Pneumothorax (PSP / SSP / tension / traumatic)
Encounter flow
12/12 authoredCanonical 12-phase frame with authored status for this dossier.
Frame
Confirm pneumothorax type — primary spontaneous (PSP) vs secondary spontaneous (SSP) vs tension vs traumatic vs iatrogenic vs catamenial
Type/etiology classified
Patient inputs (13)
PSP (tall thin young) vs SSP (older with COPD) phenotype
Hypotension flags tension PTX
Tachycardia in tension/large PTX
Severity of impairment + drainage threshold
Tachypnea + work-of-breathing severity
Distinguishes PSP from SSP (COPD, CF, ILD, lung cancer)
Iatrogenic vs traumatic — drives chest tube indication
Upright PA CXR for size estimation
Occult PTX, blebs/bullae mapping, surgical planning
PSP male predominance + catamenial PTX in females
Vent-associated PTX requires chest tube
Bleeding risk for procedure planning
Bedside diagnosis (loss of sliding, lung point)

Assessment
**Pneumothorax (PSP / SSP / tension / traumatic)** (pulm.pneumothorax.core.v1). Phenotype framing: PSP vs SSP vs tension vs traumatic vs iatrogenic vs catamenial; consider PE / MI / pneumonia / aortic dissection Scope: Confirm pneumothorax type — primary spontaneous (PSP) vs secondary spontaneous (SSP) vs tension vs traumatic vs iatrogenic vs catamenial No severity triggers fired against current inputs.
Plan
Regimen axis: **BTS 2023 + ERS/ESTS 2024 — drainage strategy by type, size, symptoms** — step "Tension pneumothorax — emergent decompression". 1. oxygen High-flow O2 15 L/min via NRB inhaled continuous (oxygen, first line) — Accelerates resorption (4× rate vs RA) and treats hypoxia Setting playbook (ed) — Identify and decompress tension PTX, classify type/size, choose drainage modality (observe / aspirate / pigtail / large-bore), arrange disposition 2. oxygen High-flow 10–15 L/min NRB inhaled continuous — Any pneumothorax (Accelerates pleural air absorption (4× vs RA); also treats hypoxia) 3. acetaminophen + ibuprofen APAP 1 g + ibuprofen 400 mg PO/IV q6h scheduled — Pain (Multimodal analgesia) 4. lidocaine local + procedural sedation (fentanyl + midazolam) Lido 1% 10–20 mL; fent 50–100 µg + midaz 1–2 mg IV SC + IV pre-procedure — Aspiration / chest tube (Procedural anesthesia + sedation; capnography) 5. cefazolin 2 g IV × 1 IV single dose — Traumatic chest tube (EAST trauma single-dose prophylaxis) 6. oxycodone (rescue) 5 mg PO q4h PRN PO q4h PRN — Breakthrough pain (Limit duration) Non-pharmacologic actions: - Tension PTX → immediate needle decompression: 4–5th ICS anterior axillary line OR 2nd ICS midclavicular (adult finger thoracostomy alternative); follow with chest tube - Aspiration: 14–16 G IV cannula 2nd ICS MCL or 4–5th ICS AAL; aspirate up to 2.5 L - Pigtail / small-bore chest tube (8–14 Fr) under US guidance — ambulatory candidacy if PSP no air leak - Large-bore chest tube (24–28 Fr) for SSP / hemopneumothorax / vent-associated - Lung ultrasound for diagnosis when unstable - Avoid positive-pressure ventilation if at all possible until decompressed AVOID / contraindication checks: - NSAID avoid if AKI GI bleed or recent anastomosis (BTS 2023) - Opioid minimise duration screen for OUD (ACCP 2001) - Procedural sedation capnography required (BTS 2023) - Talc use graded only avoid ungraded ARDS risk (ERS/ESTS 2024) - Scuba diving lifetime contraindication unless bilateral surgical pleurectomy (BTS 2023 Roberts) - High flow oxygen titrate to 88 92% if COPD CO2 retainer SSP (Austin 2010; BTS 2023) - Do not observe or aspirate a ventilated or tension PTX go straight to chest tube (BTS 2023)
Monitoring
Regimen monitoring: - serial CXR every 6 to 24h until resolved (BTS 2023) - air leak assessment q shift (BTS 2023) - pain score q shift (BTS 2023) - drain output q shift (BTS 2023) - aspirate volume documented at aspiration max 2.5 L (BTS 2023) - CXR at 2 to 4 weeks post discharge (BTS 2023 Roberts) - aviation advice no flight for 1 week post resolution (BTS 2023) - lifetime diving contraindication documented (BTS 2023) Setting (ed) monitoring: - Serial CXR or US q4-6 h initially then daily (BTS 2023) - Pulse oximetry continuous (BTS 2023) - Air leak (bubbling) assessment at chest drain (BTS 2023) - Drain output trend (BTS 2023) Follow-up plan: CXR at 2–4 weeks; aviation 1 week post-resolution; absolute lifelong contraindication to scuba diving (BTS); smoking cessation; surgical referral if recurrent; advise re: future PTX symptoms - Close-out criterion: Recurrence-prevention plan + surgical consultation completed if criteria met Monitoring phase: Serial CXR / US, drain output and air leak trend, pain control, smoking cessation counselling; aviation/diving counselling pre-discharge
Disposition
Current setting: ed — Identify and decompress tension PTX, classify type/size, choose drainage modality (observe / aspirate / pigtail / large-bore), arrange disposition Disposition criteria: - Discharge with safety-net (PSP Trial pathway Brown 2020): minimally symptomatic small PSP, social support, can return for 24-h CXR, return precautions reviewed - Ambulatory pigtail (RAMPP pathway Hallifax 2020): PSP, no air leak after pigtail placement, Heimlich valve, follow-up in 2-7 d - Admit ward: requires chest tube + observation (BTS 2023) - Admit ICU: SSP with respiratory failure, vent-associated PTX, hemopneumothorax (BTS 2023) Escalation triggers (move to higher acuity): - Recurrent tension despite needle decompression → finger thoracostomy + larger tube (ATLS 2018) - SSP with respiratory failure → ICU + chest tube (BTS 2023) - Bilateral PTX → urgent surgical referral (ERS/ESTS 2024) - Hemopneumothorax with shock → trauma activation (ATLS 2018)
