Table 2. Characteristics of COVID-19 pneumonia (CARDS) Type L and H.
| COVID-19 Pneumonia, Type L | Property | COVID-19 Pneumonia, Type H |
|---|---|---|
| Low | High | |
| Normal-to-high | Low | |
| Normal | Decreased | |
| Low ventilation-to-perfusion (V/Q) ratio due to vasoplegia and loss of hypoxic vasoconstriction | Right-to-left shunt due to perfusion of non-aerated regions affected by edema and high pressures | |
| Normal-to-low | High | |
| Low with sparse non-aerated regions | Increased with more non-aerated regions | |
| Limited interstitial ground-glass opacities along subpleural planes and lung fissures | Extensive consolidations |
