Table 3 Appropriate monitoring of Noninvasive Respiratory Support (NIRS)

From: Noninvasive respiratory support for COVID-19 patients: when, for whom, and how?

Appropriate Monitoring of Noninvasive Respiratory Support
1) Hourly lab assessment (for 3 h)
  a) ABG including PaO2, PaCO2, bicarbonate, lactate, and base excess
  b) PaO2/FiO2 (target PaO2/FiO2 > 300) [24, 50]
  c) Subjective improvement or worsening of dyspnea [4]
2) Continuous monitoring (for 3 h):
  a) Heart rate and respiratory rate trends [4, 24]
  b) Pulse oximetry and FiO2 requirement
  c) Tidal volume measurement if utilizing CPAP or NIV [21, 43, 54]
