Abstract

Calibration is an activity to determine the conventional correctness of the value of measuring instrument designation and measuring material by comparing against the measuring standards that are traced to national or international standards. A sphygmomanometer is a device used to measure blood pressure. Suction pump is a tool to suck various types of fluid formed from the body's secretion process that under certain conditions need to be cleaned. DPM (Digital Pressure Meter) is a tool for calibrating sphygmomanometers and suction pumps. Therefore, it takes a calibrator device to calibrate both tools. The purpose of this study was to determine the sensor response and analyze the accuracy of the design of a dual pressure calibrator (+ and -) that can be used for two devices at once (sphygmomanometer and suction pump) using one sensor (pss-C01V-R18 autonics). The research was conducted at the Campus of the Department of Electrical Engineering Of The Ministry of Health Surabaya, first the data was taken from three different brands of sphygmomanometer and suction pump, the second data was taken using module calibrators, and the third data collection from modules and comparison tools (DPM). In this study successfully measured positive and negative pressure with autonics sensors, the results obtained are accurate in accordance with the results of standard tools. The result of this tool can be used for dual pressure calibrators using autonics sensors.

Abstract

Instruments in the hospital environment have a role to help and promote more accurate diagnosis and treatment. The general condition of the equipment used and their delivery are very important for a good prognostic. One of them is a device to measure blood pressure called a sphygmomanometer. There are 3 types of sphygmomanometer, namely digital, mercury, and aneroid. Currently, digital sphygmomanometers are known to be easy to use, but their accuracy is low and reduces the ability of nurses to identify blood pressure in humans. Mercury sphygmomanometer has high accuracy, but should not be used because it still uses mercury as a display. This is supported by the Ministry of Health's program to free the world of health from mercury because of the impact of mercury on health and the importance of nurses to train the skills of nurses. The purpose of this study was to reduce the use of mercury which is harmful to humans, in addition to training the nurse's ability to take blood pressure readings on patients. The method used by the researcher is to test the suitability value of the module with the calibrator and to collect data on six respondents to compare the module with the sphygmomanometer that has been traded. The result of the research is the error value when testing the module's suitability value with the DPM (Digital Pressure Monitor) calibrator with a range from 0 to 0.67%. each set point has a different error value. and the lowest error value is among the six set points, namely 0% and the highest error value is 0.67%. Meanwhile, the lowest error value in systole is 0.2% and the highest error value is 2.16%. While the lowest error value in diastole is 0% and the highest error value is 5.55%. Based on the results of the research that has been carried out, the authors conclude that this module is made to replace mercury which is prohibited from being used because it is dangerous for humans and trains nurses' abilities in determining blood pressure readings.

Abstract

X-ray radiation is used to diagnose the human body. Two parameters are often used as settings when using this machine. The first is the KV value, and the second is the mA value. If an error occurs in the kV setting, it will cause inappropriate image quality, so that it will provide inaccurate information in patient examination. Likewise with the presence of excessive doses to the patient's body. To ensure that the KV value that comes out is in accordance with the settings on the machine consul, invasive and non-invasive measurements can be carried out. Non-invasive is becoming an easy standard to do. Several types of equipment on the market and research results have been widely used for this non-invasive activity. The problem is that currently the existing tools still use detectors at an expensive price. The purpose of this study was to design a low-cost non-invasive x-ray KVmeter detector using an LED detector and test the ability of the detector at each point of collimation.. The method used in this study is to stump the detectors placed at 4 ends of the collimation 20 cm apart. The data is taken by doing x-ray exposure at a distance of 60 cm. The module measurements were carried out under 80 mA exposure conditions for 1 second and a collimation area of ​​20 x 20 cm. X-ray exposure settings were performed at 40kV, 50kV, 60kV, and 70kV settings. The module measurement results are compared with the x-ray machine setting values. From the comparison results, the smallest error rate on Sensor 2 is 0.83% while the highest error is on S5 of 26.43%. The results can be concluded that the LED phosphor can capture x-rays, but the detector is weak due to interference from ambient light. The results obtained from the detector itself are still less stable and linear. In future research, stability and linearity will be built using a mechanical design that reduces ambient light interference.

Abstract

PIP (Peak Inspiratory Pressure) is the highest level of pressure exerted into the lungs by the ventilator during inhalation. This PIP parameter is important for monitoring because inappropriate PIP values ​​can lead to fatal errors in patients. PIP should be kept below 20 to 25 cm H2O each time ventilation. This PIP control can be a value as well as a waveform. This waveform display is also used to validate the ventilator output. Checking the output on this ventilator is used using a ventilator tester. The purpose of this research is to get the accuracy and precision of the sensor to display the waveform and PIP value of the ventilator output. The procedure of this research is to use MPX5010GP to detect the pressure value on the ventilator and then display the value and waveform of the PIP. From this study, the results of the measurement of accuracy and precision from the MPX5010 sensor to detect PIP and display a waveform graph are said to be good. This is because the highest error value is ±6.27% at the 15 CmH20 setting. While the value of the largest standard deviation at the 15 CmH20 setting is 0.837 and the greatest uncertainty value at the 15 CmH20 setting is 0.033. Then, the largest correction value is found in the 25 CmH20 setting, which is 1.56. PIF monitoring is carried out to maximize service to patients and maximize ventilator care.
