Study Notes
Indications for Suctioning
- Establish airway patency
- Remove secretions (saliva, vomit, blood)
- Obtain a sample
- Cell salvage (blood recycle)
Essential Parts of a Suction Apparatus
- Source of vacuum
- Reservoir
- Delivery tubing (may include nozzle or catheter)
Refinements of a Suction Apparatus
- Cut-off valve
- Bacterial filter
- Vacuum control valve
- Vacuum gauge
- Stop valve
Efficiency of a Suction Apparatus
- Dependent on displacement (volume of air moved at atmospheric pressure, expressed in liters/minute)
- Dependent on degree of negative (sub-atmospheric) pressure produced by the pump
- Dependent on time taken to achieve negative pressure
- Dependent on length and diameter of the delivery tube
Test your knowledge on the indication and essential components of a suction apparatus in medical settings. Learn about the importance of suctioning in establishing airway patency, removing secretions, obtaining samples, and cell salvage. Explore the key elements and refinements of a suction apparatus.
