まとめ
新生児の正圧換気 (PPV) 時に完全に膨らんだ顔面マスクを使用すると,部分的に膨らんだマスクと比較して,施す力およびマスクの圧力が減少する可能性があります. 実際の利益を確認するにはさらなる研究が必要です.
科学分野:
- 新生児の蘇生
- 小児重症室
- 医療機器工学
背景:
- 最適な顔面マスクの膨張は 新生児の効果的な蘇生に不可欠です
- 顔面マスクの空気クッションの量の変動が,正圧換気 (PPV) 中の施加力と密封に与える影響に関するデータは限られている.
- これらの要因を理解することで,新生児の患者の安全性と換気効果を向上させることができます.
研究 の 目的:
- PPV中に部分的に (25 ml) と完全に (35 ml) 膨張されたフェイスマスクの間で,新生児のマンキンの顔,マッチングの圧力,および空気漏れに適用される力を比較する.
- マスクの密封,疲労,さまざまなインフレ量に対する全体的な満足度に関する参加者の認識を評価する.
主な方法:
- クロスオーバーのランダム化対照試験は,新生児用マニキンで行われました.
- 28人の新生児科医と小児科医は 部分的に膨らんだか完全に膨らんだマスクを使って PPV を実施した.
- 主な結果: マンキンの顔に力を加える. 二次的結果:マッシュプレッシャー,漏れ率 <25%の換気時間,参加者のフィードバック.
主要な成果:
- 部分的に膨らんだマスクで と頬骨に強い力を加えた.
- 部分的に膨らんだマスクでは,中位および上位10パーセントマスクの圧力が上昇しました.
- 適切なマスクシール (<25%の漏れ) を使った換気時間の有意な差は認められなかった.
結論:
- 完全に膨らんだマスク (35 ml) は,マニキンの部分的に膨らんだマスク (25 ml) と比較して,新生児のPPV中に施された力およびマニカーの圧力を軽減することができます.
- 参加者は両方のマスクインフレ量に似た経験と満足度レベルを報告した.
- 力の減少は潜在的利点ですが,実際の臨床効果についてはさらなる調査が必要です.

Oxygen Delivering System I: Nasal Cannula and Face Mask
582
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:...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical Ventilation II: Invasive Ventilation

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Mechanical Ventilation I: Indication and Settings

Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
951
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,...
