Read the first 7 Patient Care & Monitoring in Hyperbaric Settings flashcards as text

  1. Which of the following patients would require the MOST careful monitoring for pulmonary oxygen toxicity during a prolonged HBO treatment course?

    Answer: A 60-year-old receiving daily HBO for 60 consecutive days for radiation tissue damage

    Pulmonary oxygen toxicity (Lorraine Smith effect) is associated with cumulative oxygen exposure; patients receiving many consecutive treatments are at highest risk.

  2. What is the MOST appropriate patient position during HBO therapy for a patient with a suspected air embolism?

    Answer: Left lateral decubitus (Durant's position) with Trendelenburg

    Left lateral decubitus with Trendelenburg positioning helps trap air in the right ventricle and prevents it from entering the pulmonary artery.

  3. A patient on anticoagulant therapy is scheduled for HBO treatment. Which assessment finding would be MOST important to document before initiating therapy?

    Answer: Recent INR or coagulation study results

    Anticoagulated patients have increased bleeding risk; current coagulation values (INR/PT) must be reviewed and documented before HBO therapy.

  4. During a hyperbaric treatment, a patient's SpO2 reading drops to 88% on the transcutaneous monitor. What should the CHT consider FIRST?

    Answer: Check the sensor placement and consider probe artifact before clinical intervention

    Transcutaneous monitors can give artifact readings due to sensor placement, movement, or perfusion issues; verify sensor placement before escalating care.

  5. Which of the following is a recognized CONTRAINDICATION to hyperbaric oxygen therapy?

    Answer: Untreated pneumothorax

    An untreated pneumothorax is an absolute contraindication to HBO because pressurization can convert it to a tension pneumothorax.

  6. A patient receiving HBO for a non-healing wound reports new chest tightness and shortness of breath after the 30th treatment. This presentation is MOST consistent with:

    Answer: Pulmonary oxygen toxicity

    Chest tightness and dyspnea after many HBO sessions suggests pulmonary oxygen toxicity (Lorraine Smith effect) from cumulative oxygen exposure.

  7. When preparing a critically ill ICU patient for hyperbaric oxygen therapy, which piece of equipment requires SPECIAL consideration before chamber entry?

    Answer: Cuffed endotracheal tube with air-filled cuff

    Air-filled cuffs compress under pressure and expand during decompression, risking extubation or tracheal damage; cuffs must be filled with sterile water or saline.
