Indications for Mechanical Ventilation
Modes of Ventilation
Reading a Ventilator Waveform
1. Determine the CPAP Level: This is your baseline pressure before a breath is taken
2. Is the patient triggering breaths? Identify if the patient is overbreathing the vent. Check the set respiratory rate and the actual, and identify any negative deflections in pressure which indicates a patient is attempting to take a breath.
3. What shape is the pressure wave?
4. Is the patient gas trapping?
5. Is the patient synchronizing with the ventilator? If the patient is attempting to take breaths and the vent is not triggering, the sensitivity will need to be decreased until the patient is no longer fighting the ventilator.
