how is the ventilator mode adaptive support ventilation or ASV beneficial in the operating room setting?

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.

Roughly, it involves removing excess fluids and mucus from your lungs or otherwise trying to make your airways more open.  You can pound on the chest (yes they really do this in the hospital) which loosens mucus or you can do something called "incentive spirometry" which is kind of a lung exercise.  You breathe into a device with a ball that bounces up when you blow.  The object is to blow hard enough that the ball bounces higher.  This is supposed to keep your airways open (by making you breathe forcefully), thus preventing something called atelectasis (a collapsed lung).  Pulmonary toilet is indicated for patients who are receiving artificial respiration (on a ventilator) or for surgery or other bedridden patients who may have breathing complications from lying in bed for prolonged periods.  I have heard that incentive spirometry will prevent pneumonia but since that is caused by bacteria, I'm not sure that is true.

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.

I have asthma, and I love air conditioning!  I like to breath the cool air better than warm.  It can't be too cold, though.  That's not good.

An oxygen concentrator is a device used to provide oxygen to a patient at substantially higher concentrations than those of ambient air, used as an alternative to tanks of compressed oxygen.\n\nThe oxygen concentrator's internal functions are based around two cylinders, filled with a zeolite material, which selectively adsorb the nitrogen in the air. Each cycle, one cylinder is brought up to around 20 lbf/in² (138 kPa, or 1.36 atmospheres) while the other cylinder is brought down to 0 lbf/in² (0 Pa), allowing the captured nitrogen to dissipate. Typical units have cycles of around 20 seconds, and allow for a continuous supply of oxygen at a flow rate of up to approximately five liters per minute at concentrations anywhere from 50 to 95 %.\n\nIn both clinical and emergency care situations, oxygen concentrators have the advantage of not being as dangerous as oxygen cylinders, which can, if ruptured or leaking, explosively increase the combustion of a fire. As such, oxygen concentrators are particularly advantageous in military or disaster situations, where oxygen tanks may be dangerous or infeasible. Indeed, oxygen concentrators are sufficiently non-volatile that they are sometimes leased to individual patients as a prescription item for use in their homes, such as an adjunct to CPAP treatment of severe Sleep apnea.\n\nThese devices are currently in use by the US military in the conflicts in Iraq and Afghanistan, as part of the equipment complement of forward surgical teams.\n\nCommon models retail at around 2000USD, and require the authorization of a doctor for purchase. Leasing arrangements may be available through various medical supply companies and/or insurance agencies.\n\nhttp://en.wikipedia.org/wiki/Oxygen_concentrator\n\nTo meet Wikipedia's quality standards, this article or section may require cleanup.\nPlease discuss this issue on the talk page, and/or replace this tag with a more specific message.

Many oxygen bars use a concentrator, which filters out the nitrogen and other gases in the air circulating in the room, and then delivers the concentrated oxygen, about 95 percent pure, through a hose at a continuous flow rate. But oxygen users inhale the surrounding air along with the oxygen pumped through the nose hose, which decreases the concentration. The concentration is further decreased when oxygen is pumped through an aroma. According to one oxygen bar supplier, the customer gets less than 50 percent pure oxygen.\n\nFor further reading please visit: -

You can breathe as fast and shallow as you want and that's just what it is called "fast and shallow". Hyperventilation does not describe a breathing pattern, it describes what is occurring with gas exchange in the lungs. "Ventilation" refers to carbon dioxide diffusion into and out of the lungs. If you are hyperventilating, this means that you are blowing off too much CO2. If on the other hand you are hypoventilating, then you are retaining too much CO2. Hyperventilation can be caused by many things including pain, fear, anxiety, and stimulating drugs.

