Airway care and oxygenation
8. P2. Pre-oxygenation
Type of patient
Amount of time a patient can maintain
Sa 02 > 90%
Healthy 70kg adult 8 minutes
Moderate ill adult 5 minutes
10Kg child 4 minutes
Obese adult 3 minutes
Very ill patient <2minutes
Time taken to desaturate from 90% to zero is very short. In the
healthy adult it is 120 seconds, and in a child it is only 45 seconds.
10. P4. Paralysis with Induction
Induction agent
Thiopental 3mg/kg IV
Fentanyl 2-3mcg/kg
Propofol 1.5mg/kg IV
Midazolam 0.2-0.3mg/kg
Ketamine 1.5mg/kg IV
Paralysis agent
Agent Dose Onset (sec) Duration (min)
Succinylcholine 1.5mg/kg IV 46sec 6-10 min
Rocuronium 0.1mg/kg IV 60-75sec 40-60 min
Vecuronium 0.01mg/kg 120-180sec 45-65 min
12. P6. Placement and Proof
• Intubation should be performed carefully and gently. The larynx is visualised
and the endotracheal tube placed. The stylet, if used, is then removed and
the cuff inflated.
