Study Notes

Hyperbaric Chamber Oxygenation

  • Carbon monoxide poisoning can cause tissue hypoxia, which can lead to respiratory depression, stridor or wheeze, confusion, coma, headaches, and muscular weakness
  • Symptoms may also include skin discoloration, increased respiratory rate and pulse rate, and wheezing due to inflammatory response
  • Diagnostic tests include arterial blood samples to measure carboxyhemoglobin levels, which is normally 12% but can be greater than 30-40% in severe cases

Management of Carbon Monoxide Poisoning

  • Hyperbaric chamber oxygenation is the treatment of choice for decompression sickness, high-altitude sickness, and diabetic foot
  • Monitor ECG and treat dysrhythmias, correct acid-base and electrolyte abnormalities, and observe patients closely for psychoses, spastic paralysis, visual disturbances, and cerebral anoxia

Airway Obstruction Management

  • Partial airway obstruction with good air exchange: patient is responsive, can cough forcefully with wheezing between coughs
  • Partial airway obstruction with poor air exchange: patient has a weak, ineffective cough, high-pitched noise while inhaling, and increased respiratory difficulty
  • Complete airway obstruction: victim is unable to speak, breathe or cough, and may clutch the neck; requires immediate intervention to prevent brain damage or death

Ventilation Techniques

  • Mouth-to-Mouth resuscitation: used when impossible to ventilate the victim's mouth, or when the mouth is seriously injured
  • Mouth-to-Nose resuscitation: recommended when mouth-to-mouth is difficult to achieve
  • Mouth-to-Infant resuscitation: used for infants, placing the rescuer's mouth over the infant's mouth and nose to create a seal
  • Mouth-to-Stoma resuscitation: used for patients with a stoma, connecting the trachea directly to the front of the neck
  • Big Valve Mask ventilation: a common method of ventilation in acute hospital setups, using a hand-operated device with a self-inflating bag, one-way valve, facemask, and oxygen reservoir.
