Question 1

What are the types of Non Invasive ventilation?

Answer 1

CPAP

BIPAP

Question 2

What is HFO?

Answer 2

High flow oxygen is used in type 1 RF (Without hypercapnia) delivered through Nasal cannulae

reduces work of breathing by improving gaseous exchange

Question 3

What is CPAP?

Answer 3

Used in Type 1 Respiratory Failure without Hypercapnia

Prevents alveolar collapse by giving Constant Positive Alveolar Pressure

Improves oxygen delivery to pulmonary capillaries

Question 4

What is BIPAP?

Answer 4

Bilevel Positive Airway Pressure

Used in Type 2 respiratory failure (Hypoxia and Hypercapnia)

Delivers IPAP and EPAP (Different pressures for inspiration and expiration)

Question 5

What is CPAP used to treat?

Answer 5

Pneumonia, ARDS, Pulmonary fibrosis

Helps to avoid intubation and mechanical ventilation

Question 6

What is BIPAP Used to treat?

Answer 6

COPD, Covid-19

pre-exisiting lung injury can be worsened by use of BIPAP

Question 7

How does CPAP work?

Answer 7

Increases the alveolar-cappilary refill time so more carbon dioxide-oxygen perfusion

Treats collapsed alveoli
