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.
