BiPAP: (IPAP, EPAP), Principle, Operation, Pros, Cons, Handling


BiPAP stands for Bilevel Positive Airway Pressure. It is a kind of non-invasive fine pressure air flow. Unlike the CPAP system, it provides levels of air pressure to the affected person. In evaluation to the CPAP device, the BiPAP gadget may also have the function of the CPAP. Besides that, it can additionally have the features of the APAP. Hence, in terms of features, it’s far higher to shop for the BiPAP machines in place of buying a CPAP. Here, we will be speaking approximately the running mechanism, settings, operation tactics, professionals, cons, dealing with, and the list of legal dealers with a purpose to purchase the system in best bipap machine Kathmandu, Nepal.

Levels of pressure
Inspiratory Positive Airway Pressure (IPAP):- It is the strain this is implemented at some point of suggestion. The set fee for IPAP generally stages from 10 to 20 cm H2O.
Expiratory Positive Airway Pressure (EPAP):- It is the strain this is carried out all through expiration. The set cost for EPAP generally levels from 5 to 12 cm H2O.
(Inspiration is an active manner that desires more strength than expiration. Similarly, expiration is a passive procedure that does not want plenty power. Thus IPAP is constantly extra than EPAP.)

BiPAP Setting
1. Modes of BiPAP
CPAP mode:- Provides a unmarried non-stop airway strain in the course of idea and expiration.
APAP mode:- APAP stands for Auto CPAP. It is an advanced model of the CPAP mode. Here, the machine will mechanically set and trade the CPAP pressure based totally on the requirement of the patient.
S mode: Spontaneous mode in which the patient controls the breathing cycle.
T mode: Timed mode in which the alteration between IPAP and EPAP is based at the set time.
S/T mode: It is a combination of both the spontaneous and timed mode. If the patient is not able to respire spontaneously inside the set time, the timed mode will paintings. Else, the spontaneous mode will function.
2. Parameters
Different fashions of the device allow the users to set one of a kind parameters. Some, of the primary ones, are as follows:

EPAPmin = 4 cm H2O
IPAPmax = 20 cm H2O
PSmin = 3 cm H2O
PSmax = 15 cm H2O
(Note:- Even although there are more than one parameters within the machine, you honestly do no longer want to regulate those values for most of the cases. The widespread parameters which you need to worry about is the IPAP and the EPAP stress.)

The machine also can have the following capabilities.

Inspiratory to Expiratory (I: E) Ratio
Actual Breathing Rate
Estimated Tidal Volume, Minute Volume, and Air Leakage
No. Of Apneas
Alarm button, alarm reset, and so on.
Difference between CPAP and BiPAP
( BiPAP VS CPAP )

CPAP BiPAP
Stands for Continuous Positive Airway Pressure Stands for Bilevel Positive Airway Pressure
It continuously presents a unmarried airway strain to the affected person. However, the set cost can be changed as in step with the requirement of the patient. It constantly provides airway pressures to the affected person. One is for the duration of the foundation, while the other one is for the duration of expiration.
CPAP is useful for the treatment of patients with everyday respiration troubles including sleep apnea. If the situation of the affected person turns into an awful lot greater complex, then BiPAP is higher.
Since a single high nice strain is carried out constantly, expiration is probably difficult. Since a decrease airway pressure is applied in the course of expiration, respiration will become much less complicated.
It is inexpensive to buy It is plenty more high priced in evaluation to the CPAP.

BiPAP Mask
Mainly, two styles of BiPAP masks are in use.

Full Face Mask
Nasal Mask
These masks are also utilized in CPAP machines.
