背景情况:
- 像流感和犀牛病毒这样的呼吸道病毒对温度敏感.
- 鼻热术将加热的,加湿的空气输送到呼吸道,潜在地抑制病毒复制并减少疾病的严重程度.
- 鼻热术对鼻喉温度的确切影响仍然不确定.
研究的目的:
- 为了研究鼻热疗法 (41°C加湿的空气) 对鼻喉空气空间温度的影响.
- 为了确定鼻热术是否能在鼻呼吸期间达到设定点的1.5°C以内的目标温度.
主要方法:
- 这是一项单中心,非盲目的,非随机的研究,涉及12名参与者.
- 在鼻热疗法 (41°C,30-35 L/分钟) 和假鼻热疗法 (31°C,10 L/分钟) 期间持续测量鼻空气空间温度.
- 对两个干预措施的鼻口呼吸期间温度变化的比较.
主要成果:
- 在41°C的鼻热术期间,鼻的平均温度为37.9°C (SD 1.22°C).

01:29Suctioning the Nasopharyngeal Airway
237
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.

01:30Epistaxis
118
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

01:14Temperature Measurement Sites
1.5K
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...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
868
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...
