E is for Equipment
Some patients are overwhelmed by the equipment at the hospital. Here is an explanation of the more common things you may see on a cardiac (heart) unit of a hospital and the reasons for them.
Telemetry
Consider telemetry to be a wireless electrocardiogram (EKG) machine. Sticky electrodes are placed on your chest (just like with an EKG). These electrodes are attached to a small box that fits in the pocket of your hospital gown. A telemetry technician monitors what your heart is doing at all times. With this information, we can find out how fast your heart beats and whether the heart rhythm is normal.
Pulse Oximetry
A pulse oximeter measures the amount of oxygen in your blood. The actual device is a small piece of plastic that gently clamps the tip of your index finger. The pulse oximeter is attached to a wire which is connected to the telemetry box. Your oxygen levels are constantly monitored by a telemetry technician.
Intravenous Line
An intravenous needle (IV) is usually inserted into a forearm vein. Medications and fluids can be administered through your IV. If you notice redness, swelling, or pain at your IV site, tell your nurse or physician. We will examine the site and determine whether a new IV site is needed.
Oxygen Tubing
Supplemental oxygen is delivered through a clear plastic tube that is connected to the wall. If oxygen is ordered for you, a small attachment will be placed on the tubing so it can rest just inside your nostrils.
Foley Catheter
A Foley catheter is a thin plastic tube that inserts into your bladder to help collect urine. If you do not know understand the reason for your catheter, ask your nurse or physician if it can be removed.
Scale
There are many different scales in the hospital. If your physician asks that you be weighed daily, your nurse should weigh you on the same scale every day. If you notice that the scale is different, please let your physician know when he or she sees you that day.
