HFNC immediately after planned extubation,
does it really help with Reduced reintubation within 72 hours versus conventional oxygen?
research showsThe grade is B. A seven-ICU Spanish trial analyzed all 527 participants. Reintubation within 72 hours occurred in 13/264 (4.9%) with HFNC versus 32/263 (12.2%) with conventional oxygen, an absolute difference of 7.2 percentage points (95% CI 2.5 to 12.2). The clinical event fell significantly, but there is no independent replication of the same low-risk, conventional-oxygen comparison; the analyst was masked, whereas treating staff and reintubation decision-makers were not, giving B with 72 points.

Useful facts when choosing a product
- HFNC delivers warmed and humidified gas at high flow through nasal cannulae.
- Verdict 2561 concerns low-risk patients, HFNC versus conventional oxygen, and 72 hours. Verdict 2543 is B with 72 points and concerns high-risk patients, NIV versus HFNC, and seven days.
- Fisher & Paykel supplied blenders to two of seven ICUs and was reported to have no other study role.

What the research actually shows
Hernández G, Vaquero C, González P and colleagues randomized 527 participants, 264 versus 263, and analyzed all of them. The paper described concealed allocation through a telephone call center and intention-to-treat analysis. The analyst was masked, whereas treating staff and reintubation decision-makers were not. The study reported no external funding; Fisher & Paykel supplied air-oxygen blenders to two ICUs with no other study role. The paper's 72-hour primary endpoint matched NCT01191489.
Why this is classified as B (72)
An all-participant multicenter trial reduced actual reintubation, but the exact low-risk conventional-oxygen comparison lacks independent replication; the analyst was masked, whereas treating staff and reintubation decision-makers were not, giving B with 72 points.
Counterpoint. B does not mean every extubated patient requires HFNC; the verdict is limited to 72-hour reintubation in low-risk adults.
Rejudgment record. Cross-check applied — We cross-checked allocation concealment, all 527 randomized participants, the registered 72-hour primary endpoint, event counts, masking, and device provision against the article and registry.
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I1 | Mixed funding sources |
| Effect size | E+ | Meets the clinically important threshold |
Stored derived and displayed grades match; this is not a current recalculation or validity check (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced 72-hour reintubation in low-risk adults | B | Rates were 4.9% versus 12.2%, with the full interval favoring HFNC. |
