We are using HFNC when saturation of oxygen falls despite using Re-breather mask to supply upto 15L oxygen. Then we use HFNC and if it fails then we use Bi-PAP or C-PAP. So why not C-PAP/Bi-PAP early? What do you say?
Hello sir.
HFNC helps to increase FiO2, reduces anatomical dead spaces and increase functional residual volume. It is also more comfortable for patient than CPAP.
CPAP helps to prevent alveolar collapse by maintaining PEEP.
In Covid 19 hypoxia, patient experiences an abrupt fall in O2 saturation which demands a vigorous treatment protocol. Hence HFNC is used initially to prevent the fatal consequences of COVID 19 hypoxia.
CPAP may not be considered as superior or equivalent to HFNC, however, it can be used for those patients who can not tolerate HFNC.
