Leveraging XPAPs in COVID-19

By Laurie Gelb, MPH, BCPAWith thousands of CPAP and BiPAP machines (xPAPs) in US closets and inventories, the FDA has issued an emergency authorization for the use of positive pressure devices in COVID-19. These can be leveraged in hospital and home settings for noninvasive support, and, if/as modified, for invasive ventilation as well.xPAPs in the HospitalIn a negative pressure room, xPAPs can be repurposed as a closed circuit system, avoiding an aerosol of infectious droplets.

In other settings, an N95 mask viral filter xPAP can serve a similar purpose.A Bay Area group, including members from UC Berkeley and San Francisco, is collecting xPAPs from across the US to repurpose with a viral filter under the FDA authorization. The Mount Sinai system in New York recently modified 200 VPAP S/T units in similar fashion.

In addition, portable ventilators with oxygen inlet adapters such as the Astral (ResMed) and Trilogy (Respironics), albeit with a more limited pressure range, can be used either invasively or non-invasively, and can operate on internal battery power in field settings.As another option, European physicians have piloted a single-patient modified snorkel mask, using a 3D-printed valve as a machine attachment. In the US, Northwell Health System and others are using 3D-printed adapters to run standard xPAPs as ventilators.

Other applicable xPAP adaptations are discussed on physician forums and may be reflected in forthcoming federally-authorized equipment production.xPAPs in the Home SettingOften, patients with conditions such as COPD, sleep apnea, and/or neuromuscular disorders, have CPAP or BiPAPs.As of April 1, Medicare patients access to xPAPs and related equipment has been extended, with more lenient requirements, so for patients with an emerging medical indication or cases for whom an authorization is in progress, this could be a good time to finalize an equipment order.

Once a patient has suspected or confirmed COVID-19, the benefits of continued unmodified xPAP use should be weighed against potentially greater transmission risk, especially with high-risk household members.If xPAP use is continued, machine settings may require adjustment for optimal effectiveness (not only in COVID-19 infection, but in other respiratory infections as well). Potential adjustments include:Changing volume support modes (e.

Adjusting pressure settings to comfort.Increasing trigger sensitivity for faster inhalation support, or decreasing it so gasps do not prematurely trigger the machineAdjusting cycle sensitivity to support shallow breathingRemoving backup rates, if/as this can be done safelyIntermittent mouthpiece ventilation during uncontrolled coughing may be more practical than a mask. An angled 22mm mouthpiece, also used for nebulizers and available for online purchase without a prescription, can be attached to the xPAP hose, and then mounted in an accessible location.

xPAP hoses are available in lengths up to 10'.Machine humidification may require adjustment. Filters and hoses should be kept clean to avoid cross-contamination and potentially reinfection.

Patients who need information on how to modify settings may contact their respiratory therapist or DME supplier, or access instructions online. Disease-specific forums can often assist as well. Other Home Care SuppliesPhysicians may recommend a pulse oximeter and/or BP monitor for COVID-19 patients at home, as well as a thermometer.

Clinicians can pre-specify appropriate action should sats, temperature, pulse, or BP fall outside a threshold range: contacting the primary physician, self-transporting via an in-home caregiver, or calling EMS.As always, caregivers for patients with infectious diseases or symptoms, are advised to call ahead to ERs if self-transporting, or advise the EMS dispatcher accordingly, so that PPE needs can be relayed to responding personnel. fda.

