Lecture 10: Smoke and respiratory complications of poisoning Flashcards
1
Q
What 3 reasons can cause Asphyxiation
A
- Exclusion of O2 from air by inert gas
- Acute laryngeal oedema
- Interference with O2 transport by metabolic poisons
2
Q
What are the signs of acute respiratory failure (4)
A
- Decreased breathing rate
- Increased pCO2
- Decreased pO2
- Decreased pH
3
Q
What does hyperventilation lead to (3)
A
- respiratory alkalosis
- decreased pCO2
- increased pH
4
Q
What are 5 secondary respiratory complications
A
- progressive respiratory failure
- Acute respiratory distress syndrome
- Cardiogenic pulmonary oedema
- Respiratory depression leading to atelectasis and infection
- Aspiration of gastric contents
5
Q
What are the supportive care measures for respiratory complications (3)
A
- supplemental oxygen
- protect airway
- Endotracheal tube and mechanical ventilation
6
Q
What management would you use against Bronchoconstriction
A
- Beta2 agonists
7
Q
What management would you use against Acute pulmonary oedema
A
- Mechanical ventilation
- Peak expiratory end pressure (PEEP)
8
Q
What management would you use against Acute respiratory distress syndrome
A
- Mechanical ventilation
- Peak expiratory end pressure (PEEP)
9
Q
What management would you use against Bronchiolitis obliterans
A
Steroids
10
Q
Management of smoke inhalation (4)
