Over the past few months we have had more CrCU, B5ICU and D4ICU patients staying for extended periods in PACU. Patients who are intubated (and are expected to remain intubated,) have central lines, or chest tubes inserted in the OR MUST have a post-op CXR done to check placement of these invasive lines. It is a safety issue, hospital protocol, and the expected standard of care. Please refer to Central Line Insertion and Chest Tube Insertion. Management of the patient who remains intubated and/or ventilated is an advanced nursing competency, and as a PACU RN there is a professional responsibility and accountability to ensure that the skill is maintained in a competent and safe manner. If anesthesia does not order a CXR post op, please remind them that it is necessary, and insist upon it! Let them know that you will page them once the CXR has been taken. Also, if you know that a patient is going to remain intubated for an extended period of time, it is prudent to have an order for an NG Tube (if the patient does not have a basal skull fracture.) A good time to insert this would be prior to the CXR being taken. 
As you all know, we have been on a MAJOR hiring spree this year! Please help me to welcome our newest PACU employee, Hongling Wu. Hongling comes to us from the ICU at Humber River Regional Hospital. 
The following letters were received from a past patients.
Letter #1
Attention SSSU PCM CAROL DERIET
Just a note to say how wonderful the nursing care was when I was in the short stay unit on Fri. Apr. 25. There was 4 nurses Fri afternoon-Debbi & Debbie and Maggie & Martha overnight. I found them to be kind, pleasant, considerate and most helpful.
I hope they will continue to serve for many years to come.
Please pass my thanks on to them! Sincerely, Joseph G.
Letter #2
Dear Dr. McLellan,
I would like to take this opportunity to share my very positive experience that I recently had with Sunnybrook and Dr. Marks in connections with my ACL replacement surgery. It was my first time to have surgery or any medical procedure for that matter and I must say the whole operation was very professional and efficient/ While it is not possible for me to remember all of the names of those that were involved in my surgery I would like to say that the medical and support staff that assisted me were all first class professionals. This includes my initial contact and visit with Dr. Marks' and his office, the pre-op session a week before mu surgery, the pre-surgery prep and the post surgery recovery. It is hard to tell what actually went on while I was in the operating room as I was knocked out-but all indications are that it was a big success!
Please pass this note on to all the departments involved as I would like to thank them for the excellent medical care they provided to me.
Yours truly,
Daniel C.
Most of you have probably seen this joke before, but it's funny the second time around too!
Visit the Earth Day Canada website at http://www.earthday.ca/pub/index.php for a list of Earth Week events in your area that you and your family can participate in. ~Bring a ‘litter-less’ lunch to work all week (no plastic or foil wrap). Continue this practice beyond Earth Week. This includes bringing reusable mugs when buying coffee and other refreshments at the coffee counters. Tim Horton’s and Second Cup offer discounts to those using their own mugs!
Impact
· Reduce your waste – In a lifetime, the average North American throws away 600 times his/her adult weight in garbage.
~ Always turn taps off tightly at work and at home.
~ At home and at work, develop the habit of defrosting frozen food in the fridge overnight instead of running water.
Impact
· Conserve water –A faucet that drips one drop per second wastes nearly 12,000 litres of water per year.
· Check for leaks in your toilets at home – a leaking toilet can waste up to 400,000 litres of water or about $730 per year.
~Avoid printing paper – try to use email instead of paper copies whenever possible. If necessary, use double-sided photocopying or printing.
~Install low-flow aerators on your faucets at home. (Aerators are small fixtures added to the water stream, reducing water flow while keeping the same pressure. Very easy to install and cost is under $10)
Impact
· Approximately 80% of office waste is paper and of that, 70% is not recycled.
· Low-flow aerators can reduce the water usage of faucets by as much as 40% from 4 gallons per minute to 2.5.
~Take public transit, ride a bike, walk or carpool with friends and co-workers to work
Install energy efficient compact fluorescent lights (CFL) at home.
~Recycle old computers and computer equipment for FREE (during Earth Week) by dropping it off at Computation – located at 280 Jane Street, between the hours of 10am and 7pm.
http://www.computation.to/recyclingEvent.html
Impact
· One city bus eliminates the emissions of 40 cars.
· Save money and use less energy - A single 18 watt CFL used instead of a 75 watt incandescent
will save about 570 kWh over its lifetime – that’s $45 in savings (at 8 cents per kWh).
~At home and at work, always turn off lights, printers, faxes, computers, etc. when they aren’t in use. At home? Unplug all electronic devices when not in use (e.g. toaster, kettle, blender, coffeemaker, battery charger, etc.). OR: You can plug your electronics into a power bar that can easily be switched off.
Impact
· Electronic devices still draw power even when they are turned off. This is called standby power.
· Over a year, electronic devices at home can draw enough standby power to run a refrigerator for a month. (who knew?!)
~In the GTA? Bring your family and friends to the Annual Trees across Toronto city-wide planting event from 10am – 12pm. Locations can be found at this website: http://www.toronto.ca/parks/treeadvocacy.htm
Impact
· Trees help reduce the effects of global warming by absorbing carbon dioxide.
· A single mature tree can absorb 48 lbs of carbon dioxide per year and release enough oxygen to support two human beings.
This policy was forwarded to me today, and I thought it might be useful to know where to find it. It might come in handy when working shift or weekends?!
The ICP waveform results from transmission of arterial and venous pressure through CSF and parenchyma.
P1 (percussion wave) and reflects cardiac systole
P2 (tidal wave) reflects cardiac diastole
P3 (dicrotic wave) is located immediately after the dicrotic notch and sloped into the diastolic baseline portion
Analysis of the ICP waveform should include an assessment of the wave amplitude and the configuration of the wave (P1, P2, P3,).
As the ICP rises, so does the amplitude of the three wave components. Persistent elevations usually cause P2 to increase more than the P1 or P3 components, resulting in a rounded appearance of the pressure wave.

See how P2 is higher than the other waves? P1 is supposed to be the highest. Not a good thing – this means that overall the ICP is rising – higher wave, higher pressure.
the elevated P2 means that the intracranial compliance is probably decreasing, as the pressure is rising. Makes sense – pressure rises, things get less compliant, more rigid.
Monroe-Kellie Hypothesis!
Hopes this helps clarify the question, Sandi. Thanks for asking!
Last week, Henry Sinn, Director of Medical Imaging spoke to a few of the nurses working on MGround. To make a long story short, he was adamant that xrays were of negligible safety concern for nurses and patients in a common room where xrays were being taken. Basically, the cassette that the xray is placed in absorbs 85% of the rays. Safe xray practice includes keeping minimally 3 feet away from the patient during xray, and keeping out of direct line of the xray shot. The xray tech also centres the picture on the patient area to be xrayed so that as many of the radiation rays are absorbed on the cassette. Henry said that the techs and RN's actually do receive scattered radiation from the patient after the xray has been taken as the patient naturally absorbs some of the radiation. For portable xrays, the cardinal time is 0.1 seconds of exposure.
This might be of interest to some of you! Check out the information HERE
