i want to know if it is necessary for operating rooms to have adaptive type of ventilation mode in post surgical patients.for example, during open-heart surgery.

Well, in the 15000 cases I've done or taken part in, we hand bag the patients until we get to the ICU, or they're extubated in the PACU.\n\nASV has been discussed/used in all of our surgical units to some extent, however, and has it's uses, but can be completely absent, without mortality consequence.  It is a convenience setting, to some extent.

CPAP is Continuous Positive Airway Pressure machine is a device that delivers air at a constant elevated pressure to your airways usually during hours of sleep.It usually uses face masks or nasal prongs to deliver the air.\nThe most usual need for this is for a person who has OSA or obstructive sleep apnea\nHow does it work- well people with sleep apnea particularly the type that results from obesity loose airway muscle tone in deep sleep and this causes the airways to shut down and the oxygen saturaton in the blood to drop dangerously... the CPAP machine allows increased air pressure to be delivered to prevent these episodes.\n\nParameters? The settings are decided by an MD certified in sleep medicine (usually a pulmonologist or a neurologist) during a CPAP titration study.It takes into consideration several issues ...how you tolerate different masks..if you need supplimental Oxygen or not etc.  It is a very specialised field and you should follow recommendations form your sleep MD.

in case of an emergency... like you stop breathing during your procedure or something... that way they can get to you quick to work on you and not have to take the time to cut off all of your clothes with scissors.

We're taught to never hold our breath on ascent, no matter if it's an out of air emergency ascent situation or a normal ascent to the surface. The last breath we take in, at depth , grows in volume as we ascend. If we didn't constantly breathe with that all important exhalation, air in the aveoli (air sacs) of our lungs would grow in volume to the point they popped. You now get to drown in your own blood. \n By never holding out breath, we keep the pressure differential down to a minimum between ambient and internal.\n As for taking a deep breath before going down, it doesn't matter. We breathe at a normal rate, just like you are now and as long as we're not over exerting ourselves, that really doesn't change.\n\n Lol, diver dude, some really far out answers in there,eh?

Hostile work environment, I'd go with that, or consider calling OSHA (Occupational Health and Safety.) Noxious gases and high levels of bacteria are cause for concern for the workplace, right?\n\nDid they pass out eye protection in your office?\n\nHow about Scott Air Packs or other respirators? Are they in easy reach of anyone who might require them?\n\nIs there an adequate alarm system? I suggest that rotating flashing lights above the bathroom door (warning the unwary not to enter) plus sirens and a loudspeaker announcing when it is safe to re-enter the workspace might be something to consider.\n\nWhat about running "fire" drills. If you see the Comptroller heading in the general direction of the loo, your health and safety officer is completely within his rights to pull the alarm and announce a general evacuation of the premises. Then he should conduct a role call at the designated meeting areas.\n\nIt might be wise to practice administering CPR (preferably on the prettiest women or guys, if that's your preference) \n\nIt might not be too extreme to demand that the Comptroller's favorite stall be marked off with biohazard tape and flooded with strong UV. Ask about installing a huge fan to whisk toxic fumes out of the building. In fact, an executive "washroom" with a special lock should be built just for this guy....\n\nIn the next county.

Yes. For example when performing CPR there's the Dr ABC steps. The breathing is checked before the circulation is. Once the breathing step has been fixed you move on to the circulation. If it wasn't possible to breathe without circulation you'd have to do it the other way around, i.e. fix the circulation before you can move onto the breathing.

It's a sealed room with high barometric pressure.  Sometimes if divers come up too soon, they get a condition called "the bends" in which nitrogen dissolved in the bloodstream starts to come out as bubbles of gas.  (Think of how bubbles come out of soda when you lower the pressure by opening the top.)  So the divers can be put in a hyperbaric chamber, where more of the gas will stay dissolved and the pressure can be lowered gradually.

