Using A Handheld Portable Gas Detector Weighting Up

The purpose of this experiment was to investigate the effects of different masses hoisted by an electric motor from ground level to a height of 1.29 m. The main purpose was to look how a change in mass affected the efficiency of our motor, but it did affect other variables such as power, current, force, etc. For this experiment, our hypnosis is that as mass increases, the efficiency increases. Because in the equation for efficiency, efficiency=gain in potential differenceelectrical energy used, gain in potential difference = mgh, the mass of an object has a direct relationship with the efficiency of the motor. In this equation, we see that efficiency is affected by the mass that is lifted, gravity, the height the mass is being lifted, and the amount of energy that is put into the system. We can see that mass, gravity, and height has a direct relationship while inputted power has an inverse relationship with efficiency.

How many people workout with or without a personal trainer and don’t get as much results? May be one simple thing an athlete can add to workout routine makes the process more effective, easier, and safer. Many Athletes are committed to workout or do certain type of exercise without measuring the heart rate, which sadly and unfortunately cause them not to reach the desired goal; however, Polar Ft60 would be the best, and most efficient heart rate monitor to equip at the gym.

The objective of the lab was to purify compounds that can be turned into gas at a reasonable temperature without using decomposition. Gas chromatography was also used to identify the proportions of the volatile compound in the different samples. The mixture of hexane and octane was assigned to me and my partner. The apparatus for simple distillation was assemble using a thermocouple, air condenser, distillation head, metal keck clamps, and a conical reaction vial. The joints of the glassware were greased before assembly. Four boiling chips were placed in the conical ration vial before it was assembled. After being assigned a mixture, 3.5 mL of the mixture was put into a reaction vial. The apparatus

In conclusion, therapists should always look at the patients limitations before assessing an intervention. Therapists who are not paying attention to these precautions can cause the patient negative health conditions. So, during therapy patients with pacemakers should be limited to excessive heavy weight activities. Due to all of the precautions, patients should perform lightweight activities and avoid using modalities in therapy that has electrical current

This retrospective analysis is on a class III medical device called the Micra Transcatheter Pacing System (TPS). The device is created by Medtronic Incorporated which is a company that focuses primarily on devices for cardio and vascular, restorative therapies, diabetes, and minimally invasive therapies. The target customers are those who have slow or irregular heartbeats that need to be monitored. This pacemaker is useful for patients who could have difficulties with the placement of traditional pacemakers, or would be better off with a single chamber pacemaker. The underlying technology used is a 1in long pacemaker that is placed directly into the right ventricle through the femoral artery using

My knowledge in this area is reflected with my understanding in the concept of remotely monitoring patients is not new but recently a lot of attention has been placed on smart wearable body sensors (SWS). Therefore, these devices contain an assortment of different sensors which can be used to monitor variables and transmit data either to a personal device or to a storage site. The variety of the sensors can be attributed to the types of stimuli that they respond to, for an example, physiological vital signs, body movements, and organic substances and their placements clothing, subcutaneous implant, body part accessory, and many more. These devices have the opportunity to meet the patients’ needs by administering information in real-time to the patient’s smartphone, computer or other wireless devices and has the potential to influence their behaviours. The sensors allow patients to self-monitor, track, and assess human physiological data, while also providing interfaces and a dashboard for healthcare providers. These sensors are easily managed and are becoming increasingly accurate and reliable for patient care. The SWS’s can also be utilized as a diagnostic tool to

Monitor fatigue has been an issue ever since the technology to monitor patients was developed. The problem has gotten worse as technology has advanced and the number of alarms in the hospital increased. The average ICU has “over 40 different alarms” (Sendelbach & Jepsen, 2013). Monitor fatigue is related to any type of monitoring device used in the hospital making the scope of the problem rather large as monitors range from bed alarms to telemetry monitors. In June 2013 the Joint Commission approved new “National Patient Safety Goal NPSG.06.01.01 in clinical alarm safety for hospitals and critical access hospitals (The Joint Commission, 2013, p. 1).” One of the first goals of the hospital was to identify the alarms most at risk for

