CHT Patient Care and Safety in the Hyperbaric Environment 1 — Questions and Answers
Question 1: What is a critical safety rule for patients before entering a hyperbaric chamber?
- Wear cotton clothes
- Apply lotion before entering
- Keep cell phones on hand
- Remove all flammable items (Correct answer)
Correct answer: Remove all flammable items
Hyperbaric chambers operate with high concentrations of oxygen, which significantly increases the risk of fire. Removing all flammable items, including synthetic clothing, electronic devices, and petroleum-based products, is a critical safety rule. This measure is essential to prevent ignition and ensure patient safety in the oxygen-rich environment of the chamber, where even a small spark can lead to a catastrophic fire.
Question 2: What should a technologist monitor continuously during HBOT?
- Patient’s mood
- Oxygen tank weight
- Vital signs (Correct answer)
- Chamber color
Correct answer: Vital signs
Continuous monitoring of vital signs (e.g., heart rate, blood pressure, respiratory rate, and oxygen saturation) is essential during HBOT. This allows technologists to assess the patient's physiological response to the increased pressure and oxygen levels in real-time. Prompt detection of any adverse reactions or complications, such as changes in cardiac function or respiratory distress, enables immediate intervention and ensures patient safety throughout the treatment.
Question 3: Which patient condition would require special attention before hyperbaric treatment?
- Muscle soreness
- Sinus congestion (Correct answer)
- Mild headache
- Joint stiffness
Correct answer: Sinus congestion
Sinus congestion requires special attention before hyperbaric treatment because trapped air within congested sinuses can lead to severe pain and barotrauma during changes in chamber pressure. Patients must be able to equalize pressure in their sinuses and ears to prevent injury. Significant congestion may necessitate deferring treatment or using decongestants to ensure safe pressure equalization and prevent complications.
Question 4: How should staff respond if a patient experiences ear discomfort during descent?
- Continue descent quickly
- Ignore the complaint
- Stop the treatment immediately
- Pause or slow descent (Correct answer)
Correct answer: Pause or slow descent
Ear discomfort during descent indicates a failure to equalize pressure in the middle ear, which can lead to barotrauma (pressure injury). The appropriate response is to pause or slow the descent, giving the patient more time to perform equalization maneuvers like swallowing or the Valsalva maneuver. This action helps prevent potential damage to the eardrum or middle ear structures and ensures patient comfort.
Question 5: What is the best way to reduce the risk of fire in a hyperbaric chamber?
- Spraying perfume before treatment
- Using battery-powered devices
- Eliminating ignition sources (Correct answer)
- Allowing synthetic clothing
Correct answer: Eliminating ignition sources
Hyperbaric chambers are oxygen-enriched environments, making them highly susceptible to fire. The most effective way to reduce this risk is by rigorously eliminating all potential ignition sources. This includes prohibiting electronic devices, synthetic clothing, petroleum-based products, and ensuring proper grounding to prevent static electricity, thereby creating a safe treatment environment.
Question 6: What is the recommended action if a patient becomes claustrophobic during treatment?
- Ignore the anxiety
- Increase chamber pressure
- Pause treatment and provide reassurance (Correct answer)
- Turn off chamber lighting
Correct answer: Pause treatment and provide reassurance
Claustrophobia can be a significant challenge for patients in the confined space of a hyperbaric chamber. If a patient experiences claustrophobia, the recommended action is to pause the treatment and provide reassurance. This allows the patient to regain composure, helps alleviate their anxiety, and ensures their comfort and ability to safely continue the therapy, prioritizing their well-being.
