What are lung protective strategies?

Lung protection was based on a strategy of maintaining low inspiratory driving pressures, with lower tidal volumes versus (vs) traditional tidal volumes (4-6 vs 10-12 mL/kg) and preferential use of limited airway pressure over regulation, with the simultaneous circumvention of alveolar collapse through the use of high …

What does lung protective ventilation mean?

OVERVIEW. Protective lung ventilation is the current standard of care for mechanical ventilation. It is synonymous with low tidal volume ventilation (4-8 mL/kg) and often includes permissive hypercapnia.

What is the recommended strategy for ventilating patients with ARDS?

For mechanical ventilation specific settings are recommended: limitation of tidal volume (6 ml/kg predicted body weight), adequate high PEEP (>12 cmH2O), a recruitment manoeuvre in special situations, and a ‘balanced’ respiratory rate (20-30/min).

How do you do a lung recruitment maneuver?

METHODS

  1. Use pressure controlled ventilation.
  2. Set respiratory rate to zero and turn off apnoea alarm.
  3. increase PEEP to 40 cmH20 for 40 seconds.
  4. most recruitment occurs in the first 10s, with haemodynamic compromise occurring later.

What does Simv stand for?

Synchronized intermittent mandatory ventilation
Introduction. Synchronized intermittent mandatory ventilation (SIMV) is a type of volume control mode of ventilation. With this mode, the ventilator will deliver a mandatory (set) number of breaths with a set volume while at the same time allowing spontaneous breaths.

How do you prevent respiratory distress?

There’s no way to prevent ARDS completely. However, you may be able to lower your risk of ARDS by doing the following: Seek prompt medical assistance for any trauma, infection, or illness. If you smoke, consider stopping smoking cigarettes.

How can I improve my lung compliance?

By increasing the positive end-expiratory pressure (PEEP) of the air being delivered, we may be able to “force” some of the water out, thereby increasing the lung compliance making it easy to ventilate the lungs.

What is inspiratory hold maneuver?

The inspiratory hold manoeuvre abolishes the pressure contribution from the airway resistance and reveals the pressure in the alveoli.

What is optimal PEEP?

Best or optimal PEEP will be defined as the PEEP below which PaO2 /FIO2 falls by at least 20%. If at least 20% PaO2 /FIO2 decrement is not obtained, then PEEP that will result in the highest PaO2 will be selected. Other Name: PEEP determined by Best oxygenation approach.

What is the difference between SIMV and CMV?

Synchronized Intermittent Mandatory Ventilation (SIMV) The difference between the two modes only appears when the patient triggers additional spontaneous breaths. In the CMV mode, spontaneous and mandatory breaths are the same; but in the SIMV mode, different breath types are always used (Figure 5.1D).

What is the difference between ACV and SIMV?

Just as in AC mode, if the patient does not trigger a breath, the patient will receive a set volume/pressure breath, as in the first breath here. However in SIMV when a triggered breath is initiated the patient determines the volume, which may be smaller than the non triggered breath.
