Re: Reservoir bag in the CPAP circuit.
Morning SP,
I have never seen a bag like that for cpap, but I can tell you what we used bladder tanks for.
It was used to smooth out pulsations in our feed flow. I'm pretty sure that is what this may be used for, not 100 % sure though. Others will be along shortly that may actually know...Have a nice day.

Re: Reservoir bag in the CPAP circuit.
every picture i can find of that in use is part of anesthesia machines.

Re: Reservoir bag in the CPAP circuit.
The purpose is to deliver a high volume of oxygen consistently. An oxygen line is attached to the bag. The bag has a one-way valve where it is connected to the CPAP hose. The one-way valve allows oxygen to enter the circuit but prevents expiratory air from entering the bag.spiropulsator wrote: ↑Fri Oct 05, 2018 4:04 amWhat is the meaning of the reservoir bag used sometimes in the CPAP circuit?

Re: Reservoir bag in the CPAP circuit.
Unfortunately, the article has little, if anything, to do with the question.
A few days ago my advice was requested in the Division of General Surgery. A seventy year old patient, who had undergone total gastrectomy three days before, "had difficulty breathing". I saw a moderately dyspnoic person, with a respiratory rate of 42 acts per minute, breathing was superficial, saturation (with mask oxygen therapy) was 85%. Arterial blood gas analysis that confirmed hypoxemia (PaO2 48 mmHg) with a PaCO2 of 42 mmHg and a pH of 7.37. There were no other relevant organ dysfunctions. Leucocytosis was present (WBC 22000 / mm3) and the chest radiograph showed bilateral thickening and basal effusions.
We admitted the patient in Intensive Care for postoperative respiratory failure secondary to pneumonia. Now it is intubated and ventilated. Tracheotomy is likely in the next few days.
A case like many. But really inevitable?
In some cases we have effective weapons to reduce the likelihood of postoperative respiratory complications in patients undergoing major abdominal surgery. One of these is the use of CPAP in the postoperative period in patients who exhibit moderate hypoxemia.
An Italian clinical trial compared non-invasive CPAP (7.5 cmH2O) vs. oxygen therapy in patients who had a PaO2 / FIO2 <300 mmHg at one hour after extubation. L ' postoperative intubation was required in 1% of patients who undergo CPAP and in 10% of patients with oxygen. Even pneumonia postoperative were reduced by the use of CPAP (CPAP 3% vs. 10% with oxygen).
The effectiveness of postoperative CPAP in reducing postoperative respiratory complications in patients undergoing addugal surgery is also confirmed by a meta-analysis ( 2 ). The risk of developing postoperative respiratory complications is reduced by using CPAP (0.34, 95% CI 9.9-32.4), avoiding a complication every 14 patients treated.
Doing anesthesia does not only mean intubating and extubating patients. It is necessary to know how to use the ventilator supports correctly and to extend the work even in the postoperative period .

Those aren't used in home CPAP therapy, they'd break the event differentiation ability of the machines.spiropulsator wrote: ↑Fri Oct 05, 2018 4:04 amWhat is the meaning of the reservoir bag used sometimes in the CPAP circuit?
