- 呼吸系统药物 呼吸系统药物
- 传染病的传播是传染病的传播.
- 气溶科学是一门气溶科学.
背景情况:
- 人类在呼吸和说话等活动中释放出呼吸道颗粒,这些颗粒可以传播病原体.
- 气管切除术通过绕过上呼吸道来改变空气流,但其对气溶产生的影响尚不清楚.
研究的目的:
- 为了在各种呼吸活动中比较气溶颗粒排放的气管切除术和健康个体.
- 为了研究气溶排放的差异在不同的活动在气管切除组内的不同.
主要方法:

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
2.9K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System III: Tracheostomy and T-piece
7.4K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Physical Assessment of the Respiratory Tract IV: Auscultation
2.9K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