Learn to Choose Between CPAP and BiPAP | HPFY
When sleep apnea rears its ugly head there can be some serious health concerns that can negatively affect your quality of life. Not to mention being potentially hazardous! The value of a good nights sleep is often greatly underrated. Interruption of your nightly sleep can have long-lasting effects throughout the day. In order to combat sleep apnea, the use of a CPAP/BiPAP machine may be your greatest ally, but which one is ideally suited for you? Here is some help.So what is the big deal about this sleep disorder? Obstructive sleep apnea is a condition in which there are pauses or interruptions in breathing of 10 seconds or more during sleep. It is characterized by loud snoring, abrupt waking (accompanied by gasping or choking), daytime drowsiness, dry mouth or sore throat, and observed periods of breathing cessation during sleep. As you can imagine, this sleep disorder can wreak havoc on your next days productivity.How to treat Obstructive Sleep Apnea?Approximately 1 in 15 Americans suffer from obstructive sleep apnea. This constitutes 6.62% of our population. Many individuals can be affected as often as every thirty seconds with an episode of obstructive sleep apnea. It cannot only affect the patient but their sleep partner equally since they too can have interrupted sleep. The common treatment for obstructive sleep apnea is to apply air pressure in the back of the throat in order to keep the airway open. By gently applying pressure to this area, the obstruction usually caused by the palette or tongue area falling to the back of the throat can remain open and allow for normal breathing during sleep. There are several causes of obstructive sleep and they can include being overweight, enlarged tonsils/adenoids, excessive alcohol consumption, and smoking. By applying gentle pressure through a CPAP/BiPAP machine, this can lead to a more restful sleep and a possible elimination of potentially dangerous health effects down the road.How to choose between CPAP and BiPAP?The two main pieces of medical equipment used to combat obstructive sleep apnea are CPAP and BiPAP machines. They both work by applying gentle pressure to the obstructed area, but they do it in considerably different ways. The main differences are:What is CPAP?This acronym stands for Continuous Positive Airway Pressure and delivers a constant pressure through a tube to a mask that covers the mouth or nose. This pressure is set by your physician and should not be altered unless ordered to. Look to the DeVilbiss InteliPAP 2 AutoAdjust Auto CPAP Machine for simple, easy CPAP therapy for restful sleep.What is BiPAP?This is a machine that also applies pressure and stands for Bi-level Positive Airway Pressure. The bi-level refers to an inhalation pressure and an exhalation pressure. BiPAP is a trademark of Respironics. For those with breathing restrictions, BiPAP makes exhalation easier (which is good for those who need a higher inspiratory pressure). Users should try the DreamStation BiPAP Pro Machine with Humidifier to benefit from BiPAP therapy.Whether a CPAP machine or a BiPAP machine is right for you, the accessories for both are the same. The mask, tubing, and any other piece of equipment are more or less interchangeable between the two machines.So, which machine is better? This is not a simple question, but BiPAP is sometimes used when CPAP is not tolerated by the patient. Also, BiPAP can be used in patients with lung issues such as COPD, plus the use of two separate pressures helps reduce CO2 gas from the body. When using a CPAP machine you could encounter bacteria and other contaminants in your mask or tubing, even if you hand wash and dry your equipment. This can lead to sinus infections and other nasty problems down the road. The best way to keep your CPAP machine and equipment functioning efficiently and properly is with the SoClean 2 CPAP Cleaner and Sanitizer. This simple, easy to use sanitizer can clean, disinfect, and sanitize your CPAP mask, tubing, and reservoir without disassembling everything every day. Talk about convenient! If you are developing sinus infections and other issues, the efficacy of each treatment is diminished. This sanitizer can destroy up to 99.9% of CPAP germs, bacteria, and other pathogens giving the user peace of mind. Also, the SoClean 2 is compatible with most CPAP machines.Therapy for obstructive sleep apnea can greatly improve your quality of life and head off potential health issues that can seriously affect your everyday well-being.

