Postoperative pulmonary complications remain common after surgery. The individualized open-lung approach to mechanical ventilation may reduce these complications by preventing lung collapse.
Area of Science:
- Anesthesiology
- Critical Care Medicine
- Pulmonary Medicine
Background:
- Postoperative pulmonary complications (PPCs) are frequent despite advances in anesthesia and surgery.
- PPCs increase patient morbidity, mortality, hospital stays, and healthcare costs.
- Anesthesia-induced atelectasis is a key factor contributing to PPCs.
Discussion:
- Lung protective ventilation strategies aim to mitigate PPCs.
- Two main hypotheses exist: reducing tidal volume/pressure with minimal PEEP, or actively resolving atelectasis with lung recruitment and individualized PEEP (open-lung approach).
- The individualized open-lung approach actively addresses atelectasis, unlike strategies that tolerate lung collapse.
Key Insights:
- Atelectasis during anesthesia can lead to lung damage during mechanical ventilation.
- Lung protective ventilation is a modifiable factor to reduce PPCs.
- The individualized open-lung approach represents a promising strategy for preventing PPCs.
Outlook:
- Further research is needed to fully understand the benefits and optimal application of the individualized open-lung approach.
- Personalized lung protective ventilation strategies are proposed.
- The goal is to reduce the incidence of PPCs and improve patient outcomes.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
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,...
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