This could potentially impact society more than ever. There is a trend to start creating pacemaker devices smaller and more natural than ever before (Geselowitz). In fact, the world's smallest pacemaker is safe and effective in patients with a slow heart rhythm, according to the first human clinical trial of the device. This device is 93 percent smaller than the traditional pacemaker device. It also reduces complications and risks because it does not use leads or require a chest pocket (World’s). “This groundbreaking technology represents a significant advance in the field of permanent pacing and will improve patient care," says Dr. Nicholas Skipitaris, director of cardiac electrophysiology at Lenox Hill Hospital in New York City. Technological advances are also allowing pacemakers to become solar powered, and also double as a device that can detect, store, and report continuous heart activity. A team of Swiss researchers calculated that a 3.6-square-centimeter solar cell produces enough energy to power devices such as pacemakers. The lead author of the study, Lukas Bereuter of Bern University Hospital, hopes that wearing a solar patch beneath the skin could one day save patients from having to undergo repetitive surgeries to replace batteries, procedures that are costly and carry the risk of medical complications (Future). The

Each one of these devices serves a specific purpose to assist its allotted area of the body. We list a sampling of these devices in the following information:

Distractions and interruptions consist of anything that disrupts an individual from the current task by diverting one's attention. The advancement in technology has greatly contributed to the increase in the number of distractors in our environment. Most of the technological devices have become part of us since we need them for connectivity, comfort and work. In the Health care industry, many medical devices have alarm systems. Examples include: bedside physiologic monitors such as ECG (electrocardiogram) machines, pulse oximetry devices, and monitors of blood pressure and other parameters; infusion pumps; and ventilators. These alarm-equipped devices are very essential in enhancing and providing safe care to patients. However, these devices

The pacemaker was chosen as one of the top 5 most significant Canadian Engineering accomplishments by the “National Engineering week” in

As knowledge of the human body expanded a range of electrotherapeutic experimentations were conducted by pioneering scientists and physicians. Methods utilized both direct current and static electricity. It became clear that the heart was an organ especially sensitive to electricity as well and as early as 1788, attempts were made to treat irregular heartbeats with an electric shock. By 1932, a primitive form of today 's pacemaker was invented as a hand-cranked device by Albert Hyman (Engineering and Technology History Wiki, 2015). Hyman’s pacemaker was powered by a hand-wound spring-driven generator that provided six minutes of pace making without rewinding (Haddad, Houben and Serdijin, 2006). Today’s pacemaker weighs about 28 grams and is approximately the size of an Australian 50 cent piece (Medtronic n.d.).

There has been several improvements done with cardiac pacemakers. One of the highlight was the nanostim leadless pacemaker. It is very small in size and is implanted inside the heart through a catheter. The small size and the lack of surgical pocket with leadless device will help the patient feel better and eliminates the worry of infections and lead failure. It is designed in such a way that it is completely retrievable so that during an implant procedure it can be repositioned easily. Implanting this device will help in the recovery time of the patients because the procedure is faster and since the surgery is minimally invasive it leaves less room for error and better comfort to the patients. Another innovation the researchers are working

The battery generates power for the pacing system. It produces electricity as a result of a chemical reaction. In its simplest form a battery consists of an anode, electrolyte, separator and cathode. Pacemaker batteries are composed of Lithium Iodine. Lithium acts as an anode and provides electrons and the Iodine acts as a cathode, receiving electrons. The anode and cathode are separated by electrolytes which serves as a conductor of ionic movement but as a barrier to electron transfers (Butler, n.d). The battery voltage depends on the chemical composition of the Lithium Iodine. At the Beginning of Life (BOL) of the battery produces around 2.8 volts. At the Elective Replacement Indicator point in which 90% of battery life has been used the battery generates at around 2.4 volts. This rate decreases exponentially until the End of Life (EOL) is reached and the battery generates around 1.8 volts. The contributing factors to the longevity of the pacemaker include chemical composition of the battery, the size of the battery, the amount of internal discharge, voltage

An innovative solution to combat this issue is to have real-time monitoring for athletes deemed high risk. This may be done by creating a synthetic shirt, which is currently worn by many athletes during activity already, that has three EKG leads and a telemetry unit built in the material. It would be imperative to have the leads, wires, and telemetry streamlined to reduce bulkiness, especially since the device would be worn under pads in sports like football and hockey.
