Oxygen Delivering System I: Nasal Cannula and Face Mask01:26

Oxygen Delivering System I: Nasal Cannula and Face Mask

911
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Cardiopulmonary Resuscitation II: ACLS Airway Management

261
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...

Administering Oxygen by Nasal Cannula

1.5K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Summary

Aerosol generating medical procedures during newborn resuscitation can disperse particles widely. Using particle filters and cuffed endotracheal tubes can reduce this risk for healthcare workers.

Area of Science:

  • Neonatal resuscitation
  • Infectious disease transmission
  • Aerosol science

Background:

  • Aerosol generating medical procedures (AGMPs) are common in neonatal resuscitation.
  • Neonates with infections like SARS-CoV-2 pose risks to healthcare workers.
  • Limited data exists on minimizing aerosol dispersion during neonatal AGMPs.

Purpose of the Study:

  • To quantify expiratory airflow dispersion during common neonatal resuscitation AGMPs.
  • To evaluate methods for mitigating aerosol dispersion during these procedures.

Main Methods:

  • Simulated expiratory airflow dispersion using infant manikins (term and preterm).
  • Utilized fine particle smoke and measured dispersion distances with ImageJ.
  • Assessed various airway procedures including endotracheal tube (ETT) and T-piece ventilation.

Main Results:

  • Maximal dispersion distances reached up to 30.2 cm (term) and 22.1 cm (preterm) in unsupported airway scenarios.
  • Cuffed ETTs combined with filters eliminated expiratory dispersion and minimized leak.
  • Angulated T-pieces generated the greatest dispersion distances.

Conclusions:

  • Airflow dispersion during neonatal AGMPs is significant and poses a potential contamination risk.
  • Particle filters and cuffed ETTs can effectively mitigate this risk.
  • Further clinical evaluation is needed to confirm applicability.
