Welcome back to the Skills Lab. 😊 Today we set up oxygen safely. The green flowmeter on the wall is powerful — used well it rescues a patient, used carelessly it can harm one. We'll go in three easy steps: (A) match each delivery device to its flow range, (B) set the flowmeter for a real patient, and (C) make the right call for a COPD patient. Take your time — tap your way through.

Next door: a patient with COPD, SpO₂ 85% and a little breathless. What is the safest oxygen plan?

When you need a precise oxygen level

Read-only coaching — the deeper "why" behind the device you just set.
The FiO₂ from low-flow devices (cannula and simple/non-rebreather masks) is only approximate — it changes with each breath depending on how fast and deep the patient breathes.
For a COPD patient who needs an exact, controlled oxygen level, use a Venturi (air-entrainment) mask — it delivers a preset FiO₂ (24%, 28%, 31%, 35%, 40%, 50%), so you can hold the 88–92% target reliably instead of guessing.
Escalation: if a COPD patient stays hypoxemic, or the CO₂ climbs and they tire, despite controlled oxygen — check an arterial blood gas and escalate to non-invasive ventilation (BiPAP). The classic trigger is respiratory acidosis: pH < 7.35 with a rising PaCO₂ (> 45 mmHg) despite controlled O₂. Give oxygen, never withhold it — but titrate down and get the gas.

🏥 Your Skills Lab Room

Every device you master lights up here. (Building toward the full real-room photo Dr. Rob is sending.)
⚑ Build notes for Lucy/Pace & Dr. Rob · DRAFT pending clinical sign-off: when Dr. Rob sends the real hospital-room photo, we can map each device hot-spot onto it so tapping a device opens its skill module. The flow ranges and SpO₂ responses here are a teaching model, not a dosing tool — oxygen device and target always follow the provider's order and your facility's protocol.
