Procedural Skills for Medical Students
Objectives:
1.
Learners should be able to verbalize the indications and proper use for each airway adjunct.
2.
Learners should be able to demonstrate use of the basic airway adjuncts on the HPS.
3.
Learners should be able to effectively ventilate HPS with self-inflating bag & mask.
Material to review prior to lab: Video on Pulse Oximetry and
Positive-Pressure Ventilation (need access to New England
Journal of Medicine, available to students through the University of Arizona Health
Sciences Library)
Indications:
1.
Hypoxemia with or without CO
2
retention
2.
Apnea
3.
Airway obstruction
4.
Cardiopulmonary arrest
5.
Increased work of breathing or inadequate respiratory effort
6.
Increased myocardial work
7.
Pulmonary hypertension
Contraindications:
1.
Careful administration of oxygen in patients with chronic carbon dioxide retention (i.e.
COPD), as the increased partial pressure of oxygen in the arterial blood may depress their respiratory drive.
2.
Bag & Mask ventilation – severe facial trauma, foreign material in airway, complete irreversible airway obstruction.
Equipment: HPS, nasal cannula, facemask, non-rebreather, NPA/OPA, self-inflating bag and mask, and oxygen source
Instructional Procedure & Endpoints:
1.
Learners will be oriented to trainer and equipment in ASTEC.
2.
ASTEC staff will demonstrate the use of each airway adjunct interactively by having the learner place the adjunct on the HPS and answer questions relating to the delivery of each device.
3.
No formal evaluation will be completed; learners are expected to participate actively in discussion.
