Manual ventilation devices can cause rebreathing of carbon dioxide, leading to hypercapnia. Vigilant monitoring of end-tidal carbon dioxide is crucial for critically ill patients to prevent adverse outcomes.
Area of Science:
- Critical Care Medicine
- Respiratory Therapy
- Biomedical Engineering
Background:
- Bag-mask resuscitators with manometry reduce pulmonary injury risk during manual ventilation.
- Preventing carbon dioxide rebreathing is essential, as hypercapnia is harmful to critically ill patients.

Oxygen Delivering System I: Nasal Cannula and Face Mask
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.

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.
Equipment
The equipment necessary for this procedure includes:
Acute Respiratory Failure-III
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,...

The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...