In the 1700's a number of people investigated gas behavior in the laboratory. Robert Boyle investigated the relationship between the volume of a dry ideal gas and its pressure. Since there are four variables that can be altered in a gas sample, in order to investigate how one variable will affect another, all other variables must be held constant or fixed. Boyle fixed the amount of gas and its temperature during his investigation. He found that when he manipulated the pressure that the volume responded in the opposite direction. For example, when Boyle increased the pressure on a gas sample the volume would decrease. Mathematically, PV = constant value if the gas is behaving as an Ideal Gas. A practical math expression of Boyle's findings is as follows: \n\nP1V1 = P2V2 \n\nwhere the variables with the 1 subscript mean initial values before the manipulation and the variables with the 2 subscript mean final values after the manipulation. \n\nA practical application illustrating Boyles Law would be the action of a syringe. When we draw fluids into a syringe, we increase the volume inside the syringe, this correspondingly decreases the pressure on the inside where the pressure on the outside of the syringe is greater and forces fluid into the syringe. If we reverse the actin and push the plunger in on the syringe we are decreasing the volume on the inside which will increase the pressure inside making the pressure greater than on the outside and fluids are forced out. \n\nA more life dependent example of Boyles Law is the ction of the diaphragm of our body. This is a muscle that is located just below the lungs. When we inhale the diaphragm moves downward allowing the lungs an increased volume. This decreases the pressure inside the lungs so that the pressure is less than the outer pressure. This results in forcing air into the lungs. When we exhale the diaphragm moves upward and decreases the volume of the lungs. This increases the pressure inside the lungs above the pressure on the outside of the lungs so that gases are forced out of the lungs. Of course, all of this is totally automatic and we take this important cycle which is performed hundreds of times a day for granted until we receive a sharp blow to that region that briefly paralyzes the diaphragm muscle. We say the wind was knocked out of us, but Boyles Law was not allowed to function.

Assuming you're talking about in the body: increased ventilation increases the amount of oxygen in your alveoli (lungs) and decreases the amount of CO2, the pH is buffered under normal circumstances by bicarbonate but more CO2 would lower the pH. Decreased ventilation gives the opposite effect of the ones mentioned.\n\nHope this helps

Sitting in a steamy restroom is good for asthma. It works like a humidifier and opens up the airway passage.

I believe it developed on time as a practical ecomonic choice or industry standard.\n\nYou would want to use a very low pressure if possible but still it needs to be high enough to actuate instuments and control devices.

the p is partial pressure. if the po2 is 65 depending on the patient that is on the low side. the pco2 means the patint is breathing a little fast, but not a bad pco2... i wouldn't extubate unless i knew the rest of the blood gas was ok? if the ph was 7.35-7.5 i would....  if the patient looked okay.... pulled good volumes on the vent

In our hosital, the CNAs do vitals q4h including pulse oximetry checks.  They will notify the nurse and the Resp care personnel if there is a problem with abnormal respers and/or low oxygen levels.  They help in CPR doing compressions AND bagging the patient, providing different equipment as it is asked for, taking notes on what is done, meds used and the time the meds or procedures are done.  Some of our CNAs are trained in reading cardiac monitors and I have trained a couple to do EKGs.  They know about CO2 narcosis so that they are aware of symptoms inorder to notify us if the symptoms exist in a patient.  They help in I & Os so as to notify the nurse if there is abnormal I & O ratio....I am not sure what you are looking for in your report, but basically, the CNA is our support system on several levels in the care of all patients and they have to know a problem when they see it.  Positioning patients is important for better breathing and the avoidance of bed sores....so many things are involved!  Our CNAs (nurse techs) are extememly important members of the patient care team.

Generally?  Well...get the FIO2 down below 50% ASAP...lowering as tolerated (I like O2 at 40% or less).  To wean...NIFs of course, lowering SIMV rate to at least six, pressure support....The NIFs mean a lot.  They are a pretty good indicator regarding the pt's ability to do well post vent/intubation......

unless you'll die of obesity shortly, DON'T get that surgery...  I've come across many people who spend a whole year in the hospital b/c of problems afterwards. some don't come off the ventilator they're placed on during surgery, others rupture their bowel (life-threatening, by the way).\nyou'll have most likely malabsorption, vitamin deficiencies, chronic diarrhea and vomiting... so, depending on what kind of job you do, they'll have to be very forgiving.\nregardless whether you get the surgery or not, you'll have to change your life //radically//.. afterwards only spoonful portions.. might as well do it without being forced to.

Instead of surgury a new recent method has come up in which a deflated balloon is inserted in thru the nose and then it is inflated to open up the vent/duct.Find more from your Dr.
