2.03.E – Simple Mask, Venturi Mask, Pulse Oxymetry, Humidification

Equipment for this station: - Oxygen system: Oxygen tank, regulator - Simple Mask, Venturi Mask, Pulse Oxymeter, humidifier - ET3 System - EMT manikin with arms for SPO2 station - Little Anne or other quality manikin for mask stations

Precautions: Do not let the station deteriorate into chatter. Continue rotating them through assemblies until time is up.

Objectives: Demonstrate use of pulse oximetry. (pp 334–335, Skill Drill 9-1)

Demonstrate the use of a Venturi and Simple Mask in providing supplemental oxygen therapy to patients. (pp 352–353)

Demonstrate the use of a humidifier in providing supplemental oxygen therapy to patients. (p 353)

Setup: Set up the manikin in the center of your space and have the students huddle around to see your demonstration.

Instructions to be read to students: “I am going to demonstrate use of these three devices. You may not carry them all in your ambulance if you work for a 911 service, but you will occasionally encounter them if you do medical transportation ”

Please note the following:

1. Demonstrate use of each device. Do not take more than 5 minutes. Venturi mask will be the most involved.

2. Discuss that in long transports (particularly in medical transportation of patients who are on oxygen for days at a time) humidification of oxygen keeps mucous membranes from drying. While it may be very common in 911 service, oxygen humidification is something they shold be familiar with. 3. Discuss possible pitfalls of pulse oximetry such as BP cuff use on that arm, poor distal perfusion, dirty hands, nail polish (questionable), etc.

4. Remind students CO poisoning can be misleading with pulse oximetry

5. You should absolutely be using ET3 for the SPO2 station so students can see the pulse oximetry readings fluctuate
