What causes gastric inflation in CPR?

There is a risk of gastric inflation with all airway and ventilation techniques during cardiopulmonary resuscitation. Positive pressure ventilation via a laryngeal mask airway can cause gastric inflation, particularly if the airway is not positioned correctly and if the inspiratory pressure exceeds 20 cm H2O.

Can chest compressions cause gastric distention?

Stomach perforation may develop as a complication of chest compressions in a patient with stomach distention, which is caused either by long periods of bag- valve mask ventilation or esophageal intubation in an emergency setting [1–3].

How can we minimize gastric inflation during bag mask ventilation?

To prevent gastric inflation the airway must be kept open, and breaths delivered slowly… very slowly. Based on my observations no one delivers breaths slow enough. When your own heart rate is going 150 beats per minute, waiting 6 seconds to deliver a breath feels like forever!

How can Rescuers reduce gastric inflation?

Rescuers can reduce the risk of gastric inflation by avoiding giving breaths too rapidly, too forcefully, or with too much volume. During high-quality CPR, however, gastric inflation may still develop even when rescuers give breaths correctly.

What is the correct ventilation rate for CPR?

Chest Compressions The compression-ventilation ratio for 1- and 2-rescuer CPR is 15 compressions to 2 ventilations when the victim’s airway is unprotected (not intubated) (Class IIb).

Is CPR 15 compressions to 2 breaths?

Two-person CPR for the adult victim will be 30 compressions to 2 breaths. Two-person CPR ratio for the child and infant will be 15 compressions to 2 breaths. Finger placement for the Infant changes to Two-Thumb Technique.

What is gastric distension?

Gastric distension is the enlargement of the stomach, and can be due to a number of causes. Physiologic (normal) gastric distension occurs when eating. Distension of the upper stomach stimulates the secretion of stomach acid, while distension of the lower stomach stimulates gastrin secretion.

What is the maximum interval for pausing chest compressions?

Make sure to minimize interruptions in chest compressions and avoid excessive ventilation, using a 30 to 2 compression-to-ventilation ratio if no airway is established. Rhythm shockable? Conduct a rhythm check, making sure the pause in chest compressions is not more than 10 seconds.

What is the correct ventilation rate?

The normal respiration rate for an adult at rest is 12 to 20 breaths per minute. A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.

Why is CPR 30 compressions and 2 breaths?

One of the biggest changes in the guidelines – implemented in 2005 – was to move from 15 compressions/2 breaths (15:2) to 30:2. The intention was to increase the number of chest compressions delivered per minute and reduce interruptions in chest compressions.

What is the ratio of 1 person CPR?

30 compressions to 2 breaths
CPR ratio for one-person CPR is 30 compressions to 2 breaths ▪ Single rescuer: use 2 fingers, 2 thumb-encircling technique or the heel of 1 hand. After each compression, allow complete chest recoil.

What is the ratio for 2 person CPR?

Two-person CPR for the adult victim will be 30 compressions to 2 breaths. Two-person CPR ratio for the child and infant will be 15 compressions to 2 breaths.

What causes gastric distention in a rescuer?

Gastric distention can be caused by the rescuer delivering the ventilations with too much force, by improperly positioning the casualty’s head (airway not open), or by an obstruction in the casualty’s airway preventing his lungs from filling quickly.

How can gastric distention be avoided during CPR?

Gastric distention can often be avoided by proper, careful administration of rescue breathing during CPR. Rescue breathing during CPR provides air directly into the lungs of the victim. Gastric distention causes the stomach to swell and places pressure on the lungs.

When does gastric distension occur in the body?

Physiologic (normal) gastric distension occurs when eating. Distension of the upper stomach stimulates the secretion of stomach acid, while distension of the lower stomach stimulates gastrin secretion 1). Distension of the stomach also stimulates the secretion of ghrelin 2).

What causes bloating in the stomach during resuscitation?

Gastric distension is bloating of the stomach when air is pumped into it. This may be done when someone is performing cardiopulmonary resuscitation and blowing air into the mouth of someone who is not breathing spontaneously. The primary reason this occurs is too much air is delivered during rescue breathing.
