Summary
Properly sized facemasks are crucial for effective neonatal stabilization. This study found that 42mm and 50mm round facemasks fit most near-term and term infants, respectively, improving ventilation seal.
Area of Science:
- Neonatal care
- Pediatric respiratory support
- Medical device sizing
Background:
- Inappropriately sized facemasks can compromise ventilation during neonatal resuscitation.
- Accurate facemask selection is vital for effective neonatal stabilization.
Purpose of the Study:
- To determine appropriate round facemask sizes for near-term and term infants.
- To measure facial dimensions using 2D and 3D imaging for facemask selection.
Main Methods:
- Prospective observational study involving infants born at 34-41 weeks' gestation.
- Utilized 2D and 3D imaging to measure facial dimensions (nasion to gnathion).
- Compared infant facial measurements with outer diameters of standard round facemasks.
Main Results:
- 102 infants were analyzed; mean gestational age was 37.9 weeks.
- 3D imaging revealed larger facial dimensions than 2D imaging (mean difference of 3mm).
- 50mm masks fit 61% of term infants; 42mm masks fit 72% of near-term infants (34-36 weeks GA).
Conclusions:
- 60mm round facemasks are generally too large for newborns.
- 42mm and 50mm round facemasks provide a better fit for near-term and term infants, respectively.
- 3D imaging offers superior visualization of anatomical structures for precise measurement.

01:22PPE Use in Healthcare Settings I: Donning
1.6K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

01:26Oxygen Delivering System I: Nasal Cannula and Face Mask
1.5K
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.

01:20Personal Protective Equipment
2.2K
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

01:10PPE Use in Healthcare Settings II: Doffing
1.6K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

01:14Temperature Measurement Sites
3.2K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
