Chronic respiratory failure check what needs to be done
Laboratory checks respiratory failure can objectively reflect the nature and extent of the guidance of oxygen therapy, mechanical ventilation various parameters of the regulation, and correct pH balance and electrolytes are important values.

1. PaO2 (PaO2): PaO2 less than 8 kPa (60mmHg) as the diagnosis of respiratory failure indicators.

Second, the arterial blood oxygen saturation (SaO2): severe respiratory failure in the rescue, with the pulse of oxygen saturation detector to help evaluate the degree missing O2.

3, arterial blood oxygen content (CaO2).

4. PaCO2: PaCO2> 6.65kPa (50mmHg) as an indicator of respiratory failure.

5, pH value: less than 7.35 for decompensated acidosis, higher than the 7.45 for decompensated alkalosis,

6, the combination of carbon dioxide (CO2CP).
