We sought to establish whether an expedited or 'fast-track' NHS service to diagnose obstructive sleep apnoea (OSA) and establish vocational drivers on continuous positive airway pressure (CPAP) within 4 weeks of referral was possible. This model is recommended by the OSA Partnership Group. In total, 55 vocational drivers were referred to two sleep services. Assessment showed 73% had moderate or severe OSA on sleep study. Of those commenced on CPAP, review was a mean of 15 days after initiation (range 3-62 days)...

BACKGROUND: The purpose of the present study was to evaluate how obstructive sleep apnoea (OSA) influences left ventricular (LV) torsion and whether nasal continuous positive airway pressure (CPAP) therapy has any impact on LV torsion in OSA patients with established cardiovascular risk factors. METHODS: LV torsion was assessed by two-dimensional speckle tracking echocardiography (STE) in 162 participants without overt cardiovascular disease. The participants were categorized according to the apnoea-hypopnea index (AHI) as controls and mild, moderate and severe OSA patients...

STUDY OBJECTIVE: Continuous Positive Airway Pressure (CPAP) is considered to be the gold standard treatment for obstructive sleep apnoea (OSA). CPAP monitoring systems allow tracking of patient CPAP adherence and treatment efficacy, by measuring residual sleep-disordered breathing, hours of CPAP use, and mask leak etc. The American Thoracic Society (ATS) published a position paper in 2013 highlighting issues of interpreting CPAP data such as a lack of consistency between CPAP manufacturers data algorithms, legal implications of CPAP data and implications for CPAP adherence...

Tracking of the within-breath changes of respiratory mechanics using the forced oscillation technique may provide outcomes that characterise the dynamic behaviour of the airways during normal breathing.We measured respiratory resistance (Rrs) and reactance (Xrs) at 8 Hz in 55 chronic obstructive pulmonary disease (COPD) patients and 20 healthy controls, and evaluated Rrs and Xrs as functions of gas flow (V') and volume (V) during normal breathing cycles. In 12 COPD patients, additional measurements were made at continuous positive airway pressure (CPAP) levels of 4, 8, 14 and 20 hPa...

The care of small and sick neonates requires biomedical technologies, such as devices that can keep babies warm (radiant warmers and incubators), resuscitate (self-inflating bags), track growth (weighing scales), treat jaundice (phototherapy units) and provide oxygen or respiratory support (hoods, continuous positive airway pressure (CPAP) devices and ventilators). Until the 1990s, most of these products were procured through import at a high cost and with little maintenance support. Emerging demand and an informal collaboration of neonatologists, engineers and entrepreneurs has led to the production of good quality equipment of several high-volume categories at affordable cost in India...

Many types of positive airway pressure (PAP) devices are used to treat sleep-disordered breathing including obstructive sleep apnea, central sleep apnea, and sleep-related hypoventilation. These include continuous PAP, autoadjusting CPAP, bilevel PAP, adaptive servoventilation, and volume-assured pressure support. Noninvasive PAP has significant leak by design, which these devices adjust for in different manners. Algorithms to provide pressure, detect events, and respond to events vary greatly between the types of devices, and vary among the same category between companies and different models by the same company...

Non-invasive assessment of ventilatory control stability or loop gain (which is a key contributor in a number of sleep-related breathing disorders) has proven to be cumbersome. We present a novel multivariate autoregressive model that we hypothesize will enable us to make time-varying measurements of loop gain using nothing more than spontaneous fluctuations in ventilation and CO2. The model is adaptive to changes in the feedback control loop and therefore can account for system non-stationarities (e.g. changes in sleep state) and it is resistant to artifacts by using a signal quality measure...

PURPOSE: Noninvasive pressure support ventilation is intended to relieve the load on respiratory muscles and to prevent exhaustion. This includes continuous positive airway pressure (CPAP) as well as pressure support ventilation (PSV). Speckle tracking echocardiography (STE) allows quantification of tissue deformation by tracing characteristic grayscale patterns, independent of the acquisition angle. The aim of the present study was to assess the applicability of using STE as a way to investigate diaphragm movement using deformation analysis as a parameter for respiratory workload...

As part of a supplement entitled “Born Too Soon”, this paper focuses on care of the preterm newborn. An estimated 15 million babies are born preterm, and the survival gap between those born in high and low income countries is widening, with one million deaths a year due to direct complications of preterm birth, and around one million more where preterm birth is a risk factor, especially amongst those who are also growth restricted. Most premature babies (>80%) are between 32 and 37 weeks of gestation, and many die needlessly for lack of simple care...

BACKGROUND: Continuous positive airway pressure (CPAP) is considered the treatment of choice for obstructive sleep apnea (OSA), and studies have shown that there is a correlation between patient adherence and treatment outcomes. Newer CPAP machines can track adherence, hours of use, mask leak, and residual apnea-hypopnea index (AHI). Such data provide a strong platform to examine OSA outcomes in a chronic disease management model. However, there are no standards for capturing CPAP adherence data, scoring flow signals, or measuring mask leak, or for how clinicians should use these data...

SESSION TYPE: Sleep IIPRESENTED ON: Monday, October 22, 2012 at 04:00 PM - 05:30 PMPURPOSE: Observational data support the use of Continuous Positive Airway Pressure (CPAP) therapy to reduce cardiovascular morbidity and mortality in patients with obstructive sleep apnea. One common critique of these findings is the potential for bias from the "healthy user effect," which postulates that CPAP users may be more compliant with medical co-therapies that predispose them to improved outcomes. To examine the potential for this effect, we performed an analysis of contemporaneous CPAP and cardiovascular medication usage in patients after stroke or transient ischemic attack (TIA)...

OBJECTIVE: The impact of the use of mask continuous positive airway pressure (CPAP) on patients with acute respiratory distress in the prehospital, rural setting has not been defined. The goal was to test the use of CPAP using the Respironics WhisperFlow CPAP in patients presenting with acute respiratory distress. This was a collaborative evaluation of CPAP involving a rural EMS agency and the regional medical center. Patient outcomes including the overall rate of intubation-both in the field and in the emergency department (ED), and length of stay in the hospital and Intensive Care Unit (ICU) were tracked...
