The Powerbreathe is an inspiratory muscle trainer promoted as improving inspiratory muscle strength (and consequently exercise performance) in athletes and patients with respiratory disease. No published evidence supports its efficacy.2 An advantage to training was observed when outcome was assessed by maximal static inspiratory mouth pressure (mean ...

Hyperoxygenation causes vasoconstriction and increased systemic vascular resistance. This can be good in some circumstances and bad in others. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672526/ Overall there is poor evidence for supplimental oxygen in patients with pneumonia. Cochrane found that: "Non-invasive ventilation can reduce the risk of death in ...

Breathing difficulties during sleep determined to be caused by the narrowing or closing of their airway Breathing difficulties during sleep indicates suffering of Obstructive Sleep Apnoea (OSA). Support is available in the UK from the charity called The Sleep Apnoea Trust Association (SATA) There are two types of breathing interruption characteristic of ...

Even a cursory reading of the spec indicates that this will not work. Specification Must: Defines the minimum viable product clinically acceptable by clinicians [...] RMCPAP must deliver inspired oxygen concentration in the range 35 – 80% to the patient, selectable by the user. [...] All gas connectors and hoses must comply with BS EN ISO ...

There are many diseases that can't be cured, but can be kept from being lethal by supportive interventions. At its most basic level this may simply be providing a patient with shelter, food, and water while they fight off the illness. If you've never suffered from a serious illness you may not appreciate that it can weaken you so much that you may not be ...

To partly answer my own question, after trying quite a few different potential keywords for these shields, I did find one 2014 paper Efficacy of face shields against cough aerosol droplets from a cough simulator Health care workers are exposed to potentially infectious airborne particles while providing routine care to coughing patients. However, much is ...

The RSV has evolved to impair the host immune response so that it can re-infect hosts ensuring its own survival. We have seen this in the wild already with the myxoma virus mutating to suppress host immune systems as the rabbits evolved to become more resistant. The recent finding that IgA+ memory B cell generation is impaired following experimental RSV ...

From what I can tell, yes, both oxygen and carbon dioxide gas particles will follow brownian dynamics as they move through the air on both sides of an N95 mask. And, yes, studies (on people wearing N95 masks, not on the mask itself--which more directly answers the concern) have shown that carbon dioxide does get trapped in the mask and builds-up over time. (...

You may be describing the Silverster method and perhaps of use when there's a concern about Covid-19 In the 19th century, Doctor H. R. Silvester described a method (The Silvester Method) of artificial ventilation in which the patient is laid on their back, and their arms are raised above their head to aid inhalation and then pressed against their chest to ...

There is no specific mechanism to carry nitrogen in blood, it is carried in a dissolved form unlike oxygen which uses the protein haemoglobin which is contained in red cells. Animals can not utilize atmospheric nitrogen so there is very little exchange between inhaled nitrogen and dissolved nitrogen. Any nitrogen inhaled is exhaled again as it can not be ...

Airway pressure is a lot less than what a bike pump produces during a single pump action (in the usual setting of how its used). Even though ventilators work in a similar way (cf. https://i.stack.imgur.com/PgmEZ.png), CPAP by definition needs to maintain a continuous airway pressure (CPAP = continuous positive airway pressure). The pressure to be held should ...

There actually numerous documents discussing the matter but one moderately cited paper (~300 citations) Hatchett et al. (2007) compared the responses on US cities during the 1918 influenza: Nonpharmaceutical interventions (NPIs) intended to reduce infectious contacts between persons form an integral part of plans to mitigate the impact of the next ...

You're asking for the result of a trial which hasn't been conducted yet. I suspect it's not possible to delay permanently intubation just by inspiratory muscle training given that in Italy patients were intubated for about 15 days About 15 days are necessary to achieve effective weaning from respiratory care in ICU. Indeed, the experience shows that ...

This answer is about medical terminology as widely agreed and commonly used by medical professionals. Rhinitis is a broad name of a disease or condition with inflammation of the mucosal lining in the nasal cavity (Cleveland Clinic, Malacards). Inflammation can be infectious, irritant, allergic, drug-induced, etc. (a more detailed list on American Family ...

Although not a "respiratory stimulant" in the sense of stimulating muscles of respiratory, hypoglossal nerve stimulation devices, such as INSPIRE, can stimulate your tongue to move forward when sleeping, which opens up the upper airway and allows for better breathing. The STAR trial showed that hypoglossal nerve stimulation can reduce sleep apnea ...