Brief Analysis of the Current Development Status and Trend of Chinese Medical Device
  Author:MeCan Medical–ultrasound machine manufacturersAt present, the epidemic is still spreading globally, and international trade and economic growth have stalled. Although the exports of Chinese medical equipment remain stable as a whole, they need to be alert to relevant risks and challenges. The relevant person in charge of the Medical Institution Department of the Medical Insurance Chamber of Commerce pointed out that in the short term, due to the needs of epidemic prevention and immunity, the global market has increased its dependence on the supply chain of Chinese medical device.In the long run, the epidemic has become a catalyst for reshaping the global industrial structure. With the introduction of policies in various countries, international competition will intensify, and the competition between Chinese medical devices in the global market will be more intense.In terms of market risks, the global economic recovery will lower the ability of the international market to procure ordinary medical supplies. The surge in demand for epidemic prevention materials, coupled with the decline in the efficiency of the port work, has caused serious lag in the circulation of containers, bringing a sharp increase in international logistics costs, especially shipping. The rise in raw materials and labor costs, and the strengthening of the supervision of merchants by cross -border e -commerce platforms will further squeeze the export profits of the enterprise.In addition, due to international travel restrictions, it is difficult for engineers and sales staff to conduct promotion activities in overseas markets and after -sales service for some large -scale equipment exported equipment, and it is not conducive to market sales.Overseas market expansion also needs to focus on the impact of changes in international market regulations. For example, the European Union has implemented new medical device regulations (MDR) and in vitro diagnostic medical device regulations (IVDR), pay more attention to the clinical performance of the product, strengthen the traceability of medical device products, and pay attention to improving the transparency of patients.These will improve the management and restrictions on medical device products entering the European market accordingly, and put forward higher requirements for the industry's employees, which will bring about increased costs to Chinese export companies, extending certification cycle, and increasing compliance risks, etc. challenge.

  Author:MeCan Medical–ultrasound machine manufacturersThe enzyme missionary instrument is commonly known as the enzyme -linked immunohistic detection instrument. It can be simply divided into two categories: semi -automatic and fully automatic, but its working principles are basically the same. The core of its core is a color meter, that is, the color method is used to analyze the content of the antigen or antibody. Clinical examination, biology research, agricultural science, food and environmental science. Let me introduce the application of enzyme -linked immune detector in pesticides and food.1. Fast diagnosis of animal epidemic.The enzyme -linked immune analyzer adopts the enzyme -linked immune adsorption measurement method and the corresponding reagent with a qualitative or quantitative animal disease diagnosis. Such as: pork blue ear virus, swine fever virus, pig pseudo -rabies virus, pig pseudo -rabies virus GE protein, pig ring virus, pork type encephalitis virus, pig mouth hoof disease 3ABC protein, pig mouth hoof disease virus IgG, pork fine virus, chicken chicken, chicken Bird flu, blue tongue disease, white spot syndrome, cattle infectious pleural pneumonia, cattle plague, cotton acne, and sheep acne detection.Second, pesticide residues.Organic phosphorus pesticides are commonly used in agricultural production in my country. Common types include methylmine, dichlorvos, oxygen fruit, phosphorus, and enemies. Most of them are highly toxic pesticides. By reducing the activity of cholthyne enzymes in the body, delayed neurotoxicity is caused, thereby achieving the purpose of eliminating pests. The enzyme -linked immune detector can be used to detect the methamidine content contained in fruits and vegetables.Third, food safetyThe enzyme -linked immune analysis method uses the special nature of the antibody and the corresponding antigen to detect the antibody contained in the food based on this. The immune enzyme method is to use specific enzymes as detection tags and reaction catalysts. The use of this method can be used to effectively avoid using radioactive elements during the detection process, or to conduct orientation and quantitative analysis of the detected objects. , Chemical residue, edible oil testing, water and wine beverage analysis, condiments, edible pigment, etc.At present, more automatic enzyme -linked immune detectors can be used for qualitative detection and quantitative detection. The detection only takes a few hours. It not only reduces the labor intensity of laboratory personnel, but also greatly improves the accuracy and repeatability of the determination. This is conducive to the further commercialization of ELISA technology in detection and analysis.

