0-188 |
Sentence |
denotes |
As critically ill patients are often found to form methemoglobin (MetHb) [8,9,10] and carboxyhemoglobin (COHb) [11,12], MetHb and COHb formation might also be relevant in case of COVID-19. |
| T21 |
189-305 |
Sentence |
denotes |
MetHb is formed when the ferrous iron (Fe2+) of the heme group of hemoglobin (Hb) is oxidized to ferric iron (Fe3+). |
| T22 |
306-361 |
Sentence |
denotes |
The ferric iron of MetHb is unable to bind oxygen (O2). |
| T23 |
362-491 |
Sentence |
denotes |
Thus, the O2 dissociation curve is left-shifted, making it more difficult to release O2 and to provide proper tissue oxygenation. |

492-578 |
Sentence |
denotes |
The formation of MetHb also results in less Hb available for O2 binding and transport. |
