The schematic representation of the prototype is depicted in Figure 3. A Force sensing resistor (FSR) is used for measuring the applied pressure. FSR, known for its smaller size and low power consumption can be easily embedded into the system. The controller, to which the FSR is interfaced with, is Arduino®, an open source platform available for electronics prototyping for creating interactive environments [18].
Figure 3. Block diagram of the prototype. The FSR is connected through the voltage divider circuit. The pressure display unit consists of Liquid Crystal Display (LCD) that is connected to the digital ports of Arduino®. The pressure ranges are classified using the data obtained from the calibration procedure and displayed on the LCD. An alarm circuit is connected in parallel with the LCD and the buzzer goes off when the pressure exceeds the required level. The number of compressions per minute is provided by Light Emitting Diode (LED) indications. Different counts

With reference to this pressure, the pressure ranges are categorized and programmed using Arduino®. The prompts on the LCD are displayed according to the force sensed by the sensor. A visual feedback is given that provides the trainee, the necessary instructions during the procedure. Figure 9A shows the LCD outputs of different pressure levels and their corresponding ranges. A buzzer connected to pin 9 of Arduino® monitors the pressure level when the program starts running, and when the pressure level exceeds the required level, the buzzer goes off. Figure 9B depicts the alarm unit. The output from the serial monitor of Arduino® is shown in Figure 9C. The combined rate of compressions and ventilation can be in the ratio 3:1 and this would provide 90 compressions and 30 breaths per minute [7]. Figure 9D shows the visual indication to keep track of the number of compressions given per
While auscultating sounds of lung fields no wheezing was found, and VS were within normal range for patient as determined through comparison of chartings on 10/23/2015 thru the morning and lunch VS of 10/26/ 2015 before impaired gas exchange was detected. 10/26/2015 2. Administer O2 @ 2L N/C
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.
It would decrease the number by one for any interval, where there is an observed decrease in the depth of breathing. If the depth of breathing doesn’t change significantly from one interval to the next, then repeat the same number had for the previous interval. Repeat this whole process, but with a second observer doing the pre-lab activity. Afterwards, compare the results for the two observe, by checking the criteria used, and attempt to agree on reliable procedures for rating the depth of breathing. Next, switch roles to have a new subject and a timer and two new observers of depth of breathing.
Teach the patient to that the exhaling of air is twice the length of time compared to
Then that selected range is converted from analog to digital samples. The DSP processor has a definite program according to different modes selected from the switch. There are 3 modes with which we can use this device. E. Simulation: 1. Mode 1: Stress removal
When compliance decreases (stiff lungs), the rate increases, and the tidal volume decreases. Always compare the patient’s data with the machine’s data. The pressure support needed is based on the patient’s condition. When the patient gets stronger the pressure support can be dialed down and vice versa. If the respiratory rate is going high and the tidal volume is coming down patient is becoming tired and in need of more pressure support.
A kymograph is a device used for recording variations in pressure such as in sound waves, blood pressure and etc. by the trace
The potential space between the instinctive and parietal pleurae is known as the intrapleural space. The intrapleural and intrapulmonary pressures fluctuate amid ventilation. The intrapulmonary pressure is subatmospheric amid inspiration and more prominent than the atmospheric pressure amid expiration. Pressure changes in the lungs are delivered by varieties in lung volume, as per the opposite relationship between the volume and pressure of a gas portrayed by Boyle's law. The mechanics of ventilation are affected by the physical properties of the lungs.
5. Pressing the heart massage to massage the rhythm. In the speed 100 times / minute, if less than this will not work. I hope that this how to do CPR. will be benefit with you or someoneyou help.
Ventilation of a person through various activities Camila Gonzalez. This lab was made with the aim of proof that making different activities can alternate the ventilation rate, also is to see the variation of work our respiration system makes. We can see the different things and situations that can affect the normal process of ventilation and respiration, like the weather and the clothes that were limitations for doing this experiment because first the weather was so hot, so the person get tired early and began to ventilate faster and second the clothes wasn't appropriate for making the activities, because they also make weight and makes that the person get more tired. We use more than one person to make a comparison of the ventilation
So you may have obstructive sleep apnea (OSA)? What to Expect during your sleep study: Your Sleep Study and the disorders it may diagnose: Nocturnal Polysomnogram, NPSG – This is the standard overnight diagnostic sleep study. It is used to assess certain sleep disorders, including sleep apnea, periodic limb movement disorders, insomnia, and 24 hour sleep-wake cycle disruptions.
Introduction This essay will reflect on my personal experience, skills, and knowledge gained from my studies and practice of undertaking blood pressure (Bp) whilst completing my professional placement. Bp may be defined as a force of blood against vessel walls in the body, consisting of systolic and diastolic pressure measured in millimeters of mercury. (Waugh and Grant, 2016) Systolic pressure occurs when the hearts left ventricle contracts and forces blood into the aorta causing a heightened atrial pressure, while diastolic pressure refers to complete cardiac diastole, this is when the aortic valve closes and pressure is at its lowest between beats, blood moves into smaller corresponding vessels and the heart rests.
2.1(a)): as the gray accelerometer box moves from side to side, the mass (which is a red blob) is left behind and the spring connecting it to the box (red zigzag) soon pulls it back into the position and, as it moves, it draws a trace (blue line) on the paper. Fig.2.1 (b) Capacitive Accelerometer Alternative designs of accelerometers measure force not by making a pen trace on paper but by generating electrical or magnetic signals. Capacitors can be used in accelerometers to measure force in a similar way as that of mechanical ones: if a moving mass alters the distance between two metal plates, measuring the change in their capacitance gives a measurement of the force that’s acting on it. The broad concept of capacitor based accelerometer can be understood from the above figure (Fig.2.1 (b)). In some accelerometers piezoelectric crystals such as quartz do the clever work.
3. A typical respirometer was set up as follows: • A vial fitted with a stopper with a hole was taken. • A pipette was taken and inserted through the stopper so that it’s wide end is in the vial. • A wad of cotton soaked in 15% KOH is placed in the vial.