I know this is prob not the answer you are looking for.  I have been a CPR instructor for almost ten years now.  I keep up with journals from the American heart assoc. and the American health and safety inst. (just kidding about ashi all they do is copy aha, but i digress)  I have not heard, read, or seen anything about a 200 compression CPR.  i have heard studies about no rescue breaths, compression only CPR and it was found to be to existing for the rescuer.  the new standard is 30 compressions to 2 breaths.  This was found to be optimal in maintaining oxygenation of the blood ( the whole reason you are doing CPR)\n\nhope this was some sort of help..\n\naddendum,  200compression is continuous compression CPR or ccc.  it is being used in some parts of the country.  Normally it is in correlation with a commercial chest compression device (thumper) that mechanically does the chest compressions for you.  I will add more findings as my wife allows me on the pouter.

from Wikipedia:\nhttp://en.wikipedia.org/wiki/Ventilator\n\nA medical ventilator is a device designed to provide mechanical ventilation to a patient. Ventilators are chiefly used in intensive care medicine, home care, and emergency medicine (as standalone units) and in anesthesia (as a component of an anesthesia machine).\n\nIn its simplest form, a ventilator consists of a compressible air reservoir, air and oxygen supplies, a set of valves and tubes, and a disposable or reusable "patient set". The air reservoir is pneumatically compressed several times a minute to deliver an air/oxygen mixture to the patient; when overpressure is released, the patient will exhale passively due to the lungs' elasticity. The oxygen content of the inspired gas can be set from 21 percent (ambient air) to 100 percent (pure oxygen). Pressure and flow characteristics can be set mechanically or electronically.\n\nVentilators may also be equipped with monitoring and alarm systems for patient-related parameters (e.g. pressure and flow) and ventilator function (e.g. air leakage, power failure), backup batteries, air and oxygen tanks, and remote control and alarms. The pneumatic system is nowadays often replaced by a computer-controlled turbopump.\n\nModern ventilators are electronically controlled by a small embedded system to allow exact adaptation of pressure and flow characteristics to an individual patient's needs. Fine-tuned ventilator settings also serve to make ventilation more tolerable for the patient. In Germany, Canada, and the United States, respiratory therapists are responsible for tuning these settings.

normally no. but it will depend on the region and mass that has been taken along with the medicines that you are taking after the operation.\nanyway this is common to many patients which usually gets resolved spontanously with time.\ntake care ,\nmay god help you

I' m not sure why at this point someone has not addressed surgery. Is she being followed by a cardiologist? Unless something else is the cause of what sounds to be heart failure, it seems like her regurg. is finally become symptomatic. Has no one approached her about surgery? Has she been told for some reason that she is inoperable? You definetely don't want to jump into surgery if you dont need to. I feel like I need more info to adequately answer your question though. What I would do is direct these questions towards her doctor, preferably a cardiologist. Has she had a heart cath yet?  If not, maybe see if its time. Email me if you find out more or if you have anymore questions. Im a RN in the cardiovascular ICU, I specialize in heart surgery. Good luck to you guys!

The new machines account for subtle movements while the operation is being performed, so it's safer than before. I've heard that during the first few weeks you have have some side effects like halos around lights during the night, but they go away. \n\nI would have done it, but my retina is too thin, and it would be too dangerous.

Generally no because during intubation assuming you are having a general anaesthetic, intubation may be difficult and increase levels of sputum in the lungs puts you more at risk.\n\nSurgery is risky anyway why increase the level of risk when you don't have to.

