AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a supine film).
An MRI system requires helium to keep its magnet cool, especially when imaging a patient, and continues to consume helium to remain cool when the magnet is idling. An MRI system must be cooled to 4.2 K, or -452Â° F, and liquid helium is the most effective way to sufficiently cool the magnet to that temperature.
In both the hospital and home settings, display an oxygen in use sign on the patient's door or the front door of the home to notify visitors and other family members that oxygen is in use and they must take extreme caution. Oxygen Storage. Depending on the setting, oxygen is supplied in different ways. In inpatient settings, oxygen is usually stored in large holding tanks outside of the building and piped in to patient rooms via outlets on the wall that are located behind the patient's bed. In home care, oxygen is usually supplied in small portable tanks. Always handle oxygen tanks with caution.
