Emergency suction equipment: barriers to use and effective interventions
BMJ Quality Improvement Reports
|January 7, 2016
Summary
Simple labels improved emergency suction usability. Staff successfully used equipment more often and faster after intervention, enhancing patient safety during critical events.
Area of Science:
- Medical device usability
- Patient safety interventions
- Healthcare quality improvement
Background:
- Emergency suction equipment failures are a known patient safety risk.
- Usability issues with cardiac arrest trolley suction hinder effective use.
- National Patient Safety Agency highlights failings in emergency suction.
Purpose of the Study:
- To improve the usability of emergency suction equipment on cardiac arrest trolleys.
- To simplify the operation of a complex suction activation process.
- To reduce delays and errors in emergency suctioning.
Main Methods:
- A randomized controlled trial was conducted across two wards.
- Simple, visible labels with prompts were introduced as an intervention.
- Staff (medical, nursing, allied health) timed suction activation in a simulated scenario.
Main Results:
- Post-intervention, 100% of staff successfully activated suction, compared to 50-60% previously.
- Mean activation time decreased from 43-50 seconds to 30 seconds.
- The intervention received strongly positive feedback from participants.
Conclusions:
- Simple, visible design interventions can significantly improve emergency equipment usability.
- Addressing poor equipment design enhances performance in critical, high-pressure situations.
- Standardizing intuitive designs can foster a culture of improved patient safety.

01:25Suctioning the Oropharyngeal Airway
1.4K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
