Which of the following are requirements according to Standard 2? (Select 3)

A. The patient must be accompanied by a knowledgeable anesthesia care team member.
B. The patient’s condition must be continually evaluated during transport to the PACU.
C. The patient can be transported without evaluating if stable.
D. The patient should receive support appropriate to their condition during transport.

A. The patient must be accompanied by a knowledgeable anesthesia care team member.
B. The patient’s condition must be continually evaluated during transport to the PACU.
D. The patient should receive support appropriate to their condition during transport.

C- For instance, if you have somebody who’s going back to the ICU, you probably are going to keep them on the cardiac monitor and check their blood pressure, pulse, oxygen sort of thing

On the other hand, most of our PACU patients will be be off all mechanical monitors and be more dependent on our observation skills.

Cornholio - Maybe it’s not common practice to transport patients on oxygen, but you’ve got to take them half mile.
Probably want to make sure you have oxygen. Do I need to take an Ambu bag with every patient? Probably not if I’m going across the hallway, but if I’m going a long way, it’s another story. Think about emergency medications and complications you can kind of encounter in between.

True or False

One of the biggest things we really worry about after anesthesia is hypovolemia.

FALSE

Corndog - *One of the biggest things we really worry about after anesthesia is hypoxemia. Are they older patients, people that are sedated that still have it in circulation. Do we have them on oxygen? Do they need oxygen? Is the oxygen adequate?

You will see that it’s part of your best efforts to monitor the patient and care for him that things will change between point A and point B. A patient that was 100% in the room may now suddenly be 50-60%, even though they’re still breathing…Having those monitors on quickly is pretty valuable.

True or False

The admissions report needs to be specific, organized, and completed only when you have the full attention of the receiving RN.

TRUE

C - So no matter what you do, as far as report, try and make it organized, if you just hop around, it’s very hard for people to kind of follow your train of thoughts.

We all run into people with ADD that only listen for about 5 or 10 seconds.
So if they stop paying attention, start doing something else, sometimes I’ll just stop talking and wait. Sometimes I stare at them.
Sometimes I’ll ask are they listening?
Especially if I’m going to give something kind of important.

It is a condition where patients have no airway obstruction during sleep. C. Patients with OSA are obviously prone to airway obstruction. D. Patients with OSA should be extubated while still sedated. E. Before extubation, patients with OSA should be fully awake and following commands. F. Patients with OSA should ideally bring their CPAP machine to surgery.
