Definition & Operational Usage of Suctioning
What Is Suctioning?
Suctioning is the airway management procedure of inserting a rigid (Yankauer) or flexible suction catheter connected to a vacuum pump (generating -80 to -300 mmHg) into the pharynx or endotracheal tube to clear blood, vomit, or secretions.
⚠️ Operational Safety Warning:Limit suctioning attempts to a maximum of 10-15 seconds in adults (5-10 seconds in pediatrics) to prevent severe hypoxemia and vagal bradycardia.
Why Suctioning Matters on the Fireground
Aspiration of stomach contents or blood causes severe hypoxia and fatal chemical pneumonitis. Clearing the airway with suction is mandatory before attempting bag-valve-mask ventilation or intubation.
Relevant NFPA Standards
- NREMT Standards: National Registry of Emergency Medical Technicians Practice Standards
- NFPA 455: Standard for Emergency Medical Services (EMS)
Field Procedures & Tactical Steps
- Connect rigid Yankauer suction tip to portable or fixed suction unit generating at least -300 mmHg vacuum.
- Insert catheter into oral cavity only as far as visible without applying suction.
- Cover suction control port with thumb and sweep catheter outward, suctioning on withdrawal.
- Limit suctioning attempt to 10-15 seconds maximum.
- Hyper-oxygenate patient with 100% O2 before and after suctioning attempts.
Common Context & Application
Performed during primary airway management on unresponsive patients, drowning victims, facial trauma, and cardiac arrest calls.
Frequently Asked Questions about Suctioning
What is the maximum recommended suction time for an adult patient?
Suctioning should be limited to 10 to 15 seconds per attempt because suctioning removes oxygen from the airway along with fluids.
What vacuum pressure should a portable EMS suction unit generate?
A portable EMS suction unit must be capable of generating a vacuum of at least -300 mmHg when the tube is clamped.
