Question 65 · LEK · Carbon monoxide poisoning
Indicate the true statements regarding hyperbaric oxygen therapy (HBOT):
1) in the case of CO intoxication recommended therapy involves putting the patient under the pressure of 4.0 atm during for minutes;
2) “golden hour” for HBOT in severe CO intoxication is 6h;
3) one of indications for HBOT is COHb concentration over 25%;
4) HBOT shifts the oxyhemoglobin dissociation curve to the left;
5) HBO is known to be safe both for pregnant women and the foetus.
The correct answer is:
2) “golden hour” for HBOT in severe CO intoxication is 6h;
3) one of indications for HBOT is COHb concentration over 25%;
4) HBOT shifts the oxyhemoglobin dissociation curve to the left;
5) HBO is known to be safe both for pregnant women and the foetus.
The correct answer is:
- A. 1,2.
- B. 1,3.
- C. 2,3.
- D. 4,5.
- E. 1,5.
Hint
Recall the usual chamber pressure used for CO poisoning and whether hyperbaric oxygen really shifts the oxyhaemoglobin dissociation curve.
