Classification of Ventilation

1.   Mechanical ventilation 

1. Positive Pressure Ventilation (PPV)

A. Invasive Ventilation/ Mechanical ventilation 

Via Endotracheal Intubation or Tracheostomy tube


B. Non-invasive Ventilation (NIV)

Via face mask or nasal prong

1. CPAP (Continuous positive airway pressure)

2. BiPAP (Bilevel positive airway pressure)

3. Automatic positive airway pressure (APAP)



2. Negative Pressure Ventilation 


B. Bag Valve mask Ventilation/Ambu bag/self-inflating bag

Positive Pressure Ventilation 



Types of Positive Pressure Ventilation

2. Time cycled ventilators/Flow-cycled ventilation

Used in newborns and infants


3. Volume cycled ventilators

a. Control mode

b. Assist mode

c. Assist/control mode

d. Intermittent mandatory ventilator (IMV)

e. SIMV (Synchronized intermittent mandatory ventilator)


Types of Negative Pressure Ventilation

1. Iron lung (tank ventilator)

2. Body wrap (Pneumowrap)

3. Chest cuirass (Tortoise shell)
