KETTERING (SPECIAL PROCEDURES)

CORRECT SOLUTIONS.

Explain the purpose of Hyperbaric Oxygen Therapy (HBO) - correct answer- - Means of increasing the PO₂ by increasing the barometric pressure

List the diseases/disorders that can be treated with hyperbaric O₂ therapy - correct answer- - CO poisoning

• Decompression sickness (bends)
• Tissue transplants/graphs
• Anaerobic infections (gas gangrene)

What are the pressures in which HBO therapy is conducted? - correct answer- - Most HBO therapy is conducted at pressures between 2-3 atmosphere pressure absolute (ATA).

a) Typical chamber can provide pressure between 2-6 ATA.

Describe how the respiratory therapist would administer oxygen to a patient receiving hyperbaric oxygen therapy - correct answer- - It is administered by mask or through the chamber at

100% 1 / 3

Describe the purpose of utilizing Helium/Oxygen therapy for patients who have increased work of breathing (WOB) - correct answer- - Decreases the patient's WOB by delivering low density gas (most important property) that can easily maneuver around obstructions

State the indications of Helium/Oxygen therapy - correct answer- - Post extubation stridor

• Severe asthma/status asthmaticus
• Obstructive tumors
• Foreign object aspiration
• Partial vocal cord paralysis

List the two He/O₂ mixtures that are available - correct answer-

• 80% He/20% O₂ (most used)
• 70% He/30% O₂

What type of oxygen administration device is used to deliver Helium/Oxygen therapy? - correct answer- - Non-rebreathing mask

What would the actual flow rate be if a 70/30 heliox mixture is used with an oxygen flowmeter set at a rate of 8 L/min? - correct answer- - Actual Flow= indicated flow × factor

Factors:

a) 80/20 mixture: 1.8 (or use 2)

b) 70/30 mixture: 1.6

Ex: Actual Flow = indicated flow × factor

Actual flow = 8 L/min × 1.6 Actual flow = 12.8 L/min

Describe the physiologic effects of Inhaled Nitric Oxide (iNO) on the pulmonary system - correct answer- -Inhaled Nitric Oxide (iNO) acts as a potent pulmonary vasodilator, which improves pulmonary blood flow and PaO₂, but does not affect systemic blood pressure.

List the 4 indications for inhaled nitric oxide therapy - correct answer- - Primary pulmonary hypertension

• Refractory hypoxemia related to increased pulmonary artery

pressure (PAP)

• Increased pulmonary vascular resistance (PVR)
