Abstract:

COPD is the third leading cause of death worldwide. Its diagnosis can be made with spirometry, which is underused due to its limited accessibility. Portable spirometry holds promise for enhancing the efficacy of COPD diagnoses. The study aimed to estimate COPD prevalence diagnosed with a portable spirometer in high-risk patients and compare it with COPD prevalence based on data from conventional, on-site spirometry. We also evaluated the strategy of a proactive approach to identify COPD in high-risk individuals. We conducted a systematic review of original studies on COPD targeted screening an

Abstract:

After the COVID-19 pandemic, there has been an increasing demand for simple respiratory rehabilitation tools to assist patients in their recovery process. Among these tools, incentive spirometry is important in helping lung function and preventing complications such as pneumonia and atelectasis. Nevertheless, traditional spirometers are often bulky and confined to hospitals. These spirometers are not practical for home use which reduces patient safety and access to treatment. The development of a portable electronic incentive spirometer is specifically designed for patients recovering from COV

Spirometers are used globally to diagnose respiratory diseases, and most commercially available spirometers “correct” for race. “Race correction” is built into the software of spirometers. To evaluate pulmonary function and to make recordings, the operator must enter the subject's race. In fact, the Joint Working Party of the American Thoracic Society/European Respiratory Society recommends the use of race- and ethnic-specific reference values. In the United States, spirometers apply correction factors of 10–15% for individuals labeled “Black” and 4–6% for people labeled “Asian.” Thus race is

175 years have elapsed since John Hutchinson introduced the world to his version of an apparatus that had been in development for nearly two centuries, the spirometer. Though he was not the first to build a device that sought to measure breathing and quantify the impact of disease and occupation on lung function, Hutchison coined the terms spirometer and vital capacity that are still in use today, securing his place in medical history.

The high cost and limited availability of home spirometers pose a significant barrier to effective respiratory disease management and monitoring. To address this challenge, this paper introduces a novel Venturi-based spirometer designed for home use, leveraging the Bernoulli principle. The device features a 3D-printed Venturi tube that narrows to create a pressure differential, which is measured by a differential pressure sensor and converted into airflow rate. The airflow is then integrated over time to calculate parameters such as the Forced Vital Capacity (FVC) and Forced Expiratory Volume

Abstract:

Ongoing spirometry quality standards are difficult to bring into the daily routine of general practice. As a result, spirometry is rarely performed by primary care physicians. A new approach is proposed: exclusion spirometry. Acceptable and reproducible results are sought. However, the goal of the test is to try to reach values within normal limits, even if results do not reach quality standards. Normal results would be sufficient to exclude respiratory impairment, except in asthma. Abnormal results would require further testing in a diagnostic spirometry laboratory.

The aim of this case series is to show how observation of spirometric loops, similar to electrocardiogram or CO2 curve monitoring, can improve safety of anesthetic management in small animals. Spirometric monitoring cases described in this case series are based on use of the anaesthesia monitor

Abstract:

The COVID-19 pandemic necessitated an urgent reconfiguration of our difficult asthma (DA) service. We rapidly switched to virtual clinics and rolled out home spirometry based on clinical need. From March to August 2020, 110 patients with DA (68% virtually) were seen in clinic, compared with March–August 2019 when 88 patients were seen face-to-face. There was DA clinic cancellation/non-attendance (16% vs 43%; p<0.0003). In patients with home spirometers, acute hospital admissions (6 vs 26; p<0.01) from March to August 2020 were significantly lower compared with the same period in 2019. Th

Abstract:

Spirometry is a commonly performed assessment of lung function for diagnostic purposes as well as for monitoring of chronic lung diseases. The last international standardization of this technique was published in 2005. After 14 years, a group of experts from two leading scientific societies, American Thoracic Society (ATS) and European Respiratory Society (ERS), published a joint position that updated the standardization of spirometry, with an extensive criteria re-organization, including key updates such as: relative contraindications, instrumentation requirement to meet the International Org

Abstract:

The objective was to document the use of spirometry and ventilation settings in small animal anaesthesia and intensive care through a descriptive, open, online, anonymous survey. The survey was advertised on social media and via email. Participation was voluntary. The google forms platform was used. It consisted of eight sections in English: demographic information, use of spirometry in spontaneously ventilating/mechanically ventilated dogs, need for spirometry, equipment available and calibration status, ventilation modes, spirometry displays, compliance (CRS) and resistance (RRS) of the resp

Abstract:

SummaryEver since pioneering technology brought objective lung function measurement out of the laboratory with the introduction of “office spirometers” nearly 50 yrs ago, there has been a debate on whether nonspecialist practitioners can reliably achieve accurate lung function measurements. This debate continues today, because although it is certain that some users can achieve excellent-quality lung function measurements in general practice, occupational medicine and other nonspecialist practices, it is equally certain that some very poor-quality spirometry measurements are being performed.

Abstract:

Background: Methods of determining proper endotracheal tube (ETT) cuff pressure to prevent air leakage include the minimal occlusive volume (MOV) technique, which uses auscultation, and the spirometer technique, which directly measures inspiratory and expiratory breathing volumes. Spirometers may measure even small air leakage, therefore, the spirometer technique requires a higher cuff pressure than the MOV technique to completely seal the airway. This study aimed to evaluate the difference in cuff pressure between the two techniques used to seal the airway.Methods: Thirty-five female patients

Abstract:

Non-contact physiological measurements have been under investigation for many years, and among these measurements is non-contact spirometry, which could provide acute and chronic pulmonary disease monitoring and diagnosis. This work presents a feasibility study for non-contact spirometry measurements using a mobile thermal imaging system. Thermal images were acquired from 19 subjects for measuring the respiration rate and the volume of inhaled and exhaled air. A mobile application was built to measure the respiration rate and export the respiration signal to a personal computer. The mobile app
