Changes in pulmonary function after long-duration adventure racing in adolescent athletes

The present study investigated the acute effects of a mixed-modality, long-duration adventure race on pulmonary function in adolescent athletes. Twenty male adolescents aged 14 to 17 years volunteered to participate in a wilderness adventure race of 68.5-km. Expiratory function was evaluated before, immediately after, and 24 h after race completion. Measurements included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and peak expiratory flow (PEF). Maximal inspiratory and expiratory mouth static pressures (MIP and MEP, respectively) were also measured using a portable hand-held mouth pressure meter across the same time points. The mean completion time of the race was 05:38 ± 00:20 hours. A significant post-race decrease in FVC was observed immediately after the race (-5.2%, p = 0.01). However, no significant changes were observed for FEV1, PEF and the FEV1/FVC and FEV1/PEF ratios. In addition, estimates of respiratory muscle strength (MIP and MEP) were unaffected by the race. The long-duration adventure race induced no marked reduction in expiratory pulmonary function and this response was associated with no apparent respiratory muscle fatigue. Therefore, the pulmonary system of trained adolescent athletes was sufficiently robust to sustain the mixed-modality, long-duration adventure race of ∽5-6 h.

A Digital Pressure Meter Equipped with Pressure Leak Detection

A manual sphygmomanometer is an instrument used to measure blood pressure, and consists of an inflatable cuff, a mercury manometer (or aneroid gauge) and an inflation ball and gauge. To assess the condition, accuracy and safety of mercury and anaeroid sphygmomanometers in use in general practice and to pilot a scheme for sphyg- momanometer maintenance within the district. Therefore, it must be calibrated periodically. Using the MPX 5050GP sensor as a positive pressure sensor. Requires a maximum pressure of 300 mmHg. This tool is also equipped with a SD Card as external storage. The display used in this module is TFT Nextion 2.8”. After conductings measurements of the three comparisons consisting of Multifunction, DPM and mercury tensimeter to 6 times, the smallest result 0 mmHg and the largest results 251.52 mmHg. While the error in mercury tensimeter’s of leak test to module and rigel is 0.56% and 0.404%.

Design a Low-Cost Digital Pressure Meter Equipped with Temperature and Humidity Parameters

Calibration is a technical activity which consists of determining one or more properties and characteristics of a product, process or service according to a predetermined special procedure. The purpose of calibration is to ensure measurement results comply with national and international standards. The purpose of this study is to design two mode digital pressure meter (DPM) device equipped with a thermo-hygrometer and pressure in which the design is completed with a selection mode to determine the positive and negative pressure (vacuum) using MPX 5050GP sensor as a positive pressure sensor. In this design DHT 22 sensors is used to measure the humidity and temperature. To test the leak test this device is also equipped with timer. This design uses a 2.4 inch Nextion TFT LCD screen to display data. Data analysis was performed by comparing modul with standard tools. In the measurement process, Mercury tensimeter was carried out 6 times the data and the smallest results were 0 mmHg on the module and 0 mmHg on the standard tool and the largest was 298.0 mmHg on the module and 300 mmHg on the standard tool. Data were collected in a room with a temperature of 31̊C and humidity of 87%. Finally, this design is applicable for daily used for electromedical engineer to calibrate the sphygmomanometer in the hospitals

Rancang Bangun Flow Meter Trainer Kit di Politeknik Negeri Batam

Flow Meter Trainer Kit dirancang karena keterbatasan peralatan laboratorium terkait di Politeknik Negeri Batam. Flow Meter Trainer Kit merupakan alat ukur untuk aliran fluida yang dilengkapi dengan penambahan tekanan dalam bentuk alat peraga. Secara umum, proses aliran air dimulai dengan mengisi penuh tangki air lalu pompa akan bekerja untuk mengalirkan air melalui pipa, melewati pressure meter dan rotameter yang bertugas untuk membaca hasil pengukuran debit aliran fluida sekaligus mengatur jumlah aliran fluida. Selanjutnya, air akan mengalir melewati water flow sensor dan kembali lagi ke dalam tangki. Modul praktikum akan dikembangkan berdasarkan trainer kit ini.

Efficacy of Incentive Spirometry in Expiratory Muscle Training Following Abdominal Surgery

BACKGROUND: Incentive spirometry is a device which helps in the improvement of lung function after abdominal surgery. It motivates the patients by giving visual feedback about their lung volumes. It is one of the less expensive and user-friendlydevices. Incentive spirometry facilitates the patients to take slow deep breath and there by producing a sustained maximal inspiration (SMI) that mainly helps in the prevention of atelectasis. But it is a common practice for physiotherapists to teach the patients to do expiratory exercise by reversing the incentive spirometer. The simplest way to measure the maximal inspiratory and expiratory pressures is by respiratory pressure meter in cmH2o. OBJECTIVE: To find out the efficacy of incentive spirometer in improving the expiratory muscle strength following abdominal surgery. METHODOLOGY: Quasi-Experimental study. PROCEDURE: 30 subjects were conveniently selected based on inclusion and exclusion criteria and allotted to group A (n=15) and group B (n= 15). Both groups were trained for inspiratory muscle and group A was also trained for expiratory muscle using incentive spirometry. OUTCOME MEASURES: Maximal inspiratory pressure (MIP), Maximal expiratory pressure (MEP). RESULT: This study shows that the mean MIP value have improved from 2nd to 7th postoperative day, but it is not statistically significant (P>0.05). The mean MEP values shows statistically significant (P<0.05) improvement from second to 7th postoperative day in group A when compared to group B. CONCLUSION:This study concludes that there is significant improvement in the expiratory muscle strength along with inspiratory muscle strength by training with the Incentive spirometry in the upside down and upright positions respectively.

Changes in pulmonary function after long-duration adventure racing in adolescent athletes

Objective: The present study investigated the acute effects of a mixed-modality, long-duration adventure race on pulmonary function in adolescent athletes. Methods: Twenty male adolescents aged 14 to 17 years volunteered to participate in a simulated competitive wilderness adventure race of 68.5-km. Expiratory function was evaluated by spirometry with an Ergocard CPX Clinical system before, immediately after, and 24 h after race completion. Measurements included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), forced expiratory flows at 25%, 50% and 75% of FVC (FEF25, FEF50, FEF75, respectively) and peak expiratory flow (PEF). Maximal inspiratory and expiratory mouth static pressures (MIP and MEP, respectively) were also measured using a portable hand-held mouth pressure meter across the same time points. Results: The mean completion time of the race was 05:38 ± 00:20 hours. A significant post-race decrease in FVC was observed immediately after the race (-5.2%, p < 0.05). However, no significant changes were observed for FEV1, PEF or the FEV1/FVC and FEV1/PEF ratios. The results also showed no significant modifications in the maximal expiratory flow-volume curves irrespectively of FVC percentages (FEF25, FEF50, FEF75). In addition, estimates of respiratory muscle strength (MIP and MEP) were unaffected by the race. Conclusion: The long-duration adventure race induced no substantial reduction in expiratory pulmonary function and this response was associated with no apparent respiratory muscle fatigue. Therefore, the pulmonary system of trained adolescent athletes was sufficiently robust to endure the mixed-modality, long-duration adventure race of ∼5-6 h.
