On this card

A dense, field-kit ETT sizing card covering preterm through adult. Weights are printed in both pounds and kilograms on every pediatric row, so you can work from whichever number you actually have at the bedside or on scene. Built for ED and ICU nurses, paramedics, flight crews, and respiratory therapists — anyone who assists with or performs airway management and does not want to do unit conversions during an intubation.

Front

an 11-row pediatric ETT table from preterm to 14 years — weight in lb and kg, uncuffed and cuffed tube sizes, and depth-at-lip per row; a formulas panel (uncuffed age÷4 + 4, cuffed age÷4 + 3.5, depth = 3 × tube ID, neonate depth kg + 6); laryngoscope blade sizes by age; suction catheter, gastric tube, and stylet rules; and an amber FAILED AIRWAY strip — the reposition → bougie → size down → SGA → two-person BVM → surgical airway sequence, max 2 attempts per operator.

Back

adult sizing and depth-at-teeth for men and women with nasal, suction, and bougie rows; an LMA-by-weight table (sizes 1–6, kg and lb) paired with the LEMON difficult-airway screen; a tube-confirmation table (waveform EtCO₂, auscultation, depth check, CXR tip position, why misting is unreliable); an amber cuff-pressure strip (20–30 cmH₂O by manometer, with high/low consequences and the transport/altitude recheck); and a boxed DEPTH = 3 × TUBE ID rule. Rigid PVC, water-resistant, standard CR80 badge size in the tan field-kit colorway with dark olive-and-amber print. Punched badge-reel slot at the top — rides behind your ID on any reel or lanyard and survives the shift. Content is clinician-reviewed and uses textbook-standard values. Field reference only, not a protocol — always verify against your institution's policies.
