Man, I hate those new water towers. One day about 10 years ago at one of the places I worked a painter fell off one just like this and was killed. It was horrible. Wasn't wearing his safety equipment. The nurse on our unit was the one who arrived first and he had fallen from the top of the tower all the way down onto the parking lot. She was past shook up when she returned, as you can imagine. It was especially sad because the facility was in the last steps of closing and within two years everyone had moved out and now the place sits abandoned.
you are correct it is used for respitory meassurements. its now caled a peak flow meter easly google it. most asthmatics use one every day and once every three months they have a lung capacity check
Poseys - the best restraints out there! We still use them - almost exclusively for stabilizing limbs after injuries but infrequently on people who are severely self-abusive (beat their heads until they are bloody, try to pull their eyes out, things like that). If someone has just had an operation and tries to pull out all the equipment and such that keeps them alive (IV lines, catheters, feeding tubes, oxygen, etc.) we go through the necessary hoops for short-term posey restraints. Lots of paperwork, consents, human rights committees, monitoring, hourly documenting, etc., but they buy time for the person to mend. Otherwise the equipment is pulled off/out as soon as the person wakes up and then they have a significantly increased chance of death or permanent injury.
Those Mental Measurements Yearbooks by Buros are what we psychologists use to check the statistical properties of the tests we use - reliability, validity, sample size, power, etc. Very handy if you ever have to go to court. :-)
