Alarms

Patients are monitored continuously in ICU. When you hear an alarm it doesn’t necessarily mean something is wrong, just that there’s something the staff need to be aware of.

Arterial Line

A special IV placed into the artery to continuously record blood pressure and to allow the sampling of blood without sticking the patient with a needle.

Breathing Tube  (Endotracheal Tube)

A tube placed through the mouth into the windpipe to deliver air and oxygen to the patient’s lungs and remove secretions. Patients cannot talk while the tube is in place.

To “intubate” means to insert the breathing tube, while “extubate” means to remove the breathing tube.

Mechanical Ventilator (Breathing Machine)

A machine attached to a breathing tube to help a patient breathe in a specific depth and pattern. The ventilator also provides oxygen.

“Weaning” means decreasing the amount of work the mechanical ventilator does and gradually allowing the patient to breathe on their own.

Central Line

A catheter that is inserted into a large vein (usually in the neck, groin or arm) that allows continuous delivery of fluids and medication.

Sedation

Tracheostomy tube (Trach Tube)

A small plastic tube placed through a hole in the patient's neck into the windpipe.  This helps a patient breathe better and allows them to be weaned from the breathing machine.

Vital Signs

Vital signs include blood pressure, heart rate, respiratory rate and temperature and are taken at frequent intervals depending on patient condition.