How Does the Magnetic Pearl Nucleic Acid Extraction Extract Nucleic Acid and Where Is the Advantage?
  Author:MeCan Medical–ultrasound machine manufacturersAs one of the current effective epidemic prevention and control methods, nucleic acid extraction and testing are no stranger to everyone. Prior to this, the method of extracting the traditional nucleic acid was chemical cracking and cylindrical method. However, with the rapid development of gene diagnosis, genetically modified food detection, and personalized medical care, traditional nucleic acid extraction technology can no longer meet the needs of today's biotechnology. As a result, magnetic pearl nucleic acid extraction came into being.No. A commercialized reagent that used the magnetic bead method to extract DNA and successfully applied for patents in the United States appeared in 1998. The magnetic bead method first absorbs the free nucleic acid molecule to the surface of the magnetic particles by cracking the cells, while the protein and polysaccharides are left in the solution. Under the influence of the magnetic field, the magnetic particles are separated from the liquid to discard the liquid to eliminate the liquid Later, the purified nucleic acid molecules were obtained after being eluted.The magnetic bead method uses the principle of combining and dissipating the magnetic acid activity group with a magnetic granular activity group under certain conditions to avoid the loss of nucleic acid during the extraction process as much as possible, and it can also remove the interference substances in the specimen (such as hemoglobin The effects of bilirubin and lipid blood), obtain high -quality nucleic acid templates. With the development of magnetic bead method extraction technology, DNA extraction has really begun to achieve standardization, rapidness and automation.The kits based on the magnetic acid extractor of the Magnetic Pearl Method are also widely used. Nucleic acid extraction kit does not require any organic solvent and no need to repeat centrifugation. At present, it can extract high -quality DNA and RNA from full blood, serum, plasma, saliva, urine, feces, cerebrospinal fluid, tissue and cells, and shorter time. The recovery rate is higher. And it can be automated and uninvited through mechanical equipment.In addition, the principle of magnetic pearl method is safe and non -toxic, and does not use toxic reagents such as benzene and chloroform in traditional methods. Mainstream nucleic acid extraction methods at home and abroad.

In fact, with the normalized management of the epidemic, the nucleic acid extract instrument, as one of the commonly used equipment tested by various hospitals, has a higher frequency and the number of purchases has continued to rise. In fact, although everyone is familiar with the term of the nucleic acid extract instrument now, but it is very familiar with the term, but it is very familiar with the term of the nucleic acid extract instrument, but it is very familiar with the term, but it is very familiar with the term. I do nt know how to work and test the method of working principles. Let s take a closer look at the editor of Prank Medical Equipment.There are many classifications of nucleic acid extract instruments. In fact, the most commonly used is magnetic bead method. How does this method work? Magnetic pearl nucleic acid extract instrument is generally divided into two types: suction method and magnetic stick method. The specific operation process is as follows:First, suction method. The extraction of nucleic acids is achieved by fixed magnetic beads and metastasis liquids. Generally, the transfer of the robotic arm is generally controlled by the operating system.1. Crack. Add a cracking solution to the sample to achieve mixing and adequate reactions of the reaction solution through mechanical exercise and heating, cell cracks, and release nucleic acids.2. Adsorption. Add magnetic beads to the sample cracking solution and mix it in full. Use magnetic beads to adsorb nucleic acid under high salt and low pH value. Under the action of magnetic fields, the magnetic beads are separated from the solution. Mo the liquid out of the waste liquid tank and abandon the head.3. Washing. Remove the external magnetic field, add the new suction head to add the washing buffer, mix it fully, remove the impurities, and remove the liquid out of the magnetic field.4. Requesting. Withdrawing the magnetic field and adding the new suction head to add the elution buffer, fully mixed, the combined nucleic acid is separated from the magnetic bead, so as to obtain a purified nucleic acid.Second, magnetic stick method. By fixed liquids, the magnetic acid is separated to achieve the separation of nucleic acids. The principle and process are the same as the pumping method. The difference is the method of separation of magnetic beads and liquids. The magnetic stick method is to separate the magnetic beads from the waste liquid through the adsorption of the magnetic rod to the next step to achieve the extraction of nucleic acid.In fact, the characteristics of this magnetic pearl nucleic acid extract instrument is that it can achieve automation, high -throughput operations, safe and reliable operations, high efficiency, and pollution -free. Therefore, it is recognized by many buyers. When choosing a nucleic acid extraction instrument equipment, no matter which type of device is selected, you must have a basic understanding of it. You cannot judge the quality of the product from the price alone. For more product details, you can consult: 400-6656 -888.
