Olfactory receptor neurons (ORNs) convert odor signals first into a receptor current that in turn triggers action potentials that are conveyed to second order neurons in the olfactory bulb. Here we describe the suction pipette technique to record simultaneously the odorant-induced receptor current and action potentials from mouse ORNs.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA In contrast to the production of cars or toasters, where millions of identical copies are made and extensive prototype testing is possible, each civil engineering structure is unique and very expensive to reproduce (Fig.1). Therefore, civil engineers must extensively rely on analytical modeling to design their structures. These models are simplified abstractions of reality and are used to...

Suctioning the Oropharyngeal Airway

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...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia. Equipment Required Suction machine with adjustable pressure settings Sterile suction catheters (appropriate size for the patient) Sterile gloves Sterile saline or water (for irrigation or lubrication) Water-soluble lubricant Personal protective...
FAQs
The system creates lower pressure in the catheter and collection pathway than at the treatment site. This pressure gradient encourages fluids, secretions, blood, or other unwanted material to move through the tubing rather than remain pooled. Maintaining a suitable gradient supports continuous removal, while excessive suction can increase the risk of tissue trauma and requires careful control.
Suction pressure determines how strongly material is drawn toward the collection system, whereas catheter placement determines whether the device reaches the material without unnecessarily contacting vulnerable tissue. Effective treatment therefore depends on balancing access and pressure. Poor placement may leave fluid behind or cause trauma, while appropriate positioning supports a clearer treatment field and safer fluid removal.
Regulated suction helps maintain a controlled pressure difference instead of allowing removal forces to vary unpredictably. That control can reduce pooling while limiting unnecessary stress on tissues near the catheter or device. In clinical practice, pressure regulation must be considered together with placement and the condition of the treatment site, because effective clearance should not compromise tissue protection.
A typical setup includes a catheter or suction device positioned at the treatment site, tubing that connects the device to a collection system, and a source of regulated negative pressure. Each component contributes to performance: placement enables access, tubing provides the passageway, and the collection system receives removed material. Their arrangement must support continuous flow and protect the site.
Application begins with selecting an appropriate catheter or suction device for the treatment site, positioning it to access unwanted material, and connecting it through tubing to the collection system. Clinicians then establish regulated suction and monitor removal while protecting nearby tissue. The exact workflow depends on whether the method is used for airway care, surgery, or wound management.
Clinicians may use this approach when accumulated material interferes with care or obscures a treatment site. Supported settings include airway care, surgical procedures, and wound management. In each context, the device and placement must match the site, while controlled suction helps limit pooling and maintain a clearer field for ongoing treatment.
Assessment can focus on whether unwanted fluids, secretions, blood, or other material are being removed from the intended site and whether pooling has decreased. Clinicians should also consider the condition of surrounding tissue and the position of the catheter or device. These observations help determine whether suction is effective while maintaining the safety goals of the procedure.
