what is a Nellcor N200 pulse oximeter? how are they used? what are its functions?

Generally speaking a pulse oximeter measures the amount of oxygen that is being carried in the red blood cells. It is continuous all the time or it can be used for a short period to check the oxygen in the blood at that time. 100% is perfect. Anything less than 93-95% is bad.

I don't understand your question. Tidal volume is measured using a respirometer. I'm not familiar with the other term.

In the Environmental Lab, we used the Parr Oxygen Bomb Calorimeter to measure the change of heat or capacity of heat for different substances.  What I basically mean is that we put the substance into a reaction vessel and then into the reaction container(bomb).  The bomb is pressurized,  filled with Oxygen, ignited and the data from the reaction is extrapolated to give us the Caloric Value for the substance.  \n\nWe took in Hazardous Waste for incineration in an industrial Kiln.  It was important to know the Caloric Value for these substances as it would determine how much other fuel (Usually natural gas) we would have to use to maintain the optimum temperature for the Kiln to operate.

An indoor rower is also known as an ergometer (slang ergo or erg). An ergometer being a device which measures the amount of energy or work performed. The indoor rower is calibrated to measure the amount of energy the rower is generating. Ergometer comes from the Greek word's ergon, meaning work and metron, meaning measure. An ergometer therefore is a device that literally means "work measurer".

It is basically a u tube manometer.\n\nThe pressure of air in one side (air inside an air bag) of the u tube is measured by the excess of mercury level in the other tube.\n\nThe air bag is made to surround one’ arm and pressure of air inside the bag is increased by pumping air inside.\n\nBecause of high pressure the blood circulation below the arm stops.\n\nBy slowly releasing the pressure and noting the pressure at which circulation of blood starts is noted. This is the highest pressure and again at a lower pressure the pulse is noted this is the lowest pressure.\n\n Systole refers to the contraction of the heart and conventionally systolic arterial pressure is the highest pressure developed in arteries during the ventricular contraction of the cardiac cycle. Diastole refers to a relaxed heart muscle and diastolic pressure has conventionally meant the lowest arterial pressure during a heart cycle. The pulse pressure is related to the amount of blood being pumped per beat. It is the systolic minus the diastolic pressure.

blood pressure cuff, also known as a sphygmomanometer

called a rebreather and it circulates your air and scrubbs it clean so you have air to breathe , closed loop system. its a large backpack thing and it requires special training. james bond thing is cool but non existent.

From 90% to 100% saturated of oxygen (at 2800 meters over sea level)\n\nMeaning your saturation is fine.\n\nWhy do you need it measured?

A sphygmomanometer (note spelling) works by completely cutting off the blood flow with high pressure, and then gradually decreasing that pressure until blood flows again.  The nurse determines this by listening with a stethoscope.  When she first hears blood begin to flow with a loud sound, that is the systolic blood pressure.  When the sound is no longer heard, that is the diastolic blood pressure.  So the cuff just reports how much pressure it is applying.  The nurse has to determine at what point the body responds.

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.

Nitrous oxide stays in your system only minutes after you stop inhaling it.\n\nIt is a very insoluble gas, which means it does not accumulate anywhere in your body.  That is why it works so fast.\n\nI work with nitrous on a daily basis as an anesthesiologist.  We monitor the gases that patients breathe out, and can watch the levels of nitrous decrease to zero very quickly (about 1-2 minutes) after we turn the gas off.\n\n(It is important to breathe 100% oxygen for a few minutes after turning nitrous off, because the nitrous in the blood floods the lungs and decreases the percent of oxygen that is breathed in.  Breathing less than 21% oxygen is unhealthy and can lead to serious problems.)

Pulmonary function tests or lung function tests are tests to measure the functioning of your lungs, and are used to diagnose diseases like asthma or Chronic Obstructive Pulmonary Disease (COPD).  A spirometer (a device that measures air flow that the patient blows into) is used to measure the amount of air that you breathe out of your lungs.  Based on measurements such as FEV1 and FVC, a trained technician can diagnose you for possible respiratory diseases.  \n\nFEV1 stands for forced expiratory volume for 1 second.  This is the amount of air that you forcibly blow out in one second after you take a very deep breath in.  An important point is that this is done while blowing forcibly and not just blowing like you're whistling.\n\nFVC stands for forced vital capacity.  This is the amount of air that can completely fill your lungs.  This is measured by taking a very deep breath in, blowing forcibly on the spirometer until you have no more air in your lungs, and you have to breathe in.

Medic Alert Bracelets?  I think that's the name you're thinking of.  My neighbor had one and it worked well, but then again she had used it inside her house.  I think you could get more information on them at your doctor's office or call your local fire department.  Either place would know.  Good luck to you and your grandfather.

"In recent years, electronic testers have become available for analyzing flue gases. [...] Most electronic testers use an electro-chemical cell as the gas sensing element. A different cell is required for each gas being measured.\n\nThe most common sensor used in oxygen testers is a zirconium oxide element that develops a voltage difference across two sides if there is a difference in oxygen concentration. The zirconium oxide element has the advantage that it can be exposed to flue gases for thousands of hours."

Sorry but the closest I can think of is the endoscope... but then it's not a bit similar to the stethoscope.\nFor checking the heart, a ECG can be used, though.

They are a measurement to determine oxygen consumption during exercise.\n\nMore mets, more oxygen used.
