“…The patient gradually and maximally inhales via the tube, creating a vacuum in the device chamber and levitating the spheres or piston. Flow-based and volume-based ISy devices are available for respiratory therapy, using either flow-rate calibrated levitation of a sequence of spheres or a graduated scale to report deflection of a piston and the volume of air inspired respectively [55].…”

Background: Clinically valid and reliable simulated inspiratory sounds were required for the development and evaluation of a new therapeutic respiratory exergame application (i.e., QUT Inspire). This smartphone application virtualises incentive spirometry, a longstanding respiratory therapy technique. Objectives: Inspiratory flows were simulated using a 3 litre calibration syringe and validated using clinical reference devices. Syringe flow nozzles of decreasing diameter were applied to model the influence of mouth shape on audible sound levels generated. Methods: A library of calibrated audio inspiratory sounds was created to determine the reliability and range of inspiratory sound detection at increasing distances separating the sound source and smartphones running the app. Results: Simulated inspiratory sounds were reliably detected by the new application at higher air inflows (high, medium), using smaller mouth diameters (<25 mm) and where smartphones were held proximal (< = 5 cm) to the mouth (or at distances up to 50 cm for higher airflows). Performance was comparable for popular smartphone types and using different phone orientations (i.e., held horizontally, at 45° or 90°). Conclusions: These observations inform future application refinements, including prompts to reduce mouth diameter, increase inspiratory flow and maintain proximity to the phone to optimise sound detection. This library of calibrated inspiratory sounds offers reproducible non-human reference data suitable for development, evaluation and regression testing of a therapeutic respiratory exergame application for smartphones.

“…En caso de ser necesario un feedback para el paciente, se pueden usar incentivadores que incluso facilitarán la realización de estos ejercicios por el propio paciente en su domicilio. La literatura actual recomienda el uso de los incentivadores volumétricos por encima de los de flujo porque con estos últimos el gasto energético es mucho mayor, se recluta principalmente musculatura accesoria inspiratoria, no se consigue una buena activación diafragmática y, además, un flujo rápido no ayuda a distribuir el aire en la periferia [46][47][48] . Los ejercicios a débito inspiratorio controlado, más comúnmente conocidos como EDIC, también serían de gran utilidad; se basan en conseguir una reexpansión pulmonar mediante el uso de inspiraciones lentas, apneas teleinspiratorias y espiraciones profundas 49 .…”

Resumen La aparición de la COVID-19 ha supuesto un problema de salud pública mundial, provocando una elevada presión en los sistemas sanitarios. Las secuelas de esta enfermedad han puesto de manifiesto la importancia de la rehabilitación en pacientes COVID persistente, implicando en el proceso a diferentes profesionales. El tratamiento de las secuelas respiratorias en fase ambulatoria de esta reciente enfermedad es un campo especializado y parece oportuno ofrecer una serie de recomendaciones prácticas de rehabilitación cardio-respiratoria que ayuden a todos los profesionales implicados en la tarea de tratar este tipo de secuelas una vez superada la fase hospitalaria. Esta revisión de la literatura ofrece diez aspectos clave de fisioterapia respiratoria que incluyen la valoración, los parámetros que se deben monitorizar y los signos de alerta, así como las técnicas respiratorias específicas y otros ejercicios prácticos que se deben realizar en esta población.

“…While early ISy devices coupled a breathing hose to an enclosed mechanical piston levitated by means of a vacuum created with purposeful inspiration (figure 1A), later ISy incarnations employed flow meter with LED displays (figure 1B) and more recently encased plastic spheres (figure 1C) or pistons to display and motivate inspiratory effort 5–8 14 15. Contemporary flow-based ISy devices levitate spheres at calibrated inspiratory flow rates (IFR) while volume-based ISy devices deflect a piston to indicate inspired volume 16.…”

Virtual respiratory therapy delivered through a smartphone app: a mixed-methods randomised usability study

et al. 2022

IntroductionA new smartphone app (QUT Inspire) has been developed to detect inspiratory sound and deliver virtual incentive spirometry (ISy), a respiratory therapy technique used in postoperative recuperation, management of some chronic conditions and with potential applications in SARS-CoV-2 rehabilitation. The aim of this study was to compare the usability of this new app with a clinical ISy device as measured by effectiveness, efficiency and satisfaction.MethodsIn this mixed-methods randomised usability study, healthy volunteers (aged 39.2±12.2 years, n=24) compared inspirations using the QUT Inspire app and a Triflo II clinical ISy device. A post-test questionnaire and a semi-structured interview explored dimensions of usability regarding the new app.ResultsThe duration of inspirations performed using the QUT Inspire app (7.3±2.0 s) were comparable with use of the Triflo II ISy device (7.5±2.3 s). No artefacts arising from the order of device testing were identified. App users held their phones adjacent but not proximal to their mouths (13.6±6.4 cm), notwithstanding instructions to keep the phone less than 5 cm away for optimal breath sound detection. The use of onscreen text or video instructional materials did not result in a significant reduction in this distance. Participants reported clear preferences for the app (100%, n=24) to motivate persistence with repeated inspirations. App gamification features such as a timer (75%, n=18) and breath counter (83.3%, n=20) were well regarded. Analysis of semi-structured interviews identified four main themes arising from this study: visual reward from responsive app animations, clinical look and feel influencing credibility, perceived effort affecting engagement and selective adoption of gamification features.ConclusionThis study demonstrates that a virtual ISy app can be effective, efficient and have high satisfaction. Improvements informed by this research include use of additional phone sensors to optimise sound detection and minimising the distance that phones are held from the user’s mouth. Further research in randomised controlled trials are needed to evaluate performance of this app in clinical contexts where ISy is currently employed.

Comparison of Flow and Volume Incentive Spirometry on Pulmonary Function and Exercise Tolerance in Open Abdominal Surgery: A Randomized Clinical Trial

Abstract: Flow and volume incentive spirometry can be safely recommended to patients undergoing open abdominal surgery as there have been no adverse events recorded. Also, these led to a demonstrable improvement in pulmonary function and exercise tolerance.
