1.
1 ATA is equal to what? (2 possible answers): 760 mmHG or pressure at sea level
2.
Are there any side effects or adverse reactions to HBOT?: Yes, several
3.
Can HBOT revive dead brain tissue?: No
4.
Complete: At 2 ATA there is a ______ increase in O2 tension in the blood: 10-fold
5.
Complete: HBOT is not appropriate or contraindicated in cases of undrained __________ or untreated ___________, pts who are
undergoing _____ or _______ therapy,
pressure-sensitive ________ _________ _______, and certain anti-neoplastic ____________: undrained hemothorax or untreated pneumothorax
undergoing chemo or radiation therapy
pressure-sensitive implanted medical device
certain antineoplastic antibiotis
6.
Complete: HBOT is used in cases of ___or___ embolisms, carbon______ ______, thermal_____, refractory _________, delayed ______ injury, compromised ____ _____/______, wound healing, complex _____ _____ syndrome, Fibromyalgia, ______ pain ________, _________ and cluster _________, and _________ leg pain.: Air or gas, carbon monoxide poisoning, thermal burns, refractory osteomyelitis, delayed radiation injury, compromised skin graft/ flaps, complex regional pain syndrome, myofascial pain syndrome, migraine and cluster headaches, and ischemic leg pain
7.
Complete: HBOT should administered with caution to patients with COPD or asthma, _______ disorders, claustrophobia, chronic ______ or upper _______ ________, fever and/or dehydration, or a history of spontaneous ____________: COPD or asthma, seizure disorders, chronic sinusitis or upper respiratory infection, spontaneous pneumothorax
8.
How can HBOT help a CVA patient?: by improving ischemic penumbra (an area of moderately ischemic brain tissue surrounding an area of more severe ischemia. Theoretically, blood flow to this area may be enhanced in order to prevent the spread of a cerebral infarction); cannot resurrect dead brain tissue
9.
In addition to ↑ O2 delivery, ↑new blood vessel formation, and elimination of toxic substances what other proposed effects are there of HBOT?: Reduction/elimination of obstruction of gas bubbles and ↑natural activity of osteoclasts/blasts.
10.
Is HOBT appropriate for divers who've surfaced too quickly?: Yes
11.
T/F While it is proposed that HBOT can improve infection control it cannot preserve damaged tissue.: False, it does both
12.
T/F: ↑Cardiovascular afterload due to peripheral vasoconstriction is a possible side effect of HBOT.: True
13.
T/F: Oxygen toxicity that can effect renal, PNS, and CNS functioning is a potential side effect of HBOT.: False. Toxicicty effecting CNS, pulmonary, and ocular function are possible, not renal or PNS functioning
14.
T/F: Similar to flying, the inner ear, sinuses, dental, and pulmonary tissues are safe from potential barotrauma.: False, similar to flying, these areas are potentially at risk for barotrauma.
15.
There are 7 ways that HBOT speeds wound healing, what are they?: Saturation of blood w O2 forcing it into wound tissue; promoting new growth of blood vessels; hindering bacteria growth; enhancing immune function; reducing limbs swelling; neutralizing toxins; enhancing antibiotic uptake
16.
Types of Chambers: Monoplace ~ 22 inches in diameter
Multiplace - can usually accommodate 12 patients
17.
What is Hyperbaric Oxygen Therapy?: 100% Oxygen delivered in a pressurized chamber -pressure greater that 1 absolute atmosphere (ATA)
18.
What is the physiological effect of HBOT in a CVA?: Improves reduced O2 flow to areas of the brain that are lacking blood flow but are still viable (the penumbra)
19.
What is the typical dosage of pressure used in HBOT?: 2-3 ATAs x 30-120 min
20.
What neurological pathologies are also an indication for HBOT?: CVA, CP*
*please correct if wrong
21.
You are treating a patient with a diabetic ulcer on their foot. The patient reports that they've just taken a dose of insulin. Is HBOT appropriate?: No, although HBOT is indicated for wound healing it may cause hypoglycemia which may exacerbate low blood sugar levels in a pt with DM following an insulin dose.
