightly tight. Three electrode lead sets were placed on the subject’s right ulna artery just above the wrist, right posterior tibial artery just above the ankle bone, and left posterior tibial artery just above the ankle bone. EDA plugs were then placed on the subject’s finger tips of their index finger and third finger. The subject was then sat in a chair facing the director, with arms relaxed at the side of the body, and hands a part In lap, with legs flexed at knee and feet supported. A baseline was then recorded for the first subjects,
The contraction of the inspiratory muscles increases the volume of the thoracic cavity causing the pressure within the alveoli to decrease and air to flow into the alveoli. During resting inspiration, the diaphragm, the external intercostals and the parasternal intercostals contract to stimulate inspiration. During forced inspiration the scalene and the sternocleidomastoid muscles contract to further expand the thoracic cavity. The pectoralis minor muscles also play a minor role in forced inspiration. During quiet breathing, relaxation of these muscles causes the volume of the thoracic cavity to decrease, resulting in expiration. During a forced expiration, the compression of the chest cavity is increased by contraction of the internal intercostal muscles and various abdominal
Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays
Respiratory assessment is a significant aspect of nursing practice. According to the National Institute for Health and Care Excellence, respiratory rate is the best indicator of an ill patient and it is the first observation that will demonstrate a problem or deterioration in condition (Philip, Richardson, & Cohen, 2013). When a respiratory assessment performed effectively on a patient, it can result in upholding patient’s comfort and independence in progress of symptom management. Studies have acknowledged that in spite of the importance of the respiratory rate (RR) it is documented rarely than the other vital signs in the hospital settings (Parkes, 2011). This essay will highlight the importance of respiratory assessment and discuss why nurses
This lab experiment was conducted in a Texas Woman’s University exercise physiology lab room, on September 20, 2013. It consisted of two main participants: A trained participant (Male; 30 years old; 72 in. tall; 82.9 kg) and an untrained participant (Female; 20 years old; 65 in. tall; 75 kg). They were selected by my Prof. April Hartman to participate because they were best qualified to conduct the study in our class. Both participants were assigned to carry out the same experimental task. The Bruce Protocol (graded test) on a treadmill (mode of exercise) was used to conduct the VO2max test. The materials needed were: 1 metabolic cart (with computers); 2 mouthpieces; 1 nose clip; 1 treadmill; 1 RPE scale; 1 timer; pen; paper; and a HR monitor.
Methods: The participants of this study took part in the Step Test which is a form of cardiovascular exercise (Kusinitz and Fine 1995). The Step Test involved the individuals stepping up and down the low step platform for a consecutive three minutes.

Caring for people is my passion. My senior year of high school is when I witnessed my grandmother live on a ventilator for about a week. It awakened a new level of passion in me to care for people with cardiopulmonary problems. The Respiratory Therapy Care profession has intrigued me with how they improve the quality of life in their patients. I will enjoy working closely with patients in addition to working high tech equipment. By entering into this program and graduating out of this program I know that this will satisfy my personal goals for the next five years in many ways. The continues challenges of trying to figure out what’s wrong the heart that day or what’s wrong with the lung the next day will always keep me on my toes. It will always
The software setting is set as described in the lab manual. The stimulus intensity is initially set to 1 amps and gradually increased until a slight response is observed and recorded. The intensity is now increased by 0.2 amps with an interval of 2-3 seconds until the stair stepping response reaches saturation. Refer to the Muscle lab manual for the correct procedure to record data (*-*-*). Part 2 involved measurement and observation of the shape and strength of single muscle contractions such as latent period, contraction and relaxation. The Amp to 75% of max muscle contraction, 10 stimuli were recorded and 6 were selected to be observed and calculated (*-*-*-). Part 3 was used to measure the effects of frequency of stimulation and motor unit recruitment on the muscle contraction force. The Amp to 15% of the muscle contraction, constant stimulus recordings were taken increasing the frequency initially set to 1, then 2, and then in increments of 2 until maximum plateaued contraction was achieved. The interval of 5 seconds was required for each frequency. Part 4 measured the differences in relaxation rates of a fatigued and non-fatigued
. In the activity when Hyperventilation occurs there is not enough carbon dioxide in the blood. During hyperventilation the tidal volume is larger, which removes the carbon dioxide faster than it can replenish it. This is also called respiratory alkalosis; the renal system is able to compensate for respiratory alkalosis by increasing the partial pressure of the carbon dioxide levels and then decreasing the pH levels. In the experiment when we went from normal breathing to hyperventilation our Min Pco2 went from 40 to 25.94. Our pH then went from 7.40 to 7.58 max pH. When the hyperventilation stopped and the trace flat lined, this showed that the breathing was suspended. The body had to restore the Pco2 levels back to the normal value.
We were divided into couples and each of us had to measure both BP and TPR on a patient. We were given the choice to choose which of the two observations techniques our companion would perform. My partner, Alexandra and I, agreed based on our confidence levels that I would perform TPR and she would take the BP of the patient, whom in this case was a course colleague. Alexandra was the first to perform her observation. After taking the BP of the patient with the blood pressure cuff and sphygmomanometer, she uttered that she could her find the patient’s radial artery which according to Martini and Bartholomew (2007) is found in the wrist and is most often used for its ability to be pressed against the radius’ distal section. As a result she could not measure the patient’s BP. She thereby proposed that I retake the observation. I found the patient’s pulse, completed the BP measurement whiles Alexandra recorded down our observations on an observation chart. Afterwards, I measured the patient’s temperature with a tympanic membran...
The incentive spirometer made her feel defeated and was very discouraged with its use. She was unable to reach the target on the device. Also, she did not understand the importance of using it. I saw this as a teachable moment and intervened. I explained to her that evidence based practice tells us that any use of the incentive spirometer will be beneficial. Bavarsad, Shariatti, Eidani and Latifi conducted a research study of 40 patients with reduced exercise tolerance due to exertional dyspnea. They found that after 8 weeks (15 min/day for 6 days/week) there was a significant increase in exercise tolerance and a decrease in exertional dyspnea (Bavarsad, Shariatti, Eidani and Latifi, 2015). Moreover, the study revealed that participants using the incentive spirometer were able to walk an additional 54 meters during the six minute walk test.
