Insights

Continuous distending pressure (CDP) reduces respiratory failure and mortality in preterm infants with respiratory distress syndrome (RDS). However, CDP use is linked to an increased risk of pneumothorax, necessitating further research for modern applications.

Area of Science:

  • Neonatal Medicine
  • Pediatric Pulmonology
  • Critical Care

Background:

  • Respiratory distress syndrome (RDS) is a primary cause of illness and death in preterm infants.
  • Intermittent positive pressure ventilation (IPPV) is standard but invasive, causing lung injury and chronic lung disease.
  • Continuous distending pressure (CDP) offers a less invasive alternative.

Purpose of the Study:

  • To evaluate if continuous distending pressure (CDP) reduces the need for IPPV in spontaneously breathing preterm infants with RDS.
  • To assess associated morbidities and adverse effects of CDP compared to standard care.

Main Methods:

  • Systematic review of randomized and quasi-random trials of CDP (CPAP or CNP) versus standard care in newborn infants with RDS.
  • Searches included major databases (MEDLINE, Cochrane Trials) and expert consultations.
  • Data were independently assessed for quality and extracted by authors.

Main Results:

  • CDP use was associated with lower rates of treatment failure (death or need for ventilation) and overall mortality.
  • Infants weighing over 1500g showed reduced mortality with CDP.
  • An increased incidence of pneumothorax was observed with CDP application.

Conclusions:

  • CDP (CPAP or CNP) offers benefits in reducing respiratory failure and mortality in preterm infants with RDS.
  • A significant increase in pneumothorax risk is associated with CDP.
  • The applicability of findings from the 1970s is limited due to outdated methods and lack of modern interventions (surfactant, antenatal corticosteroids).
  • CPAP may be valuable in resource-limited settings; further research is needed for current intensive care practices.

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Pressure Relationships in Thoracic Cavity

Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...

Ventilatory Modes

Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Pulmonary Ventilation: Inhalation

Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.
Boyle's law becomes particularly pertinent when examining respiratory...
