There Are Some Common Oxygen Inhalation Methods

May 19, 2018

1. Nasal and nasal catheterization.

This method of oxygen absorption is simple and easy to use.Congestion method with single and double seal two kinds: single plug method to choose the suitable type of plug in the side of nasal vestibular, and closely contact with nasal cavity (the other side open nostrils), inhale into oxygen, so the oxygen concentration is stable.The two smaller noses were placed at the same time with both sides of the nose, and there was a gap around the nasal obstruction, breathing air at the same time. The patient was comfortable, but the oxygen concentration was not stable enough.Nasal catheterization is to insert a catheter through the nose into the back of the nasal tip of the soft palate, with a constant oxygen concentration, but with a long time of discomfort and easy to be blocked by secretions.Nasal and nasal catheterization is generally only suitable for low flow oxygen supply. If the flow rate is large, it can not withstand the impact of air flow, and it is easy to cause the airway mucosa to dry.

2. Mask inhalation method.

Can be divided into open and closed mask method.Open mode is to put the mask in the nose 1 ~ 3cm from the nose, suitable for children, without any discomfort.The closed mask method is to close the mask tightly to the mouth and nose and fasten with elastic band, suitable for severe hypoxia, the oxygen concentration can reach 40% ~ 50%, and it feels comfortable, without mucous stimulation and dry blowing sensation.However, the oxygen consumption is large, and there are disadvantages of eating and removing phlegm.

3. Endotracheal tube oxygen therapy.

It is an oxygenation method that is inserted into the trachea through the nasal passage with a narrow catheter, also known as endotracheal oxygen therapy.It is mainly suitable for chronic obstructive pulmonary disease and pulmonary interstitial fibrosis etc. Chronic respiratory failure requires long-term oxygen inhalation and general oxygen therapy ineffective.Because of the direct supply of oxygen to the trachea by catheter, it can significantly improve the therapeutic effect. Only the low flow oxygen supply can achieve a high effect, and the oxygen consumption is small.

4. Electronic pulse oxygen therapy.

It is a new method developed in recent years. It can automatically deliver oxygen during the inhalation period via electronic pulse device, while the expiration date automatically stops the oxygen delivery.This is more in line with the physiological state of the breath, and it saves a lot of oxygen.Suitable for nasal obstruction, nasal catheter and oxygen therapy.

5. Mechanical ventilation to oxygen method.

When mechanical ventilation is carried out with various artificial respiration machines, oxygen therapy is carried out on the oxygen apparatus on the ventilator.The concentration can be adjusted according to the condition.The oxygen source of oxygen therapy is usually multi-purpose oxygen cylinder, and equipped with the pressure gauge to indicate the oxygen content in the bottle, the installation flow meter for oxygen, and adjust the oxygen flow according to the need.Most hospitals now use centers for oxygen, and the switch is on the wall, which is more convenient.

6. Oxygen tent method.

Generally used in pediatric rescue, when there is no oxygen tent, the plastic film can be used to make a 

tent, which is about half the size of the hospital bed, and the oxygen is passed into the account by the rubber tube through the humidifying bottle.
