The Respiratory System Module 11 & 12

Yes the Respiratory System gets two modules. This is a big topic and I am amazed that it can be done in just two modules.


First the Respiratory system and general principles discuses the mechanics of the respiratory system and the equipment we use in nursing. There is an amazing array of equipment from nasal cannulas, masks, intubation tubes, tracheotomy tubes, and chest tube with water seal drainage. The basic principles that I learned and used several years ago while working with critically ill patients still applies. The equipment may look a little different. The newer models are improved and are less time consuming to set up.

I like the new patient care process for helping the patient clear secretions with the use of suctioning. Of course, I am thinking about the patient on mechanical ventilators. The patient is hyperventilated for 1 minute or uses 100% oxygen for a minute. The suction catheter is attached to the side of the endotracheal tube or tracheotomy tube. The suction catheter is enclosed in a sterile plastic sleeve. The catheter is fed through the plastic sleeve and withdrawn without the catheter ever being exposed outside the sterile environment. I actually used this device before I left nursing. It is nice because a closed system is maintained and the patient is not removed from the ventilator for the suctioning procedure. This procedure is less invasive and less traumatic for the patient.

The AHEC offered a hands-on class on respiratory equipment and patient care before we started our practicum. The class cost extra but was well worth the extra expense. Students played with the equipment and received instruction in a safe environment. We asked questions and practiced on life like dummies that came complete with a respiratory system. If you are a returning nurse and you have the opportunity to take more classes I would definitely recommend the class on respiratory care delivery and equipment.

Module 12 will be discussed in the next blog.
