Table 1 Definition of postextubation acute respiratory failure

From: Physiological impact of high-flow nasal cannula therapy on postextubation acute respiratory failure after pediatric cardiac surgery: a prospective observational study

Tachypnea

RR >50 breaths per minute (<1 year old)

RR >40 breaths per minute (1–4 year old)

Hypoxemia

SaO2 <92% (total repair)

SaO2 <75% (palliative operation)

Hypercapnia

PaCO2 >50 mmHg

Increased work of breathing

Using accessory respiratory muscle

  1. Postextubation acute respiratory failure is defined by at least one of the criteria
  2. RR respiratory rate, PaCO 2 partial pressure of arterial carbon dioxide
