Dmitri Jessup: Acute respiratory failure

ENC-00125 · 49M · Cardiology · admitted Fri Nov 06, 2026 04:00 PM · discharged Mon Nov 09, 2026 02:18 PM · attending Dr. Cyrus Ellingham

Specificity gap Criteria met Open

Criteria support Acute respiratory failure with hypoxia (J96.01); no corresponding diagnosis is documented.

Documented vs supported

Documented
not documented
Criteria support
Acute respiratory failure with hypoxia · J96.01 Acute respiratory failure with hypoxia
Outcome
Hypoxaemia criterion met with a sign of respiratory distress
Rule
Acute hypoxic respiratory failure v2026.11-1
Published source
Merck Manual Professional Version: Acute Hypoxemic Respiratory Failure (AHRF), including ARDS (2026), Definition/evaluation: PaO2 <60 mmHg, PaO2/FiO2 <300, or SpO2 <88%, with dyspnea and tachypnea · source (checked 2026-11-14)
Contested
Organizations use different oxygen-saturation cut-offs (SpO2 <88%, <=90% or <91% on room air). This rule uses <88% (the source above) and a LOCAL respiratory-rate cut-off of 28/min as one sign of respiratory distress.

DOCUMENTATION QUERY (draft)
Title: Clarification request: respiratory documentation
Encounter: ENC-00125   Patient: Dmitri Jessup   To: Dr. Cyrus Ellingham

Clinical indicators from the health record:
- SpO2 86% on room air (2026-11-06 16:20) [vital VIT-012161]
- respiratory rate 33/min (2026-11-06 16:20) [vital VIT-012162]
- O2 4 L/min (nasal cannula) (2026-11-06 16:30) [vital VIT-012163]

Question:
Based on your clinical judgement and the indicators above, can the respiratory diagnosis being evaluated and treated be further specified?

Response options (select one or write your own):
( ) Acute respiratory failure with hypoxia
( ) Hypoxemia without respiratory failure
( ) Other (please specify): ____________
( ) Unable to determine

Please respond based on your independent clinical judgement. Any response, including "unable to determine", is acceptable. This query and your response are kept as part of the health record.
