Once a patient starts losing oxygen, a doctor has not more than three minutes to prevent risk of heart failure, brain damage, and death. It is important to monitor the blood volume in the microvascular bed of tissue continuously. A non-invasive medical device means to monitor arterial oxygen saturation (SaO2) on a continuous basis is pulse oximetry is typically used. Pulse oximetry is a well-established technology based on photoplethysmography (PPG) that has become one of the most commonly used patient monitors during anesthesia and in intensive care units. Anesthesia can be defined as ‘loss of sensation’. It refers to the practice of the medications either by injection or by inhalation that block the pain feeling and other sensations, or the …show more content…
The heart rate and respiratory rate can be measured by using a few medical devices that exist in the market. One of them is capnograph. Capnograph is an expensive device that requires a significant amount of maintenance as it also requires a mask or nasal cannula, and is therefore a discomfort to the patient and is hard to use. Therefore, pulse oximeter can be said as the most appealing from both economic and patient comfort perspectives.The procedure of collecting data using pulse oximeter is kind of simple. The subject can be in upright or supine positions, then the sensor will be attached to the either subject’s finger, ear or toe.PPG signal can then be obtained the pulse oximeter. The change in volume of blood will be detected by illuminating the skin with the light from a light-emitting diode (LED) and then measuring the amount of light either transmitted or reflected to a photodiode. Each cardiac cycle will appear as a peak. The shape of the PPG waveform are different from one subject to another subject, and varies with the location and manner in which the pulse oximeter is attached. Many recent efforts using advanced signal processing algorithms to get the heart rate and respiratory rate. Variable frequency complex demodulation (VFCDM), wavelet decomposition, and auto-regression are some of the algorithms that have been used in analyzing PPG signal in order to calculate the respiratory …show more content…
The technique is called “Statistical Analysis of PPG signal in measuring the heart rate and respiratory rate”. This method of analyzing overcomes the disagreement in VFCDM since it takes multiparameters in calculating the respiratory rate and heart rate. The technique proposed can be applied to the anesthetic patients and also normal person.
Objective of this project : The aim of this study is to analyse the photoplethysmogram signal from anesthetic patient and normal person by using Statistical Analysis technique. The second objective is to determine the heart rate and respiratory rate using the three parameters extracted from the PPG signal which are Respiratory Induced Frequency Variation (RIFV), Respiratory Induced Intensity Variation (RIIV), and Respiratory Induced Amplitude Variation (RIAV).
Scope of study
Catalase Activity on Substrate Based On Gas Pressure Production Rate Name of the Class Author’s Name Date Enzymes are organic compounds which act as catalysts and speed up biological reactions in biological organisms. They are not destroyed or changed during the reaction but rather they are used over and over again to catalyze many more reactions. Their activity may be affected and altered by factors such as temperature, substrate concentration, enzyme concentration and Ph.
1. Describe the relationship between intrapulmonary pressure, atmospheric pressure, and air flow during normal inspiration and expiration, referring to Boyle’s law. - Boyles law states that as the pressure of gas increases then the volume of gas decreases. Which is how intrapulmonary and atmospheric pressure are connected to one another. Intrapulmonary pressure is lower while undergoing inspiration and higher than atmospheric pressure during the time of expiration.
Then we obtained the heart rate, which was done with a total of 3 different D.
Understanding respiratory volumes, capacities, and measurements will help me perform my job as a medical assistant because they are significant being a medical assistant. First of all, when the patient is on the bed, I will measure the respiratory rate while he/she is at relaxation. In the next, I will observe the rise and fall of the victim 's chest and count the number of respirations for one full minute. Then, I will record the current time, respiratory rate and respiratory characteristics. Spirometry is used diagnose conditions that affect breathing such as asthma, pulmonary fibrosis, and cystic fibrosis.
Temperature: 97.20F, Heart rate: 70 beats per minute, BP: 130/76 mmHg, respiration: 18breaths per minute, and Pulse oximetry: 98% on room air. Rudd reports no pain on pain assessment using PQRST pain assessment method. Rudd is looking very happy to go back home. The nurse brings the discharge paperwork, educational booklet and discharge medication reconciliation form.
In this experiment, we will focus on how exercise, in particular, affects the cardiopulmonary physiology of boys across different body mass indexes. Exercise places strenuous activity on the human body. When an individual exercise, the blood flow must level up to the demands being made on the individual’s muscles, heart, and lungs. Blood flow increases so that the blood does not clot
There are many sedation scales which will vary depending on the hospital, some include the Ramsey Sedation Scale, Motor Activity Assessment Scale, Sedation-Agitation Scale, Richmond Agitation and Sedation Scale, The Hartwig Scale, and more. These scales measure factors such as level of agitation, levels of arousability, quality of responses, and drowsiness. Technological monitoring techniques to use as support include continuous pulse oximetry and capnography, which can both be effective for unattended advancing sedation and respiratory depression, (Jarzyna et al.1,
My mode is Duo Positive Airway Pressure on the Hamilton G5. It is pressure control, a set inspiratory pressure is set to be proportional to patient inspiratory pressure. The breath sequence is intermittent mandatory ventilation (IMV). Ventilatory support is between mandatory and spontaneous breaths. The rate setting directly affects the number of mandatory breaths and the level of ventilatory support.
• During conscious sedation policies were not followed properly. It is required to have vital signs, continuous pulse ox. and ECG monitoring. This needs to be done pre and post procedure. • Post sedation procedures were not followed accurately.
In this regard, cardiovascular response to exercise occurs with changes in heart rate, cardiac output, stroke volume, peripheral vascular resistance and blood pressure/arterial pressure,
VO2 max measure the maximum volume of oxygen consumed by the body to convert energy from the food that we eat into ATP that can be used at the cellular level of the body. VO2 max is important because it measures the ability of the body to produce ATP which enables the muscle to work during exercise. In order to generate ATP during aerobic exercise, the body requires oxygen. The VO2 max is a good indicator of an individual’s of cardiorespiratory capacity and endurance exercise is a way to significantly increase this capacity. VO2 max is important to the health of an individual because it measures the ability of the cells to extract and used oxygen.
Diagnosing a patient 's illness state is always a critical phase in medication. Patients admitted in the Intensive Care Unit are vulnerable to adverse effects including in-ICU morbidities and mortality. Patients in ICU are connected to equipments like Pulse oximeter, Cardiac Monitor, Face mask, Nasogastric tube to monitor their oxygen level in blood, heart rate, blood pressure and support their breathe. They are closely monitored by Cardiothoracic nurses who records these readings from the equipments several times a day. Presently, health care researchers are more focused on developing techniques to improve the effectiveness of the treatment.

This will be done using a respirometer which will measure the rate of oxygen usage. The change in volume recorded by the respirometer pipette will be an indication of this. BACKGROUND INFORMATION