Liquid Breathing\n\nA lot of you I am sure have seen the movie "The Abyss". If not then it doesn't matter but what is important however, is one of the diving techniques that they use. This technique is called Liquid Breathing. Until not long ago, people thought that this was fictitious and was not possible but in fact it has been around for a lot longer than you might think!\n\nThe general type of liquid used by the US Navy and other Navies in the world generally have a perfluorocarbon type composition. The type of halide attached onto the molecule depends but it is either fluorine or bromine. However, the only problem associated with using bromine is that it is a very strong greenhouse gas but it could be regenerated through special filters and rebreathers.\n\nADVANTAGES\n\nIt  seems like an odd concept but:\n\n1- Due to its density, Liquivent (marketed name for liquid breathing liquid) can carry as much as 25 times as much oxygen than blood and it has enormous potential for patients with lung and breathing disorders. \n\n2- If fluid is taken into the lungs whilst diving, then the pressure in the body could match that of the pressure of the surrounding water. Thus breathing would be easier and lower concentrations would only be needed. \n\n3- Thus, this would also eliminate the need for decompression and its inherent problems i.e. nitrogen narcosis and the bends.\n\n4- A given volume of oxygen-saturated fluorocarbon contains 3 times as much oxygen as the same volume of air or whole blood.\n\n5- According to the movie "The Abyss", the deepest suit dive was to 4800ft which is equivalent to about 300atmospheres of pressure! Tests with mice have been done at pressures of up to 8000ft.\n\nHISTORY\n\nThis concept originated in the mid 60's when Dr Kylstra a physiologist realised that salt solutions could be saturated with oxygen at high pressures. However, after several experiments he concluded that this mixture becomes toxic due to the build up of carbon dioxide. Therefore, a new mixture that could be saturated with oxygen and get rid of carbon dioxide quickly and efficiently had to be thought of.\n\nAfter further experimentation in 1969, Dr Clark realised that oxygen and carbon dioxide were very soluble in fluorocarbon liquids like freon. Assuming the lungs could cope with this material, Dr Clark figured that these fluorocarbons could support respiration of animals.\n\nLater developments\n\nDuring later years, the techniques of liquid breathing were constantly refined and improved. The survival rate of all the tested animals in recent years has been very high, thanks mainly to improvements in carbon dioxide elimination. Current liquids used can dissolve over 65 ml of oxygen and 228 ml of carbon dioxide per 100 ml perfluorocarbon. By the early 1990s this procedure was developed:-\n\n   1. The animal was anesthetized with intravenous sodium thiopental.\n   2. The animal was put on its back. A tube was placed down its airway, ready for the liquid breathing medium.\n   3. A blood sample was taken. The temperature of the liquid was adjusted correspondingly. It was no longer necessary to make the animals hypothermic.\n   4. The perfluorocarbon was instilled into the animal's lungs through the tube.\n   5. A floor-mounted 3-litre reservoir was filled with the perfluorocarbon. The liquid was driven by a pump through a series of machines which warmed and oxygenated the liquid and took the carbon dioxide out of it. The liquid flowed through a tube into a 3-way pneumatic valve which directed flow to the animal. A computer controlled the inspiration (18 ml of fluid per second), pumping the liquid into the animal's lungs, then back out again to the reservoir, at a rate of about 6 complete respirations per minute.\n   6. At the end of the test, the animal was tilted for about 15 seconds and the perfluorocarbon was allowed to drain from the lungs. This can be seen in the film The Abyss where Ensign Monk drain

I haven't had the surgery, but I'm a nurse that work for an ear, nose and throat doctor in surgery and have performed plenty of them. If done correctly, yeah, it should help with breathing and stuffiness....not allergy symptoms though. It's "involved", but not difficult. Usually takes an hour, give or take and you'll be a little black and blue for a week or so. Good Luck!

I'm not certain what you're asking, so I'll just dump out the information that may be relevant.\n\nVentilation is the process of getting usable oxygen into the lungs.  Perfusion is the process of circulating blood to the lungs to pick up the oxygen.  When your patient has the oxygen mask on, you are increasing the ventilation by increasing the concentration of oxygen entering the lungs.  This, in turn, will not increase the perfusion since it has no effect on the blood vessels, but will increase the efficiency of perfusion because of the increased oxygen gradient.

Hyperbaric therapy does help people that have the "bends" (decompression sickness) and helps in healing by increasing the amount of oxygen the blood can hold. It's been used in the treatment of burns, carbon monoxide poisoning, smoke inhalation and flesh eating bacteria.\n\nIt should only be done as prescribed by a physician as there are some dangerous side effects. If you have asthma it will increase the likelihood of cerebral arterial gas embolism. (sudden onset of unconsciousness associated with a generalized or focal seizure. There is often confusion, vertigo (extreme dizziness) and cardiopulmonary arrest.) In other moderate to severe forms of COPD, it's likely the person will cease to breathe. There's also barotrauma to the ears.\n\nIf you live in the U.S., it's expensive and insurance will only cover it as prescribed by a doctor.  I can't imagine this as an elective procedure unless there is strong medical need for it.
